Gold Finger PCB
If you look at your laptop memory card, you will see it is PCB that has gold-plated long and narrow connectors on the edges, they look like our fingers, so this kind of PCB we call it gold finger PCB.
Your Premier Gold Finger PCB Supplier
Venture has more than 10 years gold finger PCB (printed circuit board) manufacturing experience, by using the latest materials and technology, we have helped thousands of electronic engineers’ gold finger PCB products into the market, from prototype to pilot run until mass production.
From single layer board to 32 layer board, from flex PCB to rigid flex PCB, Venture can offer the complete gold finger PCB solution. Our two production plants are fully equipped with state-of-the-art machines that can support you from prototype to volume production. Pls, check our details gold finger PCB capabilities.
Your Best Gold Finger PCB Manufacturer In China
Gold Finger PCB are plated by flash gold(one of the hardest gold available) instead of soft gold, and the hard gold thickness has to be from 3u“ to 50u“, because the “ fingers(connectors) ” are designed to handle at least 1000 cycles of “plug in and out(wear and tear)”without repair.
Nowadays, the biggest applications for gold fingers PCB are still computer memory card and graphics card, and these two products are mostly produced in Taiwanese PCB manufacturers with huge order volume.

Gold finger recognition method for PCB circuit board
Features: No character frame and label.
Conventional for solder resist layer opening window, most profiles have grooves.
Gold finger part of the projection of the board edge, or near the edge of the board. Some boards have gold fingers on both ends, normal gold fingers on both sides, some pcb boards have only single-sided gold fingers, some gold fingers single wider and other characteristics.
PCB gold finger beveled edge
The beveled corners of Goldfinger PCBs help turn square edges into slopes. Most of the time, the edges of Goldfinger PCBs are always beveled.
The beveling process of Goldfinger starts after the solder resist layer and before the surface finish. This process is critical because it makes insertion easier and faster. Without chamfering, insertion would be slower and more difficult.
Typically, gold finger PCBs are beveled at an angle of 45 or 30 degrees. However, our engineers will bevel the Goldfinger PCB according to the customer’s needs. The bevel angle of the gold finger is also influenced by the size of the PCB.
