Problem with a big voltage drop on a PCB

[jakin]

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.

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!
