Precautions for purchasing contact fragments
04-28 / 2023

Contact shrapnel belongs to the category of hardware shrapnel and electronic hardware materials. It is an important component on various electronic products (mobile phones, connectors, car batteries). Produced by processing metal materials. When the contact spring piece installed on the conductive film is pressed, the center point of the spring piece contacts the PCB board to form a circuit, and the current passing through it has characteristics such as strong conductivity and good touch.


Contact spring production process: A special process of stamping metal materials into parts through cold stamping using stamping molds. It is a stamping process that uses a mold installed on a press to apply pressure to the material at room temperature, causing it to separate or deform plastically, thereby obtaining the required hardware.


As an important hardware component in electronic systems, contact shrapnel has a large usage and a wide variety of types. The production of hardware shrapnel has been primitive manual production, gradually moving towards mechanical automation. At the same time, the technological performance of hardware shrapnel is also on the rise.

Precautions for purchasing contact shrapnel:


1. Materials used for contact with shrapnel:


When making contact shrapnel, it is important to select appropriate materials normally and not choose them as cheap as possible. Each material can also be separated into several different small materials, but many manufacturers can distinguish which materials produce high-quality products. So when choosing contact shrapnel, we should pay attention to the materials used.


2. Force of contact with shrapnel:


Many foreign customers have very strict requirements for the strength of the contact shrapnel, which means that the strength of the contact shrapnel we use should be uniform and should not be high or low. Of course, we can control the strength within a certain tolerance range (± 20gf).


3. Life of contact fragments:


At present, many contact shrapnel in our country have a service life that does not meet the standard. Although the price is relatively cheap, we cannot buy inferior contact shrapnel just because of the cheap price. Therefore, when choosing contact shrapnel, we should pay attention to its service life.
