1. PCB stack method is recommended as Foil superposition method2. Minimize the use of PP and CORE models and types in the same stack (no more than 3 PP layers per layer).3. The thickness of PP medium between 3 and two layers should not exceed 21MIL. (thick PP dielectric processing is difficult. Generally, a core panel will be added, resulting in the increase of actual laminated number, which will increase additional processing cost).4. PCB outer layer (Top, Bottom layer) generally select 0.5OZ t...

Introduction:The components are developing towards high speed, low consumption, small volume and high anti-interference. PCB design is an important stage of electronic product design. It can realize the connection and function between electronic components, and is also an important part of power circuit design. High frequency circuit has the higher integration and the higher layout density, so it is very vital how to make layout more reasonable and more scientific.PCB can realize the connection ...

Signal Integrity Analysis for High-speed PCBIntroduction:As large-scale and ultra-large-scale integrated circuits are more and more applied to power circuit systems, the requirements of users are higher and higher. As a result, the integration scale of chips is larger and smaller, the number of pins is larger and higher, and the frequency is higher and higher. However, the rapid development of the circuit brings about such a problem: the chip size is getting smaller, and the pins are generally i...
View MoreBackground:After the production of PCB, the original components need to be assembled to be used further. At present, the most common assembly methods are wave soldering, reflow soldering and the combination of the two technologies. The quality of PCB has great influence on the assembly quality of the three processes.Wave Soldering:Technological introduction: Wave soldering is a bulk soldering process used in the manufacture of printed circuit boards. The circuit board is passed over a pan of mol...

Introduction:PCB panel is a combination of several PCB unit boards with various possible connection modes, as shown in the figures below.Typical, when a hardware designer a PCB, he considers the electrical signal and the layout of the components on the circuit board, focusing on the function of the product. Less consideration is given to PCB manufacturing and assembly. To make PCB production smooth, especially for SMT assembly, special attention should be paid to PCB assembly design.I. Pur...

Introduction:As a kind of traditional welding technology, wave soldering and reflow soldering play an active role in the field of electronic manufacturing in the assembling process of electronic products. The quality of welding is related to product performance, reliability, service life, etc., and will affect each subsequent process flow. By analyzing and comparing the defects in the process of wave soldering and reflow welding from the quality control before welding, production process materia...

Background:In the information age, the update speed of electronic products is accelerated. In one hand, the popularity of computers, mobile devices, portable devices and other products has made people's demands on electronic products higher and higher, which means that the performance of products must be improved in order to meet people’s requirements. The feature size of IC chip should be smaller and smaller, and the complexity should be increased. That is to say, the number of I/O in the c...

At the same time, PCB is also developing towards high precision, high speed, high density and so on. In particular, the rapid development of SMT makes the hot air leveling process increasingly unsuited to the requirements of PCB manufacturing process. Meanwhile, the welding material, such as Sn-Pb, used in the hot air leveling proce...

But it's the small, trivial issues that ultimately get in our way. This article is aimed at PCB board design, production and some problems encountered in maintenance, such as the voltage resistance of diode, electromagnetic interference, the shedding of welding pads and the replacement of vulnerable parts, etc. Under the principle of minimizing ...

Introduction:The substrates used in PCB are mainly divided into two categories: organic substrates and inorganic substrates. Among them, the organic substrates are made of several types of materials which refer to the reinforcing materials, such as glass fiber cloth, fiber paper, glass felt, etc. These reinforcing materials are impregnated with resin adhesive and dried, then covered with copper foil at high temperature and high pressure. This type of substrate, known as copper clad laminate (CCL...

Background:At present, the environmental problems involved in PCB production are particularly prominent. Lead and bromine are the hottest topics at the moment; Lead-free and halogen-free will affect the development of PCB in many ways. Although changes in the surface treatment process of PCB are not significant at present and seem to be relatively distant, it should be noted that the slow change in the long term will lead to great changes. PCB surface treatment technology is bound to change dram...

Introduction:Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). In industry, it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. Both technologies can be used on the same board, with the through-hole technolo...

What Do You Know About HDI—by PCBWayBasic Information:HDI board refers to High Density Interconnect, namely High Density Interconnect board. It is a relatively new technology developed by PCB industry in the end of 20th century. When the drilling hole size of the traditional PCB reaches 0.15mm, the cost is very high and it is difficult to improve it again because of the affection by the drilling tool. The drilling of HDI board no longer relies on traditional mechanical drilling, but uses the las...
