  In PCBA processing, SMD components and DIP components are used.   So, what is the difference between SMD components and plug-in components?   l  The advantages of both   Advantages of SMD components   1. reduce the size of the product: SMD components are only about 1/10 of the volume of traditional cartridge components; general SMT processing, electronic products to reduce the volume of 40% to 60%.   2. improve production efficiency, reduce costs: SMT chip processing is easy to achieve automation, improve production efficiency, saving materials, energy, equipment, manpower, time, etc., reduce costs up to 30% ~ 50%. Easier to weld than plug-in components.   3. lightweight: the weight of SMD components is only 10% of the traditional plug-in components; general use of SMT after the weight of the product to reduce 60% ~ 80%.   4. high reliability, strong anti-vibration ability.   5. high-frequency characteristics, reduce electromagnetic and radio frequency interference. Because the SMD c

Nowadays, devices are becoming more and more compact in design, which means that the thermal power consumption per unit of volume becomes larger. But the biggest problem with electronic products is temperature. Most electronics get hot over time, and batteries become less durable the longer they are used.   High temperatures degrade the insulation properties of electronic products, components are gradually damaged and materials become aged. Generally speaking, high temperatures reduce resistance, which is why their lifespan becomes shorter. Other materials such as transformers in electronic products are affected by high temperatures and their performance decreases, mechanical strength decreases and electrode currents increase, causing temperatures to rise further and eventually rendering components ineffective.   LDO Chip Products   The LDO is a device that is used in many of our consumer electronics and other devices, so the analysis related to thermal calculations is done for this de

Semiconductors are the main components used in transistors, LED displays, solar cells, and perhaps more commonly used in microchips. As the demand for microchips in many industries continues to increase, manufacturers are struggling to keep up, and the current delivery time is very long. And the supply of semiconductors is limited. But what prevents manufacturers from meeting this requirement?     Fast-growing markets and new technologies   Although issues related to the pandemic have certainly exacerbated these problems, component shortages started long before quarantines and travel restrictions. Electronic equipment and vehicles require microchips, and therefore semiconductors.   These markets continue to grow exponentially, as many people buy new smartphones every time a new model comes on the market, more and more home devices are compatible with the Internet of Things, and the imminent ICE driving ban prompts consumers to switch to electric vehicles. With the rapid growth of thes

First of all, we must clarify the purpose of the schematic review: to identify problems in advance and improve the product design. Therefore, before the review, we have to list out the possible problems with the product design experience and make a targeted review. The process is pragmatic and the reviewers are multi-faceted in their assessment of the design. The schematic review mainly involves hardware engineers (and procurement engineers) and embedded software engineers.   ★ Drawing inspection： •A modular design is recommended for the schematic diagram, with a general diagram on the first page describing the relationship between the modules logically and clearly. •Each module is labeled with the relevant power consumption calculation, key elementary parameters are labeled, the power supply section indicates the input and output, and EMC test standards. •Clear logic between modules, smooth signal flow and easy to understand network signage.   ★ Component inspection • The selection of

  Pcb panelization refers to the process of putting together a small PCB directly from the manufacturer to make a whole block.   ★ Why do you need to panelize pcb, what are the benefits of doing so?   1. To meet the needs of production. Some PCB boards are too small to meet the requirements of making fixtures, so they need to be put together for production.   2. To improve the soldering efficiency of SMT placement. Only one SMT pass is required to complete the soldering of multiple PCB.   3. Improve cost utilisation. Some PCBs are shaped, and the patchwork can be a more efficient use of PCB area, reduce waste and improving the utilization of costs.   ★ How many ways are there to design a pcb panel?   1.V-CUT V-CUT is a slot drawn in the joint of two boards, as long as the two boards are put together, leaving a gap between them (usually 0.4mm), but the joint of the boards is thinner in this area and easy to break when putting together the boards you need to merge the edges of the two bo

PCB board industry partners know that the copper-lined board in the insulation material post a copper foil, and then baked dry. If you look carefully, you will see that there will be shrinkage in the drying process, the stress in all directions will be generated, which is the source of stress, followed by the purpose of PCB drilling before baking the board, in fact, the main moisture, PCB drilling before baking the board is to remove moisture from the board to reduce internal stress; pressed together behind the print resistance welding, including characters, etc. need to bake. Before shipping and packaging, there is also a process of baking the press board, also to remove moisture, after baking the board in terms of warpage has a relatively large improvement.   The baking mentioned above can eliminate the internal stress of the PCB board, which is to stabilize the size of the PCB. Its most significant advantage is that it can make the water in the pad dry after baking, strengthen the w
