1. Single-sided mounting process Single-sided mounting means that the components are all mounted components, and the components are assembled on one side of the PCB. The main process of single-sided placement process: printing solder paste → patch → reflow soldering → cleaning → detection → rewor...
The printed circuit board adhesive is also a pcb assembled red plastic, usually a red (also yellow or white) paste uniformly distributed with a hardener, a pigment, a solvent, etc., mainly used for the patch processing element. The device is attached to a printed board and is typically dispensed ...
The miniaturization, light weight and diversification of functions in the electronic field are the driving force and source of SMB development. Typical examples are mobile phones. Technology is pushing SMB manufacturing technology to the following direction: (1) High precision of pcb assembly. (2...
