THE FINAL RESULT EXCLUSIVELY DEPENDS ON THE CARE TAKEN DURING EACH OPERATION
(please read these instructions before making your first circuit)
EXPOSURE
-
Remove the adhesive protection from your C.I.F. positive light-sensitive plate.
Place our film or original drawing on emulsion layer (Pay special attention to placement ; component side or
-
track side).
-
Place the set (film + board) on your exposure unit.
Expose your board :
-
from 1' to 2'3'' when using a film or an inactinic grid
from 2'30'' to 4' when using a plant tracing paper. (make a test to calibrate your exposure unit).
DEVELOPMENT
Prepare the development into a tray
Pour the contents of CIF bag into the tray and add the quantity of water required (at 18° minimum).
Wait for a complete dissolution of the crystals.
Immediately after exposure, put the board into the developer and shake.
The photosensitive resin which has been exposed should disappear in less than 2 minutes. If development has
not been totally carried out, please refer to the table at the end of the notice).
If the plate is not immediately etched, rinse it with running water.
ETCHING
To avoid a waste of time, heat your etching machine before exposing your circuit.
Put your circuit into the etching tank.
Etching agent will corrode the copper which is not protected by resin.
Etching time (with new ferric chloride) : from 45'' to 2' into spray etching machine, from 5' to 8 ' into air pulsed
etching machine and 8' into foam machine) 20' into a tank.
When etching time has doubled, change ferric chloride.Rinse.
RESIN REMOVAL
With buffer or C.I.F.stripper.
Resin can be left during drilling to protect copper.
Etched board can be reexposed and resin destroyed with U.V. : plunge the board into the developer.
Your circuit is finished (you can either tin or varnish)
