6.2Welding processVisually, with the aid of a magnifying glassThe solder joints should be smooth, firmly, and reliably connected, with no cold solder joints, weak joints, or burrs.

Packaging and transportation methods

1. Packaging: Each box should contain several connected pieces, with any remainder packed separately.

2. Delivery: Use express shipping or arrange for a dedicated person to deliver the goods to the recipient’s warehouse.

Note: During transportation, care should be taken to prevent moisture and dampness and to avoid compression and collisions to prevent the protection boards from deforming.
