Checking the Boards

Checking the Boards

Clean the chassis and cabinet before installing the boards. Wear an antistatic wrist strap and remove the board from the antistatic package. Check whether the board name is consistent with the identifier on the package box, and whether any device is damaged or any component is missing.

Check pins on the backplane of the chassis. The pins should be kept straight, orderly, and clean. For the pins bent in the board slots on the backplane, repair them.

The boards are sensitive to Electrostatic Discharge (ESD). When handling boards, observe the following rules:

  • Check whether the device is securely grounded against requirements.

  • Wear an antistatic wrist strap during the installation.

  • Ensure good contact of the metal tab of the wrist strap with your bare skin. Insert the other end of the wrist strap into the grounding point on the device.

  • Ensure that the wrist strap works in the normal state. Its resistance value must be between 0.75 megohm and 10 megohm. If the service life (usually two years) of the wrist strap expires or the resistance value fails to meet requirements, replace it with another one.

  • Avoid touching the board with your clothes, because the touch generates static electricity that is beyond the protection scope of the wrist strap.

  • Wear antistatic gloves and place the board on an antistatic pad when replacing the chip of the board. Use antistatic tweezers or extraction tools to replace chips. Do not tough chips, circuits, or pins with your bare hands.

  • Keep the board and other ESD sensitive parts to be installed in antistatic bags. Place the removed boards and components on an antistatic pad or other antistatic materials. Do not use non-antistatic materials such as white foams, common plastic bags, or paper bags to pack boards or let them touch boards.

  • Wear an antistatic wrist strap when operating the ports of boards because they are also ESD-sensitive. Discharge the static electricity of cables and protective sleeves before connecting them to the ports.

  • It is recommended that you reserve some materials that can hold boards such as vacuum formed boxes and antistatic bags in the equipment room for later use.
