CoS is a new development of ASM AMICRA especially designed to conquer all Chip on Submount applications. This machine is capable to perform multi-die bonding of up to +/- 1.5µm@3s placement accuracy on singulated submounts by using eutectic bonding method, realized either with a ceramic pulse heater or localized non-contact laser heating with a cycle time up to 6s.
Beside this bonding methods the CoS can also be equipped with epoxy stamping suitable for solder paste or epoxy.
The core is the bonding table equipped with two bonding chucks. While from the chip side the machine uses ASM AMICRA dynamic alignment method to pick chips and bond with high precision to a submount, the submount side loads new submount and unloads finished CoS, in parallel it can perform stamping or preform handling.
