Mechanism
1. Board dimension and mechanism check. Ok Fail
板子尺寸﹔機構檢查
2. Stack checking. (Top, VCC, GND and Bottom layer,…) Ok Fail
疊層檢查
Placement
1.To keep enough space between part's outline and board's edge(50mil/200mil) Ok Fail
零件到outline的距離(50mil/200mil)
2.The connectors and slots location match with mechanical DWG?(Notice pin 1 direction) Ok Fail
connectors和SLOT零件要和機構對齊﹔pin也須要對齊
3. High limitation check. (CPU, PCI SLOT,I/O connectorsand AGP SLOT,...） Ok Fail
Check限高區
4.The part's direction and polarity keep same way?(two directions no more than ) Ok Fail
有極性的零件(電容/二極體)要保持方向一致。(不多於兩個方向)
5. The jumpers/connector too close ? Pls reserve a room for slot inserted and adjustment? Ok Fail
跳線/connector是否太近?預留slot的插拔及調節空間
6.The damping resistor close to start of source, the termination resistor close to end of loading? Ok Fail
damping電阻擺放在起點端﹔termination電阻擺放在未端﹔
7. The decoupling capacitor close to power pin of active parts. Ok Fail
by PASS電容要接近Power出線端
