n.jet soldermask Technical Information

Inkjet Printing of Solder Mask ... in Solder Mask Production Replacing subtractive process chains with additive process steps in electronics production has been one of the founding ideas of Notion Systems. It increases production efficiency and reduces waste. On top of this, the n.jet electronics series increase process stability and enables new features in today’s electronics production. This pushes the limits of current production tech- nology for rigid and flexible circuitry on any substrate material. Image shows 3 mil dams: Edge coverage of traces can be adjusted. CURRENT PROCESS Minimum dam size achievable is < 2 mil (40 microns). For high copper thickness, only trace edges need additional ink.
