New wafer bumping stencil boosts yields
Electroformed wafer-bumping stencils from Tecan Stencils Limited (TSL), are being used to accurately deposit solder paste directly onto silicon wafer die.
Multi-level stencils for improved PCB manufacture
TSL manufactures multi-level stencils which deliver the distinct paste volumes required by the diversity of components used on today's electronic assemblies in a single printing action.
Every stencil is checked for aperture existence and every aperture is checked for conformance to required physical dimensions, shape and positional accuracy.
Whether a simple single-thickness stencil, or more complex fine-pitch requirement, the system facilitates total verification of the final product.
"As customers' printing requirements depend on the quality of the stencil, we believe that the ScanCheck measurement system is crucial in guaranteeing the printed results required.
It is the only system to offer both image verification and accurate inclusive aperture measurement in a single scan", said stencil division manager, Tony Weldon.
"As evolving technology results in smaller component packages and lead pitches, it is vitally important to guarantee stencils continue to provide effective printing solutions.
The system is designed to provide accuracy with speed and can fully inspect two million apertures on a wafer-bumping stencil in approximately ten minutes, using a resolution of 12,000dot/in.
Having an effective scanning area of 470 x 660mm allows both large single images and multiple images to be fully accommodated in one single scan, while maintaining an accuracy of +/-10um, across the entire bed.
The scanned data for each stencil is retained in an archive and a stencil quality report can be provided.
All Tecan stencils are manufactured in accordance with both the customer's requirements and internal ISO9002 quality control procedures.
