Layered with heat-curing resin, the laser drilled copper plated copper to form vias and circuit patterns. At present, the international HDI laminated materials with epoxy resin with different curing agent to add inorganic powder to improve material rigidity and reduce CTE, but also the use of glass cloth to enhance rigidity. Future trends. The carrier board will continue at fine BGA and CSP spacing, while coreless boards are more commonly used with carrier boards of four or more layers, the roadmap shows smaller feature sizes of carrier boards, lower performance requirements for critical dielectrics, lower dielectric Thermal expansion coefficient and high heat resistance, the pursuit of low-cost substrate to meet the performance goals.

Keyword: Low Cost PCB || Custom PCB || Quick turn PCB || Matel PCB || High TG PCB Industrial applications High-power industrial applications for PCBs are also commonplace. These electronic components control the mechanisms used in factories and manufacturing facilities and must withstand the harsh conditions often seen in industrial equipment. This can include anything, including harsh chemicals, vibrating machinery and rough handling. Industry standards are equally stringent in such a fast-paced, challenging environment. Currently, thick copper PCBs are often seen in other applications (much larger than a standard ounce PCB). This PCB facilitates high current industrial applications and battery chargers. Industrial Equipment: Many electric drills and presses used in manufacturing use PCB control electronics. Measuring Equipment: PCB operation commonly used in equipment used to measure and control pressure, temperature and other variables in industrial manufacturing. Power Equipment: DC-AC power inverters, solar cogeneration equipment and other power control equipment usually track and control the current through the PCB.

Keyword: SMD Stencil || PCB Metal Core || PCB Fabrication || PCB SMT || Laser PCB What is a technical pcb? While technology tracks are not the actual components that make up a printed circuit board (PCB), they are important for PCBs assembled by Surface Mount Technology (SMT). As its name suggests, the technology track functions as a pcb. Conveyors are used during SMT assembly to transfer PCBs for solder paste printing, pick-and-place, reflow / wave soldering and inspection. Circuit boards will never be able to transmit safely and effectively unless they snap onto the conveyor accurately through technology tracks. Figure 1 below shows the structure of the technology track. Why do I need technical pcb? The main responsibility of the technical pcb lies in its role as a "helper", even though the manufacturability of the assembly is well underway. This stems from the need for the SMT placement machine to secure the side of the circuit board and transfer the circuit board to the reflow oven. Therefore, if the components are designed too close to the edge of the board, the components may be "attacked" when picked and placed or soldered, resulting in errors or even failure. In addition to SMT assembly, this also applies to through-hole assembly and wave soldering.

Examples of situations where thicker copper PCBs would be beneficial include motor controllers, high current battery chargers, and industrial load testers. Light. As their LED-based lighting solutions are popular for their low power consumption and high efficiency, the same is true for the aluminum-backed PCBs used to make them. These PCBs serve as heat sinks and allow higher levels of heat transfer than standard PCBs. These same aluminum backplanes form the basis for high-lumen LED applications and basic lighting solutions. Automotive and aerospace industries. Both the automotive and aerospace industries use flexible PCBs designed to withstand the high vibration environment common in both areas. They can also be very lightweight, depending on the size and design, which is necessary when manufacturing parts for the transportation industry. They are also able to meet the tight spaces that may exist in these applications, such as the inside of a dashboard or the dashboard.

Keyword: PCB Resin Solution || PCB Copper || PCB Electrical || PCB Stencil The resin solution is actually a mixture of epoxy, curing agent and catalyst, combined with an organic solution, for impregnating the glass fiber cloth. The glass fiber cloth is dried at a temperature of 120 ° C to 170 ° C for 2 to 15 minutes after being impregnated into a prepreg having a plurality of voids with a thickness of 0.04 mm to 0.3 mm. The resin content of the prepreg is usually 30% or more. Resin film has high thermal conductivity This is a resin film with an inorganic filler added to a thermosetting, highly thermally conductive inorganic filler. The application resin is actually a prepreg resin and curing agent system with multiple voids. Inorganic fillers come in many categories and sizes. For example, alumina (Al 2 O 3) powder, aluminum nitride (AlN) powder, silicon dioxide (SiO 2) powder, silicon nitride (SiN) powder, and boron nitride (BN) powder may be used to conduct high thermal conductivity And, it is possible to apply organic fillers with excellent insulation properties. Alumina (Al 2 O 3) powders are well suited for this application, and if an oxidation treatment is used, an oxide film can be formed on the surface of the powder particles, which is advantageous for improving the moisture resistance product.

Keyword: Thick Copper PCB || PCB Copper Cutting || PCB Solderin || PCB Etching In this study, a square needle profile tool was used to friction stir weld a 10 mm thick, pure copper plate at a constant rotation speed of 700 rpm and different lateral speeds of 50, 100, 150 and 200 mm / min. Thermal cycles and peak temperatures are recorded using a precision thermocouple. In addition, microstructural features of the joint were examined by light microscopy. In addition, in order to analyze the mechanical properties of the joint, hardness and tensile tests were performed. In addition, the joint was dissected using a scanning electron microscope. The results show that higher traversing speeds lead to lower heat input and peak temperature, resulting in finer particles. In addition, higher traversing speeds lead to the formation of defects in the joint. As the traversing speed increases, the ultimate tensile strength of the joint increases to a maximum and then decreases. Similarly, as the traversing speed increases, the joint stiffness and elongation increase and decrease, respectively. In addition, joints welded at lower traversing speeds show more ductile fracture modes.

