Last year we made one of the group’s largest investments by installing the Ledia direct imaging system in our plant in Eger – Hungary. We can use Ledia to expose inner layers, outer layers and soldermask as well. With the Ledia we can produce PCB’s with tighter tolerances on images and soldermask.
To better optimize all advantages that Direct Imaging of the soldermask with the Ledia has to offer, we needed to change the soldermask to another type. Still from the same supplier, Sun Chemicals, CAWS2708 LDI is better suited for the Ledia’s imaging process.
With this new, professional and reliable soldermask, we can expose our production panels faster than with the previous type. In combination with Direct Imaging, we can also achieve much better results on registration accuracy.
The surface of the new soldermask is perfect for soldering. The matt finish helps with the alignment for placing components and it is better suited for automatic optical inspection after soldering. We are convinced that this soldermask is a modern and user-friendly product.
