when the customer requires the top bottom to write copper words, line copper word line width: HOZ base copper: character width of more than 8mil, height of more than 45mil; 1OZ base copper: more than 10mil character width; Height above 50mil. At the same
Design data output: PCB source files, Gerber files, assembly files, steel mesh files, structural files, etc. After the PCB Layout design is completed, our engineers will conduct mutual inspection, including DFM inspection, QA inspection, EMC inspection. A
Reminder: Try to provide a special wiring layer for key signals such as clock signals, high-frequency signals, and sensitive signals, and ensure its minimum loop area. The signal quality is guaranteed by means of shielding and increasing safety distance.
There are several categories of transmission line technology, the earliest transmission line is the coaxial transmission line invented by Oliver Heaviside to solve the long-distance transmission problem of the telegraph at that time, and the common forms
The design process begins with circuit design. The first thing you need to do is take out a document called a schematic. You can think of it as a blueprint that shows all the components and how they communicate in detail.You can design circuits on a PC us
It has been measured that a pass hole can bring about 0.5pf of distributed capacitance, resulting in a significant increase in the delay of the circuit, and reducing the number of pass holes can significantly improve the speed
Cross-segmentation may not be relevant for low-speed signals, but in high-speed digital signal systems, high-speed signals take the reference plane as the return path, that is, the return path. When the reference plane is incomplete, he following adverse
Long track and zigzag track will affect the signal quality, resulting in signal distortion and interference. In order to avoid this situation, it is necessary to avoid the occurrence of too long and too curved. For some lines that need to be bent, excessi
For those devices that are easy to produce noise, small current circuits, large current circuit switching circuits, etc., should try to keep it away from the logic control circuit and storage circuit (ROM, RAM) of the single chip computer, if possible, th
Through the above analysis of the parasitic characteristics of the hole, we can see that in high-speed PCB design, seemingly simple holes often bring great negative effects to the design of the circuit.
To sum up, to choose an excellent PCB design company, you need to consider the strength of the company, customer reputation, service quality and price, after-sales service and other aspects. In the selection, you can according to their actual needs and bu
Surface mount testing can effectively test surface-mount components on the circuit board, such as chips, capacitors, resistors, etc. In addition, when performing surface mount tests, it is also possible to check whether the solder joints on the circuit bo
