Analysis of the Dual-Valve Design in Second Intelligent’s Inline Precision Coating Solution

 Analysis of the Dual-Valve Design in Second Intelligent’s Inline Precision Coating Solution

Background of the Solution
Based on Second Intelligent’s current inline precision coating solution and the customer’s process requirements (conformal coating machine+ localized precision dispensing), the core logic behind the design of the “Z-axis Dual Valve Assembly” is not simply to add another valve, but to solve the problem of “different process requirements existing on the same product” in electronic coating applications.
According to the solution proposal, the customer is currently using:
1.Conformal coating material
2.Viscosity: 15~20 cps (low viscosity)
3.Process requirements include
1.Large-area spray coating coverage
2.Localized precision dispensing / touch-up coating


Second Intelligent’s dual-valve inline precision coating solution is not simply about adding another dispensing valve. Instead, it adopts a combined “spraying + precision touch-up dispensing” process design to solve the challenge of balancing large-area coating efficiency and localized high-precision coating in electronic conformal coating applications.

The atomizing valve achieves high-speed and uniform coating coverage, while the needle valve enables precision touch-up coating in complex areas. Combined with the CCD vision auto-correction system, the solution effectively reduces missing coating, overspray, shadow effects, and manual rework risks, significantly improving product yield, process stability, and production automation efficiency.
