Normally pin headers are through-hole devices (THD/THT), but surface-mount devices (SMD/SMT) exist too. In the SMD case, the solder side of the pins are bent on a 90-degree angle so as to be soldered to pads on the printed circuit board (PCB). On single row SMD headers the pins are bent alternating to one side or the other, on dual row SMD ...
Micro ribbon connector - used for 36-pin printer ports (IEEE 1284 - Centronics) and 50-pin SCSI ports. DIN 41612 connector – used for Eurocard buses. PCB transition headers – has two rows of pins with the same spacings as BT244 connectors. Intended to be soldered directly into a PCB. DIL headers – Has pins with the same spacings as ...
Connectors are categorized by pin spacing in mm (pitch), number of pins, and number of rows. Connectors commonly used in computers include: 3.5 inch IDE desktop computer hard disk drives – 2.54 mm pitch, 40 pins, 2×20 (2 rows of 20 pins)
Metal solder buckets or solder cups are provided, which consist of a cylindrical cavity that an installer fills with solder before inserting the wire. [41] When creating soldered connections, it is possible to melt the dielectric between pins or wires.
JST manufactures numerous series (families) and pitches (pin-to-pin distance) of connectors. [ 2 ] [ 3 ] JST connectors are used in many types of products, and commonly used by electronics hobbyists and consumer products for rechargeable battery packs, battery balancers , battery eliminator circuits , 3D printers , and radio controlled servos .
Solder paste is used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. It is also possible to solder through-hole pin in paste components by printing solder paste in and over the holes. The sticky paste temporarily holds components in place; the board is then heated, melting the paste and ...
