1. Clean PCB
To ensure proper adhesion and reduce the potential for defects such as bubbles, clean the PCBA surface. If cleaning with an aerosol flux remover, hold the PCBA at a 45° angle or greater to allow the solvent to flow down, off the board, taking the contamination with it. Start at the top of the PCBA and work your way to the bottom using a back and forth sweeping motion.
To remove flux from tight areas, use the extension tube (straw) that is included with most flux removers. For tenacious, baked-on residues, some flux removers include a brush attachment. Click here for a full video demonstration on using an aerosol flux remover. Click here for a video on cleaning with a brush attachment.
2. Apply masking over areas not to be covered
Because conformal coating is insulative, contact areas should be masked before the coating process. Engineering specifications might require keep-out areas for other reasons (e.g. compatibility, secondary processes to follow).
Polyimide tape or polymide film (e.g. brand name Kapton) is commonly used to mask broad areas (e.g. gold fingers). NOTE: adhesives from tape has potential to interact with a coatings solvent carrier, or cause the coating to dewet or back away from the masked area.
For masking over standard components or geometries, masking boots can be used that slip over the keep-out area, and pulled off and reused (and periodically cleaned) when complete.
Temporary solder mask is ideal for uneven surfaces or areas that vary from job-to-job. Peelable mask is recommended because the layer of coating makes it difficult to wash off water-soluble masks. To hand apply, hold the bottle at an angle (roughly 60°), which will ensure a thick enough bead for ensure easy removal. Clear here for a thorough guide to temporary solder mask.
3. Apply multiple thin layers
Similar to paint, conformal coating works best over multiple thin layers instead of one thick coat. Spraying too close can result in bubbles, dripping, or an uneven coating. Hold the aerosol can 8-10” from the surface of the board. Perform consistent, slightly overlapping sprays from board beginning to end. The speed of the passes controls the amount of coating applied.
Also, apply layers from all sides of the board at approximately 45-degree angles to minimize the “shadow effect” from taller components being sure to avoid any voids in the spray. Perform the same process on board underside. Repeat all steps depending how thick of conformal coating is needed.
4. Identify voids under UV light
Inspect the quality of the coating under a UV “black” light. Since conformal coating is clear and colorless, it is difficult to reliably see defects under normal light. UV tracer is added to most coatings, so it glows under a typical UV lamp with a wavelength between 320 and 380 nm.
5. Brush coating to repair voids
Coating can be applied by a small technical brush to rework shadowed areas, pinholes, and dewetted areas. Dewetting is a symptom of contamination, so if it continues to dewet, you might have to strip the coating from the PCBA, clean, and start over. Click here for more information on common coating defects and their causes.
Use a brush with fibers rated for conformal coating, otherwise the fibers have the potential to interact with the harsh solvents common in conformal coatings. Spend the money on a high quality brush to avoid lost bristles turning into FOD (foreign object debris), a common coating defect.
Please verify datasheet specifications to ensure products will work for the exact application.
