The use of thinner components and thinner multi-up panel PCBs (≤ 40 mils) has led to PCB warpage issues in SMT assembly process, which in turn impacts the PCB assembly yield. Study needs to be done in order to gain a better understanding on the key PCB manufacturing factors that impact PCB warpage. This project conducted experiment with a 10-layer PCB test vehicle design using two different PCB suppliers. The experimental factors included PCB post processing (bake & no bake PCB), panel locations (corner & center), PCB thicknesses (0.8 mm & 0.6 mm), Material (Mid Tg & High Tg), and PCB processing (lamination process at PCB vendor A vs. B). The PCB warpage was evaluated using high temperature measurement warpage metrology to evaluate the ball grid arrays (BGA) and panel area PCB coplanarity. Data analysis results and findings will be reported at the webinar.
