Generally, before the SMT PCB Assembly/SMT patch processing is processed, in order to produce smooth production in order to ensure that it can be completed on time, some preparations need to be prepared before formal production: Preparation For SMT PCB Assembly Before Processing.
PCB Assembly Specification
SMT PCBA Introduction
SMT PCB Assembly means Surface Mount Technology, known as a a kind of Circuit assembly technology that installs the SMC/SMD (named Chip Components in Chinese) on the surface of Printed Circuit Board or on the surface of other substrates, which is solded and assembled by means of reflow soldering or dip soldering. It realizes high density, high reliability, miniaturization and low cost of electronic product assembly.
SMT is a flexible and powerful assembly process that has allowed manufacturers to produce modern devices with ever-smaller footprints
