Method for a manual flux print tool for carrierized packages

Disclosed is a method for a manual flux print tool for carrierized packages. Benefits include improved functionality, improved reliability, improved throughput, and improved ease of implementation.

Background

        � � � � � No conventional method exists for printing flux onto substrates in a controlled and consistent manner when testing offsite where no screen printer is available.

        � � � � � Placing flux on a substrate and scraping across the package using a plastic card causes a nonuniform flux print (see Figure 1).

General description

        � � � � � The disclosed method is a manual flux print tool for carrierized packages. A metal plate holds a carrier and stencil in place for a squeegee to print across the substrates. Slotted nonstick guides provide stability and assure a repeatable squeegee pressure is applied.

        � � � � � The key elements of the method include:

•        � � � � Metal holder

•        � � � � Clamp mechanism

•        � � � � Stencil

•        � � � � Modified squeegees and guides

        � � � � � A stainless steel base (A, see Figure 2) is countersunk to allow a carrier (B) to sit inside of it. Another part (C) fits inside and clamps a thin metallic stencil (D) to the carrier. Two slotted nonstick blocks (E) ride along the outside edge of the clamped mechanism and provide stability and support for the squeegees (F). These guides are adjustable and can be used to control the force applied to the stencil to regulate the thickness of the...
