DIL (dual in-line) headers are a type of electrical connector known as a through header. They are used to connect two PCBs (printed circuit boards). They can be used with an appropriate [DIL socket](/web/c/connectors/ic-sockets/dil-sockets/) to form a plug and socket pair, or can be directly soldered to the PCB using [soldering tools](/web/c/tools/soldering-desoldering-tools/).

### How to connect your DIL header

DIL headers have several different means of connection, and any number of individual rows of pins. Generally, one side is a series of pins which are soldered to your PCB. They can either be at a right-angle or parallel to the PCB board's surface.

Most DIL headers can be through-hole mounted. This means that you can insert the electrical components into holes that you've drilled on the PCB and then solder on the opposite side. Through-hole mounting is reliable because it provides a strong mechanical bond.

### DIL header applications

DIL headers can be used in a variety of electrical applications, including in computer power supplies or motherboards.



Connect two PCBs (printed circuit boards) safely and securely with DIL headers. Most DIL headers can be through-hole mounted to your PCB.
