Automated pressure control system and method for a cleaner

A cleaning apparatus for cleaning electronic substrates including printed circuit boards and semiconductor product assemblies, the cleaning apparatus comprising:

• at least one cleaning module configured to treat electronic substrates;
• and
• a conveyor system configured to transport the electronic substrates through the at least one cleaning module,
• the at least one cleaning module including a fluid management system having
• a manifold coupled to a source of fluid, the manifold including at least two outlets, a first outlet and a second outlet,
• a first automatic valve coupled to the first outlet and to a first conduit leading to one or more first spray nozzles and a second automatic valve coupled to the second outlet and to a second conduit leading to one or more second spray nozzles, and
• a first pressure sensor coupled to the first automatic valve and a second sensor coupled to the second automatic valve, the first pressure sensor being configured to measure pressure of fluid flowing through the first conduit and the second pressure sensor being configured to measure pressure of fluid flowing through the second conduit,
• wherein at least one of the first automatic valve and the second automatic valve is configured to adjust the flow of fluid through its respective conduit based on the pressure measured by one of the first pressure sensor and the second pressure sensor.

A fluid management system of a cleaning module of a cleaning apparatus to clean electronic substrates including printed circuit boards and semiconductor product assemblies, the fluid management system comprising:
