Introduction to pin header connector

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

This connector is widely used in PCB circuit boards in electronics, electrical appliances, and meters. Its role is to serve as a bridge between blocked or isolated circuits in the circuit, and carry the current or signal transmission task. It is usually used in combination with a female header to form a board-to-board connection; or used with an electronic harness terminal to form a board-to-wire connection; it can also be used independently for board-to-board connection.

Since the specifications required by different products are not the same, there are also various types of pin headers, which are classified according to the pin connector standards of the electronics industry:

According to the pitch, it can be divided into 2.54mm, 2.00mm, 1.27mm, 1.00mm, and 0.8mm. There are single-row, double-row, and three-row pins according to the number of rows. / Stand-up), plug-in DIP (Straight Plug / Bent Plug), etc .; divided according to the installation method: 180 ° is represented by S, 90 ° is represented by W, and SMT is represented by T.


Board-to-board connector


Number of rows: single, double, three, four, up to four.

Number of needles: 02 to 80

Pins: straight, bent, SMT; pin size.

Dimensions: overall dimensions length, width, thickness, spacing.

Pitch: There are 0.8, 1.0, 1.27, 2.0, 2.54 pitches.

Material: refers to the contact material and surface treatment, insulator material.

Packaging: blister pack, roll bag, bulk.

Material: Pin material: Brass or phosphor bronze; Insulator material: Plastic UL94V-0.

Surface treatment: gold plating 0.8μ, tin plating, nickel plating.

Processing technology: The pin processing technology process is mainly as follows: firstly use brass (or phosphor bronze) to process the pins,

According to the requirements, first nickel plating and then gold plating, then use the mold to process the insulator part, and finally measure the ruler on the special equipment.

Inch requires inserting pins into the insulator.

Remarks: There are many factors that affect the price, usually the most affected are gold plating and needle length.
