Hi, All:
I have problem with a big voltage drop on my PCB. When I connect my PCB with 1.8V from power supply, I saw a significant voltage drop and the current rises up 0.05A. Can anyone tell me what this problem is ? My assumption is a short loop in the PCB. I do not know I am right or wrong. Please give me some advice. Thanks for advanced.

If there's a short loop, the voltage will drop to near 0. I think the problem may be caused by some fault parts, or the power supply circuit itself.

Re: Help on PCB

Any organic flux still on the board near sensitive analog circuitry? That stuff can mess up a good design quick if you don't get it all off!
