HZO Coating Process
1 Pre-Production
- Inspection for quality standards and control for product tracking.
- Assembly preparation takes place.
- Masking of areas where protection is not needed can be fully automated.
2 Production
- HZO raw material added to vaporizer and sublimated from solid to vapor form.
- Chemical is heated to a high temperature in a pyrolyzer, which "cracks" the raw material into an activated monomer.
- At room temperature in the coating chamber, vapor forms a uniform, thin-film polymer barrier around the PCBs.
