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

Product Spotlight: Mill-Max Expands Offering of Discrete Insulated Spring-Loaded Pins

New Line of SMT Pogo Pins from Mill-Max

Mill-Max recently announced that it will be expanding its line of discrete insulated spring-load pogo pins. Mill-Max has seen increased demand for SMT pins causing them to supplement their widely used 807 series pins with the new 0907 and 0906 series SMT pins. The expanded series off spring-loaded pins will range in height from .255” (6.48mm) to .430” (10.9mm) for the 0907 series and .137” (3.48mm) to .236” (5.99mm) for the 0906 series.  Insulated spring-loaded pogo pins are ideal for applications that require electrical isolation. Nylon 46 insulators are used to isolate the pin from other conductive elements on applications such as PCBs or conductive housings.  For more technical details view the 0907 series and 0906 series catalog pages.

Product Spotlight: New SMT Gull Wing Connectors from Mill-Max

Mill-Max recently announced a new line of fine pitch SMT gull wing connectors.  Like other surface mount technology (SMT) connectors, Mill-Max’s gull wing connectors are mounted directly on the surface of printed circuit boards (PCBs) with the gull wing design (out, down, out extension of the pins) ensuring easy inspection of the soldering joints.

The new SMT gull wing connector series includes both 1mm headers with positions 3 through 26 (860-10-0XX-30-002000) and 1mm sockets with positions 3 through 26 (861-13-0XX-30-002000). Their compact size makes these SMT connectors ideal for applications where space is at a premium.  In addition, the SMT gull wing connectors feature gold plating to provide superior conductivity.  To learn more about SMT gull wing connector technical info view the Mill-Max spec sheet.

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.

4 Types of Board-to-Board Connectors

Board-to-board connectors provide a reliable plug-able connection between printed circuit boards (PCBs). Board-to-board connectors provide particular advantage in that they allow PCBs to be easily replaced and upgraded. Although available in many configurations all board-to-board connectors operate on the basic premise of male pins mating with female sockets. Among the many variations in board-to-board connectors are fine pitch board-to-board connectors, SMT board-to-board connectors, right angle board-to-board connectors, and spring-loaded board-to-board connectors.

PcB connector Types

  • Fine pitch connectors are ideal for electronic applications where space is extremely limited. Fine pitch board-to-board connectors offer low mating heights, narrow bodies, and allow for easy mating and assembly.
  • SMT connectors allow PC boards that only have surface mount components to be connected quickly and reliably. SMT board-to-board connectors eliminate requirements for drilling and can undergo reflow soldering along with other surface mount components.
  • Right angle connectors like their name insinuates allow connections at right angles. Thus vertical and horizontal PCBs can be connected without changing their orientation.
  • Spring-loaded connectors contain springs that allow for a secure connection despite fluctuations in spacing between the boards. Spring-loaded board-to-board connectors are ideal for applications like portable equipment that endure constant movement and vibration.

bisco industries offers these board-to-board connectors and many more from leading manufacturers like Mill-Max. Mill-Max utilizes proprietary machining processes to reduce connector tolerances, increase manufacturing speed, and simplify product customization.
