Used Cleaning & Drying (Pcb Fabrication)

Overview

Cleaning & Drying systems in PCB fabrication remove flux, residues, and moisture after assembly. These systems include aqueous or solvent cleaners, spray or immersion modules, and hot-air or vacuum dryers designed to protect delicate components and maintain board reliability. They vary by throughput, chemical compatibility, and process control (temperature, conductivity, ultrasonics). Buyers look for stable process recipes, low chemical consumption, and traceability for high-yield production.

FAQ

What should I check when buying a used cleaning & drying system?

Verify process records, chemical compatibility, tank and pump condition, heater and blower functionality, and spare-parts availability. Ask for past maintenance logs and recent consumable replacements.

How do I ensure the system will handle my board throughput and chemistries?

Provide your board sizes, production rate, and cleaning chemistries to the seller. Confirm chamber sizes, cycle times, and materials of construction match your needs.

Are there special shipping rules for these machines?

Yes — machines with residues or onboard chemicals may be classified as hazardous. Drain tanks, purge lines, and obtain correct paperwork. Use experienced heavy-equipment haulers and insure the shipment.

What routine maintenance is needed after purchase?

Regularly replace filters and seals, inspect pumps and heaters, monitor conductivity and heater calibration, and clean nozzles and conveyor paths. Keep a log and stock common spares like seals, pumps, and heaters.
