PCB nickel plating
Organic pollution of gold cylinder using carbon core continuous filtration, and add appropriate amount of gold-plated additives.
How to rely on long PCB for antenna design and prevent distortion on PCB board
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
PCB design electroplating process you know which some
Communicate electronic devices. Military weapon system, as long as there is integrated circuit and other electronic devices, electrical interconnection between them to use PCB, circuit board.
Why should PCBS be divided into digital and analog
The most critical problem is not to cross the divide gap wiring, once across the divide gap wiring, electromagnetic radiation and signal crosstalk will increase sharply. The most common problem in PCB design is EMI problem caused by signal lines crossing
What are the manufacturing methods of PCB
The gold plating of the plug is hard gold, wear-resistant, pluggable hundreds of times, requiring that the gold layer has a certain hardness, and the gold liquid in the gold groove contains trace cobalt (nickel, antimony) elements.
PCB test points and their importance to circuit board manufacturing
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.
The method of judging the quality of PCB circuit board
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.
PCB circuit board how to distinguish good and bad and detailed PCB copy board process
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
Ceramic board pcb board
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.
Overcome the challenge of alignment of multiple connector groups between PCB boards
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.
The four elements of characteristic impedance are developed in the manufacture of pcb circuit boards
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.
