PROFESSIONAL PC BOARD 
POWER ETCHING SYSTEM
A semi-automatic etching device for use in labs, schools, 
prototype shops and for limited PC board production. 
Reduces etching time to minutes. Air pump agitates etching 
solution for fast, very even etches. Handles up to two 8" x 9" 
PC boards at a time. either single or double sided. The system 
is supplied with air pump, heater for keeping etchant at optimum 
temperature and convenient board holder.
12-700.................$39.95
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.

ER-12................................ $9.95
ETCHING SOLUTION HEATER

Fits in tank and heats solution up to 38 C (100F). Used 
to further reduce etching time. Built-in adjustable thermostat 
controls temperature continuously to 100 F, 120V AC/ 100W Max.

12-702 .......................................$7.95
CONTACT EXPOSURE FRAMES

A contact frame is needed to hold film and PC Boards 
during the exposure. Spring Loaded, Steel Frame comes 
complete with glass, backboard, and complete instruction
  manual.

CIRCUIT-FIX TM PC BOARD TRACE MAKER

The CIRCUIT-FIX system has been designed to allow you 
to cut accurate, burr-free copper foil traces for PC boards for
 the purpose of adding to or repairing a circuit board. CIRCUIT-FIX 
is a handy system weather for prototype modifications or for circuit 
repairs. The system centers on a spring loaded clamp and cutting 
guide that permits excellent trace cutting with a modeling knife. Both 
the knife a sheet of self adhesive copper trace material are included. 
Also included is a sheet of (assorted sizes) pure copper adhesive 
donut pads. The cut trace and donuts are burnished to the board 
and the soldered to component leads.

CIRCUIT-FIX SYSTEM  No. CF-1
Copper Donut refills (308 pcs. assorted) - No. CF-2
Copper Foil refills (2 sheets, 3.25” x 10”) - CF-3

(Note: Copper donuts and foil are 1 oz. copper,.0016” thickness. The copper is passivated to retard corrosion and permit easy soldering.)
