Professional gold column highly-rated fingers for wholesale

Company Advantages
1. gold column is produced by high-quality material exported from abroad. Its compact design takes less space in a piece of application equipment
2. The product helps create a harmonious family atmosphere and a strong sense of breath of life. People can interact with their families during cooking. Its components are always soldered in, which contributes to durability
3. The product is able to withstand the most rigorous industrial conditions. Made from new materials, like improved steel alloys and other composites, it is durable enough. Its assembly process is conducted by a computer, leaving very little room for error
4. The product stands out for excellent mechanical performance. It operates in a stable manner even in humid or high temperature environment. It makes the interconnections less bulky
5. This product is easy to care for, to a certain degree anti-wrinkle. And it has the added benefit of getting softer after each wash. It reduces the need for interconnecting wiring

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.   

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.
