Safety Protection During the LED Light -emitting Diode Packaging Process

1. In the process of production, storage, transportation and assembly of LeD packaging safety, instrument, equipment, materials, and operators can easily generate thousands of voltage voltage due to friction. When the LED is in contact with these charges, the charged body will discharge through LED 2. Due to the high resistivity of semiconductor materials, the sensory charge generated by the chip during the production process is not easy to disappear. , Can generate a high electrostatic voltage. This voltage will generate a strong electrostatic damage voltage that is only hundreds to thousands of inner insulation or PIN in the inner insulation or PIN of a strong electric field to break through the LED. Practical effect. As shown in Figure 2-2, the damage of the LED internal chip caused by static or electrical release. Generally speaking, the smaller the size of the device, the smaller the electrostatic voltage you can withstand, the greater the static electricity threatening it. The damage of the LED internal chip caused by the static electrostatic release. During the process, the operator's activities are large and frequent activities, and there are many contacts with materials and devices. If static protection protection is performed in accordance with electrostatic protection during the operation, the accumulated static electricity will not be exported in time, and the LED will also cause LED Huge damage. Table 2-1 lists typical voltage on the human body. As can be seen from Table 2-1, in the process with relatively low relative humidity, it is extremely important to perform necessary static protection and strictly control the damage of the human body voltage to the device. However, human static electricity is easy to be ignored, and too many electrostatic protection measures are also easy to ignore. During the entire LED packaging process, all personnel who perform process operations must always keep the concept of static protection protection in mind.
