Pin header, a type of connector, English name: Pin Header.

This type of connector is widely used in PCB circuit boards in electronics, appliances, and instruments. Its function is to act as a bridge between blocked or isolated circuits within the circuit, and to undertake the task of transmitting current or signals. Usually used in conjunction with the busbar to form a board to board connection; Or used in conjunction with electronic wiring harness terminals to form board to wire connections; It can also be used independently for board to board connections.

Due to the different specifications required for different products, there are also various types and specifications of pin headers. According to the electronic industry's pin header connector standards, they can be roughly classified into eight categories based on spacing: 0.8mm, 1.0mm, 1.27mm, 2.0mm, 2.5mm, 2.54mm, 3.96mm, and 5.08mm; According to the number of rows, there are single row needles, double row needles, three row needles, four row needles, etc; According to the packaging rules, there are SMT (horizontal/vertical mounting), DIP (direct insertion/bending insertion), etc; Divided by installation method: 180 °, 90 °, SMT representation

Needle count: 2P to 100P

Pin: straight foot, bent foot SMT；

Pin material: brass or phosphor bronze;

Insulator materials: plastic PA66, PA46, PBT, PA6T, PA9T, PPS, LCP, etc.

Surface treatment: Gold plating (0.8u ", 1u", 3u ", 5u", etc.), tin plating, semi gold fog tin, semi gold bright tin.

Packaging: PE bag, roll bag, tube packaging.

Processing technology: First, process the pins with brass (or phosphor bronze) as required, and then nickel and gold plating as required. Then, use a mold to process the insulator part, and finally insert the pins onto the insulator according to the size requirements on a dedicated equipment.

Needle setting application: ● Data processing ● Computer ● Program control equipment ● Electronic measuring equipment ● Automatic control ● Automation ● Communication

Note: There are many factors that affect the price, and usually the ones that have the greatest impact are gold plating thickness, needle length, PIN number, etc.
