1. Price: Many manufacturers require that the price should not be higher than 63Sn/37Pn, but at present, the finished products of lead-free substitutes are 35% ……

Lead free process: a basic concept of lead-free electronic assembly is that in the soft soldering process, no matter manual soldering, dip welding, wave soldering or reflow soldering, the solder used is lead free solder. Lead free solder does not mean 100% lead free solder. In lead solders, lead exists as a basic eleme……

SMT processing technology can not only make the entire electronic product small, but also make the size of the circuit board smaller, so the smaller parts can make the overall product smaller. In the production of high-end products, the application fields of these parts are very wide, so it is helpful for the emergence……

With high assembly density, small size and light weight of electronic products, the volume and weight of SMT components are only about 1/10 of those of traditional plug-in components. After SMT is generally used, the volume of electronic products is reduced by 40%~60%, and the weight is reduced by 60%~80%.

SMT refers to surface mount technology, also known as surface mount or surface mount technology, which is a popular technology and process in the electronic assembly industry. The basic process flow of smt includes solder paste printing, part mounting, reflow welding, AOI optical detection, maintenance and plate separa……
