We have problems with achiveing a void free soldered joint when we seal different kind of packages (QFP,LCC and PGA) We think the problem partly is due to outgasing from the die-adhesive (silver-glass) Does anybody have any reccomendations what to d

Set Up Guy, I am not sure if the COB you are refering to means Circuit on Board . If yes, this process also include SMT . Package is a combination of some passive components and bare die. Passives are normally attached thru SMT using solder te

Thank you ur reply Dave. Let me explain our COB workflow: 1. unpack PCB (FR4,LPI,HASL)(the thickness of gold and nickel we can't be find)(No SMT before) 2. clean the pcb by rubber 3. blow the pcb by di-ionic gun 4. attach die by adhesive gel 5. cure
