A method for coupling a lid to a support substrate having a semiconductor chip coupled thereto and a clamp fixture. Each semiconductor component has a semiconductor chip mounted to a semiconductor component and a lid coupled to the support substrate via a lid attach material. The lid attach material is cured either using a two-step process that includes a partial cure step followed by a clampless cure step or by curing the die attach material in a clamp fixture without including a pre-cure step. The semiconductor component manufacture decides on the curing approach based on cost and the number of semiconductor components being manufactured. If the semiconductor manufacturer opts for curing with a clamp fixture, the clamp fixture includes a base plate insert on which the semiconductor components are placed and a compression mechanism that includes a compression plate having a compressive material disposed thereon.

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.
