Introduction of common assembly techniques for PCBA model patch

PCBA model patchThe knowledge involved is very extensive. For example: manufacturing and assembly technology of electronic components, circuit design, welding technology, selection of mounting materials, etc.; in addition, it is also necessary to master the technology of cleaning, testing and maintenance of components. According to the different assembly methods of PCBA model patch, there are mainly the following common assembly techniques:

Full surface assembly technology. The full-surface assembly method of PCBA template patch means that all components are assembled by patching on the PCB board, regardless of the single-sided or double-sided of the board. This component assembly method has the characteristics of simple process, small size, light weight of assembly parts and high assembly density. It is a more technical type used in PCBA sample patch.

Single-sided hybrid assembly technology. The single-sided hybrid assembly technology of PCBA template patch refers to the mode of hybrid assembly of patch components and plug-in components on a single side of the PCB board. This kind of component assembly method is more complicated because some components are through-hole plug-in type. This assembly technology of PCBA template patch is generally applied to relatively special electronic products.

Double-sided hybrid assembly technology. The double-sided hybrid assembly technology of the PCBA template patch includes two situations: one is in the PCB board, the components on one side are welded and assembled by the plug-in method; the other side is welded and assembled by the SMT patch technology; the other is in the PCB The components used on each side of the board include both patch components and plug-in components. The welding position of the patch component is on the same side as the component, and the welding position of the plug-in component is on the back of the component. Therefore, this assembly method requires PCBA sample chip manufacturers to have a very high level of craftsmanship.
