The circuit board on which the PCB is based
The next stage is product implementation. At this stage, product documentation is collected and compiled, including all manuals, catalogs, and related product documentation.
How to deal with the phenomenon of tin tip in PCB wave soldering
Cause of the tin tip phenomenon in wave soldering long pin components: Most of the flux on the circuit board will be washed away, leaving flux between the PCB board and the tin wave. When the PCB board leaves the tin wave, the flux left on the PCB board p
PCBA manufacturers teach you to judge PCB quality
Debugging circuit board problemOne: measurement circuit board voltage method:Two: circuit board signal injection method:Three: circuit board mode method:Circuit board configuration needs to solve certain instruments for debugging, but also need long-term
PCB design Layout Guide for engineers
This requires careful management of library components, CAD Settings and parameters, component placement, wiring, and power supply network (PDN) design. In addition, layout designers must ensure that their work is fully documented and that the final produ
PCB board each layer function
The signal layers are all layers with electrical connections, which is the actual copper layer. Intermediate layer refers to the intermediate plate layer used for wiring, in which the wire is distributed.
How does PCB design avoid crosstalk
Cost = materials + labor + manufacturing expenses, which materials include? Including raw material control, water and electricity control, scrap rate control, process control.
How can PCB design be optimized to meet lead-free requirements
At present, lead-free environmental protection is a technical challenge for PCB manufacturers and PCBA manufacturers. A lot of manpower and material resources have been spent on PCB design. The following progress has been made: 1. Improvement of the speci
PCB seven surface treatment technology
The copper layer on the PCB is easily oxidized, so the resulting copper oxide layer can seriously degrade the weld quality, thereby reducing the reliability and effectiveness of the final product.
PCB circuit board conduction hole must plug hole, after all what knowledge?
In order to meet customer requirements, the pass-through hole plugging process is varied, the process is particularly long, the process control is difficult, often in hot air leveling and soldering experiment oil loss; Oil explosion after curing.
How to design PCB crystal oscillator
All the work of the digital circuit is inseparable from the clock signal. The crystal oscillator directly controls the whole system. If the crystal oscillator does not operate, the whole system will be paralyzed.
What do PCB laminated design need to pay attention to?
In terms of manufacturing cost, with the same PCB area, the cost of multilayer boards is definitely higher than that of single and double layer boards, and the more layers, the higher the cost.
