EFD Inc. and Leister USA have collaborated to bust the myth that you cannot perform laser reflow with solder paste. Using Leister diode lasers, EFD has formulated solder pastes that survive the rapid reflow cycle typical of laser heating. These solder pastes reflow and wet well, without spatter, even when heating is accomplished in less than half a second. The flux core in wire solders cannot boast such flux spatter resistance in such an aggressive heating environment.

With the use of laser light for reflow having been established, all that remains is to apply it to best effect. Each time a laser is fired, it pumps a specific amount of energy at a particular wavelength to a particular point in space. Where technique comes in is choosing where and for how long to apply that light along with the application of accessory equipment to optimize solder paste reflow. This presentation covers the specifics of how to determine which process choices are the right process choices based on the needs of your product to maximize yield and throughput.
