When the process of PCB Card reverse engineering has been done, it has been approved that even if the schematic is correct, the electronic device reliability will be doubted is not well. For example, if the two parallel lines very close to each other, will cause the delay of signal wave transmission, and generate the reflect noise at the end of transmitting line;

PCB(인쇄 회로 기판) 리버스 엔지니어링은 원래 설계 문서나 회로도에 액세스하지 않고 PCB의 설계, 레이아웃 및 기능을 분석하고 이해하는 프로세스를 의미합니다. 이 실습에는 회로도나 설계 레이아웃을 다시 만들기 위해 기존 PCB를 분석하여 구성 요소, 연결 및 기능에 대한 정보를 추출하는 작업이 포함됩니다.

Interference caused by inappropriate consideration of power supply, grounding will degrade the performance of product. As a result of that, when reverse engineering PCB card, proper PCB reverse engineering measure must be taken to ensure all the switch power supply can have four current reflow:

1> Power supply switch alternative reflow;

2> Output rectification reflow;

3> Input signal source current reflow;

4> Output overload current reflow;

Input reflow charge the capacitor on the PCB card through direct current resemble when reverse engineering PCB card, wave filtering capacitor play the role of wide band energy storage functions. Similarly, output wave filtering capacitor can be used to store the high frequency energy comes from the rectifier, and eliminate the DC energy of output overload reflow.

PCB (Printed Circuit Board) reverse engineering verwijst naar het proces van het ontleden en begrijpen van het ontwerp, de lay-out en de functionaliteit van een PCB zonder toegang tot de originele ontwerpdocumenten of schema's. Deze praktijk omvat het analyseren van een bestaande PCB om informatie over de componenten, verbindingen en functies ervan te extraheren om de schematische of ontwerplay-out opnieuw te creëren.

Consequently, output and input wave filtering capacitor wire connection point is critical, if the output/input current reflow and power supply switch fail to connect with connecting point of capacitor, alternative energy can radiate to environment through output or input wave filtering capacitor.
