Techspray FAQ: How To Double-Check Conformal Coating Coverage?

Описание: Conformal coating with UV tracer can be inspected with any typical UV lamp, also called a “black light”, which has a wavelength of 320-380 nanometers. When you have full coverage, it glows bright. Shadowed areas, pinholes, and other gaps will show up as dark areas.

PROTECT ELECTRONICS FROM EXTREME ENVIRONMENTS

Techspray offers SR, AR and UR conformal coating formulas for a wide variety engineering requirements including thermal, moisture & static resistance. All coatings are IPC-CC-830B and UL94 V-0 qualified.

Techspray offers a variety of conformal coating formulas for differing field or engineering requirements and is IPC CC 830B and UL94-0 Qualified or rated. Specifications generally depend on the type of protection needed: e.g., thermal, moisture, or static resistance.

Coatings contain Opti/Scan (except LED Coating) to allow quality control inspection of coverage and evenness of the coating on a PCB. A coated board can be passed under a standard, low-cost UV (short-wave black) light to fluoresce the coated areas. The brighter the glow, the thicker the coating.

Application methods:
Dip – High volume method to fully coat boards. Thickness of the final coating is controlled by viscosity and withdrawal speed from the pot.

Conformal Coating Spray – Computer controlled selective spray systems eliminate the need for masking. Higher viscosity is generally needed (70-200 cps) to create precise edge definition and prevent splattering.

Manual Application – Aerosol and brushing are generally used for small production runs, rework and repair. The aerosol needs to be compatible with the original coating if it’s rework.
