Method for a universal flux-printing squeegee design with an adjustable angle, blade overhang, and an interchangeable blade mounting structure

                 Disclosed is a method for a universal flux-printing squeegee design with an adjustable angle, blade overhang, and an interchangeable blade mounting structure. Benefits include improved throughput.

Background

              High cost and long through-put time are required to design and fabricate multiple dedicated squeegees to match the characterization requirement, such as different blade angles, overhang, and thickness. The conventional solution to this problem is the fabrication of multiple squeegee designs for the various requirements.

General description

              The disclosed method is a universal flux-printing squeegee design with an adjustable angle, blade overhang, and an interchangeable blade mounting structure for effective process characterization.

              The key elements of the method include:

·        Adjustable blade angle through a pivoting joint between the main structure and blade support frame

·        Adjustable overhang, with slotted mounting of blades

·        A removable blade mounting structure, enabling blade interchangeability for material and thickness variation

Advantages

              Flux printing full-process characterization can be achieved using a single squeegee to simulate multiple key process inputs.

Detailed description

              The disclosed method uses a universal squeegee design concept that has two features, adjustable blade angle and overhang height. This design enabl...
