Andover, United Kingdom – Inseto, a leading technical distributor of equipment and materials, has been appointed Kulicke & Soffa’s exclusive distributor for high-quality hubbed dicing blades in Austria, Germany, the Netherlands and Portugal. This appointment extends Inseto’s geographical remit as the company has been supplying K&S dicing blades – as well as wire and wedge bonders, dispensing equipment and die bonders – in the UK and Ireland since 2008.
Kulicke & Soffa’s exclusive distributor for hubbed dicing blades in the UK and Ireland since 2008, Inseto’s remit has been extended to include Austria, Germany, the Netherlands and Portugal.
Hubbed dicing blades are used for cutting semiconductor wafers into individual die and are available with various grit sizes, diamond concentrations and binder hardnesses.
“We’re delighted to have been appointed to distribute K&S’s high quality hubbed dicing blades in Austria, Germany, the Netherlands and Portugal,” comments Matt Brown, Director of Inseto. “These are countries in which our technical specialists are already well known and supporting customers active in semiconductor manufacturing.”
Inseto has been supporting companies in the UK and Ireland with dicing blades for 16 years and is well versed in all technical aspects of wafer dicing. For example, silicon is a relatively soft material and single pass cuts are possible in most cases whereas as compound semiconductors, such as silicon carbide and gallium nitride, are harder and more brittle, often requiring multiple cuts to minimise the risk of sidewall cracking and chipping.
Kulicke & Soffa’s exclusive distributor for hubbed dicing blades in the UK and Ireland since 2008, Inseto’s remit has been extended to include Austria, Germany, the Netherlands and Portugal.
Brown adds: “Cut quality is governed by the size of the diamonds in the blade, the rate at which the binder material releases them – i.e. blade wear – the RPM at which the blade is spun and the rate at which it is moved through the wafer. Cooling and the use of surfactants also have an effect on cut quality, so there are lots of permutations to consider, and having gone to the expense of fabricating wafers it is important not to damage any die during the dicing process.”
As a supplier of dicing saws and a variety of processing equipment, Inseto can also advise customers early on in their projects on issues such as optimum ‘street’ widths between die, as there is understandably a trade-off between getting as many die as possible on a wafer and being able to cut between them without causing damage. Inseto is also a supplier of semiconductor wafers and has a dedicated online store.
“Our appointment by K&S to distribute hubbed blades in four more countries in Europe is great news in itself,” concludes Brown, “but it’s also broader recognition that Inseto has in-house expertise in all aspects of semiconductor manufacturing and that we’re able to help customers achieve a great economy of scale and return on investment.”

First there were light-cured adhesives, then light-activated adhesives, and now we have dual-cure adhesives. Eamonn Redmond, Director of Inseto, provides an overview of all three.
Though what we’re about to discuss has been the subject of articles before, it’s always worth having a refresher. Also, while many of the overarching principles of bonding have not changed over the years, adhesive chemistries have – which means things like open times (see later) have increased.
‘UV adhesives’ is the generic term used when referring to an adhesive that requires high-intensity light for curing. A significant proportion of these adhesives actually uses light in the visible spectrum for curing. Indeed, it is typically the visible component of the photoinitiator that is used to achieve the cure. This is useful when bonding polycarbonate, for example, as most grades of this material block UV light.
Regardless of where on the spectrum the photoinitiator lies, the simple fact is that one of the parts being bonded must be transparent to allow for 100% cure of the adhesive (see figure 1). No one likes having uncured adhesive in their products on a long-term basis, especially as a number of these adhesives are based on acrylic acid, which is rendered harmless by curing but is hazardous in its liquid state.
Figure 1 – Light curing requires one of the substrates to be transparent. (Image courtesy of DELO.)
When bonding components together, it is essential that the whole volume of the adhesive is fully cured, as uncured adhesive in the finished assembly may cause corrosion or, in the case of optical products, interfere with the light path. However, achieving full cure can be a problem due to shadow areas that light cannot reach.
