Hi All and especially Juergen....
Heating etchant is something I normally do with a sink of hot water
into which I empty a boiling kettle. Place the bottle of etchant in
the sink, leave it ten minutes and it is hot. Admittedly I've got a
heated bubble etcher so I only do this to pump some heat into the
system before I start, like decide to do boards, put kettle on, run
tap, put bottle in sink, make cup of tea, pour kettle into sink, get
rest of gear out, UV first board, put first board into developer, pour
etchant into bubble tank and turn heater to max, run second board in
UV, first board into etcher, second board in developer (it takes two
eurocards), third board into UV, keep a check on the first board, when
it's nearly done, then third board into developer, fourth board into
UV, first board out, third board into etch....etc etc... I reckon to
have the first board out inside half an hour and then a board approx
every fifteen minutes after that......
The bubble tank came from Maplins, costs about 70 UKP and was the best
Xmas present I've ever got....
