Pin Header, a type of connector. This connector is widely used in
electronic, electrical, instrument in the PCB circuit board, its
role is in the circuit is blocked or isolated between the circuit,
play a bridge function, take up the task of current or signal
transmission. It is usually used with the busbar to form a
board-to-board connection. Or matching with the electronic wiring
harness terminal, forming a board-to-wire connection; Can also be
used independently for board to board connection.
Because the specifications required by different products are not
the same, so the row of needles also have a variety of model
specifications, according to the standard classification of the
electronic industry row of needles connector: according to the
spacing can be roughly divided into 2.54mm, 2.00mm, 1.27mm, 1.00mm,
0.8mm five categories according to the number of rows of single row
of needles, double row of needles, three rows of needles; According
to the packaging rules with SMT (horizontal paste/vertical paste),
plug-in DIP (straight insert/bend insert).
Number of rows: single row, double row, three row, four row at
most.
Pin number: 02 to80
Stitching: straight foot, bent foot, SMT; The size of the needle.
Dimensions: overall dimensions length, width, thickness, row
spacing.
Spacing: 0.8, 1.0, 1.27, 2.0, 2.54.
Material: refers to contact material and surface treatment,
insulation material.
Packing: blister shell, roll bag, bulk.
Material: Pin material: brass or phosphor bronze; Insulation
material: plastic UL94V-0.
Surface treatment: gold plated 0.8U, tin plating, nickel plating.
Processing technology: Row needle processing process is mainly:
according to the requirements of brass (or phosphor bronze)
processing pin,
And according to the requirements of nickel plating and then gold,
and then use a mold to process the insulation part, and finally in
special equipment according to the ruler
The pin is required to be inserted into the insulator.
Note: there are many factors affecting the price, usually the most
influential for gold plating, needle length and so on.
Example of pin arrangement parameters
Features: single row and double row, straight needle and bent
needle, pin spacing of 2.54mm and 3.96mm, a variety of pin lengths.
