The company gives full play to its competitive advantages in scale procurement and quality control, and has signed long-term cooperation agreements with many electronic component manufacturers at home and abroad and around the world to ensure the quality
In PCBA processing, automatic optical inspection is usually set at the last step of the SMT production line, and it is necessary to detect the defects of the product after the completion of the SMT processing process.
It is a welding method that the welding end face of the components and the PCB welding pad are coated with paste solder and assembled together, heated until the solder is melted, and then the welding area is cooled.
Aluminum is a very attractive material with abundant resources, low cost, excellent thermal conductivity and strength. In addition, it is very environmentally friendly and can be used on most metal substrates or metal cores. Due to the advantages of econo
The frequency of the digital circuit is high, the sensitivity of the analog circuit is strong, for the signal line, the high-frequency signal line is as far away from the sensitive analog circuit device as possible, for the ground line, the whole PCB has
found a short circuit phenomenon. Take a board to cut the line (especially suitable for single/double board), after cutting the line, each part of the function block is powered separately, and gradually eliminated.
In order to make the test as high as possible failure coverage, in the design stage must pay attention to the selection of components and PCB layout, unfortunately, the actual situation is not always the case, rush to market and nervous development often
The Chinese name of SMT chip processing (PCB) is called "printed circuit board", also known as printed circuit board, printed circuit board, is an important electronic component, is the support body of electronic components, is the provider of e...
In the rapid development of science and technology today, a variety of high-tech electronic products emerge in an endless stream, which makes the demand for printed circuit boards increase sharply, manufacturing difficulties are becoming higher and higher
Challenge: Equipment is expected or required to maintain as uniform surface pressure as possible to improve the quality of processed products
Paneling via flange wiring of a perforated material bridge: This process is similar to the simple flange wiring described above. However, the material bridge here has additional holes drilled, which greatly simplifies the separation process and also provi
Practice has proved that it is difficult to find each and every solder paste fouling only by sampling the printed circuit board samples. Only 100% inspection of all circuit boards can ensure greater inspection coverage, thus enabling statistical process c
