Our PC/104 Products

New PC/104 Plus press-fit connectors
Known from the desktop world, the PC/104 Plus connector has been added to the PC/104 spec by the PC/104 auditors. Recently, ept has developed an electromechanical connection with the PC/104 Plus connector system in press-fit technology. This connector system presents the J3 connector in accordance with the PC/104 Plus spec in a 2mm grid.

ept offers female 4x30 contact connectors, shrouds 4x30 contact and pin headers 2x30 contact as a standard for convenient stacking of Printed Circuit Boards (PCBs). In order to meet the requirements of PC/104 Plus with pin headers, two headers are pressed-in parallely (see sketch). This offers the use of pin headers as termination of a board-stack.

ept PC/104 Plus press-fit connectors offer a large number of advantages:

  • Male and Female connectors can be pressed in with the same ept press-fit tool in one single step, thus offering a time-saving production.
  • Female connectors can be mounted cost-effectively due to flat rock technology.
  • No costly manual soldering
  • No solder bridges due to solder-free press-fit connection.
  • Reduced inspection process
  • Shroud makes stand-offs unnecessary
  • Secure assembly of shroud and board by over pressing on the connector tails.


Press-Fit PC/104 Connectors
ept now offers the VarPol-PC/ 104 female connector in FlatRock pressfit design. This connector was developed for the stacking of PCBs (Piggyback, Sandwich) and is particularly well suited for use in PC/104 modules. These connectors are available in the J1 and J2 variation with 2x32 and 2x20 pins. They can be obtained with short or long pins according to the PC/104 standard.

Advantages of the PC/104 VarPol connector with pressfit pins are the following:

  • Both female connectors can be pressed in with ept tooling in a one step process. This saves time in the production process.
  • The expenses for the difficult hand soldering process are eliminated.
  • No rework on long pins which can occur with the solder process due to solder bridging.
  • Reduced testing requirements.
  • Reduced insertion and extraction forces resulting in less possibility of pin misalignement.

During the pressfit insertion of the PC/104 connector with long pins, a plastic guide is inserted onto the pins, offering the following advantages:

  • No bending or misalignement of the long pins.
  • This performs the function of the connector offset so that a seperation of 0,6" is obtained during the assembly of the modules.
  • Serves as a supported guide during the pressing in of the connector and helps prevent damage to circuit traces.

ept also supplies various other connectors which can be used in PC/104 applications.
A few examples:

  • DIN 41612 connectors in solder and pressfit version.
  • IC- and PGA-sockets in flat rock pressfit technology.
  • IC machined sockets in flat rock pressfit versions.
  • Pressfit pins with long pins on top and bottom (support element for PC/104 female contact).
