What is the role of connector plating

People who often buy connectors, carefully observe the plating indicator on the connector. We will find that the alignment may be small and not very beautiful, but it is this arrangement that is not very beautiful, but it is the most important of any connector. One of the components. However, it is not a difficult thing to make the appearance of the connection better. Some of us can plate the connection, so that it can be a good replacement. So what is the role of electroplating the connector plating? Konnra connector engineer will come to you to popularize the effect of electroplating the connector connection plating.
Terminals with gold plated
Konnra connector engineers pointed out that electroplating is the process of depositing another layer of metal on another metal. Simply put, it is achieved by using a series connection and a liquid solution containing the plating material. What are the benefits of the plating process?
Connector conductor plating has many effects. A good connection of the plating layer can ensure the best conductivity of the circuit. When the basic material of the connection is conductive, the plating will reduce the resistance of the interconnect itself, which makes it easier for current to flow through the connection.
The electroplating process of the connector conductor can achieve mechanical purposes. Rubbing two metals will cause friction and damage, and a layer of plating can protect the underlying metal inserted below. For many reasons, gold is often replaced by electroplating materials, which has excellent electrical conductivity, and gold is also a precious metal and does not react with other materials, which makes it very suitable for contact plating. Because gold does not oxidize or change color in the atmosphere, it has long-term durability in harsh environments.
Terminal with Tin plated

From the point of view of manufacturing cost, tin can sometimes replace gold. Although tin is not as wear-resistant as gold alloy, it also has the advantage of good combination with solder, which is very suitable for use on printed circuit boards (PCB). In fact, in order to combine the quality of gold and tin, the two are often plated, and the mating area of the connection is plated with gold to provide the best mating surface. The terminals are tinned to provide the best connection when soldering to the PCB. This process is called selective plating.

What is the coaxial connector?

图片
Coaxial connectors are used to transmit RF signals. They have a wide transmission frequency of up to 18 GHz or higher and are mainly used for radar, communication, data transmission and aerospace equipment. The basic structure of the coaxial connector includes: a center conductor (a positive or negative center contact); a dielectric material outside the inner conductor, or an insulator, and the outermost is an outer contact, which serves as a shield outside the coaxial cable. The same function of the layer, that is, the signal transmission, the grounding element as a shield or circuit. The coaxial connectors are mainly divided into: SMA, SMB, BNC, TNC, SMC, N-type, BMA, and the like. Male: Male (plug), thread inside, inside is the needle. Such as TNC (M). Female: Female (socket), threaded outside, inside is a hole. Such as SMA (F). RP: Reverse Polarity means that the head and the inside of the needle are opposite. Bulkhead: It is the joint of the lockable screw on the board and...

The optical fiber connector

图片
A fiber optic connector is a detachable (active) connection between an optical fiber and an optical fiber. The two end faces of the optical fiber are precisely butted together so that the optical energy output from the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. It also minimizes the impact on the system due to its involvement in the optical link, which is a basic requirement for fiber optic connectors. To some extent, fiber optic connectors affect the reliability and performance of optical transmission systems. Basic introduction A connecting device for re-plugging between optical fibers, also called a fiber optic movable joint. The main performance parameters (and typical values) are: insertion loss (<0.5dB), plug-and-repeat repeatability and interchangeability between connectors (500 changes). When used in a large-capacity high-speed transmission system, reflection is also required to be small. Introduction Optical fiber con...

The working principle of IDC termination method

图片
Introduction and background IDC termination method is often used in various applications. This termination technology has been successfully applied to a variety of industries where multi-contact mass termination and very economical. Multi-point cable termination can be achieved with insulation displacement  connectors (IDC)  because the termination force is relatively small (usually a few pounds, while crimping is hundreds of pounds). In addition, another advantage of this technology is that it eliminates the stripping operations required in crimping. Therefore, in many electronic applications, such large-scale terminations are often used when using multi-strand cables. In many cases, multiple flat cables are used for this very economical large-scale termination. However, discrete multi-strand cables can also be used to reduce costs because the steps of cable stripping preparation and terminal insertion are eliminated. This type of application provides rapid assembly of high-d...
