Big data and artificial intelligence are making humans more dependent on electronic systems, and will make reliability deficiencies even more deadly. At DesignCon 2020 recently, I had the opportunity to learn how ANSYS enables engineers to design highly r
In the ground plane segmentation and signal routing, the distribution of ground plane and important signal routing should be taken into account to prevent the problems caused by the ground plane slotting.
The following is my personal opinion and control method of the hole without copper open circuit. The reason for the absence of copper in the pore is nothing more than。
These organic compounds, such as derivatives of caprolactam, may participate in REDOX reactions, stripping away the atomic hydrogen before forming hydrogen molecules, preventing bubbles from forming. The reduced pitting additive is reoxidized at the anode
The removal of copper from the through-hole can be caused by chemical factors, such as etching, or mechanical causes, such as blow-holing, stress cracking, or deposition detachment.
manual wiring is and will be an important process in PCB design. Manual wiring is helpful for automatic wiring tools to complete the wiring work. By manually routing and fixing the selected net, a path can be formed for automatic routing.
PCB demand in the computer field can be divided into PC and service/storage and other segments, in which the PC market is basically saturated and the growth rate is relatively slow, while the service/storage market scale is growing rapidly.
PCB circuit opening and short circuit are the problems encountered by PCB manufacturers almost every day, which has been troubling the production and quality management personnel.
Too low density of alkaline etching solution will aggravate side erosion, choosing etching solution with high copper concentration is very beneficial to reduce side erosion.
high heat dissipation devices in connection with the substrate should be able to reduce the thermal resistance between them.
In the future, with the emergence of new demands for automotive electronics, data centers and artificial intelligence, PCB industry will usher in new growth points.
Any other design tricks such as considerably reducing the length of the goldfinger, terminal matching, Daisy chain connections or branch connections are designed to ensure that the signal sees a consistent instantaneous impedance.
