Argus Systems is one of the leading electronic manufacturing company with specialization in quick turnaround of Prototypes and low to medium scale production. Our PCB Assembly manufacturing facilities are ISO 9001 & ISO 13485 Certified. PCB Conformal Coating and Potting is a protective chemical coating that conforms to the circuit board topology. The conformal coating helps in protecting electronic circuits from harsh environments that may contain moisture and chemical contaminants. Being electrically insulating, it maintains long-term surface insulation resistance levels and ensures the operational integrity of the assembly.
Some are the application use conformal coating include high-reliability defense, automotive and aerospace, where the coating is used to protect against various combinations of moisture, salt sprays, aggressive chemicals and vapors, large temperature variations, mechanical vibrations. The conformal coating also means that not only protects, but also serves to enhance product reliability and thereby reduce the potential cost and damaging effects of early field failures.
PCB Conformal Coating
- Dipping- This is limited to materials that do not cure quickly by moisture, oxidation, or light.
- Selective Robotic Coating- If the Correct dispense head is selected all coating types like Asymtek, PVA, or DIMA will be applied.
- Spraying- All conformal coating can be applied by using hand spray or
- Brushing- In brush coating requires extremely proficient and skilled operators in order to be suitable for production.
Advantages of conformal coatings:
- Protect the assembly against chemical and corrosive
- Minimize environmental stress on a PCB Assembly.
- Insulating properties allow a reduction in PCB conductor spacing.
- Helps in eliminating the need for complex, sophisticated enclosures.
- Lightweight
- Protection against thermal and mechanical shock
- Protest against environmental hazards including moisture chemicals and other corrosive elements
- Easy removal, repair, and replacement
- High flexibility
Electronic Potting
- Electronic potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for resistance to shock and vibration and for the exclusion of moisture and corrosive agents.
- In the Electronic potting process, an electronic assembly is placed inside a mold which is then filled with an insulating liquid compound that hardens permanently protecting the assembly the mold is part of the finished article and can provide shielding or heat-dissipating functions in addition to acting as a mold.
- Electronic Potting compound support: Hard Tamper Proof Potting Compound, Silicone Potting Encapsulant, flexible clear transparent epoxy potting compound.
