Orange peel defect in conformal coating – uneven textured finish

Image showing orange peel defect in conformal coating. The PCB surface displays a rough, textured finish resembling the skin of an orange, caused by improper spray application, viscosity issues, or incorrect cure profile.

Why do so many conformal coating problems appear “random”?

In most cases, they aren’t random at all — they are symptoms of a process that was never aligned from the start. Conformal coating only works reliably when PCB design, environmental demands, coating chemistry, application method and inspection strategy all work together as a unified system. To help manufacturers establish stable, scalable and predictable coating […]

Inline Dip Coating – The New Era of Conformal Coating Automation

For many years, conformal coating was seen as a labour-intensive, operator-driven process. Whether spraying PCBs by hand or manually dipping assemblies, consistency depended heavily on individual technique. But the industry has shifted. Manufacturers now expect repeatability, digital traceability and real-time process control—and automation is becoming central to achieving these goals. At SCH, we are seeing rapid […]

Why Parylene Dimer Purity Defines Coating Performance

Clean chemistry, flawless coatings Behind every reliable Parylene coating lies the dimer — a crystalline, purified precursor that drives the entire deposition process. When sublimed and cleaved under vacuum, the dimer becomes a reactive monomer that polymerises onto every exposed surface, forming a perfectly conformal, pinhole-free film. But that level of precision depends on one […]

Masking Made Easy – 3 Ways to Reduce Defects in Conformal Coating

Masking is one of the simplest steps in conformal coating — and one of the most common causes of defects, rework and customer complaints when it goes wrong. Coating on connector pins. Adhesive residue left behind. Silicone boots leaking. Latex that tears or pulls the coating away. These issues cost time and money — but […]
