What is the role of Design For Testability - Vayoinfo

Description:

Design for Testability (DFT) is composed of two very important words. "Testability" is a condition of a routine that makes it possible, easy, and cost-effective to test and identify the routine (unit) under test (UUT). There is a wide approval that like a character must be part of gadgets ICs, boards and systems, too. Visit for Design For Testability @ – PowerPoint PPT presentation

Title: What is the role of Design For Testability - Vayoinfo


1
Design for Testability
Towards Industry 4.0 IoT
2
Change from NPI
Past
Yesterday
Today
Vayo customer solved this issue. Ex.
Intel/Venture/SurfaceArt/Bosch
They may still happen at your side.
Above issues puzzles most of us.
Intelligent Vayo NPI software makes manufacturing
more agile and smart!
3
Are you always willing to stay with those issues?
Quality defects, reliability issue, process
headache, business risk

Design

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,

2
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.

Core product Intelligent NPI software for PCBA
  • Reduce design mfg cycle 30-70
  • Reduce quality defects 30
  • Increase reliability 30
  • Increase design and mfg efficiency 40
  • Reduce design and mfg cost 20
