The internal network table is the network table used for wiring inside the PCB system after modification according to the imported external network table. Strictly speaking, these two types of network tables are completely different concepts, but the read
At present, with the development of printed circuit boards in the direction of high density and high precision, more stringent requirements have been put forward for copper sulfate plating process.
In the past decade of research on PCB copying board and chip decryption, Hongyunlai reverse R&D engineers have accumulated rich experience in board copying and decryption, and have maintained long-term friendly cooperative relations with many domestic...
Formation mechanism: During reflow welding, the heating of chip components is heated at the same time. Generally speaking, the pad with the largest exposed area is first heated to a temperature above the melting point of the paste. In this way, one end of
Radio frequency and microwave signals are very sensitive to noise-much more so than ultra-fast digital signals. This means that you need to work hard to keep noise, ringing, and reflection to a minimum, while carefully handling the overall system
When the proofing is completed, we should carefully check to see if there are some problems in it. We must have a very appropriate check for the specific situation in advance and consider it in a targeted way. After these aspects, we can harvest better re
If you want to do these planning things well, you should have a correct understanding of the whole production process from a number of different angles
Power layer copper is a faster and easier option for most PCB design software. By sharing a large number of wires, maximum efficient current with minimum impedance or voltage drop is guaranteed, while providing an adequate grounding return path.
Mentor's products are BoardStation(EN) and Expedition PCB(WG) and acquired PADS(PowerPCBs). EN is the legendary PCB invincible master, those who only consider the duration of the project without considering the cost, always do 8 ~ 12 layers of PCB communi
The de facto industry standard in high speed plate design. It's awesome in every way. PCB Layout tool is absolutely first-class, a little familiar with no longer want to use other tools, wiring super cool. Simulation is also very cattle, have their own si
PCB circuit board needs reasonable design and layout of components, in order to better play out the functional advantages of the circuit board.
