The price of PCBs is complex, influenced by factors like material diversity, surface treatment, board complexity, copper foil thickness, quality standards, tooling and testing fees, payment terms, and order quantity and delivery time, all contributing to varying costs.
PCB factories use various surface treatment methods for PCB prototyping, each with unique characteristics. Chemical silver is recommended for lead-free soldering and SMT, while HASL offers complete wetting of the copper surface and is suitable for lead-free soldering and visual inspection. Nickel gold is suitable for lead-free soldering, SMT, and resistance to environmental attacks. Electroplated nickel-gold is widely used for contact switch design, gold wire binding, and electrical testing. Nickel-Palladium-Gold is suitable for bonding gold and aluminum wires, lead-free soldering, and is cheaper compared to ENIG.
