Plug Via Process Requirements for Printed Circuit Board new design pcb solder mask machine cup mask making machine

Many printed circuit board designs are seen with vias tented via primary mask. This could be a result of a lack of reliability data. Pros The pros to primary LPI solder mask tenting vias is it is only a one step application. Cons Via tenting cannot be guaranteed with LPI mask. There are three common methods of applying LPI mask.PrintedCircuits Biomimetics and Dextrous Manipulation Lab1) It may be much cheaper to pattern your circuit design and order just one board with many. You will then want to machine them apart from one another. When cutting fiberglass, use a resperator or dust mask, and safety glasses.
