The two major difficulties in the field of microelectronics are the processing of high-frequency signals and weak signals. The same principle design, the same components, different people produced PCB circuit boards will have different results.
A protective coating is a polymer film applied to the PCB surface to protect the PCB board and its components from corrosion and environmental contamination.
The temperature resistance test of PCB circuit boards is to prevent adverse reactions such as board bursting, foaming and delamination at excessively high temperature, leading to poor product quality or direct scrap, which is a problem that needs to be pa
With the wide application of wireless communication technology in various fields, high frequency, high speed and high density have gradually become one of the development trends of modern electronic products.
When adopting this method, it is necessary to ensure that the width of the bridge between the two ground is equal to the width of the IC, and that no signal line can cross the division gap.
Modern wireless applications require sturdy antennas, which often means a long printed circuit board to integrate and support these applications. Antenna designs can make or break your application, but relying on long PCBS can help you get the job done ri
Automated testing is essential to validate the manufacture of printed circuit boards. The bare board test will check that the wood-based board has good connectivity, while the ICT and fly pin tests will verify the board assembly and welded connections.
Now there are many ways to layer, there are potions corrosion, tool stripping, but it is easy to put the layer over, lost data. Experience tells us that sandpaper is the most accurate.
the general double panel copying board is much simpler than the multi-layer copying board, multi-layer copying board is prone to inaccurate situation, So the multilayer board copy board to be particularly careful and careful (which internal through holes
the dielectric constant is small, can be used in high frequency. If applied to the electronic communication industry, it can greatly reduce the signal loss rate. The price of ordinary PCB board on the market will vary according to different materials.
The procurement of certain PCB boards is controlled only by the specifications embedded in the Gerber packet. PCB boards can be built from these packets, regardless of mechanical tolerances.
Although the miniaturization trend makes it more challenging, it is possible to use multiple connector groups on two PCB boards by using best design practices.
