8 mil tracks with JetStar film

2006-01-25 by leon_heller

I just made a board using 8 mil tracks with the JetStar Premium film
sample that Mega sent me. They came out very well with no over-etching
- all the tracks are visually the same width. There are definitely no
breaks.

A minor problem was caused by the film being slightly thicker than the
standard JetStar film, and a little ink got smeared on in one place,
because I use an ordinary piece of paper as a carrier, making the
whole thing a bit too thick. I'll have to remove a couple of small
dots of copper that have caused shorts.

The board has an MSP430F1232, a couple of buttons, an LED, and a Spark
Fun Electronics MiRF module (nRF2401A), all powered by a Li coin cell.
It's mostly SMT.

Leon
