1
00:00:01,966 --> 00:00:04,166
Let's start paint soldering oil now
2
00:00:07,233 --> 00:00:10,166
Blow the mainboard a little with the rotary-air gun
3
00:00:10,733 --> 00:00:13,266
Let the mainboard have a certain temperature,
4
00:00:13,433 --> 00:00:17,666
so that it will be more uniform when removing the soldering oil
5
00:00:18,466 --> 00:00:20,466
No need to block the baseband
6
00:00:20,500 --> 00:00:24,333
Because the CPU we installed is medium melt solder
7
00:00:24,600 --> 00:00:28,400
Its melting point is lower than that of the baseband CPU
8
00:00:28,766 --> 00:00:31,400
So don't need to block it, it won't extrude
9
00:00:35,033 --> 00:00:37,300
Squeeze the soldering oil to the middle first,
10
00:00:37,733 --> 00:00:39,866
then use this needle to spread it
11
00:00:53,933 --> 00:00:55,100
We paint a thin layer
12
00:00:56,000 --> 00:00:58,300
Scrape it to the sides if there is too much
13
00:01:09,966 --> 00:01:13,033
This CPU is relatively easy to install
14
00:01:13,533 --> 00:01:17,533
These three areas are facing the three areas below, just cover it
15
00:01:25,233 --> 00:01:28,366
A 10's CPU has components on three sides
16
00:01:29,400 --> 00:01:32,866
After A10, there will be four sides with components
17
00:01:33,600 --> 00:01:36,400
So when you put it on, it's easier to deal with
18
00:01:40,000 --> 00:01:43,033
It's a little tight, push it out a little bit
19
00:01:44,966 --> 00:01:45,966
Almost done
20
00:01:46,566 --> 00:01:48,733
Then we start to heat with the rotary wind,
21
00:01:49,000 --> 00:01:52,100
the temperature is about 280-300 degrees
22
00:01:57,200 --> 00:01:59,700
It's better to get a flashlight in this direction
23
00:02:00,400 --> 00:02:02,633
to look at the solder pads in this area
24
00:02:36,766 --> 00:02:38,433
Remember to look at the CPU,
25
00:02:46,266 --> 00:02:48,266
there will be a homing action later
26
00:03:26,400 --> 00:03:28,766
Now the tin has slowly started to melt
27
00:03:46,800 --> 00:03:48,500
If you're stable with tweezers
28
00:03:48,500 --> 00:03:51,300
you can touch the corner gently with a tweezer
29
00:03:55,366 --> 00:03:57,600
Just touch it and it will bounce back
