Reg-short circuit board

[dinesh2931]

We have short circuit problem in PCB board.By early we found that is was due to the 12 v short and removed all the components related to the 12 v capacitors,transistors (MOSFET),almost all 12 v component but the short is still exist
Can I get a solution what to be done further to solve this???

Hi,

a textual desctiption isn´t useful. Post a picture of your PCB .. with some informations in it.

We don´t know if you are talking about single layer or multilayer...power plane or traces...

To locate a short circuit on a PCB I usually use a current limited adjustable power supply (100mA...1A, about 1V) and a mV meter.
Then measure the voltages along the signal path. The smaller the voltage the closer you are at the short circuit.

Hi,

Thank you Klaus for the response.

See we are not supposed to send our PCB picture to anyone hope you understand.
