Inseto, a leading technical distributor of equipment and materials, has invested in a Kulicke & Soffa (K&S) Asterion wedge bonder. Located in Inseto’s new Process Development Laboratory along with materials test and plasma cleaning equipment, the automatic bonder is suitable for the large-wire, fine-wire and ribbon bonding of hybrid circuits, semiconductor devices, sensors, and automotive power modules and battery packs.

Inseto has also launched two training courses: one for wedge bonding, the other for ribbon bonding. Both are delivered by Inseto’s factory trained and highly experienced engineers. Course content is tailored to meet a trainee’s exact requirements and modules include bond theory, bonding tool and wire/ribbon selection, machine setup and operation, process development and bond quality control, and maintenance and repair.

Matt Brown, Inseto’s Managing Director, comments: “These are challenging times for manufacturers. To take full advantage of industry’s latest manufacturing techniques companies must first develop and optimise their processes. They then need to ensure they’re getting the most from their equipment when they move into volume production. Early access to best-in-class equipment and thorough training for operators are therefore essential.”

Brown goes on say that most equipment distributors simply carry demo machines – on loan from their suppliers and which they intend to sell. Inseto, on the other hand, is investing in kitting out its own Process Development Laboratory.

“While all distributors say they’re committed to supporting their customers, we’re demonstrating our commitment through investment,” continues Brown. “Our laboratory is a quiet environment that doesn’t have distractions you find in a manufacturing environment. And with our specialists to hand it’s the ideal place to build and evaluate prototypes, and to receive training.” Inseto’s Process Development Laboratory is fully operational. Also, the company is now taking bookings for its bonder operation training courses, which can be delivered on customer premises if required.

Inseto is exclusive distributor for Kulicke and Soffa’s range of wire bonding and die bonding equipment & materials in the UK, Ireland and Nordic regions.

Oxide wafer coatings: their properties and application methods

28th September 2021

Want to learn more about oxide wafer coatings, read our technical article published on LinkedIn HERE.

Thermal Oxide Wafer Processing
Thermal Oxide Wafer Processing

When applied to a wafer, an oxide coating adds a dielectric or passivation layer, needed to give a semiconductor, MEMS or BioMEMS device its desired electrical properties.
 
In our “Oxide wafer coatings: their properties and application methods” article, we discuss the two most common oxidation processes – Atmospheric Thermal Oxide (ATOx) and Plasma Enhanced Chemical Vapour Deposition (PECVD) – and provide examples of applications that benefit from both.
 
We discuss oxide growth rate, and how it is influenced by temperature, the presence of other chemicals (water/steam in the case of wet ATOx), doping and crystal orientation.
 
Also, did you know, that during the oxidation process, oxide grows into the wafer as well as onto its surface. For silicon, the ratio is about 46% into the surface and 54% on top of the original surface. In other words, the overall wafer thickness does not increase by the depth of the oxide layer, as some of the Si is consumed during the oxidation process.
 
Inseto produces and supplies an extensive range of high-quality semiconductor wafers and substrates worldwide, used for production and research purposes.

Adhesives for Battery Pack Production

24th September 2021

Inseto will be showcasing DELO’s range of adhesives at the Battery Tech Expo and Battery Technology Show this October.

Adhesives for Battery Pack Production
Adhesives for Battery Pack Assembly

Andover, United Kingdom – Used extensively in #EV #batterypacks, #adhesives play important roles. Here are just a few examples of what they are used for and the properties the adhesives must possess.

In carriers (pictured), adhesives are used for the bonding of cylindrical cells. Also, retainer bars are bonded onto the cells plus the carrier is bonded to a busbar. The adhesives also provide vibration protection and, hand in hand with that, help reduce noise.

The adhesives must also be flame retardant and bond to flame retardant materials. The coefficient of thermal expansion (CTE) needs to be close to that of the other materials, and curing time needs to be short for volume production scenarios.

