What is resist
A photo resist is a chemical product that, under the influence of UV light,
changes its chemical nature.
Resist without UV: is washed away during resist development
Resist with UV:
is NOT washed away during resist development protects the copper in the etch batch is stripped away after etching
Remark:
1 Etch resist: print & etch of inner layers
2 Plating resist: print, plate & etch of outer layers

What is resist
Liquid photo resist (20%)• Curtain, roller- or spray coated• Thickness: 5 - 20µm• Pro: high resolution• Contra: dust inclusions and chemical sensitivity
Dry photo resist (80%)• Cold, hot or wet laminated• Thickness: 25 - 75µm• Pro: high yield and good tenting• Contra: line width
Tenting: Via’s must be tented to avoid resist getting in the via

Traditional resist printing
Workflow:• Design• Image and develop film, check• Coat, laminate resist• Image resist• If laminated: peel cover layer• Develop resist• Etch• Strip
Working with resist is:• A time consuming process step• Expensive• Fixed data• Ecological unfriendly

Inkjet resist printing
Principle:• apply etch / plating resist• directly on the panel• using a set of Inkjet nozzles mounted on a XY table• ie without the use of a phototool or screen
Workflow:• Design• Print (with pin curing)• Curing (thermal and/or UV)• Etch• Strip

Inkjet resit printing
Advantages:• Reduce cost
- no phototool, less production steps- shorter production cycle, higher yields
• Registration panel per panel / distortion compensation- front-to-back- outer layer to inner layer
• Design changes & variable data per board• Fast (no set up)• Ecology

Quid May 2013
R&D project is in progress
Jetability and etch resistance: OK
Stripability: concepts are tested
Planning• One ER fieldtest in operation by end 2013• Proliferation of ER in 2014• Concept study PR
