Rocket PCB supports gold-plated finger PCB, immersion gold gold finger PCB, hard golden finger PCB, flash gold gold finger PCB, long-short gold finger PCB, staged gold finger (graded golden finger) PCB production. Gold-plated fingers put forward higher requirements for the production process. If the experience is insufficient, it is easy to cause bad problems such as blackening, whitening, pollution, side corrosion, scratches, size discrepancy and so on.

Rocket PCB has rich experience in this field, and has accumulated many years of production experience. Through process improvement, film optimization, liquor adjustment, plating parameters and other links of optimization, it has completely realized zero defect, which is highly appreciated by customers.

What is a gold finger


Gold finger is the generic name of the gold-plated connector that runs on the edge of the PCB prototype. Because they are golden, long and thin, they are similar to fingers, so we call it gold finger.

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

Conventional gold finger:Gold finger is 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 golden 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.
