PC/104, PC/104-Plus
PC/104 and PC/104-Plus are standards for Computer-on-Modules (CoM) used in industrial computers. Unlike other common form factors, these modules are stacked, allowing for the creation of complex computing systems. PC/104 and PC/104-Plus deliver full hardware and software compatibility in an extremely small form factor (96 mm x 90 mm) with a standardized bus system (ISA). Thanks to this standardization, different PC/104 cards can be combined to fulfill specific application requirements.

The PC/104 and PC/104-Plus Standards

Due to increasingly powerful components, it became necessary to expand the PC/104 system with a faster bus system. For this reason, the PC/104 system was supplemented with the PCI bus. This addition was referred to as the PC/104-Plus specification.
PC/104 and PC/104-Plus connector
While the PC/104 bus consists of two connectors—with 40 and 64 pins, respectively—that can be arranged in parallel and have a pitch of 2.54 mm, the PC/104-Plus offers 120 pins spaced 2.00 mm apart in four rows.
By using connectors with a transfer zone (long pins) in a press-fit configuration (press-fit technology), multiple boards can be conveniently stacked on top of one another (see figure). The spacing specified by the PC/104 Consortium is maintained through the use of standoffs and shrouds.
The additional use of standoff is therefore no longer necessary.

Developer's perspective
"ept connectors (connector) are characterized by the highest stamping quality, which is particularly evident in the clean embossing of the contact pins. The build quality and available performance levels ensure a high number of mating cycles. ept PC/104 and PC/104-Plus connector are shipped with the well-known and proven Tcom press® press-fit zone, thereby ensuring the highest reliability in every conceivable application.
For this connector, the female contacts are pressed in using a simple flat-plate press-in tool. This eliminates the costs associated with time-consuming hand soldering, and no rework is required on the transfer posts. (Solder bridges, tin splatters) When press-fitting the ribbon cables with transfer posts, a guide body (pin guide) is slid on from below to stabilize the transfer posts. This also serves as a spacer (standoff), ensuring that the 0.6" spacing is maintained when the modules are mated."
