Electronics Potting&Coating services

The most common ways to extend the life of circuit boards in electronic products are potting or coating to protect electronic products from corrosion and damage to the electronic components and electrical connections of the circuit board by isolating the external environment.


ZMS usually provides customers with the following methods

Tri-conformal coating
This is a chemical substance composed of resin, solvent, additive and curing agent in a suitable ratio. It has excellent adhesion, chemical resistance and physical stability. It is generally transparent and can be added with fluorescent agent. It can play a very good role in circuit board protection and very competitive in cost.
At Zero Mistake Solution, after determining the areas that do not need to be covered with the customer, ZMS will customize a unique fixture for each customer's project to cover the designated area, and then use dedicated tri-conformal coating equipment and environmentally friendly tri-conformal coatings to spray the products in batches. During the spraying process, we will require staff to wear high-level protective clothing and masks to ensure the health and safety of employees.
Parylene coating
Parylene coating is a material that combines sealing, permeability, insulation, lubricity, moisture and mildew resistance, and thinness more comprehensively than conformal coating. The application scenarios and fields will be more extensive, and it also plays a very critical role in the protection of advanced and precise circuit boards.
Zero Mistake Solution can provide customers with excellent and cost-effective Parylene coating services, especially for electronic products with higher precision and waterproof requirements. Parylene is a perfect protection solution, which can make the wrapped circuit board waterproof to IP68, so that the circuit board can be placed in water for a long time without any functional impact.
For Parylene coating work, we have a special spraying production line in Shenzhen, which can select the most suitable spraying solution for customers according to their product performance requirements.
Epoxy resin potting
Epoxy resin is a very hard substance after curing. It is usually used in electronic products under harsh outdoor conditions. The inside of the electronic products covered by the cured epoxy resin will become very hard and can effectively resist external physical impact. Unless special chemicals are used to dissolve it for more than a few hours, the protection life of epoxy resin can last at least 5-10 years. It is a very good choice for circuit boards with such protection requirements.
Silicone Potting


  • What is electrical potting compound?
    In electronics manufacturing and assembly, potting materials are compounds that can fill and seal cavities in electronic assemblies. By doing so, potting compounds protect components from vibration and shock.


  • What is potting in manufacturing?
    In electronics, potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for resistance to shock and vibration and excluding moisture and corrosive agents.


  • What is the best material for potting electronics?
    Silicone potting compounds feature a unique combination of flexibility, high and low temperature resistance while maintaining constant mechanical properties over a wide range of temperature. Silicones are soft and flexible with high elongation, making them suitable for potting sensitive electronics. 


  • Is it possible to take the potting material off if needed maintenance for the circuit board?
