Therefore, pcb manufacturers believe that when designing or reinforcing equipment, they should be placed on PCB boards with higher hardness, or use certain methods to avoid pcba processing.
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.
Both schematic drawing and PCB design should be considered from the high frequency working environment in order to design a more ideal PCB.
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,
The manufacturing process of PCBA involves many links, and only by controlling the quality of each link can a good product be produced. Generally, PCBA is made of a series of PCB circuit board manufacturing, component purchasing and inspection, SMT patch
PCB fabrication, of course, refers to the fabrication of the bare printed circuit board itself, while PCB assembly refers to placing components on the printed circuit board.
On the printed circuit board, the electrical connection of all components is carried out through the pad. Pad is the most important basic unit in PCB design.
The general PCB basic design process is as follows:Preliminary preparation →PCB structure design → mesh guide → rule setting →PCB layout → Wiring → Routing optimization and silk screen → Network and DRC inspection and structure inspection → light drawing
Double-sided PCB extends from the substrate surface to both sides are composed of line layer, solder resistance layer, character layer, and through the drilling layer through the top bottom line to achieve connected electrical ventilation. In the actual p
Design used to pay attention to the visual effects of the board, now is different. The automatic circuit board design is not as beautiful as the manual design, but the electronic characteristics can meet the requirements, and the complete performance of t
