The traditional PCB design goes through the process of schematic design, layout design, PCB production, measurement and debugging.In the schematic design stage, due to the lack of effective analysis methods and simulation tools, pre analysis of the transmission characteristics of signals on actual PCBs is required. The design of the schematic can generally only refer to component data manuals or past design experience. For a new design project, it may be difficult to make the correct choices for...

Since the development of SMT surface mount processing industry, some commonly used terms within the industry have also been widely circulated. As a beginner, it is essential to have an understanding of specialized terminology in the electronic processing industry. It has the characteristics of high assembly density and small product volume. Next, we will introduce the relevant content in detail.1、 Common terms for circuit board mounting1. Ideal solder joint:(1) The surface wettability of the sol...

SMT surface mount processing factories indicate that there are many equipment required for SMT surface mount processing, such as solder paste printing machines, surface mount machines, reflow soldering, AOI detectors, and so on; In addition, if touching the touchpad with bare hands or causing a decrease in the adhesion of green oil, bubble detachment, and other effects; So now let me introduce the relevant content in detail for you.1、 Equipment required for SMT surface mount processing1. Solder ...

The ineffective solder joints in PCBA processing are due to poor positioning of electronic components, poor quality of soldering flux, unqualified residue, and air oxidation; Another way to control quality is to submit a manufacturability report (DFM) based on different customer needs. Next, let me introduce the detailed content to you.1、 Why are solder joints ineffective in PCBA processing1. Poor positioning of electronic components: coating, environmental pollution, air oxidation, and common s...

There are many operating rules for PCBA processing, such as not having unrelated debris on the workbench, keeping the workbench clean, not holding PCBA patches with hands, strictly following the process operation, etc. During processing, it is also important to understand commonly used labels and regularly maintain the equipment. Therefore, the following will provide a detailed introduction to the relevant content.1、 Operation rules for PCBA processing1. There should be no food or beverage in th...
