ly used inside equipment, rather than being used as a
connector on the outside of the device.[1]
Normally pin headers are pin through hole (PTH) de-
vices, but surface-mount technology (SMT) versions also
exist. In the letter case the solder sides of the pins are
simply bent on a 90 degree angle so as to be soldered to a
solder plane. If pin headers are optional, the PTH variant
is often chosen for ease of manual assembly. Pin headers
can be either straight or angled. The latter form is often
used to connect two boards together.
Pin headers are cost-effective due to their simplicity.
Headers are often sold as long strips (typically 40 pins for
the dual row versions) which can easily be broken off to
the right number of pins.
Pin headers with a plastic guide box around them are
8x2 male pin header known as "box headers" or "shrouded headers" and are
normally only used in combination with a ribbon cable
connector. A notch (key) in the guide box normally pre-
vents placing the connector the wrong way around.[2] In
absence of a guide box one pin in the header may be miss-
ing, this corresponding with a filled hole in the corre-
sponding ribbon cable connector, to assure correct orien-
tation.
