Conformal coating subcontract services
The SCH Technologies Group operate across North America, Europe and Asia and offer both liquid and Parylene conformal coating services.
We provide many methods of conformal coating application techniques, applying different conformal coating materials (liquid and parylene), RFI shielding lacquers, varnishes, encapsulate and potting compounds.
The diverse materials used require a range of coating techniques and a high level of process control which we apply through our ISO 9000 system.
The reason we give the best results for a customer are our
- Full range of coating application systems
- Our process controls, inspection and measurement techniques
- Our knowledge of coatings of all different types
Coating application systems
SCH Technologies and our partner companies use a range of conformal coating service application methods to apply the conformal coating materials, RFI shielding lacquers, varnishes, encapsulate and potting compounds.
These techniques include:
- Dipping: Semi automated dipping using both vertical and horizontal methods,
- Selective Robot: Robotic selective spraying machines using proprietary systems
- Batch Spraying: Using state of the art HVLP gun technology and conformal coating spray booths
- Vapour Deposition: For application of Parylene coatings and other thin film technologies (ALD, MVD, CVD).
Coating application process control
The control of the whole coating process when applying materials like conformal coatings, RFI shielding lacquers and potting compounds is critical to a successful solution.
The first factor that can be critical is the cleanliness of the printed circuit board (PCB). The PCB may require some cleaning method to improve the coating finish such as an aqueous cleaning process and test methods such as ionic contamination testing and dyne surface energy pens can be used to help measure and control the process.
Control of process application factors like viscosity, temperature and humidity also ensure that the best results are achieved for the material applied and the results on the printed circuit board.
Conformal coating inspection and process measurement
Once applied, the curing and drying of conformal coatings and other materials are important areas and control of the infrared / convection ovens and ultraviolet (UV) cure conveyors is critical.
Finally inspection processes are critical and include automated conformal coating inspection for high volume, adhesion measurements to test the coating quality and thickness measurement of the conformal coatings.
SCH Technologies and our partners use a range of proprietary conformal coatings, parylenes, RFI Shielding lacquers, paints, RTV silicones, encapsulates and potting compounds.
We are happy to use a customer specified product or recommend a suitable product based upon your needs.
All SCH Technologies materials are applied to customers required specifications unless support and advice requested.
