Grace的進修雜記:)

This past summer I knew how to trouble shooting a circuit board.

Recently we had some issues with a circuit board from a power supply.

Unfortunely, we found that a few capacitors needed to be replaced, but we don’t have schematic or other information in hand.

At least it looks like they are still readable which is helpful.

When some brown or rust-coloced electrolyte leakage were fround from a few capacitors, the first step is to replace them to bring the circuit board back fully functional.

We also keep few similar ciircuit boards in hand in case something happens in the future.

暑假期間修復機台的時候發現電源供應器失效，拆下電路板後發現失效的主要原因基本上都是電容漏液。

樂觀上來說該覺得慶幸的一點：雖然機台老舊但電容器上的號碼還是可以清楚地看見，所以簡單的替換後希望機台可以恢復作動！
