Teach you to control EMI radiation by PCB stacking

it is generally sufficient to handle high end harmonics and keep the transient signal low enough, that is, common-mode EMI can be dropped very low. The PCB layer-stack design example presented in this paper will assume layer spacing of 3 to 6mil.

Detail PCB board ESD

One end of the triangle is connected to a signal wire and the other is connected to ground. When static electricity is present, a tip discharge is generated which consumes electrical energy.

5G mobile phone era is coming, PCB has new living water?

5G phones will also bring new opportunities to the printed circuit board market, as Chinese mobile phone giants ZTE and Huawei announced in August that the first 5G phones will be officially sold.

Five key points of PCB circuit board design!

Now PCB design time is shorter and shorter, smaller and smaller board space, higher and higher device density, extremely demanding layout rules and large size components make designers

The circuit is also the road to understand the PCB wiring

When you don't have a concept of PCB design, just think about our daily road, the two are exactly the same.

Analysis of layout and routing methods for mixed signal PCB design

The special requirements for power transmission lines and the need to isolate noise coupling between analog and digital circuits add further complexity to the layout and wiring of mixed-signal PCBS.

Methods to prevent the warping of PCB printed boards

The board on which the components are installed is bent after welding, and it is difficult to cut the feet of the components neatly. The board can not be installed into the chassis or machine socket, so the assembly plant encountered the board is also ver

How to measure the dielectric constant of PCB circuit board material at millimeter wave frequency?

While raw material test methods often introduce uncertainties related to test fixtures or test devices, circuit test methods include uncertainties from test circuit design and fabrication techniques. Because the two methods are different, measurement resu

The advantage of pcba to contract labor and materials

1. PCBA processing refers to PCB bare board after SMT patch, DIP plug-in welding, post-welding, cleaning, three anti-paint spraying, testing aging, etc.; After the whole processing process to form PCBA, referred to as PCBA processing2.SMT patch processing

How to choose PCBA manufacturer

1, PCBA processing equipment, 2, PCBA processing plant environment, 3, PCBA processing technical service ability, 4, PCBA processing finished product packaging, 5, assess the overall strength of PCBA processing plant, 6, PCBA processing price and delivery

Reasons and solutions for PCBA welding spot pulling

PCBA processing and welding process is mainly divided into three parts: one is SMT reflow welding, two is DIP wave welding, three is manual soldering iron welding

PCB circuit board design and wiring principles

How to improve SMT SMT processing efficiency: first, advance work preparation, second, ensure the SMT SMT machine running time balance, third, equipment operating parameters
