    Microcontroller shielding

    Thanks. I have taken some precautions on the board like separating RF section from rest of the circuitry and providing filtering caps to controller and to where its necessary else where and providing proper Grounding but still I want to protect the controller from external radiations.

    Capacitive Power Supply

    Hi I want to design a capacitive power supply , with i/p voltage as 90V to 270V and o/p voltage as 24V , how can I calculate maximum current of the circuit? I calculated the capacitance of the X-rated capacitor by the formula X = 1/(2* pi*f*C) where f=50-60Hz. Then calculated the current by...

    PCB layout software query

    I did one trick , in the same project I added separate pcb files as the no. of PCBs to make and then in each pcb file imported the schematic data and deleted the components along with rooms which are not related to that particular PCB. This worked for me as I made the PCBs and the project is...
