Registration becomes the issue. In my experience, it's just not
worth it, nowadays, unless you're making a HiFi amplifier or
something equally "non-dense". Saving a couple of dollars on
a bare board just doesn't justify the cost (in time)
E.g., why not make your own memory SIMM/DIMMs too? :>
Years ago we had our own etch tank, wave, etc. and *still* ended
up pushing board fab to outside vendors (messy process).
The attraction is, that while the circuit board
houses just don't get
much cheaper than $4 - $5 per board for small boards, the TT can get
down to $.50 - $.75 each by my calculations. Of course, if 75% of
them must be discarded...
From the presentations of this technique on the web, I'm not convinced that
this technique is usable for anything much finer than DIP spacing; e.g.
PQFP. Does anyone have experience to the contrary?
