next we start to scrape the edge glue of the CPU

use this special knife

both street air or rotary air hot gun are okay

200 degrees no more than 200 degrees

adjust the air volume to the maximum

why 200 degrees

because some beginners are slow to operate

in the case of high temperature

if it takes a long time for us

to scrape the glue back and forth

the inductors and capacitors wrapped with this glue

around it are easy to be scratched and loosened

the temperature should not be too high

no more than 200 degrees will do

the blade scrapes back and forth

in this position of the glue

slowly scrape down from the surface

don't bean the hurry and script to the end directly

it is easy

to scratch the components around the murder board

and it is easy to skew with them

little by little

we have reached the bottom of this position

you can increase the magnification

slightly when operating

under the microscope

this will help us see clearly

prevent scratches on the motherboard during the process

it's been scratched to the bottom

in addition

there may be some small chips around the CPU

be careful not to scratch them when scraping

now the script a spot is a flashlight chip

after scratches

there may be leakage when the motherboard is powered

or there will be a large current after power on

upside has been scraped

let's scrape the right side

slowly script down from the place with most glue

all the glue on this side has been scraped off

let's scrape the lower side

actually

it's okay if you don't want to scrape this position

then the edge

this side must be scraped

because some CPUs are glued more

it awards a lot from the edge

later when we take off the chip from the motherboard

this position is the selected one

where we start to do it

if there is a lot of glue here

it will affect us to insert blade

the edge glue has been scraped clean
