PCB/Panel Mounting

MOTM

PCB Mounting Brackets

MOTM PCBs are generally mounted perpendicular to the panel with L-shaped brackets affixed to pots or jacks.

Available at:

MU

Synthesizers.com and some 3rd party manufacturers mount the PCB parallel to the panel with standoffs. Other 3rd party manufacturers mount PCBs perpendicular MOTM-style. #4-40 mounting hardware is ideal, and works with CGS boards too.

PCBs can be mounted parallel using 1" (Mouser: 534-8405) and 1.25" (Mouser: 534-8407) threaded standoff posts.

Black oxide screws, like the ones used by Synthesizers.com, are used to affix the standoffs to the front panel. Specifically, #4-40 x 3/8" Black oxide phillips pan head screws. [1]

Screws available here: http://www.aaronsmachinescrews.com/cfusion/DisplayProduct.cfm?ITEM=1701SN1368

For perpendicular mounting, brackets as mentioned in the MOTM section can be used, or threaded right-angle brackets (Mouser: 534-621) can be mounted to the panel, using the same screws mentioned above. [2]

Notes

  • I'm not wanting to do a list of every possible panel part or knob (everyone has preferences), but to list the common/major/most-wanted parts in these formats. I'd love to eventually list the sizes and have templates/sizes for panel design too.
  • Some of this info I've taken from others sites (so far just from manufacturers). I haven't explicitly credited them for that info, but have linked to them in places. If people think this needs explicit credits, rather than just a link in the "additional resources" section needed, I can do that.
