[sdiy] For breadboard lovers...

[Jerry Gray-Eskue]

I have been using the PnP Blue also, and progressively getting better
results. The key seems to be using an Iron (my laminator is not the correct
temperature) and getting the temperature just right.

I am using a Brother laser printer that has some control settings I use when
printing the transfer, they are :
(1) Improve Print Quality - Reduce Paper Curl - this is lower fuser heat
	Running PnP through at normal heat causes the PnP to distort from flat.
(2) Density Adjustment - Set to MAX - this increases the amount of toner on
the paper.

I have seen photos on the web of PnP Blue being used for very fine pitch SMT
devices, and I think at this point the quality I am getting would be good
enough for SMT. It is easy to tell if the quality is good enough before the
etch by looking at the resist under magnification.

I was thinking of DIP chips, but I probably could etch that fine pitch.  The
problem isn't the etching.  The problem is the transfering of the design to
the board with PnP blue, which (in my experience) never works perfectly.
