Coating range of servicesOur range of services for subcontract coating outsourcing for North America, Europe and Asia includes a huge selection of coating materials such as conformal coatings, Parylene and fluoropolymer Nano-coatings.

Our range of services for subcontract coating outsourcing for North America, Europe and Asia includes a huge selection of coating materials and application methods.

Due to our many options in coating this allows you to choose the right material and coating process from our range of services to suit your product.

Material range

Rather than you choose from only a limited amount of coatings here at SCH we provide a wide range of services across our own and partner sites for many different high performance materials and coatings.

The subcontract coating services we can offer include:

  • Conformal coatings
  • Parylene
  • Fluoropolymer Nano coatings
  • RFI / EMI Shielding
  • Chemical Vapour Deposition (CVD)
  • Atomic Layer Deposition (ALD)
  • Ceramic & metallic coatings
  • Hydrophobic and hydrophillic films
  • High temperature protective materials
  • RTV silicones, encapsulation and potting

Also, we are happy to use a customer specified product or recommend a suitable product based upon your needs. Further, all materials are applied to customers required specifications unless support and advice requested.

Application systems

SCH Technologies and our partner companies use a wide range of application methods to apply the coatings because we do not want to limit your options.

These techniques include:

  • Semi automated dipping using both vertical and horizontal methods for conformal coatings and fluoropolymer Nano-coatings
  • Robotic selective spraying machines using proprietary systems
  • Batch spraying using state of the art HVLP gun technology and conformal coating spray booths
  • Encapsulation and potting using Injection systems and metered pump technologies
  • Vapour Depositions for application of coatings such as Parylene and other thin film technologies

Therefore, whatever your coating requirement we will have an application method to suit you due to our wide range of sites and facilities

Process control, inspection and measurement

SCH technologies use a range of Conformal coating inspection processes in their coating services

The control of the whole process when applying all coating materials can be critical to a successful solution. Therefore, process control is very important.

First of all the cleanliness of the printed circuit board (PCB) can be critical. 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.

Further, 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.

In addition, 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 normally critical along with performance tests such as adhesion measurements to test the coating quality and thickness measurement of the conformal coatings.
