Go For Additive Solder Mask Manufacturing
Save time, material and production costs.
Only add material where it's required
That's what additive solder mask manufacturing is all about and that's what makes inkjet printing of solder mask so beneficial. Inkjet printing, being an additive process, means less process steps compared to traditional solder mask coating or Laser Direct Imaging (LDI). Photo and development process are eliminated as is the need for full surface flooding. This speeds up production while reducing waste, material and energy consumption.

Inkjet Printing Process
How does it work?
Preparation
Outside of inkjet printing tool
- Surface pre-treatment of choice: Pumice or
µEtch + Anti-tarnish
Solder mask coating
Using JETxSM
- Loading and board reading
- Alignment on 4 or more points
- Computation of image specific to board deformation and serialization
- UV Bump
- Unloading
Post coating
Outside of inkjet printing tool
- Legend printing
- Baking: 60 min at 150 º C
- Metal finishing (HASL, ENIG, Sn/Ag immersion …)

Boost Your PCB Manufacturing with JETxSM FE Software
How can JETxSM FE software improve additive manufacturing in solder mask application, even without operator skill and experience?
Take full advantage of additive manufacturing in solder mask application with the software package “JETxSM FE”. It bundles all necessary expertise on functional inkjet printing. Thus, printing jobs created by JETxSM FE provide the PCB manufacturer with supreme control on solder mask coating parameters like feature size and thickness. The JETxSM FE operates according to computer-aided manufacturing (CAM) principles, making its printing jobs directly available to the tool on the manufacturing floor. The specific printing job for each board is loaded and successfully printed. This ensures the best possible result even without specific operator skill and experience.