In this respect, dual cure adhesives can help and there are many on the market that offer significant advantages over more traditional adhesives without sacrificing reliability, bond strength or ease-of-use. Uses include industrial displays, automotive camera modules, electric motors and even simple applications such as thread-locking. Let’s take a look at the two most popular dual cure methods.
Dual Cure: Light & Humidity
These adhesives are used when temperature-sensitive materials are being joined, but they are limited by the fact that the majority of the adhesive in the bond area must be cured by light and by the fact that the humidity-responsive portion of the adhesive cures at a slow rate (typically about 2mm every 24 hours), which is similar to the rate at which silicone adhesives cure.
They are single-part adhesives and are free of isocyanates (so present no health and safety issues) and are free of silicones too (so no impediment to subsequent adhesive bonding), unlike some acrylates. They are highly flexible, optically clear and offer excellent climatic resistance, whilst also providing excellent bond strength on surfaces such as glass, PMMA, metal pins and most plastics.
Dual Cure: Light & Heat
These are based on two diverse chemistries, epoxies and acrylates.
Epoxies tend to be hard once cured, offering increased resistance to chemical and temperature stresses due to the tight cross-linking of the polymer that occurs during cure.
Acrylates are usually softer adhesives, enabling quicker curing and greater flexibility of the cured adhesive.
Using a combination of heat and light to cure these adhesives offers a very fast fixation by snap-curing the photoinitiator in the adhesive. Subsequent heat curing ensures that there is no uncured adhesive in any shadow zones that might exist in the assembly. This fast fixation also allows increased accuracy, which is especially useful for companies that have invested heavily in high-accuracy placement machines only to see movement of the parts being bonded during the heat-cure stage.
The heat-cured stage generally involves heating the parts up to around 100°C after the light cure process. However, for temperature-sensitive materials such as some plastics, modified epoxy adhesives are available that will cure at 60°C, combining defined processes and short cycle times, despite the low curing temperature of the adhesive.
These are especially useful in applications such as automotive camera modules, or where the end product is subjected to chemical influences that would otherwise harm an acrylate adhesive. These dual-cured epoxies also exhibit very low outgassing and low yellowing, making them ideal for applications with demanding optical requirements, such as LED assembly.
Dual-cured acrylates offer similar advantages to dual-cured epoxies, namely very fast fixing and full cure after subsequent heat curing, but they also exhibit excellent impact resistance and tension-equalising properties due to their flexible nature. These are suitable for applications such as the assembly of rotary encoders, where optional fluorescing and colouring can be added to aid visual inspection.
Light and heat cured adhesives also offer increased flexibility in the manufacturing process. While heat-curing is mandatory for a small number of these adhesives, the majority offer independent curing mechanisms, allowing curing by light, by heat or a combination of the two.
They do not suffer from the same limitations as light and humidity cured adhesives, however, a downside is the minimum cure temperature is a strict 80°C, which means heating the oven to at least 83°C to avoid any potential cold spots. This is strongly recommended because if the adhesive does not reach 80°C its heat-cured portion will never cure, regardless of how long the parts to be bonded remain in the oven. The time to cure at elevated temperatures can also be a factor. For example, curing at an oven temperature of 83°C might take up to one hour, but at 150°C the cure time might be as short as 10 minutes.
Unfortunately, many modern low-cost plastics are heat sensitive and even 80°C might be a problem. Two-part cold-cured adhesives, such as epoxies and polyurethanes, can overcome this issue but the penalty is long curing times.
Light Activation
For applications where the cycle time needs to be short – i.e., to avoid lengthy humidity or heat cure times – this is where light-activated adhesives come into their own.
The process is simple. Dispense the adhesive onto substrate A, illuminate it with high intensity light for a short period of time, and place substrate B onto the adhesive. Both A and B can be non-transparent.
Illuminating the adhesive provides enough energy to trigger the curing process. However, if too much energy is provided, there will not be enough time to place the second substrate before a skin forms on the surface of the adhesive. Once this happens, it is impossible to bond the substrates.
