PC BOARD MAKING CHEMICALS, ACCESSORIES
NEGATIVE ACTING LIQUID
PHOTO RESIST
NEGATIVE RESIST DEVELOPER
A liquid, spray-on coating in its own spray bottle.
When a coated board is exposed to UV light, it is
then developed in the ER-8 liquid developer. A
remaining etch resist will protect the copper from
an etchant bath, thus producing your circuit.
Negative acting. Coats approx. 1700 sq. inches.
May be flow coated or brushed.
4 oz. Bottle (Includes Sprayer)-No. ER71
This developer will develop the ER-71
Negative Acting Resist; resist areas not
hardened via UV light are dissolved
away. UV hardened areas remain to
resist the etchant.
16 oz. Can Developer-No. ER8
PC BOARD ETCHING SOLUTION
(LIQUID FERRIC CHLORIDE)
12-2038
Quart (32 oz)
12-2039
Gallon (128 oz)
DRY CONCENTRATE ETCHANT
(FERRIC CHLORIDE)
Ferric Chloride is the best choice for etch-
ing copper PC boards. Datak supplies
FeCl in a dry, powder form and the user
must add it to water to make the etching
solutions. The 1/4 lb. package produces 1 pint which will etch
approx. 200 sq. inches of standard copper board.
1/4 lb. FeCl etchant powder-No. ER3
1 lb. FeCl etchant powder-No. ER21
2 lb. FeCl etchant powder-No. ER22
POWER ETCH PUMP
The etch pump and distributor tubing may be used to accelerate
etching and free you from some of the constant agitating of the etch
solution. Bubbles provide both agitation and also some oxygen
which inhances the process

TINNIT KIT
TM
This handy kit contains package of No. ER-18 Tinnit
(sufficient to make 1 pint and plating 600 sq. in. of cop-
per), plastic tray (8” x 6” x 2”), 16 oz. plastic bottle for
storing tinnit between uses and tool for handling P.C.
board during tinning process.
No.12-800
TINNIT TIN PLATE
Tinnit
will plate a copper clad board with a bright tin plate
TM
TM
approx. .0004” thick. Enhances solderability, resists oxidation. Also use
on card edge contact fingers. Supplied as a dry concentrate; just add
water. One pint plates up to 600 sq. inches of copper. May be used to
plate some other metals such as brass, bronze, iron; anything more
active than tin.
Plating is complete in about 10 minutes in a fresh solution.
Tinnit
TM
is supplied as a dry mixture with indefinite shelf life.
When mixed with water, the solution has
approximately a 2 month life.
TINNIT 1 Pint Size - No. ER18
TINNIT 1/2 Gallon Size - No. ER181
This Ferric Chloride is one of the most popu-
lar and safest etching materials for copper
clad boards available. A quart of etching
solution will etch approximately 960 square
inches of PC board.
Caution: use only with plastic or glass trays
