PCB Assembly Heart meter control board



Description:


Due to the large number of components, the wide variety and the short life cycle of electronic products, the PCB Assembly Suitable For Electronic Products has brought great challenges to production operation scheduling. Multi-variety, small batch and variable batch have become the mainstream production mode of electronic manufacturing. In this mode, the switching time between multiple varieties occupies a larger and larger proportion in the entire assembly time.

Matters need attention :
To increase the lifetime of solder joints, the method of solder paste pre-overlaying on PCB solder pads is proposed. Meantime, process parameters are controlled to ensure the assembly quality.
