What is Gold Finger?

On the computer memory and graphics card, we can see a row of golden conductive contacts, which are called "golden fingers". In the PCB design and manufacturing industry, gold finger (or edge connector) is used as the outlet of circuit board external connection network through connector plug-in.

PCB Gold Finger Type

1. Regular golden fingers (flush fingers)
Rectangular pads of the same length and width shall be arranged orderly at the edge of the plate. For example network cards, video cards, etc.
2. Long and short gold fingers (i.e. uneven gold fingers)
A rectangular pad with different length at the edge of the plate. For example memory, U disk, card reader, etc.
3. Segmented golden fingers (interrupted golden fingers)
A rectangular pad with different length at the plate edge and the front section is disconnected

Surface Treatment of Gold Finger PCB

1. Nickel gold plating: the thickness can be up to 3-50u ". Due to its superior conductivity, oxidation resistance and wear resistance, it is widely used in the gold finger PCB which needs to be plugged in and out frequently or the PCB which needs to be subject to mechanical friction frequently. However, because of the high cost of gold plating, it is only used in the local gold plating treatment such as gold finger.

2. Immersion Gold: the thickness is 1U in general and 3U in maximum. Because of its excellent conductivity, flatness, and solderability, it is widely used in high-precision PCB boards designed by key position, binding IC, BGA, etc. For the gold finger PCB with low wear resistance requirements, the whole board immersion gold process can also be selected, and the cost of the immersion gold process is much lower than that of the electric gold process. The color of the immersion gold process is golden yellow.

Detail Processing of Gold Finger in PCB

1) to increase the wear resistance of gold fingers, hard gold plating is usually required.

2) the golden finger needs to be chamfered, usually 45 °, other angles such as 20 °, 30 °, etc. If there is no chamfer in the design, there is a problem; 45 ° chamfer in PCB is as shown in the following figure:

Golden fingers need chamfering

3) The gold finger needs to be Solder Mask and windowed, and the pin does not need PCB SMT stencil.

4) The minimum distance between the immersion tin and immersion silver solder pad and the tip of the finger is 14mil. It is suggested that the distance between the solder pad and the finger position should be more than 1mm, including through-hole solder pad;

5) Do not lay copper on the surface of gold fingers;

6) All layers of the inner layer of the gold finger need to be cut copper, which is usually 3mm wide; it can be used for half finger cutting and the whole finger cutting.

Is the "gold" of Gold Finger Gold?

First, we need to understand two concepts: soft gold and hard gold. Soft gold, generally gold. Hard gold, usually a compound of hard gold.

The main function of the gold finger is connection, so it must have good conductivity, wear resistance, oxidation resistance and corrosion resistance.

Due to the soft texture of pure gold (gold), gold fingers generally do not use gold, but only electroplate a layer of "hard gold (gold compound)" on it, which can not only obtain good conductivity of gold but also make it have wear resistance and oxidation resistance.

Has PCB ever used "soft gold"? The answer, of course, is used, such as the contact surface of some mobile phone buttons, aluminum wire on the cob (chip on board), etc. The soft gold is usually deposited on the circuit board by electroplating. Its thickness control is more elastic.

Tip: no matter whether the PCB is plated with soft gold or hard gold, the amount will not be too much. Please don't dismantle the electronic instrument for "taking gold"!

What is PCB Gold Finger Window

What is the PCB window? Generally speaking, the wires on PCB are covered with oil to prevent short circuits. The window opening is to remove the paint layer on the wires so that the wires are exposed and easy to tin, that is to say, the purpose of "copper exposure" is not separated by anti soldering ink.

The most common PCB window opening is seen in the gold finger, which is the electrical connection pin between PCB and other equipment such as mainboard, chassis, etc. it is used for "plugging" in products. Because a thin layer of gold is plated on the nickel plating layer of copper foil, the English "binding finger", it is called "gold finger". We are familiar with the computer memory module and have a golden finger structure. People who have disassembled the computer know that the memory module has a golden finger on one side, and the golden finger on it is to open a window, plug, and play.

In general PCB manufacturing process, the gold finger is made by "opening window", that is, there is no anti welding (green paint) between its pads, so as to avoid the anti welding falling off caused by long-term plugging and plugging, which will affect the quality of the product itself. In addition, window opening has a common function, which can increase the thickness of copper foil in the later stage of tin ironing to facilitate excessive current, which is more common in the power board and motor control board.

How to realize the PCB window? Take Altium designer 10 for example, if you want to open a window on the top layer, you only need to place the same line as the wire on the top solver layer. Similarly, if you want to open a window on the bottom layer, you only need to place the line on the bottom layer.

But there are exceptions. If it is a general SMD (one of the SMT components), it is necessary to avoid this problem. In PCB layout design, pad spacing should be increased or pad size should be reduced. However, because the PCB media layer itself has the property of non-tin affinity, it has the ability to block the bridge originally, so in principle, it will not cause short circuit problems.
