:This article describes the steps of checking the PCB Design placement in details.

:Nowadays, the pollution from PCB fabrication has aroused great public attention. The environmental pollution of PCB fabrication is mainly in the forms of waste water, exhaust gas, waste residue and so on.

:Nowadays, the increasingly sophisticated small PCB boards make the production more and more complex and bring about a lot of wastewater full of chemical substances in the processing.

:In high-speed multilayer circuit, growing data rate make signal integrity become a critical design issue which greatly affect the overall performance of a high-speed circuit.

:This manual is written by Gold Phoenix, it give very useful information in PCB copy processing.

:PCB layout is divided into right-angled layout, differential layout and S-shaped layout.

:PCB reverse engineering is to obtain the PCB circuit design, circuit schematics and BOM of an excellent electronic product.

:After struggling for nearly half a century, China PCB has become an indispensable part in the Chinese electronic information industry .

:Rigid-flex pcb is a kind of pcb that is composed of several rigid areas and several flexible areas which is widely used in different fields, such as mobile phones, consumer electronics and automotive.

:Flexible PCB is made of flexible insulating substrate with high wiring density, light weight and small thickness.

:HDI PCB is defined as a PCB with a higher wiring density per unit area than conventional PCB and is used to reduce size and weight, as well as to enhance electrical performance of the device.

:

:At present, multilayer pcb has been widely used in various electronic devices and it has become an important part among the electronic components owing to its mumerous advantages。

:Gold Phoenix PCB make it easy for a company to locate an outside organization to provide the PCBs, or printed circuit boards, that they need for electronic device production.

:Whatever our requirements for electronics manufacturing like PCB assembly and testing, we never seem to find the right PCB manufacturer to do that job for us.
