Abstract:
1. A method for beam soldering a first component to a second component using a beam of light emitted from a light source to reflow adjoining pairs of solder pads on said first component and said second component, wherein material between adjacent solder pads on at least one of said first and said second components is absorptive of a spectrum of said light, the method comprising: directing said beam of light through a filter to a plurality of said adjoining pairs of solder pads on said first component and said second component wherein said filter is exchangeably connected to a beam fixture; and filtering wavelengths shorter than approximately 440-480 nm from said beam, to remove wavelengths which would otherwise damage, via absorption, said material between adjacent solder pads on at least one of said first and said second components.
