The comparison between design and wiring is a major error in the final stage of PCB design. So a number of things need to be checked again, such as device size, hole quality, pad size and review level.
provides circuit schematic design, SCM development, pcb Layout, board copying, high-speed pcb design, SI simulation analysis and pcb design related training. In order to share our customers' worries,
Layout is an important part of design. The result of layout will directly affect the effect of wiring, so it can be considered that a reasonable layout is the first step of successful PCB design.
For some simple products, PCB design may simply connect all the devices and networks accordingly. For high-speed circuit, RF circuit, PCB design directly affects whether the function of the product is normal, whether the product can meet the market requir
From the current situation, only our country has recovered the supply of products in a short time, accelerating the trend of domestic replacement of PCB industry.
Anti-interference directly reflects the performance and reliability of the whole system. For PCB design engineer, anti-interference design is the key and difficult point that we must master.
The layout should meet the following requirements as far as possible: the overall connection should be as short as possible, and the key signal line should be the shortest; High voltage and high current signals are completely separated from low voltage, l
The design of high frequency circuit PCB is a complicated process, which involves many factors, which may directly affect the performance of high frequency circuit.
Wiring is the general requirement of high frequency PCB design on the basis of reasonable layout. Wiring includes automatic wiring and manual wiring.
Every hole on PCB is called through hole. From the perspective of function, through hole can be divided into two categories: one is used as an electrical connection between layers; The second is used for fixing or positioning devices. If from the process,
Signal integrity circuit board design criteria include SI problems, pre-design preparation, cascade, crosstalk and impedance control, high-speed nodes, technology selection, pre-wiring stage, post-wiring SI simulation, post-manufacturing stage, model sele
The size and type of embedded circuits vary by microprocessor, component, and operating system, but most importantly is the complexity of the software, whose code ranges from a few hundred bytes to several megabytes.
