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
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.
Cost = materials + labor + manufacturing expenses, which materials include? Including raw material control, water and electricity control, scrap rate control, process control.
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
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.
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.
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.
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.
The arrival of the intelligent age, not only brings convenience to people's lives, but also has a profound impact on all industries, so the PCB copy board, design put forward higher requirements, professional PCB copy board companies should continue to im
The adoption of high speed PCB design means constitutes the controllability of the design process, only controllable, is reliable, can also be successful!
The main reason of reflection signal: too long running; Transmission lines with unmatched terminations, excess capacitance or inductance, and impedance mismatches.
The generation of grooving can be summarized into the following two cases :1. Grooving caused by power/ground plane segmentation; 2.the through hole is too dense to form grooves.