Adhesives are also used for weld and pin sealing in #batterymodules and #powerpacks and provide corrosion protection. The power management electronics used in packs also use adhesives; for die-attach and to protect components.

If you’d like to know more, come and talk to us at any of the following shows in October

  • 12th – Battery Tech Expo at Silverstone
  • 19th & 20th – FAST Show (co-locating with EDS) in Coventry (Ricoh Arena)
  • 26th & 27th – Battery Technology Show in Coventry (Ricoh Arena)

Rapid™ Pro Ball Bonders from Kulicke & Soffa Help Filtronic to Meet a Significant Increase in Demand for RF Modules for 5G

18th May 2021

Kulicke & Soffa RAPID™ Pro automatic wire bonder installed in the Filtronic cleanroom

Inseto has supplied two Kulicke & Soffa RAPID™ Pro automatic wire bonders to designer and manufacturer of advanced RF communication solutions Filtronic. The two bonders are high speed and deliver high levels of repeatability, provided through real-time monitoring and diagnostics, and are helping Filtronic meet a six-fold increase in demand for its Orpheus E-band transceiver modules, used for 5G and other high data rate wireless applications, following an order from a major customer in the telecoms sector.

In addition to being used for the manufacture of Orpheus modules, the RAPID Pros are used on Filtronic’s next generation transceiver, Morpheus II, which is both smaller and 50% lighter than the previous version, enabling class leading 10Gbps mmWave backhaul.

The RAPID Pros enable fast switch over, giving Filtronic the flexibility to also manufacture two Transmit Receive Modules for phased array radars for the aerospace and defence markets on the same production line.

Richard Smith, Product Engineering Manager of Filtronic, comments: “All three of our main lines are hybrid assemblies, with multiple MMICs and other components that require high precision wire bonding. The RAPID Pro bonders help us solve two major manufacture challenges. The first being that, at these high frequencies, bond wire lengths and shapes affect the EM characteristics. Being able to precisely program the bond shape and maintain it within and between batches of a given product ensure consistent RF performance. Accuracy and repeatability are musts. The second challenge is maintaining throughput and increasing capacity. Since bringing in the K&S bonders we’ve seen a massive improvement in speed, largely down to the modern vision systems, and it takes about a minute to process a module with hundreds of bonds.

Bond quality has also improved because Filtronic has far better control over bond parameters than before. Smith concludes: “Automated bond adhesion quality is consistently higher, thus reducing the need for manual intervention. Combined with fast automated bonding, this results in an overall much higher production rate than before and we anticipate a return on investment in about three years”.

First Distributor in UK & Ireland to Supply SVHC-free Chip Encapsulation Adhesives for High Reliability Electronics Assembly Applications

8th March 2021

Inseto has written a free guide – ‘Likely Changes to Chip Encapsulation Adhesives’ – on this important topic.

SVHC Free Encapsulation Adhesive
SVHC-free DELO MONOPOX GE6585 and GE6525 are both ideal for chip encapsulation techniques such as Dam & Fill, as shown respectively in the above images.

Andover, United Kingdom – Inseto is the first distributor serving the UK and Ireland to supply chip encapsulation adhesives for high reliability applications that are free of substances of very high concern (SVHC). Easy and trustworthy access to SVHC-free adhesives made in the EU will become essential if, or more likely when, industry regulations come into force banning the manufacture of such products.

As DELO’s exclusive distributor in the UK & Ireland, Inseto can supply DELO MONOPOX GE6585 and GE6525, which are primarily used for Dam & Fill chip encapsulation, and DELO DUALBOND GE7065, which is mainly used for Glob Top chip encapsulation. All three cure to from rigid protective coatings and can be used for encapsulating not only semiconductor die but also sensors, which is a common practice in the automotive, aerospace and harsh environment industrial sectors, for example.

