Talking about the precautions of R & D model patch
With the development of social economy and technology, electronic products have become popular in our lives, which makesR & D model patchThe market has been greatly developed. Many people may be unfamiliar with the sample patch. In fact, it is very common in life. Almost all electronic products contain it. It can be said that it is the brain of all electronic products. The development of sample patches is simply a generation. Some small and medium-sized electronic product manufacturers without R&D capabilities conduct circuit board design and trial production.
Pay attention to the following matters when developing sample patches:
First, in order to prevent the wrong placement of the R&D template patch, the number of bom must be analyzed first, and then the patch map is corresponding to the components with the same parameters, and the pictures are drawn in different colors.
The second is that in the process of R&D template placement, different components should be put in according to the different personnel. The personnel in the next process need to check the components and positions of the previous personnel’s placement. If problems are found, they must be corrected in time. . At the same time, the method of microscopic inspection is used for inspection, and a multimeter will be used for measurement.
The third is that the soldering process of the R&D sample patch must be very secure. There are usually three more critical parts, such as solder paste printing, chip placement and furnace heating. Every step must ensure that there will be no problems, and the person who puts in the chip needs to select people who have gone through many plates, and the whole process needs to be very strict.
The process of developing a model patch is actually a process of designing and processing the patch. Therefore, in addition to the above precautions, it is also necessary to pay special attention to a series of design issues such as whether the design of the patch meets the needs of customers, whether the circuit drawings of the patch design are original drawings, and so on. At the same time, attention should also be paid to the processing and production of R&D prototypes. Time is a matter of efficiency, because in the electronics industry, time is life.
