Benefits of Design for Testability – Vayoinfo

This has led to the strategies and technologies of design for testability (DFT). This book is a comprehensive guide to new DFT techniques that will show the readers how to design a testability and quality product, drive down test cost, improve product high quality and yield, and speed up time-to-market and time-to-volume.<br>

  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 1 4 • No thermal consideration, small annual ring small, silkscreen error, Silkscreen incomplete, … • >30% PCB design comes with problem. • Wrong polarity, location offset, inline fine-tune, … • Lower test coverage, lower utilization, … 2 5 Manufacturing NPI cycle • Short, open, tombstone, cold sold, Void, … • >60% defects could be found prior to build • Frequent prototyping, high cost • Long cycle, impact time to market, … 3 6 Post sales Process design • Difficult to transfer knowledge • No effective tool to continually improve process capability • … • sold joint crack, sold joint peeloff, … • Repair rate for consumer product: 5%~37% in initials 3 years IPC research: 80% defects could be found and resolve during NPI stage.

  4. 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% + Intelligent DFx analysis DFM Expert & DRC+ Process Eng., Industry Eng. Debug tech, others… PCB layout Eng., process Eng. NPI Eng. Testing Eng. SMT programmer Document Expert SMT Expert/ Accelerator Other NPI sw Test Expert Fast placement programming, support Fuji, Panasonic, ASM, Juki, Yamaha… Board troubleshooting, Gerber conversion, assembly drawing, NPI team collaboration DFT/Testability, ICT/FP/AXI/AOI programming Work instruction document preparation * NPI：New Product Introduction

  5. Company introduction • Founded on Jan of 2005, headquarter in China/Shanghai; • Dedicates to intelligent NPI software to accelerate design to manufacturing; • Fully in-house development, owns copyrights and patents; • Product installed >20 countries and regions worldwide; • Strategy partnership with equipment and EDA provider: Keysight/ViTrox/TRI/Fuji/Panasonic/Altium… >10 years dedication on NPI technology brings up the world-class product.
