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
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.
