ipod testing

[350x]

hello new here. can some tell me the basic tools i will need to test a ipod logic board.also where i can buy them.any help would be greatly appreciated.

What would be the purpose of such testing? Is this for a single unit or do you intend to test a whole batch of units?

want to start out testing a few units

What kind of a budget are you considering and what kind of test report are you interested in seeing?

iPods as well as most modern electronic devices were never designed for repair. Aside from simple headphone jack re-soldering or battery replacement most of the circuitry will be looking for the part where the smoke came out.

Another problem is ordering a replacement module (LCD, main PCB, harness) will probably cost more than the unit is worth, and unless you're an authorized Apple service depot getting service manuals will be difficult.

What do you use to repair electronics now? Can you desolder TQFP, BGA?

I'm guessing that there are no general purpose readily available test tools. A decent oscilliscope will run $3000-5000 for testing video outputs, and for general purpose signal tracing.

Equipment for reflow soldering and desoldering of surface mount components will easily outstrip your budget.

Do you know about ROHS 2006 and why you should not be using solder with lead in it to repair a board that was manufactured with lead free solder?

I would never buy something manufactured by an automated machine that had been hacked by hand.

Maybe the folks who manufature the boards have a custom test fixture that might cost between $500,000 and $3,000,000.

In the absence of reliable information on what the proprietary chips do, how in the world do you expect to troubleshoot and repair anything this complicated. Are you sure you can even get it apart without damaging it?
