Application experience To do the product development process more effective and efficiently, QFD (quality function deployment), TRIZ (invention and conception method), and QE (quality engineering) were executed in-house as one of the knowledge creation processes. However, because the secret matter related to a detailed design is a lot of, QE is excluded from this report. Period : From June to November, 2011 Number of themes :2 (SAP and ITO) The number of men :15 each theme people (business, production, technology, and market) Days :Program of 11 days (QFD 4 and TRIZ 7) 7
Case: SAP (Semi-Additive Process) Development background: Semiadditive process (SAP) that is one of the plater methods is used for the high density package substrate. However, there was not the technology that was able to SAP process propose it by our company, and original technological development was demanded. Development goal: Line thinning Line & Space 5μm or less of substrate 8 Line and nd S Space is the o he one ne tha hat the he co copper ci circuit a and nd the he ci circuit g gap distance w wer ere s sho hown.
QFD, TRIZ, and (QE) are used 1.Attractive commodity design that makes customer's potential needs by QFD visible ・ It designs according to Kanoh model *. ・ The trade-off is understood without “Drop/Leak”, and the risk is minimized. ・ It uses it as a communications tool. 2.Attractive commodity concept creation by idea creation by TRIZ ・ Attractive concept creation ・ Product development that doesn't compromise ・ Idea creation tool 3.Improvement and efficiency improvement of perfection of product by QE(TM) ・ The optimum design will be made highly effective in a short time. ・ Prior grasp when parameter is changed ・ Robust design - The quality is thought, and defined not to become an updated version product alone that collects negative information about customers in the attractive quality element (It satisfies, it doesn't fulfill, and do not exist if fulfilled either), the unified quality element (It is dissatisfied because of the satisfaction and no fulfillment if fulfilled), and the natural elegance quality elements (It is dissatisfied because of natural and no fulfillment if fulfilled). (This is 9 called a Kano model. )
Eight problems that engineer faces QFD TRIZ Taguchi method ① Awareness of customer's needs - - - ② Setting of attractive commodity concept - - - ③ It is easy to use and is a daring design. - - - ④ Faster time to market - - - ⑤ Solution of published market quality - - - - problem ⑥ Solution of bottleneck technology - - - ⑦ Decrease of cost - - - ⑧ Expansion of intellectual property - - - - :Immediate effect *: indirect effect Application of each problem of development and design approach - It is general to apply the quality control method of FMEA and FTA. 10
Procedure of QFD (VOC⇒ technology conversion) < making of quality table > The cause is ① Collection and analysis of analyzed primitive information 6/15 with TRIZ . ④ Conversion into demand for [consultant] Primitive information 1 VOC Quality property quality ② Making of demand for ① quality spread sheet 7/4 ③ Examination of quality [consultant] ③ Demand for quality 2 Planning Division ⑥ Quality project ② ④ Extraction and Dual table arrangement of quality 7/25 property [consultant] ⑤ Quality design 3 ⑥ Demand-characteristic relation ⑤ Quality design To TRIZ to achieve the decided quality It solves it design with TRIZ 11 VOC=Voice of customer

Procedure of TRIZ ① :Making of problem essence ② :Observation and conception because of various angles Function-attribute analysis Cause-consequence analysis TRIZ Embarrassed thing When seeing from side when seeing on More in detail when dividing into two When sideways cutting it when cutting it in length When making it to asymmetry Primary cause The good one arises when hundreds of ideas are shown. ④ :Strategy Development theme decision ③ :Making of idea (idea settling) effective Selection and uniting of concepts Uniting Ideas are united mutually and the quality is improved further. Next, it thinks about reality. 13
TRIZ program Theme decision Making of problem Cause result essence Function attribute Contradiction analysis (extraction of analysis characteristic primary cause) Cause extraction Idea putting out Idea putting out Idea putting out Idea 172 ideas by Prediction by principle of separation by Principles putting out by TRIZ Emanation Arrangement of idea Idea uniting and concept selection of each subsystem Making of idea effective (selection and connection) Settling Selection of concept of main system Absolute grading Absolute grading of the final system of system concept Commodity concept selection after 14 five years in one year in 2-3 years
15 Function attribute analysis The intricate web of ties is hidden on the side where plating is put up and the put side. The process of SAP is made a diagram, and the causal relation of the each stage of work is clarified. The one that it is possible to become a primary cause is made easy to look for. 15
16 Cause result analysis Embarrassed thing The insulation reliability is not obtained. Cause ⑤ There is the etching remainder of copper. Pd remains. Because Pd is used There are a lot of causes of originating Cause ④ The surface in palladium. tensity of the Pd removal liquid is Primary cause ① not lowered. The ruggedness on A strong oxidant cannot be used There is a resin. the surface in the because of the palladium removal. Smear removal is a It makes it bluntly problem. by the desmear. Cause ③ Cause ② Sticking of resin and The resin smear is chemical copper generated. 16
Uniting of ideas by TRIZ Various ideas were emanated, and it evaluated in the point of QCD, 17 ideas were united, and the road map and the concept were created. Semi-additive process where D cutting process was included Electroless copper Ditch switching off Beer filling Hole opening Surface Desmear cutting Catalyst Process giving shortening Insulation reliability amount 17
