 New Water Circulation and Filtration system was installed on Film Strip line which removes most film particles so Nozzles does
not get clogged on Ringe water.
 Vibration System was installed on 5 tanks in plating line for better plating on Micro vias holes and for elimination of pitted
plating and mouse bites on surface/traces.
 New software was purchased for chemical analysis with SPC capabilities and various reporting capabilities.
 For better adhesion of Solder Mask on ENIG job, new process was installed after Aluminum Oxide and prior to Ringe/Dryer.
This process was tested and proven prior to final permanent installation.
 New Cu Bus Bar were purchased to replace all old one in plating Tanks. With total investment over $10,000
