Advanced Nano Coating
Presenter: Brent Nolan, Stentech
With the continued miniaturization of electronic packaging, the challenge continues to be the ability to get enough solder paste down in the right geometry shape to not only place the component to solder, but also to meet the ever-changing IPC requirements.

Stencil Cleaning Best Practices
Mike Bixenman, Ph.D., KYZEN Corporation
Stencil printing solder paste is a well-known and proven process technology for surface mounted components. Solder paste deposition on fine pitch and area array packages offer an attractive, cost-saving, and high-volume production alternative. The cleanliness of the stencil is critical to the success of the stencil printing process. Insufficient solder is the primary cause of defects originating from the stencil printing process; therefore, stencil cleanliness is an essential process step for delivering the proper amount of solder paste to the PCB pads. Stencil cleaning must remove all solder particles and flux vehicle from stencil apertures without damaging the stencil, bonding adhesive or mounting mesh.
The degree of cleanliness required varies with complexity of the board design. Stencils are usually cleaned to a visually clean condition. The stencil cleaning objectives are the removal of contaminants in the form of non-reflowed solder paste, flux
residues, uncured adhesives, and other process residues. The purpose of this presentation is to review Best Practices for cleaning at the stencil printer and once the printing process is completed.
