The PCB routing density is increasing, so the PCB routing design is particularly important.
With the development of large-scale integrated circuit and super-large scale integrated circuit, the multilayer printed board (PCB) will be used more and more.
Rf/microwave design considerations
The microstrip line consists of a fixed length of metal or wire and the whole or part of the ground plane located directly below it.
Analysis of main characteristics and cost of flexible circuit board
The insulating substrate may be polyimide, polyethylene terephthalate, arylamide fiber ester and polyvinyl chloride.
5G drive PCB volume and price rise
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.
Interesting topic
The UV laser precisely cuts the blind slots of the target layer separated from the multilayer circuit board. In this area, the target layer cannot form a connection with the material covered above it.
Uv laser processing applications in PCB industry
Each circuit layer in the multilayer circuit board is pressed together by the action of semi-cured sheet; Depending on the circuit design, some areas of the semi-cured sheet need to be cut and then pressed together.
Characteristic impedance of a transmission line
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.
Controlled impedance circuit board design and interconnector characteristic impedance
Even many electronic design engineers are confused. This material will provide a brief and intuitive introduction to characteristic impedance, hoping to help you understand the rather basic qualities of transmission lines.
How to avoid PCB Electromagnetic Interference in Switching Power Supply Design
Take the core component of each functional circuit as the center, and carry out the layout around it. The components should be arranged evenly, neatly and compact on the PCB, and the leads and connections between the components should be reduced and short
Replacement of IC chips of the same model
Internal equivalent PCB circuit and application PCB circuit some of the lead out feet are not marked, encounter empty lead feet, should not be grounded without permission,
High reliability PCB's 14 important characteristics
All of these problems can cause the solder shield to detach from the circuit board and eventually lead to corrosion of the copper circuit. Poor insulation characteristics can cause short circuits due to unexpected electrical connectivity/arcing.
