Obtaining high quality VLSI packages with QFD

Component end users want a high quality, reliable part. However, the expected failure rate, cost etc. may vary from one customer to the next. The amount of control that a packaging vendor is expected to put in place so that he can meet those requirements can be assessed through the implementation of QFD (quality function deployment). One such work effort that strives to use this technique for the definition and subsequent optimization of these controls for delivering high quality PQFP´s (plastic quad flat packs) is described
