TECHNOLOGY THURSDAY: How do we Expose the Soldermask during Production?

Today TECHNOLOGY THURSDAY  takes you back to 2017. We have invested in a spray coater machine for soldermask and a direct imaging machine to expose the soldermask in both our plants (Hungary and Germany). This enables finer soldermask structures and better registration of the soldermask to the copper image. One of the biggest improvements of the PCB that bears its fruits during the assembly as it avoids soldering shorts and rework.
