What is a PCB Pin?

Printed circuit board (PCB) pins are tubular shaped male connectors used to carry electrical current within PCB assemblies. Printed circuit pins are available loose or grouped together in what are called pin headers.

Mounting PCB Pins

PCB pins are mounted to the board utilizing either through-hole technology (THT) or surface mount technology (SMT). Through hole (THT) mounted pins are inserted in pre-drilled holes in the board and then soldered in place. Surface mounted (SMT) pins on the other hand are soldered directly to the top of the circuit board without any drilling required.

PCB Pin Configurations

In addition to mounting style there are many other PCB pin variations available.  Contact materials range from brass to nickel while common plating materials include gold, tin, and copper.

Popular PCB Pin Styles

  • Nail Head Pins
  • Slotted Terminal Pins
  • Wire Crimp Pins
  • Swage Terminal Pins
  • Double-Tail Header Pins
  • Press-Fit Pins

Superior Press-Fit Pins & Receptacles from Mill-Max

Leading PCB interconnect manufacturer, Mill-Max, understands that quality is critical when it comes to printed circuit board connectors. That’s exactly why Mill-Max has designed its line of press-fit pins and receptacles to meet the highest industry standards.  Using proprietary manufacturing methods, pins and receptacles are high speed turned to meet precise tolerances and plated to ensure superior conductivity and corrosion resistance.

Mill-Max’s precision turned press-fit pins and receptacles offer many benefits over traditional stamped and formed connectors.

Benefits of Precision Turned Pins & Receptacles:

  • Seamless construction prevents contact contamination from wave or reflow soldering.
  • Specialized press-fit feature geometries – triangle, square, hexagon, octagon – to meet the hole size requirements of specific applications.
  • Lead-in countersinks on pin receptacles to facilitate pin alignment.
  • Pin and receptacle shells are brass alloy, 360 ½ hard, for strength, conductive and thermal properties.
  • Multi-finger beryllium copper contact clip scores the mating device lead for gastight electrical connection and provides best power and force distribution.
  • Two-piece receptacle construction (shell and contact clip) allows for cost efficient plating combinations for best solderability and conductivity.
