Epoxy Die Attach

Our epoxy die attach service is the most common die attach method requested by our customers. We offer both conductive epoxy die attach and non-conductive epoxy die attach. We are capable of automated epoxy writing, which provides excellent under-die epoxy coverage. Our automatic die attach equipment can pick from Waffle-pak, Gelpak, or wafers up to 200mm in diameter. Placement accuracy down to +/- 12 microns is available and we can handle die thicknesses of as little as 50 microns.

Vacuum Solder Reflow

Solder / Eutectic Die Attach

Our solder die attach process is compatible with solder paste or solder preforms. We offer Vacuum reflow or Belt furnace reflow. Our Vacuum reflow utilizes a Solid State Equipment Corp model SST 1200 vacuum reflow oven for near void free die attach. Solder reflow temperatures up to 400C are supported. Common solder preforms are 90/10 Lead/Tin and 80/20 Gold/Tin. Our eutectic die attach is available for Au/Sn or Au/Si applications.