The time it takes for the skin to form on the adhesive is called the open time. It is measured from when the illumination ceases to when the skin forms. Increasing the energy provided to the adhesive, whether by increasing the intensity of the light or by illuminating for longer, reduces the open time.
Unfortunately, the relationship between the activation energy and open time is not linear. Factors such as substrate material, colour, smoothness and reflectivity all have an impact on the open time. The technical datasheet of the adhesive will indicate a range of open times. For example, the technical data sheet for DELO KATIOBOND 4594 states that an open time of 15 to 20 seconds results from an illumination time of 3 seconds when using a DELOLUX LED lamp with a light intensity of 200 mW/cm2, measured at the adhesive.
Changing the lamp, the illumination time or materials will affect the open time, which should be measured. Also, it’s worth noting that if one the materials being bonded is metal, then it will be necessary to heat it up slightly, to say 35°C. This is because the heat generated within the adhesive during the activation process will be conducted away and slow down the reaction significantly. It may even prevent the reaction completely.
Once the substrates have been joined, full cure will take place over time, typically 24 hours. However, we did say above that light-activated adhesives are ideal for shortening the cure time, and they are because the cure process can be accelerated by:
Depending on the geometry of the parts being bonded, additional light curing is possible. For example, if there is a fillet of say 0.5mm of adhesive around the joint, a second light cure process can be carried out immediately after bonding (see figure 2). This increases the bond strength, allowing the assembly to be moved on to the next process.
Alternatively, the assembled parts can be heated (also shown in figure 2). This can seem contradictory as light-activated adhesives are used for the very purpose of eliminating heat from the process. But even the addition of low levels of heat can have a significant effect on the cure speed. As a general rule, for every 10°C increase in cure temperature, the cure time is halved. So, increasing the temperature of the bonded parts to even 45°C (i.e., safe enough even for the modern temperature sensitive materials I mentioned earlier), can reduce the cure time to 6 hours, while ensuring that there is sufficient handling strength in the adhesive to safely carry out the next (assembly) process step.
Figure 2 – Above, an illustration of a camara module being bonded to a substrate. Following activation of the adhesive and placement of the module, further curing can be achieved using light shone through the sides of the fillet or through the application of heat. (Image courtesy of DELO.)
A recent development on the light-activated adhesives front is ‘activation on the flow’, announced by DELO in 2022. The technology combines adhesive dispensing and pre-activation in a single process step and is considered particularly suitable for bonding and encapsulating temperature-sensitive electronic components.
Another benefit of adding irradiating to the dispensing step is that the exposed adhesive areas can be additionally irradiated (as discussed above) and fixed after joining. This provides immediate initial strength, preventing the adhesive from flowing out and the components from slipping, which allows them to be further processed immediately. Whether with or without additional light fixation, the adhesive cures reliably to final strength without any additional process step, even in undercuts and shadowed areas. For further information on this see FAST magazine news from 25th July 2022.
Summary
So, what has this refresher taught us? Traditional light (only) cured adhesives need one of the substrates to be transparent. Light and humidity dual-cure adhesives overcome the problem but take time to cure. Light and temperature dual-cure adhesives take less time to cure but cannot be used with many heat-sensitive materials.
Light activation, the new kid on the block, initiates the curing process (and marks the start of the ‘open time’). Full cure takes time, but the process can be accelerated using light (subject to it being able to penetrate) or heat (subject to the substrates not being heat-sensitive, though lower temperatures can be used compared to light and temperature dual-cure adhesives).
‘UV adhesives’ is the generic term for adhesives that require high-intensity light for curing. For many though, it is light in the visible spectrum that does the curing. (Image courtesy of DELO.)

Figure 1: Ultrasonic wirebonding is an ambient temperature (‘friction weld’) process, so does not run the risk of damaging the cell. Bond integrity/quality is the product of the physical force and ultrasonic energy (i.e., power over time) applied. These parameters are controlled to ensure the bond takes and can even be adjusted to account for some levels of surface contamination.
