1. Preface

With this instruction we would like to give an over-

view   about   structure,   function   and   operation   of 

the spray etching machine Jet 34d. Please read 

the following text carefully and pay increased at-

tention to the references on job safety and set-up. 

Deposit   this instruction at a safe place. It con-

tains   information   on   maintenance   or   cleaning, 

which you will need later on as well. 
If you encounter a problem which is not answered 

by this manual, please contact us by phone or by 

mail. This will enable us to give specific advice 

and analyze malfunction if this ever occurs.

The   machines   are   manufactured   by   Bungard 

Elektronik, Rilkestraße 1, D-51570 Windeck and 

brought   into   circulation   in   the   EEC-MEMBER 

countries   by   the   respective   retailers/contracting 

parties. 
Operation areas: 
aqueous-alkaline or sour etching of printed cir-

cuit boards. 
Developing   of   positive   or   negative   working, 

aqueous-alkalinely   processable   fotoresists   or 

laminates (if necessary add antifoaming agents).

3. Safety Instructions

The machines are intended for the chemico-phys-

ical treatment of printed circuit boards. 
The machines are not intended to be integrated 

or connected with other machines or plants. They 

may be operated only in appropriate areas and 

run only by qualified technical personnel. Children 

and domestic animals are to be kept away! 

Electrical connection 

The   machine   is   manufactured   using   certified 

parts according to the usual guidelines for elec-

trical   security.   This   does   not   release   the   user 

however   of   his  duty  to   exercise   diligence   while 

handling electrically operated devices.
