Re: Wire connections to SMT PCBs?

Stefan,

It seems you have had at least one bad experience at some point with 
traces coming off...

With the older and/or cheaper bakelite type boards this can be a 
problem, but I sure haven't seen it with any of the glass-epoxy types.

At any rate, if this is a concern, use of some epoxy which can adhere 
to the bare parts of the board between the traces will deal with it. 
And provide a conformal coating at the same time...
