Aside from high-performance backplane design, Bustronic also develops a wide range of RTMs, Adapters, and other custom boards. Particularly for staple technologies like VME64x and new architectures like VXS or VPX, custom and standard RTM designs can be very useful. An RTM helps bring IO off the backplane in a convenient pluggable module. See Figures 1, 2 and 3 for a few examples. Injector/ejector handles help securely fix the board in place providing a more reliable connection. Direct plugging also offers better resistance to shock and vibration that ribbon cable connections.

One creative solution for RTMs is a Universal VPX RTM Breakout Board. It can allow a test engineer to access I/O signals on custom built VPX boards. See Figure 4 for a diagram. The board would not be intended for high-speed signals but would typically be used to bring out single ended TTL signals that might be part of a customer’s custom IO board.

Adapter boards can also be useful for various architectures. The images in Figure 5 and 6 show custom carriers for AMC and MCH cards for MicroTCA. Custom test extender boards are also designed for this architecture. Other custom boards in various architectures include power interface boards, overlays, form factor extenders, and load boards.

Contact Bustronic for more information on RTMs, adapters, and other custom board designs.
