PC/104 Plus 22mm

PC/104-Plus 22mm

PC/104 is a standard for PC-compatible modules which are intermateable to set up a complete embedded computing system. PC/104-Plus features 120 pins with a distance of 2.00 mm and the female connector is now available in both the standard height and this higher design, permitting a board to board distance of 22 mm and thus the stacking of more components: for example heat sinks, fans, power modules etc.

Description

Description

Standard PC/104 connectors accommodate a board to board distance of 15.24 mm. This was usually enough to connect two boards. However, with the ever increasing requirement to connect more components, for example heat sinks, fans and other cooling systems, manufacturers now often need a greater distance. As a specialist for connectors ept has reacted to this need and as a result is now the first provider to have a suitable connector in its lineup. The PC/104-Plus Female connector is available both in the standard height as well as in this higher design, permitting a board to board distance of 22 mm.

ept is offering PC/104-Plus connectors with both short and long pins. The long pins enable additional circuit boards to be connected directly (rear mating zone plated performance level III), which means the new connector can be combined with all existing and available PC/104-Plus boards.

While the PC/104 bus comprises two connectors with 40 and 64 pins which can be placed side-by-side and a grid size of 2.54 mm, the PC/104-Plus features 120 pins with a distance of 2.00 mm. The superior option for applying a long tail stack-through connector is with compliant pin technology. Adopted by the telecom industry many years ago, ept press fit technology has proven itself to be a cost-effective alternative to soldering connectors to a board. The compliant pins on the connector are designed to deform during the “press-in” process, resulting in an extremely tight and reliable connection to the PCB.

Key Features

Key Features

  • PC/104 and PC/104-Plus Embedded Consortium Member
  • Accommodates a board to board distance of 22mm
  • Press-fit compliant pin which compresses as a result of insertion into the PCB ‘through hole’
  • Female connectors can be pressed in with the same ept press-fit tool in one single step ~ offering significant time-savings in production.
  • No complex manual soldering ~ lower labour costs
  • No reworking at the rear mating zone (solder bridges, solder splashes)
  • Lower engaging and separating forces so bending of the rear mating zone is prevented
  • Press-fit tooling and machines

Applications

Applications

The older standard PC/104 bus uses the PC/XT, and PCAT card specification (IEEE P996). PC/104-Plus allows the addition of the PCI bus onto the card. The PC/104-Plus adds another connector to accommodate the PCI signals. In other words a PC104 card is just like the old Personal Computer PC-XT interface card, or PC-AT interface card, and the PC104-Plus board is just like an older mother board with ISA slots and PCI slots. This latter standard is widely used for embedded computing application

  • Complete single-board computers
  • I/O boards for digital or analog I/O
  • Boards for CAN, Profibus, LON,Ethernet
  • PCMCIA boards
  • PC/104-Plus
  • Board-to-Board for PCB distance 22 mm
