Surface Modifiers are ultra thin nano coatings that are applied in the range of 0.1-2 microns in thickness. Traditional liquid conformal coatings are applied in the range of 25-75um so they are considerably thicker in nature. How do nano coatings work?
Cleaning of printed circuit board before conformal coating application helps but may not be essential. However, the cleanliness of the circuit can be crucial for both the short-term production process and the long-term reliability of the circuit. Why clean a
Inspection of conformal coated circuit boards is a critical process that should be carried out on completion of the coating process. However, it is often a neglected stage of the conformal coating production line. The International standards such as IPC A 610
Batch spraying is a simple method to apply conformal coating to a circuit board in a cost effective way. At its most simplest you require Spray gun and compressed air The conformal coating material diluted to the right viscosity A suitable spray
