Looking ahead, TAMURA's lead-free solder paste has been gradually replaced by leaded solder paste, and low silver solder paste has been developed to fill the automotive electronics gap; A variety of MALCOM SMT peripheral testing equipment is continuously
Therefore, for the first piece inspection, it is necessary to look at the following aspects: Measure and record all properties of the board, whether it is size or resistance. Once these values have been verified by the design specification, you can rest a
PCB assembly projects require a myriad of specifications. Of course, manufacturers can make high quality PCBS, but even the best boards must meet customer requirements to be useful. Documentation packages protect both parties and make assembly as smooth a
Transforming your design into a complete physical structure requires three steps: 1) manufacturing, 2) component procurement and 3) assembly. Printed circuit board assembly or PCBA is one of two PCB manufacturing processes. The other stage is manufacturin
The RCD buffer circuit consists of resistor (Rs), capacitor (Cs) and diode (VDs). Resistors (Rs) and diodes (VDs) can be connected in series or parallel. Its main function is to suppress the overvoltage generated when the device is turned off and limit du
Three types of switching power buffer circuitsThe LCD buffer circuit consists of inductors Lr, capacitors Cs, Cr and diodes VD1, VD2, VD3. Since LCD buffering does not use active devices and contains no energy-consuming components, it produces almost no l
Matching resistance selection principle: The sum of the matching resistance value and the output impedance of the driver is equal to the characteristic impedance of the transmission line. The output impedance of common CMOS and TTL drivers will vary with
The external processing of three anti-paint is bound to cause the continuous transfer of PCBA, which is easy to cause collision, ESD electrostatic breakdown and other potential defects. PCBA factories need to be equipped with three anti-paint spraying pro
Customers place orders to PCBA processing plants according to their actual needs and put forward specific requirements. The processing plant will evaluate its capacity to see if it can fulfill the order. If the manufacturer is sure that they can complete
Drilling: The use of all imported precision high-speed drilling machine, large production area, 8-axis drill at the same time drilling, efficiency and quality at the same time to ensure the auxiliary process to ensure the roughness of the empty wall, conv
Main topology and application of energy storage module converterThere are many topologies for energy storage converters, including low-voltage two-level and three-level topologies, as well as advanced H-bridge cascaded and MMC topologies. The power conver
When SMT components are placed, connectors are placed first, followed by power circuits, sensitive and precision circuits, critical circuit components, and any other required components. You are selecting route priorities based on power level, noise sensi
