now we start

tining the solder joints of the motherboard

use this inductor coil

which has been tinned from the last video

put it on the solder joint

2 pins are placed horizontally on both sides

add a little more flux to the corresponding

center joints of the motherboard

rotary air gun

the temperature is still around 300 to 320 degrees

low the 2 lamps of tin on the inductor coil

now the solder has been completely melted

then hold the inductor with twisters

drag back and forth on the motherboard

in this way the ting of the solder joints is ready on

now let's clean little

check the finish of the solder

to see if there are

any individual pins that are not added well

we can now clearly see

that all the sutter joints are now very full

and uniform in size

for veterans there is no difficulty in flightening

this effect with a starting iron

but it's very difficult to a beginner

in Doctor Coyle will make it much easier
