Electroplated Hole Sealing/Filling On Ceramic PCB
Electroplated hole sealing is a common printed circuit board manufacturing process used to fill and seal through holes (through-holes) to enhance electrical conductivity and protection. In the printed circuit board manufacturing process, a pass-through hole is a channel used to connect different ...Read more -
Why should PCB boards do impedance?
PCB impedance refers to the parameters of resistance and reactance, which plays anobstruction role in alternating current. In pcb circuit board production, impedance treatment is essential. So do you know why PCB circuit boards need to do impedance? 1, PCB circuit board bottom to consider the ins...Read more -
poor tin
PCB design and production process has as many as 20 processes, poor tin on the circuit board may lead to such as line sandhole, wire collapse, line dog teeth, open circuit, line sand hole line; Pore copper thin serious hole without copper; If the hole copper thin is serious, the hole copper witho...Read more -
Key points for grounding booster DC/DC PCB
Often hear “grounding is very important”, “need to strengthen the grounding design” and so on. In fact, in the PCB layout of booster DC/DC converters, grounding design without sufficient consideration and deviation from the basic rules is the root cause of the problem. Be ...Read more -
Causes of poor plating on circuit boards
1. Pinhole The pinhole is due to the adsorption of hydrogen gas on the surface of the plated parts, which will not be released for a long time. The plating solution cannot wet the surface of the plated parts, so that the electrolytic plating layer cannot be electrolytically analyzed. As the thick...Read more -
How to select suitable PCB surface to get longer service life?
Circuit materials rely on high-quality conductors and dielectric materials to connect modern complex components to each other for optimal performance. However, as conductors, these PCB copper conductors, whether DC or mm Wave PCB boards, need anti-aging and oxidation protection. This protection c...Read more -
Introduction to reliability testing of PCB circuit boards
The PCB circuit board can combine many electronic components together, which can save space very well and will not hinder the operation of the circuit. There are many processes in the design of the PCB circuit board. First, we need to set Check the parameters of the PCB circuit board. Second, we ...Read more -
What points should be paid attention to in DC-DC PCB design?
Compared with LDO, the circuit of DC-DC is much more complex and noisy, and the layout and layout requirements are higher. The quality of layout directly affects the performance of DC-DC, so it is very important to understand the layout of DC-DC 1. Bad layout ●EMI, DC-DC SW pin will have higher d...Read more -
Development Trend of Rigid-Flexible PCB Manufacturing Technology
Due to different types of substrates, the manufacturing process of rigid-flex PCB is different. The main processes that determine its performance are thin wire technology and microporous technology. With the requirements of miniaturization, multi-function and centralized assembly of electronic pr...Read more -
The difference of PTH NPTH in PCB through holes
It can be observed that there are many large and small holes in the circuit board, and it can be found that there are many dense holes, and each hole is designed for its purpose. These holes can basically be divided into PTH (Plating Through Hole) and NPTH (Non Plating Through Hole) plating throu...Read more -
PCB Silkscreen
PCB silk screen printing is an important process in the production of PCB circuit boards, which determines the quality of the finished PCB board. PCB circuit board design is very complicated. There are many small details in the design process. If it is not handled properly, it will affect the per...Read more -
Cause of PCB falling solder plate
PCB circuit board in the production process, often encounter some process defects, such as PCB circuit board copper wire off bad (is also often said to throw copper), affect product quality. The common reasons for PCB circuit board throwing copper are as follows: PCB circuit board process facto...Read more
