🔍 Key Concepts

• Proper handling of printed circuit boards (PCBs) to avoid physical damage and electrostatic discharge • How edge card connectors engage the contacts along the long edge of the board • The effect of different rocking directions and hand positions on connector stress and board flexing

💭 Think About

• Which motion will pull the board straight out of the edge connector contacts instead of twisting or flexing the board excessively? • How does holding only the corner edges versus the top and bottom surfaces affect the risk of damaging components or traces? • If the board is inserted horizontally along its long edge, which way should you gently rock it to reduce stress on the connector and PCB?

✅ Before You Answer

• Make sure the technique minimizes bending or flexing of the board itself. • Confirm the method avoids touching components and circuitry as much as possible, focusing on edges or corners. • Check which option describes a slow, gentle, controlled removal, rather than a fast or forceful motion.

Grasp the board with your thumbs and fingers placed on top of and under the board and remove it rapidly with one continuous motion.

Handle the board at the corner edges and apply pressure while you rock it up and down gently while pulling.
