In surface mount technology (SMT), internal voids in solder joints are one of the main defects affecting the reliability of electronic components. Voids can weaken the mechanical strength, conductivity, and thermal conductivity of solder joints, which may lead to catastrophic failures, especially in high-reliability fields such as automotive electronics and aerospace. This article systematically analyzes … Read more
Click the blue text to follow us Recently, I took on an urgent repair task; a control board had multiple broken fly wires, and the client requested a repair within 24 hours. This posed a challenge for me, as 0.1mm enameled wire is difficult to handle under a microscope, not to mention ensuring reliability. However, … Read more
Metal core multilayer printed circuit boards, as the name suggests, are multilayer boards with an embedded0.1mm~1.5mm thick metal core (such as Cu,Al,Cu-Invar-Cu etc.), widely used inLED lighting, high-performance computing, automotive electronics, and other fields. Metal core multilayer boards have the following specific functions: l High Power Heat Dissipation The core components of ordinary printed circuit … Read more
Conformal coatings were originally applied only in high-tech fields of printed circuit boards (automotive industry, aerospace, and maritime). As electronic devices are increasingly used in daily life, consumers are also paying more attention to product quality and reliability. The use of conformal coatings allows manufacturers to effectively improve product quality, and thus they are now … Read more
The residues from soldering electronic integrated circuit boards that are not thoroughly cleaned can lead to serious consequences in multiple aspects, mainly involving electrical performance, chemical corrosion, and mechanical reliability. The specific analysis is as follows: 1. Deterioration of Electrical Performance Short Circuits and Leakage Current Issues The conductive ions (such as halogens and organic … Read more
1. Types of PCBs According to the number of circuit layers, PCBs can be classified into single-sided boards, double-sided boards, and multi-layer boards. Common multi-layer boards typically have 4 or 6 layers, while complex multi-layer boards can have dozens of layers. The following are the three main types of PCBs: 1. Single-Sided Boards Single-sided boards … Read more
