How To Choose Components For HASL SMT Assembly?

HASL Smt PCB Assembly Manufacturers 6oz One Stop PCB Assembly 0

1. The Heat Resistance of The Components

Due to the high melting point of lead-free solder, one of the characteristics of the SMT lead-free (HASL) soldering process is the high soldering temperature, which brings about the problem of heat resistance of components. Therefore, when evaluating component suppliers in the PCBA lead-free process, it is not only necessary to evaluate whether they use toxic and harmful substances, but also the heat resistance of the components. Apparently, different components have different heat resistance modes. Some are impact-resistant but not high-temperature resistant, and some are high-temperature resistant and not impact-resistant; The temperature resistance curve of components is not equal to the soldering temperature curve. If not attention, it will damage certain component.

2. The Compatibility of Solder & Component Surface Coating Materials

In lead-free soldering, the types of component soldering end coating materials are the most complex. The types of surface plating on the solder end of lead-free components include pure Sn, Ni-Au, Ni-Pd-Au, Sn-Ag-Cu, Sn-cu, Sn-Bi and other solder alloys with different alloy layers; Therefore, their interface reaction speed various, the resulting brazing seam structure is different, and the reliability is also different. Due to the variety of electronic components and the complex plating of the component soldering ends, there may be a mismatch between the soldering ends of some components and the solder, causing reliability problems.
