Pins
·
Socket pins are pressed in place and then soldered.
Soldered pins offer the lowest cost in pin terminals.
Pins can be swaged to the circuit and soldered after
the swaging procedure. Or, pins can be swaged to a
FR-4 stiffener and then soldered. Swaged/soldered
pins are moderately priced and have good mechanical
strength.
·
Brazed pins and ribbon, applied with a welding
technique (melting point 618°C), are also available,
and can provide a weldable surface for subsequent
assembly.
·
End pins that are in line with conductors can be
brazed, soldered, or crimped to conductors. Pins can
be bent to form a staggered arrangement.
·
Flex-circuits can interface to hardboards via soldered
lap joints, lap joints applied with an anisotropic
adhesive (conductive in the Z-axis only), compression
dots using a raised metal dot, or `zebra' strips.
Compression methods usually require a stiffener
behind the contact area.
Pins can be inserted separately or ganged in a header.
Minco recommends using a FR-4 or polyimide stiffener
in pin areas to improve mechanical strength and
simplify assembly.
