BOSTON – SMTA Boston is hosting two webinars Feb. 9, hosted by REStronics.

Michael Sivigny, general manager of CeTaQ Americas, will discuss hidden problems affecting SMT quality. The technical presentation will cover individual process step characterization methods with real examples of improvement that contribute to DPMO reduction.

In stencil printing, the validation method considers accuracy of the alignment system and dynamic measurement of squeegee force. During placement, accuracy and placement Z-force are looked at to calibrate head/angle offset associations and dynamically check individual spindle forces and energy dissipation. While each process step is characterized, the underlying objective is to verify OEM specifications and prove machines are capable of intended quality performance. This allows engineers to streamline efforts and focus on other areas of defect contribution.

Through diagnostic measurement and analysis of SMT equipment, quality performance improvement can be realized. Measured mean values can be used to soft calibrate machines to a higher level of accuracy than available through OEM standard calibrations.

When machines are allowed to run in maximum accuracy mode, they are more confident and capable of producing today's high-reliability electronics with fewer defects. Defect contribution in each process step needs detailed analysis to reduce cost. When costs are minimized, the underlying inherent process efficiencies go up, which contributes to higher productivity and bottom-line profitability. The improvement effects of process optimization have a number of intrinsic benefits that can maintain high manufacturing productivity.
