2014 is coming to an end, and the end of the year and the beginning of the year are generally the time for the next year's product planning and technical planning. For lighting companies, it is the primary task to find a few more reliable packaging factories, so various audits began. As an engineering technician in our lighting factory, how can we judge the strength and stability of a company from the appearance? In addition to the ISO document, what details do you need to see?
1. Clean clothing: LED packaging factories need dustproof and antistatic production and inspection areas. Protection of workers: Whether the clean clothes are connected or separated, whether there are grounding wires and static wires. In fact, clean clothing is only a way of product protection, and does not have much impact on the reliability of the product. By requiring workers to wear clean clothes, all employees respect the work of themselves and others, and recognize the products they produce, and provide employees with pride. This is very important. Once people think that the work they do makes sense, they will work more seriously.
Second, the station's settings: There are various stations set to "one" shape, but also set to "U" shape. Mainly to make the materials in the workers and work easy to transport, the shortest path is the key indicator every time. As a packaging factory, the location of the oven room is particularly important, because the oven room is the intermediate station of the solid crystal and the wire, and the temperature of the oven room is high, which also affects other processes. Is there an isolated area for enhanced dust removal in the dispensing station? With the control of the powder and powder, this process affects the color temperature distribution of the LED, and has not yet been automated. According to what I have seen, whether it is a large capacity or a famous one, several technicians are operating around the electronic balance. Whether there is spilled material around the machine for splitting the color separation is very easy to cause mixing.
Third, the test record: the SOP file of the packaging factory stipulates that the tensile force of the welding wire and the thrust of the solid crystal are tested every few hours. Is there any work? What are the means and equipment for testing? Many small factories use manual dynamometers to test, which is easy to cause errors. It is recommended to use an automatic push-pull tester to analyze the effective model. According to the regulations, according to the regulations, the orderly reports on the surface of the factory's serious attitude.
Fourth, product development engineering records: a product from scratch, how to specify the use and verification of various materials? The materials used in the packaging plant are indistinguishable from the packaging factory. This requires the engineers of the packaging factory to take each material seriously and verify the stability of the material from long-term experiments. If you change the main materials such as glue, phosphors and even chips every three or five months, it will easily cause big problems.
V. Strength of the laboratory: The packaged device always has to test the items of high temperature, high humidity, high temperature aging and cold volume impact. Does the laboratory corresponding to the packaging factory have this strength to do it, and each batch is strictly in accordance with this? There are many companies whose product specifications seem to have any tests. As a result, there is no experimental equipment. Do you not shoot such a packaging factory?
Overall: don't look at fame, look at strength! Don't look at the machine, look at the instrument! The quality, heavy detail packaging factory is the king!
