We are looking at implimenting a bar code system for a SMT production line. To start we are looking at label printer/applicators. Are there any other companies that we should consider besides Zebra and Imtec?? Thanks for your input. John

Conductive adhesive

Electronics Forum | Wed Aug 19 06:40:06 EDT 1998 | G Thomas

Require a conductive adhesive - either isotropic or anisotrpic - which can be used for 100micron oitch devices. Must be resistant to solvents such as MEK and acetone. Cure below 150C, with possible potential for rework of the conections.
