Saponifier Delivery Set Up
Introduction Printed Circuit Boards (PCB) processed using rosin based flux require a saponifier
in the cleaning process. The ratio of saponifier to water in the wash module has a
direct affect on the quality of PCB cleaning.
Using detergent injection, and a closed loop system between the prewash and
wash offers a cost effective and efficient cleaning option. The detergent injector
automatically supplies a predetermined amount of saponifier to the wash water
each time the tank is filled from an empty state or when water is added to the
tank to maintain the operating level. This helps keep the concentration levels
stable and maximizes PCB cleaning.
This process is further enhanced when using level two(2) or three (3) chemical
isolation and a prewash-wash isolation process. Refer to the Aquastorm 200™
Operation Manual for more details on the chemical isolation module and its
operation.
The detergent injector connects in-line with the wash module rear plumbing feed
inlet. The inlet side of the injector has a length of vinyl tubing attached. A
stainless steel strainer is installed at the other end of the vinyl tubing.
Safety To ensure personal safety and avoid equipment damage observe the following:
CAUTION
A qualified maintenance person or an Electrovert service person should perform
injector set up steps.
CAUTION
Arrange for two (2) people to move or lift the storage tank to avoid possible
injury.
ATTENTION
The injection rate adjusts from 90–2700 C
3
/min (3–100 oz./min) depending on
the viscosity of the detergent used. After initial adjustment, the metering screw
should not require further adjustment since the injection rate remains constant,
regardless of any pressure change. When using a different detergent with a
different viscosity re-adjust the metering screw to meet the new requirements.
