Company Advantages1. For Rocket PCB , excellent design should be a perfect combination of appearance and performance. It is subjected to extreme heat and soldered into place
2. Our high quality motherboard pcb is targeted at high-end market. It is specifically designed to lessen the chances of shorts and wiring issues
3. This product is anti-rust and anti-corrosion. Its metal finish is treated with a natural anodic layer formed in the air, hence, it will not get rust or corroded easily. It makes the interconnections less bulky
4. The product is excellent in heat dissipation. Usually constructed from copper or aluminum which has a very high thermal conductivity, the product also features a high rate of heat transfer. It reduces the need for interconnecting wiring
5. The product has excellent mechanical strength and loading capacity. It is treated with die-casting under high-temperature and high-pressure conditions, therefore its structure is firm and tough. All the components within this product are fixed using solder flux
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.
