The level of viscosity is of great concern to the smoothness or not of screen printing. Therefore, in the PCB ink technical documents and QC reports, the viscosity is clearly marked, indicating under what conditions, what type of viscosity testing equipme
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
A smart bracelet is usually composed of a radio frequency circuit unit, a clock circuit unit, a memory circuit unit, a sensor circuit unit and a main control MCU unit, etc., and the circuit PCB is usually concentrated in a small range, single-sided or dou
PCB circuit board is the basic electronic components of all electronic circuit design, and the design of PCB circuit board is also a must understand for makers. The role of PCB is not only to combine scattered components, but also to ensure the regularity
From the point of view of welding PCB design should pay attention to the problemsFrom PCB design to the completion of all components welding into a high quality circuit board, PCB design engineers and even the level of welding process, welding workers and
The function of this stage is to clean the welded interface of the weldment, and clean the oxide film and attached dirt on the interface.
Do not wire under the crystal oscillator to ensure that the floor is completely paved, and do not wire within the 300mil range of the crystal oscillator, which can prevent the crystal oscillator from interfering with the performance of other wiring, devic
Accumulated service for thousands of electronic enterprises, involving many types of automotive equipment and industrial control motherboard SMT processing services, products are often exported to Europe and the United States, quality can be affirmed by n
In the actual processing of damp MSD, is generally baked in accordance with the manufacturer's original packaging bag warning label baking conditions. For components manufacturers do not have corresponding requirements, it is recommended to use high tempe
Different products, the selected coil diameter is different, the opposite inductance, the DC resistance is not opposite. In high frequency circuit, DC resistance has great influence on Q value
