An interesting exercise: go to Google Patents and search for the term “Thinky”. The results demonstrate the enormous range of original technology breakthroughs which have depended on the ability of Thinky mixers to mix challenging liquids, pastes and powders in nanotechnology, batteries, electronics, pharmaceuticals, and many more. Can we help you with your R&D?

Adhesive bonding of power modules can often be an alternative to usual joining techniques. Epoxy-based adhesives can generally produce high-strength and stable connections. Whether this also applies to the high requirements in power circuits was the subject of a research project recently performed by the IMTEK Department of Microsystems Engineering and the IESY Institute of […]

We are witnessing the widespread adoption of contactless cards for payments, rather than the hitherto main applications of access control and ID. The key to the reliability and longevity of these dual interface smart cards is the effectiveness of the electrical connection between contact chip and RFID antenna. One solution is Polytec PT’s PU 1000, […]

You can buy two (or more) part adhesives which have been pre-measured into the correct proportions, mixed and degassed, filled into a dispensing syringe or cartridge, and then frozen to stop the cure. The adhesive is shipped from the factory to you in an insulated box also containing ice. Upon delivery, you store the adhesive […]

We have issued two new guides which offer an introduction to the Electrically Conductive Adhesives and Thermally Conductive Adhesives produced by Polytec PT. Each guide gives a descriptive overview of the technology involved and related product applications in industries such as microelectronics, electrical engineering, power engineering and general energy. New, next generation technologies are introduced. Conventional […]

Polytec PU 1000 is a single part adhesive which cures quickly at room temperature to a flexible, electrically conductive polymer. It can replace traditional epoxies which are typically rigid and require high temperature cure, giving production efficiencies and enabling new applications where pliability and conductivity is important. Polytec PU 1000 addresses applications in die attach, bonding of […]

The preeflow® eco-DUO600 offers precision metering and mixing of two component materials with mixing ratios adjustable up to 5:1. It is designed for use with two component materials such as silver loaded conductive epoxies, silicones or polyurethanes which may be dispensed in small quantities for either dots or beads. We see applications in microelectronics, medical optics, […]

We see many requirements for an electrically conductive bond formed with an adhesive. They vary from the micro (flip chips onto pcb’s, die-attach) to macro (wires onto sensors), and the range of projects is substantial. Often, our customers would like to use the adhesive in place of solder. The reasons include temperature restrictions, geometry, process […]

Back in May we launched the CircuitWorks range of syringed packaged conductive greases to help improve the applications for our customers with electrical and thermal conductivity requirements. We offer three types of conductive grease: Silver Conductive Grease Boron Nitride Heat Sink Grease Silicone Free Heat Sink Grease The Silicone Free Compounds will not harden or […]

The CircuitWorks® range of conductive ink pens are now in stock. They help engineers and technicians in electronic manufacturing and repair sectors. They instantly create silver or nickel conductive tracks on rigid or flexible circuit boards in the prototyping, rework and repair of boards (or flex circuits) where they enable linking of components, repair of […]

The CircuitWorks range of pcb rework, repair and prototyping materials, which come in very convenient and easy to use formats, are now readily available from us ex stock. The easy-to-use valved pen and syringe delivery systems enable developers, technicians, installers and servicing engineers to carry out small area electronics repair. This includes cleaning, protection, bonding […]

Polytec EC 275 has innovative specialist fillers which deliver excellent electrical conductivity (1×10-3 – 7.5×10-4 ohm-cm) within a low cost, two component formulation for applications in electronics, micro-electronics, opto-electronics, hybrids and sensor technology. Electrically conductive adhesives are widely used in the electronics […]

Polytec PU 1000 is an electrically conductive, polyurethane adhesive which addresses applications in die attach, bonding of components in hybrid circuit applications and surface mount technology (SMT); areas where silver filled electrically conductive adhesives have been used for many decades. Usually such adhesives are epoxy-based, and are two-component or premixed and frozen single-component systems – […]

For those of you with bonding applications at high operating temperatures, we have some news!  Polytec PT Polyimide Adhesives provide excellent thermal resistance which is superior to any other organic adhesive. These modified polyimides are single component, solvent-based adhesives and coatings which are useful in the temperature range from 240°C to 500°C. They are available […]
