PC/104 and PC/104 Plus connectors are an industry-standard connector system used in PC/104 Embedded PC module stack applications. The PC/104 module stack is designed to use less space and at a lower cost than an equivalent backplane system, by utilising stackthrough connectors to interconnect PC boards within a stack. Standard height between module boards is 0.6” (15.24mm). 8-bit Module, comprising: J1 = 32+32-way 2.54mm pitch Stackthrough connector 16-bit Module, comprising: J1 = 32+32-way 2.54mm pitch Stackthrough connector J2 = 20+20-way 2.54mm pitch Stackthrough connector J1 J2 J1 J3 J2 J1 PCI Bus Module, comprising: J1 = 32+32-way 2.54mm pitch Stackthrough connector J2 = 20+20-way 2.54mm pitch Stackthrough connector J3 = 120-way 2.00mm pitch Stackthrough connector PCI Bus Module, comprising: J3 J2 J1 J1 = 32+32-way 2.54mm pitch Non-stackthrough connector J2 = 20+20-way 2.54mm pitch Non-stackthrough connector J3 = 120-way 2.00mm pitch Non-stackthrough connector Figure 1 – PC/104 Stack PC/104 connectors are 2.54mm pitch, either 32+32 or 20+20 ways. PC/104 Plus connectors are 2.00mm pitch, 4 x 30 (120) ways. The sockets have a tuning-fork style of contact. Solder or pressfit tail options are available, as are accessories for the range (see Appendix 1). 2. MARKING OF COMPONENT AND/OR PACKAGE (ORDER CODE).
