This page shows the basics of materials and plating for board to board pin headers.

View all Board to Board Connectors


Base material

Base pins are produced from either brass or phosphor bronze.


Lowest cost.
Good spring properties and strength.
Reasonably good conductor.

Phosphor Bronze

Good strength and conductivity.
Superior elasticity.
Excellent fatigue resistance.


Base pins are underplated with nickel and a finish plating added for improved conductivity, high temperature protection and resistance to corrosion and wear. Finish plating is available in variants of gold or tin.


Excellent corrosion resistance and durability.
Excellent conductivity and low electrical resistance.
Various thicknesses available.


Excellent solderability and conductivity.
Lower cost.
Available in bright or matte.


Gold in contact area, tin in solder area.
Tin provides best solderabily in PCB area.
Gold provides best conductivity in mating area.
