Here you'll find insights into PCB design, tech trends, assembly issues, and trending topics
in the general news media as they relate to printed circuit board technology.
As experts in the manufacture and assembly of printed circuit boards, we work to make our blog a helpful resource on PCB topics and the industries that we work with, including automotive, consumer electronics, aerospace and many more.
This is the second version of a device I designed to alert me in the unfortunate event the nozzle clogs. It communicates with the printer!
If your PCB layout has through-hole elements that will certainly be wave firm after that a tented by means of will certainly avoid the solder from moving up right into the using and also over the opposite of the PCB where it can possibly short out parts. Vias that are likewise near to SMT pads need to additionally be tented.
When designing the PCB board, the most consideration for our wiring is how to connect each layer to the network signal line in the most reasonable way. The denser the high-speed PCB board circuit, the greater the density of vias (VIA) is placed, and the vias can serve each layer. The role of electrical connection between.
At first glance, PCB is almost the same regardless of its internal quality. It isthrough the surface that we see differences, which are critical to the durability and function of the PCB throughout the lifespan.
In the field of network communication, in ATM switches, core routers, Gigabit Ethernet, and various gateway devices, the system data rate and clock rate continue to increase, and the operating frequency of the corresponding processor is also higher; data, voice, and image transmission.

In design, layout is an important part. The quality of the layout results will directly affect the effect of the wiring, so it can be considered that a reasonable layout is the first step in the success of PCB design.
Since the printed circuit board is not a general end product, the definition of the name is slightly confusing. For example, the motherboard for the personal computer is called the motherboard and cannot be directly called the circuit board. Although there is a circuit board in the motherboard, It's not the same, so when you evaluate the industry, you can't say the same thing. For example, because there are integrated circuit parts on the board, the news media called him an IC board, but in fact he is not equivalent to a printed circuit board.
Although the high-speed simulation tools and interconnect tools at this stage can help designers solve some of the problems, high-speed PCB design also requires the accumulation of experience and in-depth communication between the industry.
Can you introduce some foreign technical books and materials on high-speed PCB design?
The range of variations in characteristic impedance control must consider four factors:
The significance, classification and composition of electronic circuit diagram
To do a good design, as the designer's first thing to do is to have a general overall layout, in order to make a specific design. The same pcb design is also the case, want to make the pcb board to achieve what they want, the overall layout, the placement of components is the primary consideration, they play a key role in the design of pcb board, they directly affect the entire printed circuit Board installation, reliability, ventilation, heat dissipation, wiring through rate.
The schematic design software will be available in ORCAD. The supported Netlist is much more than the industry standard.
Today's computer system DDR3 memory technology has been widely used, and the data transmission rate has been repeatedly improved, and has now reached 1866Mbps. Under such high-speed bus conditions, to ensure the reliability of data transmission quality and meet the timing requirements of parallel buses, it poses great challenges to design implementation.
Multi-layer and double-sided PCB design is similar, and even easier.

The anti-jamming measures that are not common in some literatures are detailed below. Considering the practical application, especially in the trial production of products, double panels are still widely used. The following contents are mainly for double panels.

In the low-power RF PCB design, the standard FR4 material is used (good insulation properties, uniform material, dielectric constant ε = 4, 10%).
