HP-7303 High-Capacity Triple-Valve Selective Conformal Coating
Machine
The HP-7303 Selective Coating Machine sets a new standard for
high-volume conformal coating productivity, featuring three
precision atomizing valves (H-905) that deliver unparalleled
throughput for mass production environments. With manually
adjustable valve spacing from 50-150mm, this triple-valve
configuration enables simultaneous coating of three separate areas
on large boards or parallel processing of multiple smaller
PCBs—effectively tripling output compared to single-valve systems
without expanding floor space.
Each valve maintains the proven H-905 performance: 1mm edge
accuracy, low-pressure atomization technology that eliminates
bubbles and wire drawing, and compatibility with all conformal
coating types (50-1500 CPS). The robust servo motor and ball screw
drive system delivers ±0.02mm repeatability even at maximum speeds
of 800mm/s, ensuring consistent quality across millions of boards.
With electrically adjustable conveyor (50-450mm), built-in UV
inspection lighting, and SMEMA interface for seamless line
integration, the HP-7303 is the definitive choice for automotive,
telecommunications, and consumer electronics manufacturers
operating at the highest production scales.
