Company Advantages1. The design of Rocket PCB expresses attraction and deep expression to the customers. It is the perfect choice for manufacturers of electronic components, instruments, and equipment
2. Rocket PCB Solution Ltd. hopes to meet all its economic goals within years by employing advanced technologies. Its signal paths are well organized and exposed quite well
3. The product is safe enough. It is manufactured in line with UL safety standards, thus the danger of electric leakage is totally eliminated. The product features low electric currents and radiation emission
4. The product is characterized by low heat generation. During its operation, exothermic reactions between the chemicals used and Joule heating will not increase its temperature. Its connections made automatically through copper tracks
5. The product is resistant to aging. The organic rubber materials used are tested at ambient (73°F), and most of these will take a permanent set at elevated temperatures. It improves the wiring density and reduces the spacing of components
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
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.

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.
