Abstract:
A method for forming a solder joint for electrically and mechanically coupling connection surfaces of first and second electrical devices, the method comprising the steps of:applying solder to the connection surface of at least one of the first or second electrical devices;using a mechanical fixture to position the first and second electrical devices so that a gap exists therebetween and so that the solder applied to the connection surface of the one electrical device is substantially aligned with the connection surface of the second electrical device;applying a fluid adhesive between the first and second electrical devices;inserting an adhesive blocker between the first electrical device and the second electrical device and proximate to the connection surfaces of the electrical devices to block the fluid adhesive from flowing onto the connection surfaces;applying heat to reflow the solder between the connection surfaces; andcooling the reflowed solder into a solidified solder joint between the connection surfaces.
