2. It happens around us whatever you notice or not On year 2013, Hitachi elevator free fall due to defected board in China, a lady was injured in this event. On year 2013, GM recall 380,000 vehicles due to defected engine control board. Due to abnormal behavior of PCBA, Taiwan high speed train lost power on year 2013. Major reason of AirAsia QZ8501 crash on year 2014 is a cracked solder joint on PCBA. On year 2013, Chrysler recalled >470,000 vehicles due to defected board. On year 2014, Mitsubishi recall 115,000 cars due to defect board of light switch.

24. Sample DFx issue: material not match PAD design Impact • Stop production, waste product line resource • Delay shipment & go-to- market Package not match Package not match Package not match Missing via, small copper size

25. Sample DFx issue: components too close Impact: Require high precise equipment • Risk of assembly conflict • Difficult to rework •

26. Sample DFx issue: Via distance to pad Impact: More via on boards, it shall be more easy to bring short, bridge, and insufficient solder issues. Good design

27. Sample DFx issue: annual ring design Annual ring too small, even missing Via offset to pad Impact: Easy to cause weak structure; lead to crack/ broke & malfunction in severe usage conditions.

28. Sample DFx issue: risk for via under component Impact: May cause bridge/short when PCBA goes through wave process.

29. Sample DFx issue: Via under BGA pad Impact: via in BGA pad, it might lead to weak solder joint strength because of void. It shall impact product reliability.

30. Sample DFx issue: BGA pad design Solder mask defined pad, it shall easily cause the root of solder joint crack especially in frequently shock environment.

31. Sample DFx issue: no thermal consideration Good design Poor design Poor design Impact: It might cause tombstone if there is no thermal consideration. Or it might cause insufficient solder for PTH parts, and then impact solder joint strength and product reliability.

32. Sample DFx issue: PTH part to mask strip Poor design Impact: PTH part approach mask strip too near, easily cause solder issue like short.

33. Sample DFx issue: poor test point design TP size impact contact of probe, then impact faults reject rate of test.

34. Sample DFx issue: poor silkscreen design No polarity mark Cross of part reference name Impact • Wrong polarity during assembly • Replace with wrong material during rework

35. Sample DFx issue: no local fiducial for fine-pitch parts Impact Brings offset risk during assembly Good design

36. Sample DFx issue: Orientation of part pass through oven Poor design Good design Impact: Part placement orientation shall be consistent with wave process, otherwise it may casue bridge.

37. Sample DFx issue: BOM content error DFM Expert perform intelligent check of BOM content, report any quantity mismatch error. Impact: Component mismatch may leads material shortage for the work order, which leads to production stop, waste equipment resource; Or cause excessive material purchasing and extra inventory.

38. Sample DFx issue: Alternative part analysis DFM Expert compare dimension between alternative part with primary part, and alter upon big size difference. Impact Big size difference between alternative part with primary part may cause assembly problem, solder joint defect or poor reliability.
