In general, the direction of wave soldering on the printed circuit board should be parallel to the long side of the printed circuit board and perpendicular to the short side of the printed circuit board.
The two long edges of PCB should be parallel, and the non-parallel edges should be added to facilitate the equipment transmission in the production and processing process.
Now the installation is mechanized, the hole position of the circuit board and the deformation error of the circuit and the design should be within the allowable range.
Experienced power developers know that EMI suppression in the PCB design process can save a lot of time for EMI suppression design in the final process to the greatest extent. This article will explain to you the specification steps in PCB EMI design, int
Wiring is the most important process in PCB design. This will directly affect the performance of PCB board. In the process of PCB design, wiring generally has such three levels of division: the first is the cloth, the most basic requirements of PCB design
G Handle the ground wire on the printed circuit board, the power cord and ground wire are the most important. To overcome electromagnetic interference, the most important means is grounding.
Attention should be paid to the wiring of signal lines under magnetic beads, between pads and those that may come into contact with magnetic beads. Some magnetic beads conduct electricity quite well and may produce unexpected conductive paths.
All kinds of reliability design in digital circuit application is related to the reliability requirements of the circuit in practical application and product engineering requirements, so it is not possible to add various kinds of high-cost "guarantee...
Many companies have started to set up a circuit board pricing program on their Web sites, with rules that allow customers to freely calculate prices. People who do not understand PCB can also easily calculate the price of PCB.
For the new PCB board we just got back, we should first observe roughly whether there are any problems on the board, such as whether there are obvious cracks, short circuit, open circuit and other phenomena.
The above is the overview of optical module PCB and optical device simulation. There are not many things to simulate, but there are also many places to be carefully handled.
Electrolysis of copper foil is also used in situations where the carrying capacity of the current can be increased by increasing the weight of copper to achieve a copper width, such as planar inductors.
