Hi Everyone
I've just rebuilt about 12 of my Mac Portable's however I had one issue, when I replaced my some of my portables SMD caps with Tantalums, well 3 of them caught fire! :disapprove:
This happened on the Non backlit and Backlit model.
I used the correct rating on the tantalums, I dont quite get why this occured, I do not completely understand how the technology differes between the SMD caps and tantalums, I always assumed the ratings are the same it was all good.. But apparently not.
Not sure if it has to do with the fact I am using a 7.5v 3.0a power adaptor for my test runs, but either way, can anyone suggest why such a thing would occur? After scorching two boards pretty severely now I am concerned with the tantalum re-build of the Mac Portable...
Could it also have to do with other ageing componentry?
Any thought would be welcomed...
