About our product

Rocket PCB provides gold finger PCB, long-short gold finger PCB, staged gold finger PCB fabrication. Gold finger PCB advocate higher necessities for the producing technology. If you do not have enough expertise, it's straightforward to cause unhealthy issues like darkening, whitening, contamination, lateral erosion, scratch and alternative issues.

Rocket PCB has intensive expertise during this field and has accumulated a few years of process expertise. Through method optimisation, improve film alignment, liquid concentration management, plating parameters and alternativelinks of optimisation. Our gold finger quality totally meets client necessities, won client appreciation.

Why design gold finger


A unique PCBA needs to be interconnected with the motherboard, however it additionally must be simplyreplaced. Style a gold finger connected to the socket, just like the connection between the facility plug and socket. as a result of gold has smart conductivity, inertia is powerful, it will make sure the semiconductive impact whereasnot oxidizing, at identical time, it also can guarantee adequate physical phenomenon when frequent insertion as a result of gold is wear-resistant.

Generally speaking, the golden finger implies that these fingers square measure plated with 5-30u” hard gold. hard gold has higher wear resistance and might be secured 20,000 times insertion while not affecting the quality, it should be over 5u” thick. However, the process technology of hard gold is comparatively complicated, and also the high thickness of gold consumes a lot of gold salt, that directly ends up in high price. In fact, several PCBs don't need frequent insertion, don't ought to do thick gold, or maybe don't do hard gold, directly do immersion gold replacement (soft gold, the gold thickness is usually 1-3 u”). It will effectively scale back the purchase price of PCB.


Some common applications of golden fingers are:

  • ◪   Provide interconnection points for transmitting network data.

  • ◪   Where a sub-board or dedicated adapter is attached

  • ◪   Connect external components to the prototype PCB

  • Use as an audio adapter

Elctroplate process


ENIG: ENIG is more cost-effective and easier to solder than the electric gold plating. But its soft and thin (usually 2-5u ")composition makes the ENIG unsuitable for achieving the abrasion effect caused by the circuit board insertion and removal.
Electroplated Hard gold: This gold is solid (hard) and thick (usually 30u "), so it is more ideal for achieving the abrasive effects caused by constant PCB usage. 


There are many meticulous steps involved in the process of plating gold fingers. To ensure that all of these fingers and slots fit, each PCB must pass a series of inspections and defect tests.   



TYPES OF GOLD FINGER


professional equal length highly-rated finger for wholesale-3


Standard gold finger:Gold fingers are of equal length.
Staged gold finger PCB :The etching pattern of the golden finger position needs to be realized by multiple film pasting, exposure and solder masking. The position and pattern need to be strictly and accurately controlled.
Long-short gold finger PCB:Its process is similar to the staged gold finger, which requires multiple exposure and electroplating to obtain the graphics of the long- short gold finger and  requires the following design rules: plated holes, SMD and pads should not be placed within 1.0 millimeters of the gold finger; plated pads cannot exceed 40 millimeters in length.


As more and more technologies rely on gold fingers, it is vital that we have them plated and tested to meet the highest standard and to ensure the highest performance. Rocket PCB provides the PCB with the highest quality for customers from different industries with our extensive experience.
