Delay time and the motor with the same parameters, with the bad,LED billboard, welding arm movements will be different, the same result in the quality of exception. 3. The second value is set properly: Strategies ---- reset the binary. 4. Inconsistent with the standard machine-conditioners. For example: when adjusting dispensing, the dispensing spring crushed, dispensing head that are not flexible,light signs, how to adjust parameters of the results of no use.
Another example is the set-hook claw, claw hook, the hook into and pop under the standard to transfer if the displacement, it is likely to cause material and stent deformation run. Another example is the pressure welding arm, if not at the standard to transfer,LED message board, it will also affect the solid crystal quality, but also with how adjust parameters to tune is not good. Fifth, a master process. Silver plastic tank cleaning is regularly cleaned. 2. Silver plastic choice is reasonable. 3. Whether workers wear gloves, masks work. 4.
Has solid crystalline materials, baking conditions, time and temperature. Sixth, to keep the environment to meet the requirements 1. Dust is excessive. 2. Temperature and humidity are in the standard range.
For the production of LED chip, the substrate material selection is the primary consideration. What an appropriate substrate should be used, need to request equipment and LED devices to choose. Generally have three kinds of materials currently available can be used as substrates: sapphire (Al2O3) silicon (Si) silicon carbide (SiC) sapphire substrates typically, GaN-based materials and devices, epitaxial layers grown on sapphire substrate mainly.
Sapphire substrate has many advantages: First, the sapphire substrate production technology is mature,menu board, good quality components; Secondly, the stability of sapphire good to use in high-temperature growth process; Finally, the sapphire of high mechanical strength, easy to handle and cleaning.
