Inspecting Conformal Coating on PCBs – Using the IB100 Conformal Coating Inspection Booth

The IB100 conformal coating inspection booth is an ideal work station for operators to inspect & finish circuit boards which have been conformal coated.

Fitted with dual UVA lamps behind a safety screen to allow solvents to be used safely in the booth, the IB100 offers 36W of ultraviolet light for maximum visual inspection & finishing performance without compromise to operator safety in operation.

Conformal coating Inspection – A range of systems for inspecting conformal coatings on PCBs

SCH Technologies design and manufacture a range of purpose-built, compact and coordinated UV inspection & finishing booths for conformal coating inspection.

These systems are used in SCH’s coating service and have been optimised to offer the best inspection & finishing performance without compromise to health & safety, coupled with ergonomic design to minimise operator fatigue.

An important point in conformal coating inspection & finishing is to creat the optimum environment where an opertor can easily inspect coated circuit boards without fatigue to body or eyes, provide the highest quality results for the conformal coating process and keep the operator safe from the harmful effects of solvents.

Spray Conformal Coating successfully with the CB100 Conformal Coating Spray Booth

The CB100 Conformal Coating Spray Booth is a free standing, purpose built system, which can be made to customer’s size and specification requirements. The CB100 is designed for safe application of conformal coatings whilst spraying, without compromise to performance, quality or throughput.

Spraying Conformal Coating

Conformal coating spray application is one of the widest used methods in the electronics industry. Methods include conformal coating aerosols, spray booths and selective spray robots.

Conformal Coating Aerosols are suitable for very low volume application where invsetment in equipment is prohibitve. Conformal Coating Spray booths become economic when volume use of aerosols reach > 10 aerosols per month giving a return on investment relatively quickly. Selective spray robots may become cost effective where volume is high and detailed and compelx masking is required.
