Conformal coating and encapsulation offers protection for products which operate in challenging environments, or require a security seal. At CT Production these processes are carried out using fully automatic and semi-automatic equipment delivering cost effective, accurate and consistent results, plus a safer and cleaner environment.
Conformal Coating: The PVA 650 automatic conformal coating machine is highly accurate, using fine spray patterns, thus eliminating the need for masking. The preferred material is Humiseal UV40, cured in a microwave UV oven, dry to touch within seconds of application.
Encapsulation: PCBs etc are encapsulated in resin to protect against vibration, shock, liquid or for intrinsic safety. Encapsulation using Robnor equipment provides an automatically self-metered encapsulation process.
Liquid dispensing: The Fisnar F4200N liquid dispensing robot enables adhesives and other liquid materials to be applied automatically for repeat operations. It can also be used to apply liquid sealant or gaskets of any shape, for coating, or for potting and filling (see News item)
Examples of conformally coated or potted products include aerospace and nautical products, furnace monitoring instruments, gas detectors, door entry systems, high volume leisure products requiring vibration and strain relief and IPR protection.
