Frequently Asked Questions


 

What do I need for a Fingerprint sensor bezel attach?


The key requirements for a fingerprint sensor bezel attach are a good and stable electrical coonection with the metal bezel that cures fast and in a low temperature while also having high adhesion to the metal.

Sounds demanding? Sure.That's why you might want to consider CE3103WLV with a fast thermal cure and high viscosity, ABP 2032S with low temperature cure and high adhesion or finally 2030SCR with lost stress and low temperature cure.

What is the lowest temperature cure adhesive?


Loctite 3220 is a non conductive adhesive designed to temperature cure down to 60°C. This multi purpose, one component epoxy typically fast cures in 5 to 10 min at 80°C. With 3 weeks work life at 30°C, it manages to have a high adhesion on FR4, Glass and many engineering plastics.

Electronics Assembly Materials

Henkel’s diverse portfolio of adhesive and sealant solutions includes advanced materials technologies to address today’s most demanding applications. From electrically conductive and non-conductive paste adhesives through to thermally conductive dielectric materials, our product line achieves maximum performance and cost-efficiency.

Our electrically conductive and non-conductive adhesives are ideal for withstanding the thermal and physical stresses of Defense, Automotive, Medical and Consumer Electronic assembly applications, while our spot cure technologies enable high-speed assembly for RFID tags and other printed electronic devices. Non-conductive paste systems in the Henkel portfolio include a series of one- and two-part room temperature, thermal and UV cure adhesives for the ultimate in flexibility and performance.

For manufacturers that require both adhesion and thermal dissipation functionality, our line of thermally conductive dielectric pastes are the most trusted and reliable materials on the market. Providing outstanding adhesion and thermal performance, Henkel offers both shimmed and nonshimmed formulations. For assembly specialists that require the utmost in accuracy, our shimmed adhesives contain engineered spacers for more precise bondline control.

Process flow of Assembly adhesives

Composition of Assembly adhesives

Adhesives are made from three parts. Resin, filler and hardener. Those components are what provide the adhesives with their end properties and can be mixed to formulate a huge amount of products. Following up, we'll list the main pros and cons for assembly adhesives. Just remember that one man's trash is another man's treasure, so just because something is not great for assembly, it doesn't make it bad for all the other application types out there.
