Classification and Characteristics of PCB Gold Fingers
Golden fingers are one of the surface processes of PCB. PCB gold fingers can be divided into ordinary PCB gold fingers (flat fingers), segmented gold fingers (discontinuous gold fingers), and unequal length gold fingers (curved gold fingers). The specific PCB gold fingers are as follows:
1. Ordinary gold finger
Neatly arranged at the edge of the PCB, with the same length and width as the rectangular solder pads.
2. Segmented Golden Fingers
Rectangular solder pads have different lengths at the edges of the PCB and the front end has already been disconnected.
3. Different lengths of golden fingers
Rectangular pads are located at the edges of the PCB, but with different lengths.
Perhaps you have this question: "Why do PCBs need to have different lengths of gold fingers?" Let's take a look at the reasons below.
Ensure that the PCB can be properly inserted into the corresponding slot in the device.
Realize reliable electrical connections between PCB and other device components.
Try to minimize the resistance on the signal path to reduce noise and interference that may cause errors or malfunctions during operation.
Allow PCB to be securely connected to other PCBs within the same system, thereby achieving efficient data transmission between different boards when necessary.
Compared to copper or aluminum contacts used in certain PCB connectors, gold has superior corrosion resistance, thereby improving the durability of PCB connections.
