2. Currently, PCB circuit board production quotations are typically provided by factory engineers.
3. With the ongoing advancements in Internet technology, numerous board factories now offer online pricing platforms for PCB circuit boards.
4. However, due to the nascent stage of e-commerce within the manufacturing industry, online quotations are limited to relatively simple board designs.
Why is the quotation for PCBs so complicated?
PCB circuit board quotations are mainly determined by several key aspects:
1. PCB area (size)
Area refers to the size of the PCB design drawing. If it’s a rectangle, it’s length by width. For circles or other irregular shapes, the maximum contour range is calculated. Generally, material waste due to irregular shapes should be minimized. Larger volumes per board result in lower prices.
2. Base material
The base material is crucial for PCB manufacturing, and factories typically have long-term partnerships with suppliers. However, for PCBs with special requirements, designers must specify the material, which can affect the price. For instance, Rogers material for microwave RF costs significantly more than standard materials like FR4.
3. Board layers
Commonly used materials include FR4, High TG, and others. The number of layers affects the price, with more layers increasing costs exponentially.
4. Production cycle
Production time for single-sided and double-sided boards is typically 3-4 days. Expedited options like 48-hour or 24-hour service are available at higher costs, starting after all design issues are resolved.
5. Special processes
Beyond standard production capabilities, additional costs may arise if the design requires special processes or materials outside normal factory operations.
6. Additional considerations
Factors such as board thickness, solder mask color, surface finish, electronic testing, number of boards, and character color can also influence pricing and production timelines.
Many PCB manufacturers now offer automated ordering systems online, simplifying the process of submitting design files for production.
