Introduction to the use of row of needles and application technology
2022-12-20
Application: smart meters, meters, carriers, UPS, inverters, car recorders, car alarms, network switches, routers, notebooks, computers, MID. digital cameras, boards and smart communication products, smart home appliances, etc. .
The role of the row of pins: its role is to be blocked in the circuit or isolated between the circuit, to play the function of a bridge, to take up the task of current or signal transmission set to make. Usually used with the mother of the row, forming a board-to-board connection; or with the electronic harness end, forming a board-to-wire connection; can also be used independently for board-to-board connection.
Pin classification and types.
1, according to the spacing of the row of pins: 0.8mm, 1.0mm, 1.27mm, 2.0mm, 2.54mm spacing.
2, according to the height of plastic and the number of plastic division (for example, single plastic, double plastic, 3 plastic, etc.)
3.Divided according to the number of rows of pins: divided into a single row, double row, 3 rows, 4 rows, etc.
4, according to the installation mode: 180 degrees with S, 90 degrees with R, SMT with M.
Pin packing method: bagged, tube, rolled.
Pin material: pin material: brass or phosphor bronze; insulator material: plastic UL 94V-0.
Surface treatment: gold-plated 0.8u, tin-plated, nickel-plated
Pin processing process: Pin processing process is mainly: first according to the requirements of the brass (or phosphor bronze) processing good pin, and according to the requirements of the first nickel plating and then gold plating, and then use the mold processing good insulator part, and finally in the special equipment according to the size requirements of the pin set to the insulator.
