OK I'll admit it I'm a lurker. In this case I do have some input so here it
is. I made over 50 HDTV distribution amps from scratch, I should have had
the boards made but they were one here and three there so I didn't. My
error. I made a jig for my dremmel flex shaft that mounted it to my router
table. Then I made a platform that fit in my table to square up the double
sided photoresit boards. I used the oversized cutoff wheels and trimmed the
boards to size in under a minute. The only problem I had was the exposed
edge that was less than a millimeter (did this under normal light for
safety). Ended up with am amp that was down .1 Db at 100 MHz, had 21 RCA and
2 3.5 mm jacks as well as an LED. Every board except 1 turned out perfect. I
still use this jig to make one of boards for my personal projects. Due to
the smell I do it in my garage with an air filter and safety glasses.
