ZQ-6800I Inline PCBA Cleaning Machine

Quick Overview

ZQ-6800 Inline PCBA cleaning machine is mainly developed for the cleaning of PCBA in the electronics manufacturing industry. It uses the industry's most advanced cleaning process “water-based liquid” for cleaning, achieving 99% cleaning and environmental protection. The machine consists of a cleaning system, a rinsing system, a drying system, a filtration system.

5.3   Power control system

1. Equipped with ECO mode. There is a sensor in entrance,The water and power supply will  stop when there is no board                                           pass-by in set time.

2. Pump protection:Protections occur when running in lower chemical.

3. Over temperature protection:The heating unit will stop work when it gets to the setting  temperature.

4. Power-off protection:Equipped with UPS Standby-power- supply- system which will release  the PCBA when power supply                                  breakdown suddenly.

5. Equipped with emergency stop switch in entrance and exit to help cut down power supply  when emergency happened.
