PCBA processing patch processing small knowledge
The surface packaging technology is analyzed and studied for assembling the circuit board. And then we put it together and we make a finished product. That is to say printed circuit board blank after the patch
Signal integrity design of PCB for Gigabit equipment
In the design of PCB boards for gigabit devices, a good signal integrity design requires the engineer to consider all aspects of the device, transmission line interconnection scheme, power distribution, and EMC.
High - level circuit board hub production process control
High TG, high speed, high frequency, thick copper, thin dielectric layer and other special materials are used in high-rise board, which puts forward high requirements for inner line fabrication and graphic size control.
How to maintain PCB circuit boards to extend the service life?
With the rise of the electronic industry, circuit board production and development has become a more and more important part of PCB proofing a circuit board is not simple, easy to say.
Application of Sequid TDR to PCB impedance testing in Internet of Things devices
The impedance test template can automatically generate a custom impedance template that changes with time according to the circuit characteristics on PCB, as shown in Figure 5. In this way, the special PCB wiring can be accurately judged and detected, suc
PCB circuit board factory introduces PCB light curing
At present, for PCB curing, the most suitable use or UV light source, because UV light source has the characteristics of other mercury lamps do not have, just take the light source, UV light source is a cold light source, the curing principle is that the
PCB copy board (circuit board copy board) copy board analysis panoramic camera parking technology
The mechanical driving part is driven by the CAM spindle to drive the feeding mechanism, and the striking arm of the feeder is quickly found. The ratchet connected with it drives the component braid forward a distance through the connecting rod, and drive
Chemical deburring process of the latest PCB circuit board
In addition, the process can prevent hydrogen embrittlement, because the process does not form a closed space, which helps to prevent acidic materials during plating from being trapped inside the workpiece, thus preventing hydrogen elements from entering
PCB manufacturers share the functions and precautions of electrolytic capacitors
In the power supply circuit, the positive electrode of the electrolytic capacitor is connected to the output terminal of the power supply when the positive voltage is output, and the negative electrode is grounded.
What convenience will Bluetooth module bring to the hardware
Especially for RF performance, customers do not need to invest manpower and material resources for antenna matching design and anti-interference design of PCB research and development and trial production.
Right-angle routing, differential routing and serpentine routing in PCB LAYOUT
Layout is one of the most basic skills of PCB design engineer. The quality of the wiring will directly affect the performance of the whole system, most of the high-speed design theory will be finally realized and verified by Layout.
