Can cable trays be used for electrostatic discharge bridging
Just stick an 2 layer antistatic mat on the aluminum trays, it will make good contact with the boards and prevent any static from building up in the transport, as well will slowdown discharge. You can also refer ANSI/ESD S20. 20 (Chapter 8: ESDs item Handling). The ESD workpiece carriers reliably prevent the generation of electrostatic charges and discharge existing charges in a controlled manner. The rapid discharge can be harmful to some components, and could possible cause other issues if the Aluminum trays are used after test where capacitors may hold a charge and then short into other parts, cause sparks, etc. Even very small voltages that are not noticeable to humans can destroy microchips or circuit boards. These trays are made from materials that have conductive or dissipative properties, allowing them to safely dissipate any static electricity that may build up.

Electrostatic Discharge Prevention for Laser Diodes
These steps can prevent ESD damage: Use the laser only in a static-free work environment. Work on a grounded workbench or surface with anti-static floors and a case ground. It is said that there are two types of researchers—those who have destroyed laser. 3-1. LD Drive Circuit Design Method 3-4. For greater protection, use a dedicated grounding device, an air ionizer designed for. This document describes electrostatic discharges (ESD)/ESD tests (operation of MM/HBM/CDM/IEC61000-4-2)/operation of ESD protecting diodes (ESD pulsing/normal operation)/selection methods/caution in designing (laying out) boards/Maximum ratings/electrical properties as described in the datasheet.

60R optical cable splicer does not discharge
The fusion splicer indicates that the discharge intensity is not enough The cause of the fault can be analyzed from the following points： (1) Electrode discharge intensity coefficient is too low. (2) The electrode discharged too many times and the surface was oxidized. The 90R will start to warn you to replace the electrodes and you should follow the “Replace electrodes” procedure in the maintenance menu. In this expert. In general, fiber fusion splicer could calibrate its ARC by temperature, humidity and air pressure automatically. But the aging and dirty condition of the electrodes will also cause the change of discharge intensity, and the discharge center will be shifted relative to the position of optical fiber. Do not disassemble or try to repair the fusion splicer or its accessories without authorization.
