The selective soldering application requires a combination of performance attributes that traditional liquid fluxes designed for wave soldering applications cannot fulfill. First, the flux deposition on the board needs to be carefully controlled. Proper fine tuning of the flux physicochemical characteristics combined with a process optimization are mandatory to strike the right balance between solderability and reliability. However, localization of the flux residue through the drop jet process is not enough to guarantee the expected performance level. The flux needs to be designed to minimize the impact of unavoidable spreading and splashing events.From this perspective a fundamental understanding of the relationships between formulation and reliability is critical. In this application, thermal history of the flux residues (from room temperature to solder liquidus) is a key performance driver. Finally, it is necessary to conduct statistically designed experiments on industrial selective soldering machines in order to map the relationships between flux characteristics and selective process friendliness.

SHENMAO Features a new Sn-3.0Ag-0.5Cu Lead-Free Solder Paste PF606-P133H for laser soldering applications. Dispensed from syringes, it is developed for automatic laser soldering processes in the packaging and assembly of surface mount devices and microelectronics. Laser energy is applied at the precise location in a non-contact procedure to create high shear strength well-formed solder joints during the lower thermal stress process while reducing intermetallic formation. PF606-P133H solder paste produces minimal flux residue and no-splash or solder balling issues. It is well suited for high yield soldering of sensitive electronic components in manufacturing or repair of electronic devices that can-not tolerate conventional reflow-oven temperature.
