Positioning holes on printed circuit boards should be represented by special graphic symbols. When the requirements are not high, the printed circuit board can also be used in the larger assembly hole instead.
There are several parameters to consider when designing PCBS for high frequency applications. This article discusses these factors, as well as the application of high frequency printed circuit boards.
The manufacturing process of printed board is still more complex, to go through the light painting, photographic plate and other chemical processes, consume more materials, longer cycle, high cost.
it is worth familiarizing yourself with the preferred material for a particular number of layers and making every effort to design a PCB to match it. There will always be exceptions to specific design requirements, but in general, standard materials are t
This is because the pad will likely be rectangular, which means that the average PCB assembler will consider applying the paste in this shape as optimal.
A protective coating is a polymer film applied to the PCB surface to protect the PCB board and its components from corrosion and environmental contamination.
The temperature resistance test of PCB circuit boards is to prevent adverse reactions such as board bursting, foaming and delamination at excessively high temperature, leading to poor product quality or direct scrap, which is a problem that needs to be pa
In the end, the manufacturer will have to discard the defective board or accept costly and time-consuming repairs that may not have a clear answer to the root cause of the defect.
When adopting this method, it is necessary to ensure that the width of the bridge between the two ground is equal to the width of the IC, and that no signal line can cross the division gap.
Purpose and function: to remove the oxide on the copper surface of the line, the ink residue film remaining glue, to ensure a binding force between copper and graphic plating copper or nickel
Organic pollution of gold cylinder using carbon core continuous filtration, and add appropriate amount of gold-plated additives.
Modern wireless applications require sturdy antennas, which often means a long printed circuit board to integrate and support these applications. Antenna designs can make or break your application, but relying on long PCBS can help you get the job done ri
