Truly an informative video. When removing the component and then reballing it, at what temperature ranges and for how long do you work? I tried, and the circuit board bulged. The operating temperature and temperature ranges of the device must be very important. thank you very much again
My temps work for my machine, they won't work for yours. Practive one bad boards get a feel for what works and what doesn't. Practice makes better. There is no short cut answer I can give you.
Hello, I need help identifying a part that has exploded. It's on the power side where the chopper transformer is. Thank you. A picture of this part helps me a lot
Curious about top and bottom temperatures. Other than plugging into the truck are there other ways to introduce electricity to look for other circuit faults?
Top and bottom temps depend on your mahcine. If you use the same temps I do, it won't work for you. Yes there are bench testing tools we use. Some are better than others.

Yeah reballing is a different skill for sure. I don't actually do it, one of my techs does it for me. I trained to do it with him, he showed me how and I know how to do it but am not very good at it either.
Trial and error otherwise known as experience It's really hard to identify a fauty solder joint below a processor because you can't just put a mutltimeter to it or use a tool to determine it's the issue. So you have to go based on symptoms, the fault that is occuring and try a few repairs until one sticks and then use that experience of having fixed a few to know what symptoms are commonly caused by what failing components in the circuit. Yes I know it's not the sexy clear cut answer you were looking for but that's how it goes a lot of the time.
Yes, this is also true. We see that a lot with the CPC4 actually. Truckers will say that during certain weather like in the very early morning or night time, it won't work but after the sun rises for a few hours and it warms up then the truck works.
The video and the comments taught me a lot about diagnosing an issue. Thank you for another excellent video!
Glad it helped!
So you guys know what usually fails on the Detroit ECM the DDEC V?

Wow I'm impressed
Thanks!

Sorry I don't think I can help you there.

I have a Hyundai loader with Cummins engine that uses CM870 ecm. How to connect Inline 6 to diagnose the engine.
Unsure sorry
Great
Whats the model number of your bga machene?
And whats the name of the little tool you used for pudh the ic?

I happily do most of what you do but reballing something like that is mildly terrifying and I'm not sure when I will attempt that lol.

how did u know that chip was the problem?

One common way is if the device's functionality seems to be be tied to whether it is hot or cold. That could indicate a bad solder joint.
Yes, this is also true. We see that a lot with the CPC4 actually. Truckers will say that during certain weather like in the very early morning or night time, it won't work but after the sun rises for a few hours and it warms up then the truck works.
Great Video! HMU if you want a "fried" CM2350 for a video!
