The cost of a Printed Circuit Board (PCB) is influenced by several factors. The complexity of the design, including the number of layers and the density of components, significantly impacts the price. Material choice, such as FR4, polyimide, or metal core, also plays a crucial role, with more specialized materials costing more. The size and shape of the PCB, as well as the quantity ordered, affect the overall cost. Advanced features like high-frequency capabilities, controlled impedance, or heavy copper add to the cost.
Additionally, the manufacturing process, including the precision required and the type of surface finish (like HASL, ENIG, or OSP), can influence pricing.
Finally, lead time requirements and quality control measures also affect the final cost, with faster delivery and stringent testing procedures incurring higher expenses. At EXPERT-EMS, we are proud of our unbeatable prices so don’t hesitate to contact us for a price quote.
