There are several factors that influence PCB pricing. Here are some common elements:
Layer count: The number of layers in a PCB, such as single-sided, double-sided, or multi-layer PCBs. Multi-layer PCBs, with higher layer counts (e.g., 4-layer, 6-layer, 8-layer), are more complex and typically more expensive.
Trace width/spacing: The width and spacing between traces on the PCB. Smaller trace width and spacing requirements demand higher manufacturing precision and may result in higher costs.
Material type: Different PCB materials, such as FR-4, high-frequency materials, etc., have varying costs and performance characteristics. High-performance materials generally have higher prices.
Surface finish: PCB surface finish options, such as HASL, ENIG, OSP, etc., provide protection and enhance solderability. Different surface finishes can have different costs.
Hole size/blind vias/buried vias: The types and quantity of holes on the PCB, including standard vias, blind vias, buried vias, etc., can also impact manufacturing costs. Smaller hole sizes and more complex via structures often require higher process requirements and costs.
Impedance control: For high-frequency or specific applications, precise control of circuit impedance may be necessary. Impedance control requires more stringent manufacturing processes and materials, potentially resulting in higher costs.
Order quantity: Generally, larger quantity orders have lower costs. Bulk orders allow for higher production efficiency and optimized material procurement.
Design complexity: The complexity of the PCB design affects the manufacturing difficulty and required process steps. More complex designs may require additional processes and inspections, leading to higher costs.
Production lead time: Urgent orders or expedited production requirements may involve overtime or accelerated production schedules, which can result in additional costs.
These factors are interconnected and vary based on specific circumstances. Therefore, it is advisable to have detailed discussions and obtain quotes from suppliers to determine the accurate pricing for PCBs.
