Why replace solders with conductive adhesives?


Frequently Asked Questions

Solders provide a metallurgical joint that has good electrical and thermal conductivity. Solders can be tolerant of component placement or process variations. They are re-workable and the soldering process is easy to automate.

However, solders require relatively high temperature processing, typically around 240° to 270°C compared with around 150°C for adhesives, and usually require metallised surfaces to 'wet' onto and form joints. Also, the lead used in many traditional solders is toxic and elimination of its use is required by legislation in many countries.

The structural integrity of solder joints can be detrimentally affected by fatigue and creep. Thermally-induced mechanical fatigue and creep relaxation caused, in particular, by temperature cycling can lead to the initiation and growth of cracks and consequent joint failure.
