Acrylic Conformal Coating Removal

Solvent removal while most conformal coatings can be dissolved in solvent you should make sure the solvent won t.

Acrylic conformal coating removal.

The gluedoctor can help advise which stripper is best suited for your removal get in touch here. The cir cw3500 circuitworks conformal coating remover pen is ideal for precise removal of silicone and acrylic conformal coatings from printed circuit boards during manufacture rework repair and prototyping. Chemical strippers are important for removing conformal coatings to allow their repair. Acrylic conformal coating is recognized for its high dielectric strength and fair moisture and abrasion resistance.

Pre drying or even better vacuum desiccation of the pcb will remove most of the moisture to assure best conformal coating protection avr80 conformal coating contains a uv trace which allows inspection of the pcb after coating to ensure a complete and even coverage. They are far less likely to damage pcbs components metals and plastics than other solvents. What generally distinguishes acrylic coating from other resins is ease of removal. Your best choice is the heavy duty flux remover suprclean.

The basic methods as cited by ipc are. Chemical removal via methylene chloride or hydrocarbon based solvents is recommended for silicone. A detailed process and guide for removal can be found in section 2 3 2 of the circuit technology center s ctc guide. Peeling some conformal coatings can be peeled from the circuit board.

The humiseal range of strippers are individually formulated for use on different substrates. This is mainly a characteristic of some silicone. Acrylic coatings are easily and quickly removed by a variety of solvents often without the need of agitation. It is a formidable cleaner with a high kb value.

Soldering through the conformal coating chemical removal in a local area mechanical abrasion. Application of avr80 conformal coating. The conformal stripping process is performed using a range of solvents and involves brushing or swabbing the area with solvent until the conformal coating is removed. Acrylic coatings like humiseal 1b31 can be difficult to remove.

Removal and stripping of conformal coatings conformal coating removal is used for stripping conformal coatings and solder residue from printed circuit boards. Chemical solvent method for conformal coating removal highly effective for removal of acrylic urethane and silicone printed circuit board coatings.