Keyword: PCB Prototype || Heavy Copper PCB || High-Tg PCB || Custom PCB || HDI PCB PCBs are very durable in soil and water, with no known decomposition processes other than the slow degradation of microorganisms. They stick to the soil or evaporate, so they are usually not submerged in the groundwater. PCB contaminated deposits in lakes or rivers can slowly release the PCB back into the water and eventually evaporate. In water, a small amount of PCB may still dissolve, but most adhere to organic particles and bottom deposits. PCBs are absorbed in water by small organisms and fish. They are also consumed as food by other animals that eat these aquatic animals. PCBs accumulate in fish and marine mammals, reaching levels that can be thousands of times higher. Farmed salmon contain higher levels of PCBs than wild salmon. This reflects the fact that farmed salmon may be submerged in small fish contaminated by contaminated marine waters. The short-term health effects of short-term exposure to MCL are acne-like eruptions and skin pigmentation; auditory and visual problems; spasms. Long-term health effects Exposure to a lifetime above MCL levels includes exposures similar to acute poisoning, irritation of the nose, changes in the throat and gastrointestinal tract, changes in liver function, and cancer.

Keyword: PCB Substrate || PCB Fabrication || PCB Assembly || PCB Material || PCB Electronics How to make PCB substrate with high thermal conductivity Thermal performance has been a major concern for PCB design and manufacturing engineers as well as PCB substrate materials with high thermal conductivity, playing an important role in improving the thermal performance of PCBs. Based on this basic principle, this article mainly introduces the manufacturing method of PCB substrate material with high thermal conductivity. Experiments show that the adiabatic performance is reliable, and the thermal conductivity reaches more than 3w / m · k. The main idea of this method This method of manufacturing a PCB substrate material with high thermal conductivity relies on the alternate stacking of prepregs with multiple voids prior to copper foil coating and resin films with high thermal conductivity. During heating of the stack, voids in the prepreg are filled with a resin composite material having a high thermal conductivity to become strong to obtain a PCB substrate material having excellent thermal and dielectric properties and a high thermal conductivity while maintaining the mechanical strength of the substrate .

Keyword: PCB Copper || Thick Copper PCB || Aluminum PCB || Low Cost PCB || PCB Electronics Copper in the PCB production process, has a very important position, sometimes the success or failure of copper, related to the quality of the entire board. The so-called copper, copper is filled into the solid substrate of the PCB free space. Copper has a large area of copper and grid copper two ways, a large area of copper increased current and shielding, but if the wave soldering, the board may tilt, or even blistering. Grid copper can reduce the heating surface of copper, but also play a role of electromagnetic shielding. However, the grid is composed of traces. If the width of traces is not correct, interference signals will be generated. Copper has many benefits for the PCB, such as improving the anti-noise ability, reduce the potential difference, reduce the ground impedance, improve anti-interference ability, reduce voltage drop, improve power efficiency, connected with the ground, reducing the loop area, cooling , Reduce the impedance. Since there are so many advantages of copper, in the operation, what should pay attention to it? 1, if the PCB to more, there are SGND, AGND, GND, it is necessary to the most important "ground" as a reference to independent copper. 2, the circuit in the crystal as a high-frequency source, near the copper, around the crystal, and then the crystal case separately ground. 3, do not appear sharp, that is, more than 180 ° angle, otherwise it will form a transmitting antenna.

Keyword: PCB Material || HDI PCB || Low Cost PCB || PCB Prototype || PCB Electronics In the automotive circuit board, the traditional single-layer PCB, double-layer PCB and multi-layer PCB available, in recent years, the widespread use of HDI PCB automotive electronics products of choice. The essential difference between an ordinary HDI PCB and an automotive HDI PCB is that the former emphasizes practicality and versatility to serve consumer electronics while the latter is committed to reliability, security and high quality. It is important to note that the rules and measures discussed in this paper are only some of the rules that are widely used, and do not include those special circumstances, since the vehicle covers a wide range of vehicle categories, such as cars, trucks or trucks, requiring different requirements for different performance expectations and functions The Automotive HDI PCB Classification and Application HDI PCB can be divided into three categories: single-layer HDI PCB, double-layer PCB and three layers to establish PCB. Here, the layer refers to the prepreg layer. Automotive electronics are usually used in the following two categories. One is an automotive electronic control device until they work with mechanical systems on vehicles such as engines, chassis and vehicle control, in particular electronic fuel injection systems, anti-lock braking systems (ABS), anti-skid control (ASC), traction Control, electronic control suspension (ECS), electronic automatic transmission (EAT) and electric power steering (EPS). The other is a vehicle-mounted vehicle that can be used independently in the automotive environment and has nothing to do with automotive performance, including automotive information systems or automotive computers, GPS systems, car audio and video systems, automotive communication systems and the Internet. A large number of controls are implemented by HDI PCB supported devices.

