The color of the gold-plated layer of the pin jack of the aviation plug connector is inconsistent with the normal color of the gold layer. When the thickness of the outer surface of the plating exceeds the specified value after the gold-plated process of the pin or jack is completed, the coating of the inner hole of the welding hole or jack is very thin or even without the gold layer. Then, the reasons for the problems are as follows:

1, aviation plug connector jack is not plated with gold:

When the thickness of the outer surface of the plating reaches or exceeds the specified thickness, the coating of the inner hole of the welding line hole or socket is very thin or even without gold layer.

2. When the jack of aviation plug connector is gold-plated, the plating parts are inserted into each other:

Order to ensure the sockets in the socket connector plug has certain elasticity, when used in the product design in most kinds of jack have is a split groove in the mouth design. In the process of electroplating plating pieces evenly done part of jack at the opening of each other together the inserted parts electric shielding each other cause jack in electroplating.

Iii. When the pins of aviation plug connector are gold-plated, the plating parts shall be connected end to end:

In the design of some types of connectors, the outside diameter of the needle rod is slightly smaller than the aperture size of the welding line hole. In the electroplating process, the middle part of the inserting needle will form end-to-end connection, resulting in no gold plating in the welding line hole. These two phenomena are more likely to occur in vibration gold plating.

Iv. Large concentration of the blind hole in the air plug connector:

Due to the bottom of the groove of the socket from the bottom of the hole and a distance, the distance objectively formed a blind holes. Also the pin and socket welding line also has such a blind hole in the hole, it is to provide the guiding role of wire welding. When these holes smaller aperture (often less than 1 mm or less than 0.5 mm) and blind hole concentration exceeds the aperture plating solution is very difficult to flow into the hole, flow into the hole of the plating solution and it is hard to flow, so the hole of the gold layer is difficult to guarantee quality.

The anode area of the gold-plated connector for aviation plug connector is too small:

Connectors when the volume is small relatively single slot plating pieces of the total surface area is larger, in such a small pinhole if single slot when plated on more. The original anode area is not enough. Especially when platinum titanium net use of time is too long too much loss of platinum anode will reduce the effective area, this will affect the gilded deep plating ability, plating parts inside the socket will be plated.

To sum up, the above is described for you by the aviation plug connector pin jack inside the gold plating problem, I believe you have a certain understanding of this aspect of knowledge. Dongguan Jingcheng industrial co., LTD. Provides various types of application solutions for the connection of pin jacks, including connector pin jacks, spring clips, pickup pads and spring pins. Our battery connectors include shrapnel type, floating Battery Interconnect System (FBIS) and spring thimble (Pogopin), with a variety of options to meet the ever-changing needs of smartphones.
