       SMT is a mounting technology that does not require drilling insertion holes on the PCBA board, but directly attaches or solders surface mount components to the component positions specified on the surface of the PCBA board. So what are the advantages of SMT processing?       1.  M iniaturization SMT processing has the characteristics of high assembly density, small size and light weight. The volume and weight of SM T   components are only about 1/10 of those of traditional plug-in components.  Generally, electronic products  are   reduced by 40%~60%   in volume   and 60%~80%   in weight after using SMT .   The distance between the adjacent electrodes of the SMT component s  is much smaller than the lead spacing of the traditional DIP integrated circuit, and the current pin spacing has reached 0.3mm.     2. Electrical  P roperties Surface mount components reduce parasitic lead and conductor inductance while improving the characteristics of capacitors, resistors and other componen

      Farewelled to 2021 and welcomed 2022, HoYoGo welcomed its employees ’ s November-December birthday party! At the beginning of the birthday party, the birthday stars  employees  received the birthday cake prepared by the company. Along with the birthday song, the birthday stars blew out the birthday candles with the blessing of the HoYoGo people, cut the birthday cake together, and shared the joy of birthday!       Then, Yumi spoke: At work, we showed our trust and our value in our position. If a job is worth doing, it is worth doing well. She also said that our turnover  in 2021  was better than  in 2020 , and we doubled our performance in many months  in 2021 . This is because we value "reply in time" as our work criterion, because when  time  is passed, the opportunit ies   are  missed, and the  timing  and the good opportunit ies  coexist, so it is very important to reply in time!       Mr. Liu Spoke ： That day was the last day of 2021, no matter what our 2021 was, a

  In the PCB industry, manufacturers have many methods for PCB inspection. For example: signal injection method, substitution method, offline Inspection, online inspection, parameter test method, waveform observation method, visual inspection method, signal tracking method, AC short circuit method, separation test method, etc. The intelligent detection method of the circuit board needs to select the online test method according to the specific characteristics of the PCB board, in order to combine one or more processes, complement each other, and make comprehensive utilization. First, use the idea of virtual instruments on the PCB to establish related application software, that is, implement various functions of traditional instruments through software, including oscilloscopes, signal generators, and various mathematical processes on the collected data. During the test, the digital signal is given by the test software. Then, the PCB test system will have new design ideas. Adopt the desi

  Electronic equipment needs high performance, high speed, thin, light and short, and PCB is a multidisciplinary industry and the most critical technology for high-end electronic equipment. The rigidity, flexibility, rigidity-flexibility of multi-layer boards in PCB products, as well as the module substrates used for IC packaging substrates, have made great contributions to high-end electronic equipment.     From the current PCB technology, we can see the following five development trends: First:  Development along the path of high-density interconnect technology (HDI) Since HDI embodies the most advanced technology of contemporary PCBs, it can bring thin lines and small apertures to PCBs. Among HDI multilayer board application terminal electronic products, mobile phone is the model of HDI frontier development technology. In the fine wires of the PCB motherboard in mobile phones, the wire width/spacing has become mainstream. In addition, the thickness of the conductive layer and the bo

  When testing the PCB, you need to pay attention to some details. And in order to ensure the best product quality, please pay more attention to the following 9 common sense.   1. It is strictly forbidden to use the grounded test equipment to contact the TV, audio, video and other equipment on the baseboard to detect the PCB without the isolation transformer.   Although the general tape recorder has a power transformer, when it comes to a special TV, or especially a TV or audio equipment with a large output power or a poor understanding of the nature of the power supply used, it is first necessary to find out whether the chassis of the machine is charged or not. Otherwise, it will be very easy to short-circuit the power supply to the equipment with the baseboard, and the IC will be further affected.     2. When testing the PCB, please pay attention to the insulation properties of the soldering iron.        It is not allowed to use soldering iron for welding. If you need to confirm that
