Industry Background
In PCB wet processing, residual moisture after cleaning can negatively impact developing, etching, plating, and inspection stages. As PCBs become thinner and denser, non-contact, uniform drying systems are essential for quality assurance.
Common PCB Drying Problems
Problem 1: Water retention in holes and edges
Complex board structures trap moisture, increasing oxidation and short-circuit risks.
Problem 2: Uneven drying
Traditional nozzles create concentrated airflow, causing inconsistent drying.
Problem 3: High energy consumption
Hot air or compressed air solutions consume excessive energy and slow production cycles.
Engineering Causes
-
Non-uniform airflow distribution
-
Improper drying angles and distances
-
Mismatched air volume and pressure
