BEFORE CLEANING AFTER CLEANING

2. Major EMS factories are beginning to understand that their
SMT Assembly is not complete without a Pneumatic Stencil
Cleaner. Certain stencil cleaners can help cut down overall
costs like labor costs, printing errors, and factory and
environmental hazards. We have found that often times SMT
Factory Owners and CEOs tend to overlook the costs within
the stencil cleaning process that affect many factors down the
operation line. It is not just the cost of the machine being
purchased, it is the overall cleaning system that you are
investing in which has an effect on many different areas and
should be addressed when considering your best stencil
cleaning method.
The Pneumatic Stencil Cleaner can be used for various
stencils and misprinted PCBs, the combination of features
offered by our S-1688 make it a unique and truly automatic
stencil cleaner, allowing the operator to walk away from the
process without worry. Normally, stencil cleaners require
manual positioning and movement from experienced operators
to ensure consistent cleaning. The S-1688, from start to finish,
is a closed cleaning system that does not require experienced
operators or any repositioning. It is the easiest solution for
ease of operation, fire safety, chemical safety, and the
environment.
The S-1688 frees operators by performing the following
operations automatically: combining a specifically shaped
ultrasonic cleaning chamber, continuously filtering the
cleaning bath, automatic indication of the liquid level and filter
status, and automatic loading/unloading of the stencil. Its
integrated loading arm ensures that every stencil is positioned
precisely the same way inside the cleaning tank and that it is
withdrawn from the cleaning chemicals as soon as the cycle is
finished. Its filtration system continuously removes solids
from the cleaning liquid, often maintaining the cleaning
effectiveness of the medium for up to a year or longer
(depending on usage, of course).

3. There are three main pollution sources to consider
when dealing with Stencil Cleaning Equipment for
your PCBA. They include gaseous emissions,
wastewater, and solid emissions. Depending on
the regulations of the location you conduct
manufacturing, the quantity of the emissions, and
any fines or penalties associated with these
emissions, we recommend learning about
environmental pitfalls and avoiding them
altogether.

The environmental pitfalls you can avoid by choosing the
S-1688 Pneumatic Stencil Cleaner:
Air Pollution:
Ozone Depleting Substances
Climate Change Contributing Substances
Odors
Solid Waste:
Heavy metal cations (notably lead,
tin and copper)
All leachable toxic materials up to 100 years in
authorized discharge conditions
Used solvent
Waste Water Pollution:
Heavy metal cations (notably lead, tin and copper)
Anions (notably phosphates, nitrites and sulfates)
Complexing/chelating agents (notably EDTA salts and
ammonium/amine compounds
PH (acid or base condition)
COD/BOD
Other (temperature, solid matter, suspended matter,
Toxicity to aqueous life before and after biodegradation
surface tension modifiers, etc.)

4. Stencil Cleaning Safety
S O U T H E R N M A C H I N E R Y • S M T H E L P . C O M | 3
Manual Stencil Cleaning poses many safety hazards to people, property, and productivity. The
highly flammable, and extremely concentrated solutions that are typical of stencil cleaning
solutions pose a risk to operators assigned to this laborious task. In addition, machines that plug
into the electrical outlet pose a fire and detonation risk.
The Pneumatic Stencil Cleaner S-1688 offers a no-rinse, aqueous cleaning agents for 100% closed
loop process, for conformity to present and future economic and environmental operating
requirements.The operator can start the cycle and walk away from the cleaning operation. Also, its
compact footprint, integrated castors, and trivial connection requirements-its only connection is to
a 240-volt outlet, with no water or drainage requirements make it very flexible.
The pneumatic design of the S-1688 machine adopts a fully pneumatic control wash, to clean the
stencil type circuit board and can effectively remove the solder paste and flux residue. It is driven
by the pneumatic logic control and efficient, fast, safe is cleaning the stencil current and
recommended method, using rotating efficient atomization spray arms, four heavy solution filtration
cycle use, simple maintenance, all in a stainless steel body that guarantees the life span.

We hold ourselves and our machinery to a higher
standard. Emerging green technologies (EGTs)
create changes with product design and
automation which increase efficiencies for many
categories including costs, materials, time, and the
environment. Current technologies have updated to
recycle and reclaim methods that used to simply be
considered waste water. This is no longer the only
option, nor the best option.
In every capacity, your factory should aim at
moving toward green practices that return on your
investment for the long-term. When resources are
limited, growth is limited; think about the future of
your business when considering how you can
implement best practices and technologies for your
factory's future.
There are a number of different stencil cleaning
systems, but choosing the best solution for your
assembly will greatly affect your factory's overall
productivity.
