Circuit boards are the carriers of electronic circuits. Any circuit design needs to be installed on a circuit board to realize its function. Processing circuit boards is the most headache for amateur electronics enthusiasts. It is often the case that the circuit is designed in half a day, but it takes several days to process…
From the current and future application and development prospects, the application of inkjet printing technology of fully printed electronics in PCB is mainly reflected in the following three aspects: application in pattern transfer; application in embedded passive components; application in fully printed electronics (including packaging) that directly forms lines and connections. These applications will bring…
For an instrument with excellent performance, in addition to selecting high-quality components and reasonable circuits, the correct structural design of the component layout and electrical connection direction of the printed circuit board is a key issue that determines whether the instrument can work reliably. For circuits with the same components and parameters, different results may…
With the advancement of electronic technology, the complexity and application scope of PCB (printed circuit board) have developed rapidly. Designers engaged in high-frequency PCB must have the corresponding basic theoretical knowledge and rich experience in high-frequency PCB production. In other words, whether it is the drawing of the schematic diagram or the design of the…
The interconnection of the circuit board system includes three types of interconnection: chip to circuit board, interconnection within the PCB board, and between the PCB and external devices. In RF design, the electromagnetic characteristics at the interconnection point are one of the main problems faced by engineering design. This article introduces various techniques for the…
Efficient parallel circuit board design can be accomplished using newly developed software technologies. This new technology enables multiple designers, multiple processes and different types of tools to work simultaneously on the same design database, significantly improving design productivity. Unlike the traditional method of dividing the design into several parts and completing each part independently, this…
General principles of PCB design Content: Printed circuit board (PCB) is the support for circuit elements and devices in electronic products. It provides electrical connections between circuit elements and devices. With the rapid development of electronic technology, the density of PCB is getting higher and higher. The quality of PCB design has a great impact…
(I) Challenges faced by electronic system design With the large-scale increase in system design complexity and integration, electronic system designers are engaged in circuit design above 100MHZ, and the operating frequency of the bus has reached or exceeded 50MHZ, and some even exceed 100MHZ. Currently, about 50% of the designs have a clock frequency exceeding…
1.Impedance matching Impedance matching refers to a suitable matching method between a signal source or transmission line and a load. According to the access method, impedance matching can be divided into two types: serial and parallel; according to the signal source frequency, impedance matching can be divided into low frequency and high frequency. (1) Serial…
For the new PCB board that has just been brought back, we must first roughly observe whether there are any problems on the board, such as whether there are obvious cracks, short circuits, open circuits, etc. If necessary, you can check whether the resistance between the power supply and the ground wire is large enough….
This article explores the key factors influencing printed circuit assembly prices, examining material costs, labor rates, production volume, and market trends. Gain insights into pricing strategies and navigate the competitive landscape effectively.
Introduction: In PCB routing design, there is a complete set of methods to improve the routing rate. Here, we provide you with effective techniques to improve the routing rate and design efficiency of PCB design, which can not only save customers project development cycle, but also maximize the quality of the finished design. 1.Determine the…
Discover how innovative turnkey PCB assembly solutions can streamline production processes across various industries, ensuring quality, efficiency, and cost-effectiveness while meeting diverse project requirements seamlessly.
1.Brushing boards The materials provided by the previous process (i.e. production boards) are required to have no serious oxidation, oil stains, or wrinkles on the board surface. We use pickling (5% sulfuric acid) spraying to remove organic impurities and inorganic dirt, and then use a 500-mesh nylon brush roller to brush. After brushing the board,…
With the continuous increase in the production ratio of soft PCBs and the application and promotion of rigid-flex PCBs, it is now more common to add soft, rigid or rigid-flex when talking about PCBs and then say how many layers it is. Usually, PCBs made of soft insulating substrates are called soft PCBs or flexible…