“Whilst not all chip encapsulation adhesives contain SVHCs, those that are needed to ensure high reliability do,” comments Eamonn Redmond, Sales Manager of Inseto. “And the European Chemical Association is constantly reviewing and working towards banning the use of SVHCs. Whilst it’s not certain when adhesives containing SVHCs will be banned they almost certainly will be. In addition, these new adhesives offer significant processing and performance upgrades over their SVHC-containing counterparts.”

DELO MONOPOX SVHC-free Globtop and Dam and Fill Adhesives
DELO MONOPOX GE6585, DELO MONOPOX GE6525 and DELO DUALBOND GE7065, available in the UK and Ireland through Inseto, are believed to be the first SVHC-free adhesives on the market for applications where high reliability is a necessity.

DELO MONOPOX GE6585, DELO MONOPOX GE6525 and DELO DUALBOND GE7065 are believed to be the first SVHC-free adhesives on the market for applications where high reliability is a necessity. They are offered as alternatives to existing DELO adhesives currently used for Dam & Fill and Glob Top chip encapsulation in applications where high reliability is important.

All three new adhesives have high shear strengths, low coefficients of thermal expansion (CTE), high glass transition temperatures (Tg), extended operating temperature ranges and an extremely high resistance to chemicals.

GE6585 and GE6525 are one-part heat-cured black epoxies. Compared to their SHVC-containing counterparts, the CTE has been nearly halved. However, the new adhesives retain the extremely high Tg of the existing adhesives (>170oC), making them ideal for high reliability applications; ensuring minimal risk of board warpage during assembly.

GE7065 is also a one-part heat-cured black epoxy with a low CTE and high Tg. It also has the added advantage of being light-fixable (optional) immediately after dispensing. In addition, the filler particle size is significantly reduced (to around 7μm), allowing the adhesive to flow more easily between very fine-pitch wire bonds.

All three new adhesives boast significantly shorter curing times than their SVHC-containing counterparts – 30 minutes at 100oC for GE6585 and GE6525, and 60 minutes at 130oC for GE7065 – and can be ordered now through Inseto.

Asterion Wedge Bonder Meets CIL’s Advanced Technology Group’s Requirements for Multiple Electric Vehicle Projects

2nd March 2021

Andover, United Kingdom Inseto, a leading technical distributor of equipment and materials, has supplied Custom Interconnect Limited (CIL) with a Kulicke & Soffa Asterion large diameter wire / ribbon wedge bonder for use in the production of wide bandgap (WBG) semiconductor-based power modules and the assembly of battery packs.

Kulicke & Soffa Asterion Wedge Bonder

The Asterion is to play a crucial role in two major electric vehicle (EV) projects in which CIL is extensively involved. In the first, CIL is engaged with BMW on APC15@FutureBEV to maximise potential for future BEV systems. The project is one of 10 projects by the Advanced Propulsion Centre (APC) in its latest round of Government and industry funding for low-carbon emissions research.

In the second case, CIL is the project lead on GaNSiC – a project that stems from the UK Research and Innovation’s (UKRI) ‘Driving the Electric Revolution’ challenge and brings together CIL and Compound Semiconductor Applications Catapult (CSA Catapult). It is set to develop novel ways of applying Silver Sinter pastes to WBG semiconductors, such as Silicon Carbide (SiC) and Gallium Nitride (GaN) devices, to optimise their thermal coupling and solve complex power module assembly challenges.

John Boston, Managing Director of CIL, comments: “Because of the high currents EV power modules handle, both projects require the placement of heavy gauge wire or ribbon, of between 150 and 600microns diameter or width compared to fine-wire bonding, which tends to be about 25microns.”

Boston goes on to say that SiC-based power module designs are aiming to switch up to 800VDC and handle up to 600A. He adds: “You need heavy gauge, but heavy gauge wire bonding of wide bandgap materials is a relatively new technology. More than ever before, there’s a need for collaboration and trust within the industry. Also, with keeping costs low such an imperative in the automotive sector, the use of advanced manufacturing tools likely to produce the best results is essential, particularly when some vehicle manufacturers are demanding zero defects and stipulating that reworks are not allowed.

