Subject: Attaching two PCBs together

From: "Brad" <unclefalter@...>
Date: 2017-07-18

So as I stated in a previous post, I have acquired some vintage 1973 PCB stock, which is perfect for a project I’m doing that replicates the 1973 TV Typewriter.  Except for one thing – the stock is 0.31” thick, rather than 0.625”.  So my thought was to epoxy two pieces together.  And that works, except despite my best efforts, I end up with these ugly voids you can see.  I’ve tried putting the boards under a press with heavy pressure but there’s always a few spots.

 

Is there a better way/adhesive to do this? 

 

I realize it’d be easier to use 0.625” stock from the outset, but stock of the correct vintage just isn’t available, and it means a lot of me to be using actual boards from the time.

 

Thanks!!
