Effectively improve the quality of LED solid-crystal several steps:

    A strict inspection station LED solid crystal raw materials
1. Chip: pollution, mainly as a pad, chip breakage, chip cutting sizes, chip cutting tilt.
Preventive measures: strict control of feed inspection, identify problems require suppliers to improve.
2. Stent: The main manifestations of Θ size and C size deviation is too large, frame rust color, frame deformation.
Incoming non-performing suppliers are problems, they should inform the suppliers to improve and strictly control the feed.
3. Silver glue: The main performance of the silver viscosity bad, use the period of more than, storage conditions, and thawing conditions and the de facto standard of not meeting.
Viscosity for the silver, the general assessment by the project put into production will not have too many problems, but is not to say that the kinds of silver sol is the best, if found to have an adverse occurrence, we can see will work re-assessment. While the other period of use, storage conditions, thawing conditions, and so are manipulated, as long as strictly in accordance with SOP operations, generally will not have too many problems.
Second, to reduce the negative human factors
1. Operators operating illegally: for example, do not wear gloves, silver and plastic removed from the refrigerator after thawing have not been directly on-line, as well as operating personnel are not operating according to SOP, or unskilled machine operators Dengjun will affect the quality of solid crystal.
Preventive measures: foreman strengthen management, operations staff by SOP operations, quality assurance personnel to strengthen audit, right machine unskilled personnel to strengthen education and training, there is no formal induction induction permits are not allowed.
2. Maintainer-conditioners inappropriate: response is to raise the technical level. For example, take a high degree of crystalline, solid crystal height, thimble height, some delay time settings, motor parameters, table parameters, setting, etc., required to adjust the standard to the best condition.
Third, ensure the machine does not appear ill
Main aspects of the performance of machine parts and accessories for the machine or mechanical structure, and knowledge systems, etc. caused by the bad quality of the impact of solid crystal. Must ensure that the various functions of machine is normal.
Fourth, the implementation of the correct method of adjustment machine
1. Not a good spot:
Spot re-proofing measures ---- to ensure the 3.1 line.
2. The parameters set incorrectly:
For example: picklevel, bondlevel, ejectorlevel delay time, motor parameters, Solvable gado a few steps and still can be done by more than a few steps, but the result is completely different. Is also a thimble height, when the smoke can not afford to chip, it was energetically parameters, but not to consider whether the blunt thimble off or cut off, resulting in chip breakage, Θ angle offsets and so on. Delay time and the motor parameters with the same, with the bad, welding arm movements would be different, the same quality caused by abnormal.
     3.2 values are set incorrectly:：
Measures ---- reset binarization.
4. Inconsistent standards for machine-conditioners.
For example: when you tune dispensing to dispensing spring crushed to death, a little flexibility in dispensing heads are not, then how to tune parameters of no use. Another example is the set-hook claws, hooked claws on the hook under the chin and pop-up displacement if the standard to emphasize that very easily lead to run material and stent deformation. Another example is the pressure welding arm, if not standard to transfer, it will also affect the quality of solid crystal, but also how to use parameters are also adjusted well to the tune.
5, master production process
1. Silver glue tank cleaning is regularly cleaned.
2. Silver glue choice is reasonable.
3. Operations staff is wearing gloves, masks work.
4. Has been solid crystalline materials, baking conditions, time and temperature.
