  • The difference between positive and negative PCB circuit board

    PCB circuit board negative film: generally we talk about the tenting process, the chemical solution used is acid etching negative film because after the film is made, the required circuit or copper surface is transparent, and the unneeded part is black. After the circuit process is exposed, the t...

  • Experience sharing of decoupling capacitor placement in PCB design layout

    Experience sharing of decoupling capacitor placement during PCB design and layout. For capacitor installation, the first thing to mention is the installation distance. The capacitor with the smallest capacitance has the highest resonance frequency and the smallest decoupling radius, so it is plac...

  • PCB power cord routing rules

    1. Decoupling should be carried out between the power supply pin and the ground pin of the chip. The decoupling capacitor adopts 0.01uF chip capacitors, which should be installed close to the chip to minimize the loop area of ​​the decoupling capacitor. 2. Widen the width of the power line and gr...
