An Article to Take You to Understand the PCB Gold Finger

图片
  What is Gold Finger: It is commonly found in computer hardware, such as between memory modules and memory slots, graphics cards and graphics card slots, etc.  Because it is composed of multiple golden conductive contact pieces with gold-plated surfaces, and the conductive contact pieces are arranged in a finger shape, so it's called "Gold finger".   The Role of PCB Gold Fingers: Let's take the memory module as an example.  When the gold finger is inserted into the card slot, the memory module and the motherboard can be interconnected and transmit signals, and it is also easy to disassemble and replace.  For this kind of gold finger board that is often plugged and unplugged, the electroplating nickel gold technology is usually used. It not only has good wear resistance, but also has excellent electrical conductivity and oxidation resistance. For gold finger boards that do not require high wear resistance, you can choose the entire board immersion gold technolog...

The Importance of Line Width and Line Space in PCB

图片
          Do you know why the importance of line width and line space in PCB cannot be ignored?  Because they will directly affect the performance, reliability, etc. of the circuit board. The following will take you to understand the importance of line width and line space in PCB:   1. Electrical   P erformance Line width and line spac e can   affect the electrical performance of the circuit board.   Line width determines the resistance of the wire, and line space affects signal crosstalk. The correct selection of line width and line space can ensures the signal integrity and stability of the circuit board.     2.  Power  T ransfer and  T hermal  M anagement Line width selection is critical for power transfer and thermal management.   Wider wires may be able to handle higher currents, but will also increase power losses. The choice of line width and line space also affects the distribution of heat ...
