Thermal diffusion is treated very effectively in the circuit design scheme, thus reducing the module operating temperature, extending the service life, and improving the power density and reliability.
The display covers the entire supply chain of circuit board and electronic assembly, including circuit board manufacturing, equipment and raw materials for circuit board and electronic assembly.
The above is for everyone to share the PCB board interconnect high frequency PCB design skills, if you are familiar with these methods, you can understand the use of back copper-covered coplanar microstrip design than strip line design is more economical
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 addition to labor costs can not be compressed, production efficiency will also be seriously reduced, SMT proofing small batch processing due to a small amount of production line just started to stop, which undoubtedly has a great impact on production e
the circuit board must be flame resistant, can not burn at a certain temperature, can only be softened. At this time, the temperature point is called the glass transition temperature (Tg point), and this value is related to the size and durability of the
In the first manned Apollo spacecraft, for example, an electrostatic discharge caused an explosion that killed three astronauts. Electrostatic discharge (ESD) in the process of gunpowder manufacturing, resulting in explosion casualties often occur.
The soft plate is also like the hard plate, and can be made of plated through holes or surface adhesive pads for through holes insertion or surface adhesive installation. The surface of the board can also be attached to a soft protective and solderproof C
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.
Look at the PCB to see if there is scratch where the patch element falls off. Scratch where the PCB patch element falls off will also make the adhesion of the green oil insufficient, which can cause the patch element to fall after the PCB has passed the t
Once encountered because of the poor environment, the dust inside the display is thick, and when the weather turns tide, the circuit board is caused by short circuit ignition and damage to the display.
high reliability PCB will strictly define the shape, hole and other mechanical characteristics of the tolerance, very good to improve the size of the product quality - improve the fit, shape and function. thin solder resistance layer can lead to adhesion,
