Given the variety of soldermask configurations Lab Circuits has to process, the company’s approach is to unify mask-treatment criteria to focus on a final result of high quality and functionality, both in manufacturing and in the subsequent assembly. The standard parameters Lab Circuits works with are as tight as possible in order to make this purpose feasible.
The purpose of this document is to provide knowledge about the process and bring the results offered by Lab Circuits as close as possible to our customers.

Section 1.2 of the IPC 6011 standard for generic specification on the performance of printed circuits sets forth the classification criteria for printed circuit boards according to their degree of functionality and performance. According to these criteria, these are grouped into three classes:
 Class 1: General and consumer electronics products.
 Class 2: Professional electronics products.
 Class 3: High performance and reliability electronics products. Printed circuit boards for avionics are given the classification 3/A.
