Esd Protection For Mp - Realtek RTL8762C Hardware Instructions

15 ESD Protection for MP


The machine that brushes the solder paste needs to be grounded.

The PCB to be processed needs to be placed on the insulating tray. If it is placed on a metal
plane or a tabletop, the plane (table) surface needs to be grounded.

On-site personnel need to wear a grounded electrostatic wristband (effect of wireless
wristband anti-static is limited, which is not recommended to wear)

Avoid using mirror board.

The side where IC is to be placed should be left until the second time of PCB SMT to reduce
the number of times that IC touches the metal or the machine.

If the operator needs to visually check PCBA, the PCBA needs to be placed on the insulating
plane. The operator needs to wear an electrostatic wristband, and metal tweezers used need to
be covered with an insulating sleeve.

After the IC is processed by the tin furnace, the operator needs to place the PCBA on a
separate insulation tray.

Rework workbench, welding torch, electrostatic wristband and operation table mat need to be
grounded.

The SMT machine is strung together by metal wires, and then connected to the earth by
pipelines.

Persons who could get contact with the PCB should wear non-conductive finger sleeve.

When correcting the positions of components or boards, do not touch the IC pins with metal
tweezers.

Apply antistatic liquid on loading board regularly.

PCBA semi-finished products must be placed on an insulating tray with separate grids. Only
one PCBA per grid. In order to avoid CDM collision, it is prohibited to stack PCBA.
