Small batch PCBA assemblyThis is the process involved in PCBA production and assembly by reducing costs while ensuring high quality is maintained. Here, the processes employ various techniques to maintain quality and keep costs down.Techniques used to sec
Surface assembly method of PCBA processingElectronic OEM foundry is also a relatively common processing cooperation method in today's electronic processing industry, which can indeed save a lot of trouble for R&D companies. PCBA processing is the main...
PCB manufacturing principle processThe manufacturing process of PCB is relatively complicated, and there are many process requirements. In fact, there are many specific manufacturing processes on the Internet. Let’s talk about the principle of PCB. PCBs a
SMT chip technology processThe SMT patch process is divided into: solder paste printing, SMT patch, intermediate inspection, reflow soldering, post-stove inspection, performance test, and repair.SMT patch process flow chart1. Solder paste printing machine
In high speed, high density PCB design, a complete ground plane is generally provided, so that each signal line basically only interacts with its nearest signal line, and the cross coupling from other distant signal lines can be ignored.
The ADP5520 consists of an asynchronous boost converter, a programmable ambient light management circuit, a state machine, and a configurable port extender that can further save system resources.
Introduction to flexible PCB materialsFlexible PCB materials need to support multiple design and operational goals: static or dynamic bending, ability to pass standard assembly processes, support simple manufacturing procedures, and achieve high yields. F
PCB DesignFlexible Circuit Design Overview Examines the stress concentration properties of a design. The stress concentration properties are the sole cause of mechanical failure (i.e., cracked/broken conductors, torn insulation, etc.) in flex cir
Electronic components procurement knowledge and processGenerally speaking, supplier development includes: analysis of supply market competition, finding qualified suppliers, evaluation of potential suppliers, inquiry and quotation, negotiation of contract
High-frequency and high-speed PCB design 1. After the PCB design is completed, how to choose the PCB board?The choice of PCB board must strike a balance between meeting the design requirements, mass production and cost. Design requirements contain both el
Summary of experience in PCB stack-up design1. PCB compositionPCB contains two important components: Core and PP (Prepreg, semi-solid sheet).Both surfaces of Core are covered with copper foil, which is used as a conductive layer, and the solid material is
Impedance PCB stack design and characteristic impedance calculationImpedance PCB stack design is one of the necessary skills for hardware engineers and PCB engineers. Layout engineers will carry out layout design based on the stack design, including setti
