What are some of the implications of the Hall Effect for PCB layout?
ByGrace June 24, 2025June 24, 2025
For me, one of the coolest things about kids is that they can be astounded by science and other phenomena that, as an adult, you are just accepting. I gave a five-year-old homemade magnetic slime for his birthday one year; consisting of iron oxide powder, Elmer’s glue, and liquid starch, the prospect of the black…

Concept and treatment of residual copper rate in PCB manufacturing
ByGrace June 24, 2025June 24, 2025
Concept of residual copper rate in PCB manufacturing: The manufacturing process of PCB starts with a PCB “substrate” made of glass epoxy or similar materials. The first step in manufacturing is to light-draw the PCB design wiring for the connection between parts. The method is to use negative transfer (Subtractive transfer) to “print” the circuit…

How to calculate the relationship between PCB line width and current
ByGrace June 24, 2025June 24, 2025
1.Calculation method First calculate the cross-sectional area of the track. The copper foil thickness of most PCBs is 35um (if you are not sure, you can ask the PCB manufacturer, 1 ounce is 35um, but in fact it is less than 35um). Multiply it by the line width to get the cross-sectional area. Pay attention…
