If you intend to use BROTHER printers, keep in mind that Brother toners
have higher melting temperature than other toners. It may be difficult
to transfer image made by BROTHER printer. I was able to make a transfer
using BROTHER printer, but only by hand and iron pressing for 1-2 minutes.
GBC laminator did not transfer even smallest piece of image made by
BROTHER printer. If you have BROTHER, first experiment several times or
get different laser printer, there are very inexpensive models out there.
PnP Blue produces high quality prototype PCB resist layouts making your
design ready to etch. PnP Blue is a Mylar (Polyester) backed material
in which several layers of release agents and resist coatings are applied.
An image is printed or photocopied onto this film, using a laser printer
or photocopier (dry toner based), and subsequently ironed or pressed
onto a cleaned copper clad board. The image area applied to the film
is subsequently transferred to the copper board, along with the high
quality resist (blue). The film is removed and resulting board is ready
to etch in ferric chloride.
How to
Photocopy or Laser Print circuit image onto the dull side (emulsion)
of Press-n-Peel Image Transfer Film.
Prepare: Clothes Iron, Steel Wool #00 (or SOS/Brillo with all the soap
washed out), Packaging Tape,Photocopy or Laser Printed Circuit Image,
& Directions
Cut Press-n-Peel, leaving a 1/4" border around the circuit image.
Cut board to size. Clean copper board with steel wool, S.O.S. or Brillo
pads. Rinse cleaned board with soap and water. Be sure to remove all
soap residue. Dry thoroughly with lint-free cloth. Be sure to scrape
any burrs that appear on the edge of the board that may have resulted
from the cutting/shearing process. Burrs tend to keep the iron from
making solid contact with the Press-n-Peel Film
Place Press-n-Peel with image face down onto clean copper board. Iron
the Press-n-Peel Film to the board a peice of plain paper between the
iron and the film to reduce friction. Temperature setting on the iron
is critical, and dependant upon your laser printer or photocopier.
Suggested starting temperature is 275-325 degrees F. Iron setting
is generally "polyester". Iron temperatures vary. Iron until
board has completely and fully reached the temperature of the iron.
Time varies with the size and thickness of the board. Generally this
is 1.5 to 10 min. DO NOT USE THE STEAM SETTING!
Quench the board/film combination under cold running water. Peel the
film off.
To remove small "fills" in between traces and "filled
donuts", cover the imaged copper board with clear packing tape,
and then remove. This will pull all unwanted filled areas off the
board.
After removing "fills", trim the board (if necessary) to
the final size. Wash the board in soap & water before etching to
remove surface oxidation. Etch with Ferric Chloride (Note: Techniks
does not sell PCB etching supplies -- available through local
electronic supply stores & Radio Shack)
Using steel wool, scrub the Press-n-Peel image off as to reveal copper
traces. This is best done under running water. Suggestion: Do not do
this until your ready to drill and populate the board. The Press-n-Peel
transfer resist protects the board from oxidation.
