　　Next, let us introduce some common sense about round hole female headers, and hope to help us.

　　Round hole pin header female connector, English name: Pin Header. This kind of connector is widely used in PCB circuit boards in electronics, electrical appliances, and appearance. Its function is to function as a bridge between blocked or isolated circuits in the circuit, and is responsible for current or signal transmission. mission. Generally used in conjunction with female headers to form board-to-board connection; or in conjunction with electronic wiring harness terminals to form board-to-wire connection; it can also be used independently for board-to-board connection.

　　Because the specifications required by different products are not the same, there are also many types of specifications for pin headers, which are classified according to the specifications of the pin header connector of the electronic industry:

　　According to the distance, it can be roughly divided into five types: 2.54mm, 2.00mm, 1.27mm, 1.00mm, 0.8mm. According to the number of rows, there are single-row needles, double-row needles, three-row needles, etc.; according to the packaging method, there are SMT (horizontal stickers) /Vertical paste), plug-in DIP (straight plug/curved plug), etc.; according to the device method: 180° is indicated by S, 90° is indicated by W, and SMT is indicated by T.

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

　　Number of needles: 02to80

　　Stitches: straight, bent, SMT; the size of the needle.

　　Dimensions: shape dimension length, width, thickness, row spacing.

　　Distance: There are 0.8, 1.0, 1.27, 2.0, 2.54 distances.

　　Raw materials: refers to the raw materials and surface treatment of contact parts, and the raw materials of insulators.

　　Packing: blister pack, roll bag, bulk pack.
