    Today I will introduce a consumable that is often used in the maintenance of electronic products

    2

    00:00:09,900 --> 00:00:11,000

    Dust-free cloth

    3

    00:00:11,400 --> 00:00:15,566

    It is mainly used to clean the surface of some electronic products

    4

    00:00:15,966 --> 00:00:18,200

    For example,mobile phone

    5

    00:00:18,933 --> 00:00:25,066

    If you sell second-hand mobile phones, you may often use a dust-free cloth to wipe some mobile phone cases

    6

    00:00:25,333 --> 00:00:28,500

    Or cleaning the surface of the laptop

    7

    00:00:29,000 --> 00:00:32,733

    The main function is to clean the circuit board during maintenance

    8

    00:00:34,466 --> 00:00:39,700

    In addition, it is used to clean the oil on the surface of the screen during lamination

    9

    00:00:40,266 --> 00:00:44,566

    Let's take a look at the use of dust-free cloth when repairing the motherboard

    10

    00:00:45,766 --> 00:00:49,266

    Pull out a clean dust-free cloth from the plastic bag

    11

    00:00:54,166 --> 00:00:58,566

    Put the motherboard we need to clean on a corrosion-resistant rubber pad

    12

    00:01:03,166 --> 00:01:07,633

    Dip the brush into the PCB cleaner to clean the areas we need to clean

    13

    00:01:10,166 --> 00:01:13,066

    Then cover the surface with a dust-free cloth

    14

    00:01:14,200 --> 00:01:16,866

    Wash it with a dust-free cloth

    15

    00:01:23,433 --> 00:01:25,666

    Continue to dip in PCB cleaner

    16

    00:01:32,233 --> 00:01:40,300

    You will find that the dust-free cloth that was very white before will now have a lot of dirt and impurities on the surface

    17

    00:01:43,800 --> 00:01:46,633

    When cleaning the motherboard, if you simply use a brush to clean

    18

    00:01:46,633 --> 00:01:50,766

    It can only loosen some sundries and dirt

    19

    00:01:50,933 --> 00:01:52,200

    to make them apart

    20

    00:01:53,333 --> 00:01:56,000

    But the brush can't remove them directly

    21

    00:01:57,300 --> 00:02:00,200

    So we need to use a dust-free cloth to absorb

    22

    00:02:00,800 --> 00:02:02,266

    Remove some dirt away

    23

    00:02:03,700 --> 00:02:06,366

    This way, the motherboard will be cleaner

    24

    00:02:07,800 --> 00:02:10,733

    So much for dust-free cloth.Thank you for watching