Electromobility (e-mobility), the move away from using internal combustion engines in cars, bikes, buses and trucks etc., requires batteries to store and release power. The properties of a battery, or rather a battery pack, are therefore largely responsible for setting the vehicle’s performance. Storage capacity defines range and the rate at which power can be released sets acceleration.
In addition, the rate at which the battery pack can accept power determines charge times (in the case of battery EVs [BEVs] and plug-in hybrid EVs [PHEVs], for example) and how much power can be recovered through regenerative braking (in the case HEVs, PHEVs and range extended EVs [REEVs], for example).
A typical battery pack in something the size of a car comprises multiple battery modules, connected using bars, bolts and/or heavy gauge cables, arranged in parallel and series combinations to produce the desired energy and power characteristics. Each module can contain anywhere between a few and more than a thousand cells.
Consider these stats for the battery pack of the Tesla Model S Plaid. It has 99kWh total capacity, of which 95kWh is usable. It has five identical power modules. Each module contains 22 rows (i.e., series connections) of 72 cells placed in parallel (i.e., within each row). This equates to 1,584 cells per module and 7,920 for the pack. Each cell is a Panasonic lithium-ion 18650-type, so larger in diameter and length than a standard AA cell.
Not surprisingly, a vehicle’s battery pack accounts for much of its cost. For a BEV, that can be more than one third. With material costs more or less the same across the industry, all battery pack manufacturers are keen to make their products as cost-effectively as possible. However, they cannot compromise on durability or safety. And regarding this last point, ISO 26262 functional safety standard applies to the battery management systems (BMS) within or working alongside battery packs.
Connections
As mentioned in the Tesla battery example, several cells are placed in parallel. This is typically achieved by connecting the terminals of the cells to busbars. This tends to be done in one of two ways.
Laser welding. Each busbar is placed in physical contact with the respective terminals of all cells to which it is to be connected. Tooling can be an issue to account for any cell height tolerances. Also, as it is a traditional weld process, the objective is to heat metals until they fuse together. Here, there’s a risk that localised heat from the welding process penetrating the negative terminal can alter the cell chemistry and lead to catastrophic thermal runaway. NB: cell positive terminals are ‘floating’, so less vulnerable because of the air gap.
Ultrasonic wirebonding (see figure 1). The process is already dominating power electronics manufacturing as a flexible and robust method of making electrical interconnects in hybrids, switches and regulators; and it dominates the microelectronics industry. Also known as ‘friction welding’, there is minimal localised heating to the wire or battery surface and the process copes far better with tolerances in cell height (relative to the busbar). In addition, there are several industry specifications relating to wirebonding and bond quality that are being adopted within the automotive sector. For example, MIL-STD-883E, Notice 4, Method 2011.7 is a test to measure bond strengths. See figure 2.
Figure 2: Above, MIL-STD-883E, Notice 4, Method 2011.7 states the minimum forces to be applied during a bond wire pull test depending on the material and its diameter. This is a non-destructive test, and the bond wire is pulled midway along its length. Some wire bonders can perform the test, using a hook, as part of the bonding process so the quality of every bond can be checked during production.
As mentioned, durability and safety are key and, in this respect, ultrasonic wirebonding has an edge over welding. Depending on the vehicle’s intended environment of operation, the battery pack may be subjected to significant vibration and mechanical shock. Any interconnect technology used at the cell level must withstand the external forces expected, to ensure a good operational lifetime.
The bond wire tends to be high purity aluminium, with a diameter of between 0.2 and 0.5mm and has a degree of softness and flexibility (annealing). Note: multiple bonds can be made side by side to accommodate high currents.
As for safety, with a suitable diameter, a bond wire can act as a fuse and a failing/shorting cell will effectively self-isolate, thus reducing the risk of fire or explosion.
In Practice
As mentioned, keeping manufacturing costs down is an imperative. But it’s not just the likes of Tesla keeping a keen eye on production costs. For example, Steatite’s Power Business Unit has recently taken delivery of an Asterion EV wire bonder – see figure 3. Steatite specialises in the creation of custom battery packs, which often need to be of a particular size and shape.
