PCB Power Integrity ; PI
Power Integrity is the foundation function on PCBs, and why we say?
Power DC is basic which can check stable and ready work for IC chipset.
Power AC is the rule for AC noise ripple in designed Spec.
Caps is important on AC rule, optimized caps can be reduce COST < COST DOWN >and under AC designed Spec.
電源品質對於PCB來說是基本的功能確認，為何我們會這樣說呢?
電源DC是確認IC晶片組是否能穩定且正確工作的重要依據。
電源AC則是確認雜波是否在設定規範內。
電容對於電源品質是非常重要的，我們可以優化/減少電容來降低成本，又不失於規範的要求。
