Abstract
A boat is formed with a plurality of through-holes sized to securely maintain ceramic or organic flip chip semiconductor packages in place during assembly. Embodiments comprises a boat having a bottom layer with an array of four-sided through-holes and a top layer with an array of through-holes and tabs extending from the sides of the through-hole. Embodiments further include a boat having a bottom layer with through-holes smaller than substantially aligned overlying through-holes in the top layer, the substantially aligned through-holes forming flip chip package holding pockets. An alignment mechanism ensures that components are accurately positioned on flip chip packages held in the boat during assembly.
