Abstract:
1. Clamping apparatus for clamping a plurality of circuit boards to the carrier wall in the inside region of the housing of an electronic module during reflow solder processing to attach said circuit boards to said carrier wall, said inside region including metal walls upstanding from said carrier wall and defining a plurality of compartments, each respective compartment being the location for at least a respective one of said plurality of circuit boards, comprising: a particulate, said particulate being sufficient in number to fill said housing and cover said plurality of circuit boards without covering said upstanding metal walls of said inside region of said housing; a sheet of foam material, said sheet being sufficient in size to cover an open end of said housing; a rigid plate, said rigid plate being sufficient in size to cover said sheet of foam material; and clamping means for applying a compressive force between said carrier wall and said rigid plate to compress said sheet of foam material against said particulate and force said plurality of circuit boards against said carrier wall for reflow soldering of said circuit boards to said carrier wall.
