Advantages and Disadvantages of Surface Mounting Technology

Introduction:Surface-mount technology (SMT) is a method for producing electronic circuits in which the components are mounted or placed directly onto the surface of printed circuit boards (PCBs). An electronic device so made is called a surface-mount device (SMD). In industry, it has largely replaced the through-hole technology construction method of fitting components with wire leads into holes in the circuit board. Both technologies can be used on the same board, with the through-hole technolo...


PCB Requirements for Typical SMT Equipment

Introduction:There are many types of SMT equipment. How to make the design of PCB meet its requirements is decided by the type of equipment. The basic requirements of typical SMT equipment to PCB in China are summarized as follows.Edge (Break-away tab):PCB in the process of SMT equipment is generally completed by rail transportation. When locating in equipment such as patch machine and wave soldering, it is guaranteed that it can be fixed reliably. Generally, more than 5mm should be reserved at ...


The Main Factors Affect the Quality of SMT Soldering and Its Solutions

Abstract: SMT process as the core of the electronic assembly process, the welding quality affects the overall quality of the products. For SMT industry, high quality welding quality is the basis of products, and the capital and leverage for products to compete with others. The following are some main factors affecting SMT welding quality.Materials:As one of the important components of SMT, the quality and performance of materials directly affect the quality of backflow welding, so that the follo...