The bonder gives Steatite the ability to establish electrical connections using wire bonding in up to half the time spot welding would take, in many cases. In addition, wire bonding makes possible the creation of battery packs with high discharge capabilities and improved performance, as a result of the very low resistance of the bond wire.
Steatite’s engineers have been successfully spot- and arc-welding battery pack components for several years. Spot-welding is, in particular, suitable for the vast majority of the company’s products, in which some parts are up to 3mm thick. Wirebonding is therefore a complement to welding in the manufacture of most battery packs.
On a general note, for any high value manufacturing process, the ability to rework process steps to improve assembly yield is important, especially in the initial prototyping and pilot production stages. In this respect, wirebonding has the edge. Failing or weak bonds can be easily reworked. Moreover, wire bonders like the Asterion EV can automatically perform wire pull tests to verify the bond has taken.
Reworking a failed or imperfect weld is more problematic as there will be more surface material to remove and the cell will be exposed to another temperature process as it is rewelded. Also, depending on its design and once in place, a busbar might not allow access to individual joints for rework purposes.
In summary, welding and wirebonding both have key roles to play in the construction of EV battery packs. As for which process to use, this depends on the pack architecture, ease of access to the parts to be connected, whether or not fuses are required, the ability to accommodate reworks, volumes being manufactured, production costs (including time) and the end application.

Inseto, a leading technical distributor of equipment and materials, has supplied and installed a Kulicke & Soffa (K&S) Asterion EV battery wire bonder at Leicester-based BPC Electronics to support its expansion into sectors in which battery packs are used.
BPC, a contract electronics manufacturer, is renowned for its electronic design and PCB assembly services and has the usual manufacturing equipment one would expect of a CEM; including pick and place machines, solder reflow lines and a vapour phase oven.
The company’s investment in the Asterion EV gives BPC additional assembly capabilities and, in particular, the ability to manufacture battery packs for electric vehicles (EVs), other forms of e-mobility and the static storage of power (on the domestic and small industrial scale) from renewables such as wind and solar.
The EV is part of a family of Asterion wire bonders (the largest of which has a bondable area of 760 x 1440mm), the members of which are all ideal for establishing the numerous electrical connections found in battery packs. The EV has a bondable area of 300 x 860mm, pattern recognition capabilities and is driven by a direct-drive motion system that requires minimum maintenance, provides for extremely tight process control and delivers high repeatability.
Mike Pitt, Sales Director of BPC Electronics, commented: “We’re already serving many sectors that use battery packs. We’re doing so by manufacturing circuit boards and cable harnesses, plus we do box builds. Offering battery pack design and manufacturing services is a logical expansion for us.”
BPC built a dedicated and spacious room for its Asterion EV, as the company envisages having a steady throughput of battery packs of varying shapes and sizes, and has already started building packs with 6, 12 and 24kWh capacities for a number of static energy storage applications. The company also plans to lease out time on its new wire bonder. “We have ambitious expansion plans,” concluded Pitt. “These include purchasing additional wire bonders in the future, as all the indicators are that our domestic markets are keen to have battery packs and associated products, such as battery management systems, that are designed, built and can be supported by companies here in the UK. Despite government incentives, investing in e-mobility and energy storage still requires a leap of faith. We give customers peace of mind because we’re a UK-based OEM that can develop, manufacture and supply most of what’s needed.”

Also, the support from Inseto – from their recommendation of the Asterion EV through to operator training – has been excellent.”
Carlton goes on to say that power failure is not an option in many of the critical applications for which Steatite designs and manufactures battery packs. Steatite battery packs can, for example, be found in products and equipment used in medical, industrial, oceanographic, energy and transport applications.
“With the Asterion EV we have the peace of mind that every cell leaving our factory having been wire bonded is safe, reliable and robust,” concludes Carlton. “This is enabling us to maintain our reputation for battery pack performance quality, a reputation we’ve secured over decades in the power business.”
