Abstract:
1. A method of joining a first substrate to a second substrate, the method comprising: ascertaining a deviation from a nominal gap between the first substrate and the second substrate at a first region of the first substrate; binning the first substrate according to the ascertained deviation; determining a volume of solder paste necessary to compensate for the deviation from the nominal gap; selecting from amongst a plurality of adapted stencils, an adapted stencil for applying solder paste to the first substrate, the selection being based upon the bin in which the first substrate is binned; applying the volume of solder paste necessary to compensate for the deviation at the first region of the first substrate; and bonding the second substrate to the first substrate using, at least in part, the solder paste applied at the first region of the first substrate.
