2. Solder mask and silk screen printing
Solder mask and screen printing are additional process steps in
PCB manufacturing. The
brand and variety of ink used for the solder mask will determine the price. If these
processes are added, the PCB price will rise.
3. Different process requirements
Different surface treatment processes in PCB production have different prices: Immersion
gold has the highest cost, and lead-free HASL, HASL and OSP are cheaper. Other
conventional processes also have different charges, such as tin, silver, and gold.
Different wiring and impedance control will also affect the final PCB production cost.
For details, please check our “SURFACE FINISH” details.
4. Different technical difficulties
Even if it is the same material, the same process, the technical difficulty of
PCB
manufacturing will cause different prices. The aperture is different, the line width is
different, and the price is also different, which is related to the scrap rate.
