Unpacking a Card

Unpacking a Card

Context

A card is packed in an ESD bag, which is placed in a carton with foam materials.

  • Electronic devices are vulnerable to electrostatic discharges (ESD). Before touching a card, wear ESD gloves or an ESD wrist strap (with the other end in an ESD jack). Do not touch electronic components on the card.
  • If a card is moved from a cold, dry place to a warm, humid place, wait more than 30 minutes before unpacking the card. Otherwise, moisture accumulated on the card surfaces will damage the card.
NOTE:

The desiccant in an ESD bag can keep items in the ESD bag dry.

Tools

  • ESD wrist strap or ESD gloves
  • Utility knife

Procedure

  1. Inspect the carton of the card. If any damage is found on the carton, or the label on the carton is damaged, contact the equipment supplier immediately. If the package is intact, go to the next step.
  2. Wear ESD gloves or an ESD wrist strap (with the other end inserted in an ESD jack).
  3. Open the carton.
    1. Cut the pressure-sensitive adhesive tape with a utility knife. See callout 1 in Figure 6-2.
    2. Open the carton and remove the foam materials. See callout 2 in Figure 6-2.
    3. Open the ESD bag and take out the card. See callout 3 in Figure 6-2.
