Conformal Coating PCB
About Conformal Coating PCB
Conformal coating pcb spraying process is in the PCB assembly process to meet the needs of customers for environmental applications and configuration. As a professional PCB board coating provider, our factory is equipped with a professional production line, including two sets of conformal coating spraying equipment, UV inspection, baking and other automatic equipment. If your PCBA board has the requirements of temperature and humidity, durability, insulation, waterproof and dustproof, then you need the service of circuit board coating. Contact us to learn more about the benefits of Conformal coating pcb.
The Capabilities of Conformal Coating PCB
Provide fixture of PCBA board, effectively ensure the uniformity of spraying edge.
PCB coating support intensive, high – pin components of conformal coating spraying.
Work with fan-shaped spraying and point-needle spraying to cover the surface requirements of various components.
By pcb coating spray, some components, such as connectors, antennas, WiFi modules, etc., can be selectively avoided according to the actual needs of the customer.
Some pcb coating machines support double-sided spraying and baking
Fully pcb coating machine, the average spraying time of each PCBA is within 0.5~3 minutes
Why Do PCB Boards Need to Use Conformal Coating?
Conformal coating pcb can provide a high degree of insulation protection for the printed circuit board
Conformal coating pcb can prevent damage caused by thermal stress and mechanical stress
Conformal coating pcb can provide a barrier to prevent particle contaminants from reaching the surface of the PCB.
Conformal coating pcb can reduce or eliminate electronic operation performance degradation
The Different Types of PCB Conformal Coatings
(B) From the curing mode, there are solvent-based curing, room temperature curing, thermal curing and UV curing.
The Different Processes Of Circuit Board Coating Spray
Automatic Spraying — The most commonly used economic and efficient
pcb coating spray method, low installation/labor cost, high production efficiency, uniform spraying to ensure spraying quality of PCB.
Dipping — PCB is completely immersed in the circuit board coating spray solution to complete the spraying process at a higher speed, and will not lead to material waste caused by excessive spraying. For dipping, generally uses acrylics and urethanes solvent-based conformal coatings.
Selective spraying — Selective circuit board coating spray can accurate coverage in a specific area and no waste of material, suitable for batch coating. Connectors and other devices that are not sprayed shall be shaded.
The Applications of Conformal Coating PCB
Conformal coating spray for pcb provides protection for electronic circuits in household appliances against water, chemical detergents, adverse external environments, and household pests.
(2) Automotive Electronics
The conformal coating can be used to protect the automobile PCB boards from gasoline, salt spray, brake fluid, and other hazards. Therefore, in the automotive industry, the conformal coating has become an indispensable condition to protect the stability and lasting work of electronic devices.
(3) Aerospace Electronics
Due to the long-term and high-pressure working environment in aviation equipment, the stability of electronic equipment is very strict. PCB and components surface coated with conformal coating has good pressure resistance and high stability advantages, so it is widely used in aviation and aerospace products.
(4) Marine Electronics
Seawater is corrosive to a certain extent, which will cause harm to the electrical circuit of ship equipment. The use of conformal coating maximizes the protection of surface and underwater equipment.
(5) Medical Electronics
Conformal coating PCB can protect electronic equipment from external chemical agents and special environment erosion, to ensure its continued stability.

High volume PCB Assembly refers to bulk printed circuit board assembly projects of 10,000 pieces or more, in one cycle of production with DFM and DFT. This is highly popular in high-end modern electronic manufacturing companies.
The benefits of high volume PCB Assembly are
- One-time design and prototyping services
- Faster time-to-market
- cost-efficient as you can purchase in bulk
- Consistent quality
- Production uniformity
- Shortened production cycles
Choosing a high volume PCB manufacturing company is quite a daunting task in this cut-throat competitive space. Two of the most common things one looks for in any company are quality and cost-effectiveness. Besides, you can also look into their experience, manufacturing capabilities, turnaround time, responsiveness, value for time & money, flexibility, and customization options.
Mer-Mar Electronics is a USA-based PCB fabrication and manufacturing company with over 4 decades of experience in PCB assembly services. We are an ISO-certified and ITAR-compliant company. We offer high volume circuit boards in the least turn-around time, flexible shipment plans, and at competitive prices. We follow a client-centric approach to ensure guaranteed quality satisfaction.
You can send your Gerber files and BOM to us We would provide you the quote Give your confirmation and the order We start with PCB fabrication component procurement We perform soldering and testing Finally, we go for packaging and shipping to you.
Well, we can accurately present the time based on the complexity of your board. Let us first go through your Bill of Materials (BOM) and Gerber files. See how much time it takes.
Yes, we do. After the PCB assembly, we can launch an x-ray test on your components. The additional charges will be levied after the assembly test.
We make sure you face zero issues. However, if unfortunately, you face any problems with the boards, please send high-resolution images for proper evaluation. If we get a confirmation of the root cause, we will take responsibility for your board repairs.
As part of the high volume production process, we provide components and parts procurement for optimizing the manufacturing process at zero price. Also, repeat customers may also take advantage of loyalty discounts to reduce the long-term costs of production. Depending on your requirements, we would let you know the final costs.
Yes. We do offer reliable customer support for your orders from start to finish. We will walk you through every step of the process and our PCB experts will also be available all the time.
