PCB Board Price
Reveal the mystery of PCB circuit board pricing: manufacturers calculate the method of analysis
In the precision world of electronic equipment, PCB printed circuit boards play a role in connecting and supporting the electronic components of the ‘neural network’ role. As the cornerstone of modern electronic technology, PCB quality and cost directly affect the performance of the final product and market competitiveness. Therefore, understand how PCB circuit board manufacturers calculate the price, for electronic engineers, purchasing managers and even the vast number of electronic enthusiasts is crucial. In this paper, we will introduce in-depth PCB price calculation of several common methods and the considerations behind them, to help you better grasp the cost, optimise the procurement strategy.
1. Material Cost Estimation
Basic materials: PCB price calculation begins with the basic materials, including copper plate, copper, solder resist ink, silkscreen ink and so on. Different materials (such as FR-4, aluminium-based, Rogers, etc.) and thickness of the copper-clad board price difference is significant, and high-performance materials often cost more. Manufacturers will select the appropriate material according to the customer's requirements for PCB performance and calculate the base cost accordingly.
2. Size and Layers
Size and area: The size of the PCB directly affects the amount of raw materials used, usually, the larger the area, the higher the cost. Manufacturers will be based on the length and width of the PCB dimensions to calculate the material consumption, and combined with the unit cost of materials to calculate the cost.
Number of Layers: Multi-layer boards require more fabrication processes and materials than single or double-layer boards, and the cost rises with each additional layer. The number of layers directly determines the manufacturing complexity and time cost required.
3. Process difficulty and special requirements
Drilling and hole: PCB holes (including through-hole, blind holes, buried holes) number and type will affect the processing costs, especially micro-hole or high-density over-hole, requires more sophisticated processing equipment and technology, the cost is naturally higher.
Surface treatment: different surface treatment (such as gold plating, tin plating, OSP, etc.) costs vary, of which gold plating due to its excellent corrosion resistance and solderability, the cost is relatively high.
Special requirements: such as high TG materials, halogen-free, high-frequency boards and other special requirements, as well as strict standards for electrical performance, will lead to cost increases.
4. Production batch and delivery time
Production volume: Lot size has a significant impact on price. Mass production can dilute the fixed costs such as moulding fees, machine commissioning costs, etc., thus reducing the cost of a single piece.
