How to distinguish the quality after the terminal is tinned

Connectors are widely used in our lives. The function of the connector is to build a communication bridge between two unconnected components, so that the circuit or electrical signal is unblocked. The main components of the connector are (the main components of the car connector are: contacts, shell (depending on the type), insulator, accessories): terminal (Terminal), housing (Housing), needle seat (Wafer). Today we mainly talk about connector terminals.

Terminal combination series terminal block/connector terminal

The connector terminals are generally made of phosphor copper or brass as raw materials, processed by a terminal machine through a program. The terminals are divided into male and female or female and male. The terminals are generally round and square. Generally, because of the circuit circulation between the circuits, corrosion, oxidation and wear resistance, the surface of the terminal will be plated with a layer of metal, usually tin plating, plating Silver and gold plated. Among them, gold plating is expensive, so sometimes we choose half-gold plating in order to achieve the same effect and considering the cost. The inspection of metal terminals after electroplating is an indispensable step after electroplating. Only the products that pass the inspection can proceed to the next process. Usually, the inspection specifications for metal terminals after electroplating are: appearance, film thickness, adhesion, soldering ability, corrosion resistance test and packaging.

First check the appearance. In this step, Z can intuitively see whether the connector terminal is qualified after electroplating, and then the next step. Some steps will use professional instrument testing equipment, etc., which require the connector manufacturer to strive for perfection in every step.
