About ICREX

his is a company that offers proposal-based products in custom production that lead mainly to the solution of board connection problems.
We develop and produce parts based on our custom standard product group, which has been cultivated over many years to solve problems such as "Isn't it possible to make such a part? I wish I had such a part."
It has been used in many cases where "off-the-shelf standard products do not meet the specifications, or there are no standard products in the first place."

Overall product guide

Basically, there are no standard or inventory products because they are made to order for custom products.

All products are RoHS compliant.

At ICREX, we provide standard products that serve as the basis for a wide variety of custom products as the basis for creating solution products.


Use primarily to connect boards

Mainly used in the connection between substrates and molded products

Be used by mounting on a substrate

Primarily join wires together

In addition

There is no price list because it is a uniform custom product.

The minimum lot of Semi-Custom Pin Headers and Female Headers is 3000 except for the prototype.
For other products, we do not decide in particular, so please consult with us.

Full Custom Pin Headers

Proposal-based products that lead to the solution of board connection problems.
This pin header solves such problems as "the thickness, length, shape, and pitch of the terminal," "it is difficult to use with standard pin headers made off the shelf due to the specifications," and "it cannot be found with existing products."

Preform Chain Terminal Insert Systems

This is a system for directly inserting terminals into circuit boards or molded products. It consists of a continuous terminal and a continuous terminal insertion machine.
Separate the continuous terminals one by one and insert the terminals directly into molded products such as printed circuit boards and bobbins.
We offer preform chain pin terminal insert system and preform chain tab terminal insert system.
This system is mainly used as a mechanical component for electrical connection between printed circuit boards and as a terminal for bobbin winding.

It is used for such things.

  • Terminals can be inserted without cutting the collective board into individual pieces.Image of terminal insertion on collective board
  • Since the terminal is inserted directly into the workpiece, no insulator is required, saving space.Image with and without insulator
  • Terminal shape is gentle on workpieces, as the tip of the pin does not scrape the pilot hole of a printed circuit board or molded product when inserting the terminal.Image of terminal shape
  • A method that allows soldering to be completed on a reflow line is possible (conditions apply)Image of reflow soldering of terminals
  • Unlike terminal insertion tools, the pitch and position of inserting the terminals can be determined by the insertion machine program.Image of controller

The Preform Chain Pin Terminal Insert System, which constitutes the Preform Chain Terminal Insert System, is a system in which pin terminals connected vertically in a chain are separated one by one by a terminal insertion machine and directly inserted into a printed circuit board or bobbin.

Image of preform chain pin terminal insert system

This is a vertically connected continuous pin terminal. It is wound on a reel.
As long as it is within the basic specifications, you can specify the length and thickness of the terminal without any initial cost.
We also have the option to add flanges and other processing depending on the application.
The tip of the terminal is pyramid-shaped and will not damage the hole in the workpiece when inserting the terminal.
By adding star processing to the press-fitting part of the pin terminal, the adhesion strength can be increased.

The Preform Chain Tab Terminal Insert System is a system in which continuous tab terminal made by press processing are separated one by one by a terminal insertion machine and directly inserted into a printed circuit board or bobbin.

Image of basic specifications of preform chain tab terminal

This is a custom tab terminal made by manufacturing a press die.
There are no standard or off-the-shelf products.

Image of preform chain tab terminal

This machine inserts a preform chain terminal made by ICREX into a workpiece.
For the preform chain pin terminal, the desktop type and the stationary type are available as standard machines. Custom models with a workpiece loading/unloading unit are also available.
Custom support is available for the preform chain tab terminal.

Crimping System

This crimping system is effective for connecting wires to each other, wires to lead wires, and lead wires to each other.
This highly reliable wiring system consists of a ribbon terminal that becomes a crimp terminal, an applicator that converts the ribbon terminal into a crimp terminal, and a ribbon crimper that drives the applicator.

Image of Crimping System

ICREX Crimping Systems are used in a variety of fields, including home appliances, automobiles, and telecommunications equipment.

  • Temperature sensors such as thermistors, temperature fuses, temperature-sensitive reed switches, and thermocouples
  • Display or illumination using LEDs
  • Connection with electronic components such as resistors, diodes and capacitors

  • Compared to manual soldering, the quality is more stable because the wires are connected mechanically.
  • Compared to crimping with formed terminals, the range of workpieces that can be crimped is expanded.
  • No scraps

The Ribbon Terminal is a strip-shaped terminal wound around a reel that attaches to the crimper ribbon crimper.
It eventually changes to a crimp terminal.
The Ribbon Terminals are serrated in a wave shape and are designed to increase the area of contact with the workpiece to be crimped. This serration improves electrical properties such as contact resistance and mechanical properties such as tensile strength.

Image of Ribbon terminal

The applicator is a tool attached to the ribbon crimper of a crimping machine that cuts and forms ribbon terminals into crimp terminals.
The size of the crimp terminal is determined by the applicator, and the type of applicator is determined by the size of the work to be crimped.

Image of Applicator

This is a machine that drives the applicator to convert ribbon terminals to crimp terminals and connects workpieces in about 0.2 seconds.

It is possible. Consult us.

Printed circuit board with terminal

This is a product that can reduce the amount of work required to attach terminals later.
Printed circuit boards with terminals attached in advance will be manufactured.
This product is possible because we handle everything from terminal production to terminal insertion as a system.

Image of Printed circuit board with terminal

Can be handled.

The know-how gained through the terminal insertion system prevents the terminal from falling off the board by providing an overhang on the terminal itself and fitting it into the board through hole.

Image of terminal press-fitting

The soldering method differs depending on the state of insertion of the terminal. For details, please consult us.

Flexible board connectors

This is a component that can flexibly connect boards realized by using magnet wires in the conductor section.
The degree of freedom in the connection form between boards is improved.

Image of Flexible board connectors

The board can be installed in various arrangements after the board flexible connecting parts are soldered.
It is thin.
Custom specifications such as length, number of contacts, and pitch are available.

There is FiP-01 which is easy to bend in all directions. Also, please consult us regarding specifications that do not apply to FiP-01.
