Restore the circuit diagram according to the PCB board
ByGrace July 21, 2025July 18, 2025
Schematic diagram production is the basis of PCB layout, so the schematic diagram restoration should be completed without errors. There should be no errors in the schematic design, and it must be cross-checked by another MCU development engineer to evaluate any errors in the design. Otherwise, the wrong schematic will be converted to the PCB…

How to reduce the design cost and curvature of PCB boards
ByGrace July 1, 2025July 1, 2025
If the wiring does not require an extra layer, why use it? Wouldn’t reducing the layer make the board thinner? Wouldn’t the cost be lower if the board had one less layer? However, in some cases, adding a layer can reduce costs. PCB boards have two different structures: core structure and foil structure. In the…
