Yeah. Especially custom Apple things like the SMC, which is a small MCU with its own custom firmware. Apple doesn't sell those to anyone, except preinstalled in a Mac. If you know where to buy those, ITelektronika, then you know a secret the repair pros don't know.
Oh.......
Of course, you can dig a chip that is not available. In fact you can find plenty of them.
But it does not confirm his statement, that the new chips are unavailable and that all the chips used.
Repeat once more.
You can not buy every chip. But most of them are available. He is in the video showed a bunch boards on which they are remove BGA chips, mainly GPU. Explaining that those chips you buy on E-bay. This is not true. I gave an example.
I have not written anywhere that you find every chip, you miss my point.
In the video, which was recorded later, he does reflow. With the heat gun, without preheating.
For those who are familiar with repair of motherboards, should not be special explanation how much it is wrong.
We all make mistakes. Someone learns from those mistakes, someone does not.
can you sell me some? I would be interested in G86-731-A2 and G86-771-A2. New original from reputable source, preferably manufacturer
No I can not sell you any BGA.
I order from this reseller
http://www.see-ic.com/goods-118.htmlAs you can see, this chip has date code 1408, it is chip that is manufactured 2014 with new underfill.
My advice is to order 10 pieces or more, if are new must be with the same date of manufacture packaged in a row. With this reseller in 95% of cases never had a problem. The others did not, regularly sent me used chips. But you can see that, after all that I have said, give a guarantee of one year. If you have a reclamation more than a few percent, something is wrong. Or chips or your work.
