PCB Copper Weight: Understanding oz, Thickness, and Current Capacity
PCB copper weight defines the thickness of copper conductors on printed circuit boards, directly determining current carrying capacity, resistance, thermal performance, and signal integrity. Copper weight ranges from lightweight 0.5 oz/ft² (0.7 mil) for fine-pitch applications to heavyweight 6 oz/ft² (8.5 mil) for power electronics. Understanding copper weight selection enables designers to optimize board cost, […]
OSP vs HASL: Which PCB Surface Finish is Right for Your Budget
OSP vs HASL are two of the most cost-effective PCB surface finishes available. OSP provides excellent solderability with a thin organic coating, while HASL offers superior shelf life and durability through a tin-lead or lead-free solder layer. The choice between them depends on your assembly process, storage conditions, and application requirements. Key Takeaways OSP offers […]
