Reverse Engineering PRINTED CIRCUIT BOARD about EMC Depressing

After Reverse Engineering PRINTED CIRCUIT BOARD, EMC issues must be taken into consideration, because it will become quite difficult in the process of PRINTED CIRCUIT BOARD Layout refers to the distributed capacitors and the way to grounding. PRINTED CIRCUIT BOARD Layout after reverse engineering PRINTED CIRCUIT BOARD need to consider a lot of things as we all know, the only thing is under different circustumce different things will be considered.

Connecting and split the ground: grounding is one of the most important methods to depress the electromagnetic interference and improve the electronic device EMC performance. Grounding the circuit track after PRINTED CIRCUIT BOARD Reverse Engineering can not only increase the PRINTED CIRCUIT BOARD ability to resist the electromagnetic interference, but also decrease the EMI radiation towards the outside world.

Grounding Concept when Reverse Engineering PRINTED CIRCUIT BOARD

There are two different concepts in the meaning of PRINTED CIRCUIT BOARD grounding when reverse engineering, one is the earth in the aspect of safety, others are systematic basic ground in view of signals. Grounding means the low resistance value electrical connection among the different electrical levels. Grounding the earth means take the electrical level of earth as standard.

Grounding the PRINTED CIRCUIT BOARD level to the earth is bases upon the below aspects after PRINTED CIRCUIT BOARD Reverse Engineering

1, improve the electronic circuit system working stability;

2, electrical static discharge;

3, provide the security insurance to the PRINTED CIRCUIT BOARD reverse engineering worker;

For the purpose of Reverse engineering PRINTED CIRCUIT BOARD:

1, security consideration and grounding protection;

2, provide a stable zero electrical level reference point for the signal voltage;

3, grounding shielding when reverse engineering PRINTED CIRCUIT BOARD;

There are three different basic ways to grounding which include the single point grounding, multiple point grounding and floating grounding;
