- Pre-wash section: Soften and decrease the biscosity of flux or dusts.
- Wash1 & wash2 sections: Wash flux and dusts particles on PCBA.
- Chemical isolation section: Isolation liquid between wash and DI water pre-rinse section.
- Pre-rinse section: DI water spray to take off liquid on PCBA(substrate).
- Rinse section: DI water further spray to take off liquid and ion contamination on PCBA.
- Final rinse section: Fresh DI water spray to take more ion contamination on PCBA.
- Air blow section: Blow off DI water on PCBA.
- Hot air dry section: Hot air blow to make moisture on PCBA into vapor and make it dry.
