"Needle arrangement manufacturer" round hole arrangement of various specifications

Round hole needle arrangement of various specifications

This connector is widely used in electronics, electrical appliances, PCB board in the appearance, its role is in the circuit is blocked or isolated between the circuit, play the role of bridge, take on the mission of current or signal transmission. Generally, it is used together with the row bus to form a plate-to-plate connection; Or it can be used together with the electronic wire harness terminal to form the connection of plate-to-wire; It can also be used independently for board to board connection.

Since different products require different specifications, there are also various types of specifications for needle arrangement, which are classified according to the specifications for electronic professional needle arrangement connectors:

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

Number of rows: single row, double row, three row, four row, maximum four row.

Pin number: 02 to80

Stitching: straight foot, bent foot, SMT; The size of the needle.

Dimensions: External dimensions length, width, thickness, row spacing.

Distance: 0.8, 1.0, 1.27, 2.0, 2.54 distance.

Raw materials: raw materials for touch parts and surface treatment, raw materials for insulators.

Packing: in bubble shell, in roll bag, in bulk.

Information: Needle insertion information: brass or phosphor bronze; Insulator information: Plastic UL94V-0.

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

Processing technology: The main process of needle arrangement processing technology is: first, the needle insertion is processed with brass (or phosphor bronze) as required.

Nickel plating and gold plating as requested, and then use the mold to process the insulation part, and finally press the ruler on the special equipment

Request to insert the pin into the insulator.
