Electronic circuit production employs:
1. Coating a photoresist on the metal
surface
2. Exposing the photoresist with light of the
proper wavelength for the correct time
3. Developing the image
4. Etching the metal pattern
5. Stripping the photoresist

Electronic Circuit Production:
1. The traditional process produced waste
and scrap caused by "drag-out" of
chemicals from one tank to the next
2. Large volumes of evaporative waste were
also produced from the open tank design
used for, etching, rinsing and drying the
circuit components.

Electronic Circuit Production:
3. This more efficient and less polluting
process supplanted the older
technology for many of IBM's
circuited products.

Environmental Benefits
7. Rinse waters reduced by 75 percent
or 30,000 tons per year
8. Use of "fluid head" consumes only
one-half gallon per minute versus the
3 to 5 gallon per minute consumption

Benefits
9. Plating bath efficiency improved by
20 percent, primarily as a result of
eliminating vertical racks and
associate rack stripping steps. The
result is less drag out and reduced
plating on fixtures.

Environmental Benefits
10. Efficiency is gained across each
chemical process including cleaners
microetch, sulfuric acid predip,
activator baths, reducer bath,
electroless copper bath, acid dip,
and acid copper baths.

Environmental Benefits
12. Reuse of spent micro etch bath for
maintenance reduced waste by 55
tons per year.
13. The spent persulfate solution from
the microetch station is saved for
reuse

Environmental Benefits
14. Toxicity reductions achieved by
converting a hazardous/corrosive
activator bath to a neutral activator
chemistry by electrifying a plating
allowing use of lower concentrations
of chemicals

Environmental Benefits
15. Energy savings of more than
500,000
kilowatt hours were realized as a
result of conveyer efficiency
compared to the old hoist system and
reduced process ventilation for the
enclosed process design

Environmental Benefits
16. Overall process efficiency was
improved by using chemical totes
instead of 55-gallon drums, realizing
a savings of more than $20,000
annually

Summary
1. As Electronic circuitry density
increases, DI Water Rinsing needs to
increase by 2 orders of magnitude to
meet product reliability requirements.

Summary
2. Developed DI water rinsing head
(fluid head) which improved rinsing
quality by one order of magnitude and
reduced DI water consumption by two
orders of magnitude resulting in a US
Patent.

Summary
3. This was a brain-storm by myself, Jim
Veasaw and an operator. We
changed the rinsing from spraying to
cross-product.
4. This significantly improved rinsing
and product reliability.
