Ultra High Precision Etching: What If Your Customer Wants a 10 Times Smaller Tolerance Today?
The Electronics Manufacturing Industry and its
designers, our customers, have taken another
step towards higher density integration and
packaging in all market segments such as
automotive, aircraft, aerospace, computers, etc.
The needs for “faster,” “smaller,” and “more
precise” processes are dictating morc stringent
equipment requirements, pushing the physical
limitations to new (smaller) dimensions and
tolerances. The chemical milling industry and its
equipment designers and suppliers had to find
answers to these requirements to continue to
achieve good yields. The entire production chain
– every individual link – has to be upgraded to a
new standard and technology level.
