How to prevent SMD IR LED Emitter and IR Receiver from being damaged during transportation?

We know that SMD IR LED is a very fragile thing, but because the distance between the IR LED Emitter chip processing factory and the buyer may not be very close, the transportation of IR LED has become the biggest problem for buyers. For SMD IR There are many issues that need attention in the transportation of fragile products like LED:

1. The stack height of SMD IR LED Emitter and IR Receiver should not exceed 3 layers during transportation to prevent falling and crushing.
2. During the transportation of SMD IR LED Emitter and IR Receiver, it is strictly prohibited to transport them together with dangerous goods;
3. SMD IR LED Emitter and IR Receiver need to be moisture-proof and vibration-proof during transportation, and it is strictly forbidden to throw it high.
4. During the transportation of SMD IR LED Emitter and IR Receiver, it is strictly forbidden to stack other goods on the upper layer of the outer box.
