Printed Circuit Board Ultrapure Water System – ST-LPW48 Series provides deionized or ultrapure water for circuit-board washing, plating rinses and process preparation. Reducing dissolved salts in rinse water helps avoid carrying unwanted ionic residue onto the board or into the next process bath.
Ion exchange, double-pass RO and RO with EDI are alternative treatment routes. Their regeneration, membrane and operating arrangements differ, so the choice follows incoming water and the board process instead of assuming every installation needs the same train.
FEATURES AND BENEFITS
How it helps
Feed preparation before treatment
Media and carbon filtration, softening and precision filtration prepare the incoming supply for the selected main treatment route.
Coordinated pumping and storage
Tank-level and pump-pressure protection manage the transfer from production and storage to the board line.
APPLICATION ENVIRONMENTS
Where this configuration is used
Printed Circuit Board Ultrapure Water production
Supplies controlled water for board washing, plating rinses and process preparation.
Electronic materials
Supports compatible material, component and tooling rinses where dissolved ions can affect yield.
Precision cleaning
Provides the selected grade for final rinsing where residues, particles or ionic background must be limited.
SELECTION GUIDANCE
Choosing the configuration
Treatment route and rinse schedule
Compare resin regeneration for ion exchange with membrane servicing for double-pass RO and the electrical supply needed by RO with EDI. Choose the route that fits the incoming water and the board line’s operating schedule.
