3M designed the PC104 and PC104 Plus Connectors to meet the specifications of PC/104 Embedded-PC Modules in Embedded Systems Applications. 3M offers the PC104 8-bit J1/P1 and 16-bit J2/P2 Connectors in both stack-through and non-stack-through versions with solder tail termination. The PC104 Plus Connectors offering
incorporates the PCI bus within the PCI/104 form factor, and includes
the J3/P3 32-bit non-stack-through module with solder tail termination
and the stack-through module with press-fit tail termination. The
stack-through design meets the compact space requirements of embedded applications and
provides rugged performance against shock and vibration. In addition,
the self-stacking bus eliminates the need, cost, and bulk of backplanes and card cages while the relaxed bus drive (6 mA) lowers power consumption (to 1-2 watts per module) and minimizes component count.
