Seven issues to consider when designing PCB printed circuit boards! For ease of expression, it is analyzed from seven aspects: cutting, drilling, wiring, solder mask, characters, surface treatment and forming.

Electroless copper plating is an autocatalytic redox reaction. Electroless copper plating has been widely used in our PCB manufacturing industry. At present, electroless copper plating is used for PCB hole metallization.

It is critical that PCBs have reliable performance, both in the manufacturing assembly process and in actual use. Fourteen important features of high-reliability PCB circuit boards.

The corresponding printed circuit boards also face the challenges of high precision, thinning and high density. The trend of printed boards in the global market is to introduce blind and buried vias in high-density interconnect products, so as to save space more effectively and make the line width and line spacing thinner and narrower.

The industry is very competitive these days, and everyone is looking for ways to integrate the most functionality with the smallest size and cost. Analog, digital, and RF circuits are all tightly packed together with very little space to separate their respective problem areas, and the number of board layers is often minimized due to cost considerations.

PCB multilayer board lamination process overview: pressure cooker, cap lamination, wrinkle, copper foil lamination, depression, kiss pressure, low pressure, kraft paper, lamination, large lamination.

PCB board sampling quality control method. Soldering is an important process step in the PCB proofing process. In order to ensure the soldering quality of the circuit board, you should be proficient in quality control methods and soldering skills.

What are the common problems encountered in the process of PCB circuit board proofing design? do you know? Let us introduce to you below!

Generally, a conductive pattern made of a printed circuit, a printed component or a combination of the two is called a printed circuit board on the insulating material according to the predetermined preset. The conductive pattern that supplies electrical connection between components on an insulating substrate is called a printed circuit. In this way, the printed circuit or the finished board of the printed circuit is called a printed circuit board, also known as a printed board or a printed circuit.

Commonly used PCB surface treatments are as follows: gold plating (gold plating, immersion gold), silver plating, OSP, tin spraying (lead and lead-free).

The conductive hole plugging process in PCB design, the conductive hole Via hole is also known as the via hole. In order to meet the customer's requirements, the via hole must be plugged. After a lot of practice, the traditional aluminum sheet plugging process is changed, and the board is completed with a white mesh. Surface solder mask and plug holes. Stable production and reliable quality.

There are many ways to solve the EMI problem. Modern EMI suppression methods include: using EMI suppression coating, selecting appropriate EMI suppression parts and EMI simulation design. This article starts with basic PCB layout and discusses the role and design techniques of PCB layer stacking in controlling EMI emissions.

PCB printed circuit board design output and parasitic capacitance of vias, parasitic inductance of vias and vias in high-speed PCB, related issues of drilling design costs.

What is the significance of PCB impedance for PCB circuit boards, and why do PCB circuit boards need impedance? This article first introduces what impedance and the type of impedance are, secondly introduces why the PCB circuit board needs to be impedance, and finally expounds the meaning of impedance to the PCB circuit board. Follow us to learn more about it.

In the whole production process, there are many control points, if a little carelessness, the board will be broken, and the quality problems of PCB circuit boards are endless, which is also a headache, because only one of them has problem, then most of the devices will also fail to use.

Do you know why the PCB must be baked before SMT can pass through the reflow oven after it expires and exceeds the shelf life? The main purpose of PCB baking is to dehumidify and dehumidify, and to remove the moisture contained in the PCB or absorbed from the outside world, because some materials used in the PCB itself are easy to form water molecules.
