Operationally, conformal coatings are applied to the surface of PCBs and related electrical components, to insulate and protect them during use. Coatings improve PCBs’ performance under any circumstances, but are especially valuable for their functional tolerance to harsher working environments.Read More
Parylene Coating Blog by Diamond-MT
Parylene and acrylic resins are both conformal coatings. Most of the similarities stop there. Because their properties vary so much, they have their own unique uses and capabilities.
Depending on your application, choosing to use conformal coating equipment can be a very wise choice for maximum efficiency. I would recommend use of the conformal coating process decision worksheet to determine your coating needs and whether you should outsource conformal coating prior to purchasing a machine.
How to get Repeatable Conformal Coating Thickness
Measuring your conformal coating thickness is one thing, however making it a reliable and repeatable thickness is something else all together. There are three main ways of conformal coating application where a repeatable thickness can be obtained, however, a fair degree of training and skills are needed to achieve this.
