Considerations for Gold Finger Bevel Design
Considerations for Gold Finger Bevel Design
In our daily lives, we often come across products with a row of contacts on the PCB edge used for connections, which are known as PCB gold fingers. They are also referred to as "edge connectors", typically serving as the external connection interface for a PCB board when inserted into a slot.
Technical Guidance
So, what should you keep in mind when designing PCBs with gold fingers?
Excessive beveling of PCB gold fingers can result in the fingers not making proper contact with the mating equipment during assembly, leading to poor connectivity and potential usage issues.
Therefore, during the design phase, it's crucial to ensure that the length, width, position, bevel angle, and depth requirements of the gold fingers match the length of the fingers themselves. Be careful not to make the fingers too short or the bevel too thin, rendering them unusable. Additionally, make sure there is a sufficient safety margin between the gold fingers' edge and the board edge. In cases where this margin is insufficient, our engineering team will optimize the design.
Design Optimation
Here are the details:
The length and width dimensions after beveling a single board or a panel should not be less than 50mm.
