500 series board size and L bracket
« on: January 03, 2021, 10:10:21 AM »
Hi!

I'm currently finishing the design of a 500 series preamp based on the VPR alliance dimensions specs.

From this pdf information, if I add an L bracket made of 1mm thick aluminum, between the pcb and the front panel, I have to diminish the size of the board by 1mm accordingly.. ¿is this correct?. If i don't do this the front panel would not make proper contact to the case rim. ¿right? My board length is right now 150,51mm.

Thank you for your advise!!

I am no 500 series expert but the front panel shown in the drawing is 0,125 inches thick which is 3.175mm. I suspect most manufacturers use the full PCB size and use a 1mm steel L-bracket and a 2mm aluminium front panel.

The typical way is to subtract the L- bracket thickness from the PCB length.

Of course because the rear of the front plate still has to mate with the lunchbox face. Silly me.
