Golden finger circuit board

The utility model provides a golden finger circuit board, includes the base plate and locates a plurality of golden finger piece on the base plate, the golden finger piece reaches with two including the tip that is located the length direction both ends the both sides limit that the tip is do not connected, the golden finger piece the side is equipped with the breach. Above -mentioned golden finger circuit board sets up the breach through the side at the golden finger piece and can flow in the breach owing to soldering tin, during the welding, has increased the area of contact that golden finger piece and printed circuit board went up soldering tin to effectively avoid rosin joint, vacation the unfavorable condition such as to weld, improved the joint strength of golden finger circuit board with printed circuit board, and breach adsorbable soldering tin still, owing to the reason of adhesive force, soldering tin is difficult to the diffusion to avoided piling the short circuit that tin caused, improved the welding yield.
