Würth Elektronik Demonstrates the
new possibilities of additively applied solder mask, also known as s.mask.
An outstanding innovation is 3D printing in height.
Similar to conventional 3D printing with materials such as PLA or ABS, the solder mask is applied in layers with a thickness of a few μm per layer.
In a certain area, vertical edges of the paint can be realized, but only up to a certain height.
In addition, a certain gradation of the flanks is necessary.
In this way, structure heights of up to 1400 μm (1.4 mm) can be achieved.

From my perspective approach of the digitals soldermask is one of the future "hidden champions" related to 3D printing or "hybrid 3D printing" within electronic design and electronic manufacturing. It's like a "eye opener" or the first step to improve understanding of 3D printing in electronic applicaions.Even if it seems rather unspectacular or even unsexy at first glance. Good work Michael!

Hallo Michael, thank you for publishing! I know you are in contact with different tool providers for this activities - hope you'll keep us updated about that as well as for the FED whitepaper Articles for "AME Classification" Cheers Andi Salomon
