Time is money, especially for the busy SMT production line. Although PCBA protection is a later process, the efficiency and effectiveness directly affect the delivery cycle and yield of PCBA. This is especially true for mass and multi variety production lines. PCBA needs to be coated for many times in order to meet the protection requirements. If you want to get a thicker coating, the conformal coating needs to be obtained by applying two thinner coatings, and the second layer must be applied after the first layer is fully cured. It takes time to cure completely. The digital packaging process is different. UV-Led is cured with follow-up while spraying, and the second layer can be sprayed immediately with controllable thickness.

PCBA packaging protection is completed by a more accurate and simplified process, which does not need to wait for curing and occupy the curing site. This is especially true for a large number of circuit boards that need protection. "Some of these batches may occupy the workshop for several days, so it is very important to save a few minutes per board."

Choosing a reliable process is also an improvement to the quality of the product.