Keyword: Thick Copper PCB || PCB Maker || PCB Prototype || PCB Fabrication || PCB Material In all these tests, we have a lot of empirical evidence that slow response materials (such as cast iron and stainless steel) have hot spots that can produce significant uneven heating and scorch in many common cooking conditions. But, obviously, people who like some kind of material (especially cast iron) still like them and want to use it for a variety of reasons. What about those copper stove diffusion plates? Most of what I can find is 1/8 "thick copper plate - at least as thick as 2.5-3.0 mm copper, we see recommended for good copper cookware, so they should be able to distribute heat on the surface of the board as copper cookware The Obviously, you can get a piece of copper from the sheet metal source cut into specifications. Does anyone have the experience of using a copper plate to mediate the uneven burner and the uneven pot? How does it work for you? In theory - assuming we have a pan, most of the pan with the copper surface of the diffuser plate, can we convert the cast iron (or stainless steel) pot into a relatively uniform heating surface? Obviously, we will lose some reaction, because the heat must be spread through a lot of metal - but the iron is not good reactivity, then this will be worse? We lose some efficiency - need extra heat to raise the temperature of the copper and radiate from the exposed surface around the pot. But the use of cooking energy for cooking energy is often quite insignificant (it is quite bad in terms of thermal efficiency).

Often a friend joked that Beijing people fight right, Shanghai people fight money, and Shenzhen is hard, so it was able to achieve "Shenzhen speed" reputation! In addition to this, in addition to years of industrial subdivision of the scale produced by the effect, in fact, there are endless bitterness ... ... Circuit board factory from the late 80s of last century to the present after 20 years of rapid development, experienced a state-owned economy, Sino-foreign joint ventures and foreign-owned enterprises as the mainstream of the three stages of development, has made remarkable achievements. China PCB industry in the world worthy of the dominant position. With the world's investment in China's IT industry, the rapid development of electronic machine manufacturing, the world's circuit mills have also been large-scale investment in China, China's PCB factory manufacturing industry has become a world-class scale, production, output value has been Ranking the forefront of the world. Especially in the middle and low price on the PCB has a strong competitive edge, with the machine to the high performance, miniaturization direction, the development of its difficult circuit board factory is also increasing, but the size of the factory continues to increase, circuit board industry The price of vicious competition is also repeated. First, R & D and production technology is relatively backward. With the rapid development of electronic technology and the market demand for "short, small, light, thin" electronic products continue to expand, requiring the circuit board product technology must be rapidly improved, high multi-layer, fine line pores, fast transfer PCB demand Increasing. This for each manufacturer, means that there must be a large capital investment, to step by step to enhance the technical staff and the overall technical strength of enterprises in order to be met, the investment of heavy assets will be a major difficulty. In the face of these challenges, in addition to the circuit board manufacturers actively carry out the talent pool, strengthen the personnel training and training work, I hope the government can cultivate and build their own world-class enterprise point of view, give enterprises a certain policy support and support; The government should invest funds to establish research institutions or cooperate with representative enterprises to carry out PCB frontier technology research, for domestic enterprises to provide new technology services and support. Second, the circuit board industry confusion, vicious competition. At present, the industry in the production and management of general products, there is uneven development, investment irrational, rapid expansion and the emergence of serious vicious competition, profit levels, profitability is poor, which will seriously affect the health of the industry development of. Many large enterprises rely on export tax rebates, selling scrap to profit; even lower than the cost of price to win market orders, to expand sales output to financing the market, and strive to profit in the stock market ... ... Based on this, it is recommended that the circuit board manufacturers from their own The actual situation, by actively promoting self-technical ability or make full use of and play their own advantages to the characteristics of business to create their own core competitiveness, to avoid low-level vicious competition. Again, the strict requirements of environmental protection is China's PCB industry is facing a major challenge, is bound to strict supervision, which of course is a good thing. However, if the relevant departments of this industry to do a lot of understanding and support, so that the circuit board industry has a reasonable profit, I believe that the industry practitioners will naturally not let a drop of heavy metal waste water discharge, after all, people are conscience. China's circuit board factory enterprises, mostly small and medium enterprises, they are in the lead-free technology to master and enhance the failure to keep up with the needs of users. In the face of a wide range of lead-free technology, the difference between the needs of users of the situation, each manufacturer needs a variety of investment, resulting in increased investment costs and technical adaptation, technical management increased the difficulty. This problem can only be achieved through a more detailed division of labor and cooperation in order to enable industry companies to better and more effectively eliminate this effect. Finally, the rise in raw material prices and the fall in prices of downstream electronics severely squeezed the profits of the PCB industry in the middle. In the face of severe living space, enterprises should increase the investment in technology, R & D, master the core technology of PCB production, control the cost to improve the maximum pass rate, and change the simple profit model, if you do not worry about production costs, and rely on tax rebates, Or the so-called other improper financial means to win the benefits, it will be the tragedy of this industry.
