PCB/Panel Mounting

MOTM PCB Mounting

PCB Mounting Brackets

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

MU PCB Mounting

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]

Internal Connectors

MOTM

Module Power

4-pin MTA-156 connectors

Pinout:

  • 1 = +15V
  • 2 = GND
  • 3 = GND
  • 4 = -15V

MU

Module Power

Dotcom modules and power supplies are connected using 6-pin keyed MTA-100 connectors. [3]

Pinout:

  • 1 = +15v (White)
  • 2 = KEY - pin missing and plugged
  • 3 = +5v (Red)
  • 4 = gnd (Black)
  • 5 = -15v (Green)

Female 24AWG cable mount: AMP #6404416 (Mouser: 571-3-640441-6)

Male PCB mount: AMP #6404566 (Mouser: 571-6404566)

Panel Connectors

2-pin MTA-100 connectors are used for jacks, push-buttons, and LEDs.

Jack Pinout:

  • 1 = Signal (tip)
  • 2 = Ground (ring)

Female cable mount: AMP #6404412 (Mouser: 571-3-640441-2)

Male PCB mount: AMP #6404562 (Mouser: 571-6404562)

3-pin MTA-100 connectors are used for switches and pots.[4]

Potentiometer Pinout:

  • 1 = CCW Side
  • 2 = Wiper
  • 3 = CW Side

Female cable mount: AMP #6404413 (Mouser: 571-3-640441-3)

Male PCB mount: AMP #6404563 (Mouser: 571-6404563)

MTA-100 connectors with more pins can be found with similar part numbers.

Additional Details

MTA-100 connectors use 24 awg wire.

MTA-100 "T"-handle tool: AMP #59803-1 (DigiKey: A9982-ND)

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, and/or what sort of things will work. I'd love to eventually list the sizes and have templates/sizes for panel design too.
