As the demand for increased efficiency and cost-effectiveness in PCB fabrication process continues to grow, suppliers and OEM manufacturers seek ways to reduce production costs and enhance capacity, starting from the design phase. However, cost reduction often involves using cheaper materials or minimizing the use of conformal coating whenever possible.
You may often ask some questions
「Why not eliminate conformal coating?」
「Is conformal coating a necessary material in the PCB fabrication process?」
In PCB design, the material and manufacturing cost considerations are diverse. Typically, conformal coating accounts for approximately 1% to 2% of the total cost. The annual savings from not using conformal coating can amount to thousands of dollars. However, the decision to use conformal coating in PCB manufacturing goes beyond evaluating its cost; other factors must be considered.
The size of a standard PCB is around 5 inches by 5 inches, and the material cost for conformal coating is approximately $0.03 to $0.15 per unit. This cost depends on factors such as coating thickness and specific chemical properties, like silicone resin, acrylic resin, polyurethane, or UV-cured coatings.
“ PCB fabrication process– don't compromise quality for minor savings.”
Comparing the above cost in dollars to the overall cost of PCB production reveals a significant difference. While the percentage of conformal coating cost may only be in single digits, the price of PCBs used in applications like automotive and white goods can range from tens to hundreds of dollars. Therefore, the cost of conformal coating as a percentage of production cost is likely to be small. Seeking continuous cost reduction by eliminating or reducing conformal coating use might offer temporary benefits but can bring about hidden risks with numerous consequences.