CIL is an electronic solutions provider. It has the largest independent ‘chip and wire’ facility in the UK and its micro-electronics packaging facility is regarded as being at the forefront of the EV power revolution.

Boston concludes: “In addition to APC15@FutureBEV and GaNSiC, we’re the manufacturing partner on many other EV projects, plus we have many customers in the aerospace sector – active under initiatives like the More Electric Aircraft and the All-Electric Aircraft. “

The K&S Asterion is located in CIL’s BEV facility, and joins an automatic die bonder and high pressure Silver Sinter press (both of which are for the packaging of WBG materials) and a scanning acoustic microscope, used to detect voids. The Asterion will also be used in the manufacture of EV batteries, specifically for bonding between cells and busbars/plates.

Inseto is exclusive distributor for Kulicke and Soffa’s range of wire bonding and die bonding equipment & materials in the UK, Ireland and Nordic regions.

University of Warwick Turns to Inseto for a Probe Station to Evaluate ‘Next Generation’ Silicon Carbide Power Semiconductors

22nd September 2020

Andover, United Kingdom Inseto, a leading technical distributor of equipment and materials, has supplied the University of Warwick with a SemiProbe PS4L probe system for developing fabrication processes for next generation silicon-carbide (SiC) power semiconductor devices. The PS4L provides an accurate and repeatable means of mechanically interfacing fabricated prototype devices – as die or still on the wafer – with an analyser that can inject thousands of volts and measure hundreds of amps.

Silicon Carbide Probe Station for testing wafers and devices with high voltage and current
SemiProbe PS4L-SA – Silicon Carbide Wafer Probe Station at Warwick University

Dr Peter Gammon, Associate Professor (Reader) in SiC Power Electronics at the University of Warwick, comments: “We’re involved in a number of projects that are pushing the boundaries of silicon carbide power device research that will hopefully lead to the volume manufacture of device types that can currently only be fabricated in silicon. The PS4L is an invaluable tool in our endeavours as not only can it handle the high power from/to the analyser, but it is semi-automated, allowing us to collect a large amount of data from highly repeatable tests.”

Dr Gammon goes on say that most commercially available SiC power devices are unipolar structures, such as diodes and MOSFETs, which are well established and commercially available with high voltage ratings.

“We’re looking beyond these though, at bipolar devices that include IGBTs and thyristors because they will further enable highly efficient and ultra-high voltage applications, such as traction inverters and high voltage direct current in a low carbon society,” says Dr Gammon. “For example, silicon IGBTs are typically rated up to about 2,000V. As part of our work with the EPSRC Centre for Power Electronics, we are today producing silicon carbide IGBTs rated to 10,000V, with scope to go to 30,000V in the future.”

The PS4L is enabling Dr Gammon’s team to apply voltages of up to 10,000V and measure currents of up to 100A to confirm the performance and breakdown voltages of their devices. He says: “While we’re heading towards the production of IGBT and MOSFET switches, we’re able to do much of our work on simple structures such as diodes, in order to evaluate the repeatability of our fabrication processes.”

Following the supply and commissioning of the SemiProbe equipment, a software interface was written by Dr Gammon’s team to enable the PS4L and the high voltage parameter analyser to work together. “Both OEMs were incredibly supportive and gave us access to the source code of their respective products,” notes Dr Gammon.

The equipment is in use at the University of Warwick, one of only a few universities in the UK with SiC fabrication capabilities, and it has already enabled Dr Gammon’s team to capture data from larger test batches than would have otherwise been practical before. Also, there is more confidence in the data collected through automated processing, as it removes the discrepancies of manually obtained data, such as probe tip to pad alignment inconsistences and variations in contact force.

Dr Gammon, concludes: “Our new equipment represents a real game changer and the support Inseto provided has been exemplary throughout the entire process, from them understanding our requirements through to ensuring the PS4L was fit for purpose now and in the future.”

Inseto is exclusive distributor for SemiProbe in UK, Ireland and Northern Europe.
