Chapter 117: The Importance of Test Data
"Let's not discuss this for the time being, why don't we go to the testing line and have a look......"
Industrial relocation is a very big test for every factory owner, and since Cai Zhiming is unwilling to say more, Yao Fei will certainly not delve into the bottom line.
"Okay, the testing line is at the back of the assembly line, we took the equipment you left behind last time as the core, and set up a testing team, and now the inspector is still an engineer transferred from your factory.
Our factory has sent or recruited more than a dozen people to follow behind as apprentices, and it is troublesome for them to take two with them, and when they can carry out testing operations independently, it will be considered a teacher......"
Enterprise transformation is not a trivial sentence that can be transformed immediately, but a more contradictory thing, especially for a relatively successful enterprise like Sunrise Toy Factory.
In the transition period, enterprises usually inevitably have to experience a series of problems such as declining profit margins, financial difficulties, and the technical level of production personnel.
But even so, at the beginning, the poor production environment and the lack of technical skills of the production workers also made them unwanted, until now they have finally begun to get on the right track.
As for profits, didn't you see that they have just begun to produce until now, they have been constantly throwing money into it before, saying that Cai Zhiming has hollowed out his family for this transformation, which is not blind at all!
"What are the results of your board voltage detection?"
The first testing process is voltage detection, if the detection voltage value is more than 0.1V different from the design standard voltage value, then it is a non-conforming product.
"Boss, according to the current statistical data, the pass rate of voltage detection is 94.7%, the voltage difference is 4.6% within 0.15V, and the difference is only 0.7% outside 0.15V......"
Yao Fei, the engineer in charge of testing, knew that he was one of the people he brought from the branch last time, and the other party was obviously satisfied with the result when he said this.
94.7% of the voltage detection pass rate is not much, that is, another unqualified product name, but only relative to the standard of CITIC Communications, although the generation of a large voltage difference will definitely affect the service life of the product, but this certainly does not need to be recycled as a waste product as before.
As long as there is no problem with the functional testing and the product can be used normally, the factory will definitely be able to dispose of these "substandard products" at a slightly lower price.
"What about chip component testing?"
"Everything works!"
"Program Programming Integrity Test?"
"Everything works!"
"Process testing, is there any false welding?"
"The pass rate is 99.2%, and the other 0.8% only show slight virtual welding and overwelding, which is only two or three percentage points away from the standard parameters we require......"
There is only a difference of two or three percentage points, and it has passed the voltage detection test, which is almost no problem, but Yao Fei has always pursued high standards and strict requirements, and any standard must be based on science.
Even now, Yao Fei can only say that he is a small step ahead of Panasonic and Motoroloda, the two old pager manufacturers, in the letter pager, and only in the function of the product, it must be a matter of time before someone catches up.
"What are the results of the aging test?"
For the functional body of the pager that has passed the test, it is to assess the performance of the whole machine, aging can make the defects of the product exposed before leaving the factory, such as the reliability of the welding joint, various defects in the design, material selection and process of the product, and the aging test can make the product performance enter the stable range before leaving the factory, which can greatly reduce the repair rate.
This is the most important process of detection, but also the most critical process, it is not only a summary of the previous testing process, but also directly related to the vital interests of consumers, very test the moral conscience of an enterprise, just like the kitchen oil in the hotel.
"The pass rate of one-time testing is currently only 72.8%, 16.6% of qualified products for secondary testing, 8.9% of qualified products for third testing, and rework for more than three tests for unqualified products, with a failure rate of 1.7%!"
When Yao Fei asked about his previous process process inspection, the tester in charge of the aging test had already prepared his statistical data, just waiting for Yao Fei to ask him.
"How many products are there that have passed the test at present?"
Passed the aging test, then it means that the product is qualified, because the next process of shell assembly, compared to the welding and testing of this assembly line, there is no difficulty at all, at most it can only be said to be a meticulous job, such as how to fix the LED LCD screen, how to pad the shockproof rubber sheet, how to place the parts connected with the circuit board neatly and orderly into the small shell according to the requirements.
"Wait a minute, let me see, there are currently a total of 1,683 products that have passed the test, of which only 594 were last Monday, and the remaining 1,089 were manufactured within this week......"
After carefully looking at the statistics in the notebook next to him, he immediately gave extremely accurate data.
"How many units were tested last Monday, how many units were tested this week, and what is the pass rate of testing?"
It seems that the soldering skills of the workers on the assembly line have improved very quickly, and today is only Thursday, but they are close to completing the production of last week's cups, and at this rate, the first batch of 3,000 pagers can be delivered on time by the end of next week.
"A total of 675 units were tested last week, and 1,164 units were tested this week, with a test pass rate of 88% and 93.56% respectively, and the test pass rate increased by 5.56%."
The other party was very smart and quickly understood what Yao Fei meant.
"Boss Cai, according to the current data, your situation here is very optimistic, not only the production speed has increased rapidly, but the efficiency has also shown a good growth momentum along with the speed.
No, according to the current situation, I have to continue to add some burden to you, according to the next month's order plan we agreed, you only need to deliver 4,000 pagers, why don't we raise this number a little more now and change it to 5,000 units? ”
Although the price of the pager launched by Yao Fei is not low, the number of 3,000 units will definitely seem a drop in the bucket compared to the 6 million Hong Kong people, and the supply will exceed the demand.
"Brother, you can rest assured, we will never hold you back because of our own production problems, even if you want 6,000 units, brother, I will go out of my way, and strive to build you a ......6,000 units."
