Equipment programming

• No thermal consideration, small annual ring
  small, silkscreen error, Silkscreen incomplete,
• gt30 PCB design comes with problem.

• Wrong polarity, location offset, inline
  fine-tune,
• Lower test coverage, lower utilization,

Manufacturing
NPI cycle
5

• Short, open, tombstone, cold sold, Void,
• gt60 defects could be found prior to build

• Frequent prototyping, high cost
• Long cycle, impact time to market,

Post sales
Process design

• sold joint crack, sold joint peeloff,
• Repair rate for consumer product 537 in
  initials 3 years

• Difficult to transfer knowledge
• No effective tool to continually improve process
  capability

IPC research 80 defects could be found and
resolve during NPI stage.
