Mike,
That's the reason I posted this today.... I'm also sick of the same old
crap about lasjer jet not being any good... it really is
misinformation...
The other point that I can't abid is them needless search for absolute
blackness in the film... Special this and special that... hog wash...
I use MSOP a lot of the time that's 0.0256" (0.65mm) and have no problem
at all.
With regards to 8 mil..... well I demonstrated today, 10 mil is run of
the mil and 8 mil is just as easy.
I remember a stupid board I was presented with some years ago, it was a
very simple circuit about 10 components and the board was about 4" X 4"
( Deer feeder controller) and the person used 8 mil lines and the
smallest pads ! When they tried to change components of course without a
vacuum driven desoldering tool, pads lifted of and traces got broken.
The golden rule is when you have the space USE IT....
I can do 5 mil if I use Apollo CG7060 film, 3M CG 3300 is only good to
10 mil (8 at a stretch, with some touch up afterwards)
During the years I have trashed two Epson Inkjet (700 dpi) printers
because the nozzles got blocked and I tried everything to devolve the
hardened ink, but nothing worked. At the time Epson offered a head
replacement for $130.... I went out and purchased a HP inkjet printer
instead for less.
If people are dumping Epson Inkjet printers for $5 I'd say good luck to
anyone buying one, perhaps buy two and hope the parts are
interchangeable... There are also good deals on eBay for HP Laser
Jets...
I've only put one new toner in this LaserJet since I purchased it two
years ago, my other one (same type, yes I have 5 printers...) is about 6
months older than that and it's on the third toner.
I buy real HP toners for about $48.... I wonder what Epson's inkjet
cartridges cost... !
