SSEMBLY
The VSBC mounts on four 4-40, 3/8" hardware standoffs using the corner mounting holes (A).
These standoffs are secured to the underside of the circuit board using 1/4" 4-40 pan head
screws.
Four additional 4-40, 3/8" standoffs (B) must be used under the circuit board to prevent
excessive flexing when expansion modules are mated and demated. These are secured with four
4-40, 5/8" male-female standoffs (C) threaded from the topside which also serve as mounting
struts for the PC/104 stack.
The entire assembly can sit on a table top or it can be secured to a base plate. When bolting the
unit down, make sure to secure all eight standoffs (A and B) to the mounting surface to prevent
circuit board flexing. Refer to the drawing on page 13 for dimensional details.
An extractor tool is available (part number VL-HDW-201) to separate the PC/104 modules from
the stack.
Note! Standoffs and screws for (A and B) are available as part number VL-HDW-104.
Standoffs and screws for (C) are available as part number VL-HDW-100.
