Hi Mike,

It depends on what components and section you want to check on those boards. For power section you need esr and ring tester. For smd board, you need huntron tracker, smart tweezers, digital scope, and etc.

Hi Rohmell,

Yes i have it and only use for comparison work. As for checking the winding I use Blue Ring Tester.

The Huntron Tracker seems to be a good unit to use as an 'Entire Circuit Board Tester", as long as you have an identical working sample board.
We have been using the Huntron tracker to detect shorts in pulse transformers. The transformer has 4 identical windings. When the Tracker is connected to any winding that is good, the display looks like the eye of a sewing needle. If the display shows a vertical line, then one of the windings is shorted, even one that is not connected directly to the Tracker! (the shorted winding is loading down the entire transformer)
While connected to one winding, by shorting the other windings with a pushbutton switch, it will show a vertical line on the display. This indicates that the other windings are good, .because you are now manually shorting the other windings via the pushbutton switch. if the button is pressed, and there is no change in the display, then that winding is open.
Thai method is much faster than using the HP LCR meter that we were tesing with before to chech each individual winding.
Mr. Yong, you have a Tracker, how do you like it? I think if you practice with it, you will find it to be a very useful tool.
Yes, it is an expensive piece of test equipment to buy, but you can build your own simplified version:

Hi mike,

Theybare good in locating shorted component in the high density board. They can't be used to check for shorted winding in transformer, bad ESR in electrolytic capacitor and etc.

I agree Mr jestine.We only need to look for all the testing equipments as you are helping us to do so.

i strongly agree.It's nice to have all that test instrument to do the repair quite easily in a short period of time compare to one multimeter..

HI Waleed,

That was a real gem for those who repair Digital Cameras.

totally agree. though i have seen a computerized meter that can test digital cameras. plug the camera into it and it will tell you where the fault is and if does not, it will give you a choice where to look.
