Re: [TCML] Best low cost adhesive for FR-4 to PLYWOOD

[David Speck <Dave@xxxxxxxxxxxxxxxx>]

Dan,

I would guess non-acetic acid type RTV would be the best bet.  You might 
have to sandblast the FR-4, or omit the solder mask on the adhesive 
face  before applying the adhesive to get the best adhesion if there are 
any sort of peeling forces to be applied.

A lot depends on the kinds of forces that will be applied.  If you are 
just sticking a PC board to the wood, supporting its own weight, then 
RTV should be OK.  I wouldn't count on it to withstand any sort of 
serious shear or tension loading, though.

Also will depend on whether it gets significantly warm in operation.  
Some sort of mechanical attachment -- screws and standoffs, or card edge 
guides -- might be better, especially if there is a chance that the PCB 
will have to be replaced eventually.
