Introduction: In the previous article, we introduced the manufacturing process of PCBs, but we would like to delve deeper into the aspects of via copper thickness and the aspect ratio of PCB vias. Definition of PCB Copper Thickness The thickness of copper in a circuit is measured in ounces (oz). So, why is thickness expressed … Read more
1. PCB Current and Trace Width The calculation of PCB current-carrying capacity has long lacked authoritative technical methods and formulas. Experienced CAD engineers can make relatively accurate judgments based on personal experience. However, for new CAD users, this can be quite a challenge. The current-carrying capacity of a PCB depends on the following factors: trace … Read more
In the production of PCBcircuit boards, the thickness of the gold plating and the thickness of the copper foil represent different process parameters. Below are the definitions and commonly used units for these parameters: 1. Copper Thickness (Copper Thickness) The copper thickness refers to the thickness of the copper layer on the surface of the … Read more
