They may still happen at your side.
Above issues puzzles most of us.
Intelligent Vayo NPI software makes manufacturing
more agile and smart!

Are you always willing to stay with those issues?
Quality defects, reliability issue, process
headache, business risk

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

• 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.
