Businesses must weigh all these factors when determining whether a worker is an employee or independent contractor. Some factors may indicate that the worker is an employee, while other factors indicate that the worker is an independent contractor.
Conformal coating material is a thin polymeric film which âconformsâ to the contours of a printed circuit board to protect the board's components.he selection of conformal coating material is a crucial factor that needs to be considered carefully and in relation to the application method. The wrong selection can not only affect the long term reliability of the circuit board but can cause massive difficulties with both processing and costs.
They are not designed to be a total sealant. Conformal coatings are a breathable protective layer that will protect against the particular environment requirement but will also allow any moisture trapped in the circuit board to escape. The particular advantages of conformal coatings can be summarized as follows: 1  Insulating properties allow a reduction in PCB conductor spacing of over 80%. 2  Can help eliminate the need for complex, sophisticated enclosures. 3  Light weight. 4  Completely protect the assembly against chemical and corrosive attack.
