Drawn wire pin technology is a total process solution that offers a large variety of pin sizes, types and features along with a continuous packaging format compatibility with high speed automation. This flexibility along with high-speed automation provides the lowest applied cost for any interconnect pins available on the market.

The drawn wire pin technology allows you to design a component to your exact specifications without costly engineering charges. Along with specialized component capability all PCB pins are also designed with automation in mind. Autosplice's automation technology is compatible with both through-hole and SMT process technologies. The Autosplice end-to-end PCB pins offer a single turnkey process solution to mixed technology manufacturing.​​

Component Features

All drawn wire PCB pin products are supplied on continuous reel, notched at each end to your exact length specification. The notch creates a tapered lead-in, eliminating the potential for board damage during assembly. Additionally, end-to-end pins can be supplied with a variety of features designed to maximize component to board retention for both soldered or solderless connections.

Continuous Reel Pin Packaging


Packaged end-to-end on continuous reel, PCB pin components are ready for machine assembly at various levels of automation. The same component reel supplies pins to Semi-Automatic, Stand-Alone or In-Line Insertion systems. Additionally, the modular insertion tooling for all systems are interchangeable for future machine upgrades.​

Retention Frame

Solid Press-fit / Star Pin

A connection formed when the sharp corners of a component displace material on insertion. In a typical PTH (plated-through hole) the copper underlayer is displaced or deformed.​


  • Stable Mechanical Soldered Connection

  • Strain relief soldered electrical interconnect

  • Requires tight tolerances of PCB insertion holes; Typically +/- .002" for pin sizes less than .025", PCB hole tolerance is +/- .001"

  • Recommended for use with single or double-sided PCB's and plastic substrates

Barbell Compliant Fit drawn wire end-to-end Pin

Barbell Compliant Fit Pin

A connection is formed when a spring loaded press-fit section collapses and complies with the plated through PCB holes. This interconnect forms a gas tight connection with a plated through PCB hole eliminating the need for soldering. Barbell is available in .025" square pins and is a direct solderless replacement for Industry standard .100" centers/pin headers.


  • lnsertable into plated-through PCB holes only

  • PCB insertion hole tolerance of ±.003"

  • Solderless gas tight connection

  • Recommended for use with double sided and multilayer PCB' s

Large collapsing gap offers wide insertion range of +- .005

Large collapsing gap offers wide insertion range of ±.005

Conforming Fit Pin

A connection that is formed when a spring loaded press-in section collapses on insertion, forming a reliable termination across a wide range of hole sizes and PCB materials.


  • Insertable into all PCB types or materials

  • Solder hole tolerance of ±.005"

  • Solderless hole tolerance of ±.003"

Square Pin

Round Pin

Knurled Pin

These pins offer enhanced retention properties especially when inserted into plastic substrates and thinner PCB's. The knurled feature also allows for insertion flush to the bottom side of a PCB for compatibility with bottom side SMT process stenciling and subsequent reflow operations.


  • Soldered connection

  • Insertable into PCB's or plastic substrates

  • Low profile PCB insertion allows for screen paste and subsequent SMT compatible reflow processes

Coined drawn wire end-to-end Pin

All four corners are coined for smaller cross section

Coined Pin

Available as an option on all square pin sizes, the coined section serves the following functions:

  1. When inserted into plastic, the coined section acts as a non-interference zone. This eliminates potential damage or dragging of substrate material when long inserted lengths ore required.​

  2. When used as board to board interconnects, the square end is inserted into a mother board. The coined end presents a smaller target to the holes on the daughter cord. This makes aligning hundreds of pins to PCB holes easy.
