In just one day, the vast majority of students have been able to disassemble and assemble several major parts, remove the gold finger oxide layer and clean the dust in the chassis.

Finally, the group was assessed, and finally 20 trainees were determined according to their disassembly speed, action specifications and accuracy.

The 20 trainees will participate in the follow-up learning because they will have to do a lot of cleaning up the old computers after dealing with the computers with minor problems.

Those old computers collected by Minsheng Company are not like these computers in Huaxia, and all kinds of accessories must be varied.

Not only are the shapes different, but there are also different interface types for the same type of components, which need to be understood and familiarized with first.

According to Wei Minsheng's requirements, at least they should be able to use the replacement method to find out the problematic components, and find the right components to replace, and it is best to learn simple system installation, and find the shortcomings of the computer through evaluation software, and use the appropriate components in their hands to optimize the computer.

Wei Minsheng believes that with the most direct learning materials and a large number of different types of old computers for them to practice, this goal is not so far away.

Due to the time difference between the two worlds, these twenty trainees who have only mastered simple maintenance skills are enough to handle the processing power of four hundred maintenance personnel in the real world, which should be enough at the initial stage.

With these pioneers, under the guidance of Huaxiaguo's enlightened policy and intuitive personal income, these 20 students will be the leader and drive a large number of hobbyists.

After everyone has been exposed to more electronic components and basic circuits and other related knowledge, when the conditions are ripe, we can try to train a group of maintenance talents for household appliances, so that those equipment and components that are damaged by individual components but still have a certain repair value can be brought back to life.

At the low end, we can also gradually train some disassembly talents of electronic components, according to the processing method of the assembly line in the real world, each person only disassembles the specified classified components.

In such a situation, there is no need for them to become generalists, only need to know and be familiar with the same component, such a job does not need to be trained for a long time to be competent, and prepare a talent reserve for a large number of e-waste disposal in the future.

Such talents can even control their literacy at about 1,000 words, which is the basic quality of a full-fledged member of the Chinese state.

When Minsheng Company's real-world e-waste recycling and treatment plant is completed, they can carry out primary separation and classification of those e-wastes that cannot be reused, carry out pre-treatment work before large-scale treatment, and remove those parts that cannot be processed in the automatic desoldering equipment first, so as to improve the efficiency of automatic processing.

For those electronic components that are removed in the automated desoldering equipment, they can be completely handed over to these junior workers for sorting and grading, such a basic job that even people with very little literacy can do.

Due to the advantage of labor costs, Wei Minsheng can establish a multi-level disassembly component assembly line sorting base in Huaxia.

If you can't read, you can give you something, you just need to take the thing that looks more like this thing from the conveyor belt in front of you and put it together, this is the first level of sorting.

This job is very simple, the salary of the job is calculated according to the average work efficiency, and it also participates in the adjustment of the "self-employed post".

The second level of sorting is handled by those who have a small knowledge of electronic components, such workers only need to be familiar with a certain type of electronic components, and they are only responsible for sorting the parts that are transmitted to their posts by different models, and at the same time weeding out the parts that were sorted incorrectly in the previous process.

The third level of sorting requires more skills, and on the basis of familiarity with all the components sorted out in the previous process, they must also know how to check whether the performance of these components is within the standard range through various instruments and equipment, and then remove those components that have been damaged and unstable.

Those electronic components that meet the standards and have stable performance will enter the special electronic component recycling warehouse of the electronic waste recycling and treatment plant of Minsheng Company, and will be classified and stored according to specifications and models.

Since the service life of most electronic components is more than 100,000 hours, these disassembled electronic components can continue to exert residual heat, which can be directly purchased by individuals or sold by the network to manufacturers who need to downgrade and use, and produce electronic products such as toys with short life cycles and no harsh requirements for stability.

In the real environment, in addition to those large household appliances, many electronic products are updated for about two years, so these recycled electronic components will not affect the use of electronic products.

Since the price of these recycled electronic components is generally only about half of that of new components, it can greatly reduce the cost of the manufacturer and reduce the expenditure of the end user without affecting the use effect.

As far as the environment is concerned, if old components such as capacitors can be downgraded, then the treatment of harmful substances such as cadmium and polychlorinated biphenyls contained in them will be delayed, which will indirectly reduce the pollution to the environment, thereby reducing the cost of environmental protection investment for the whole society.
