9 th TRIZ symposium

Meltex, Inc. Tajima

QFD and TRIZ Case Studyin Surface Treatment Chemical23456Application experience
To do the product development process more effective
and efficiently, QFD (quality function deployment), TRIZ
(invention and conception method), and QE (qualityengineering) were executed in-house as one of theknowledge 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)

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 topropose it by our company, andoriginal technological development
was demanded.

SAP process

Development goal:Line thinning Line & Space 5μm orless of substrateLine and Space is the one that the copper circuit and the circuit gap distance were shown.8

QFD, TRIZ, and (QE) are used
1.Attractive commodity design that makes customer's potential needs by QFDvisible･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 byQE(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), andthe natural elegance quality elements (It is dissatisfied because of natural and no fulfillment if fulfilled). (This iscalled a Kano model. )9Eight problems that engineer faces

Function-attribute analysis
Cause-consequence analysis
Embarrassed thing

Primary cause

TRIZ
When seeing from side when seeing onMore in detail when dividing into two
When sideways cutting it when cutting itin length
When making it to asymmetry

The good one arises when hundredsof ideas are shown.
④:Strategy
Development theme decision③:Making of idea (idea settling) effective

Uniting

Selection and uniting of concepts
Ideas are united mutually and the quality is improved further.
Next, it thinks about reality.

15

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 eachstage of work is clarified.
The one that it is possible to becomea primary cause is made easy to lookfor.

Cause result analysis

Embarrassed thing

The insulation reliability is
not obtained.

Cause ⑤

There is the etchingremainder of copper.

Pd remains.
Because Pd is used
Cause ④The surface
tensity of the Pd
removal liquid is
not lowered.

Primary cause ①

A strong oxidant cannot be usedbecause of the palladium removal.

Cause ③

There is a resin.
It makes it bluntly
by the desmear.

Sticking of resin andchemical copper

Cause ②

There are a lot ofcauses of originatingin palladium.
The ruggedness on
the surface in theSmear removal is aproblem.

The resin smear isgenerated.

Result and failure
Result･The concept can be created from VOC by a chain of flows by QFD and TRIZ
(Even the normal person :).
･The solidarity and communications can be attempted by sharing the place.
･It comes in the place of study from which old-timer's technology is instructedto the young man by the group examination.
･Shortening of development time･Drop/Leak prevention (making to visible)･The specific customer's influence is not received easily.
･Lack information is understood.
Improvement･The idea of man who is well versed in the field contributes greatly.
･The person who doesn't make remarks that there are a lot of numbers ofpeople comes out.
･There is a negative employee because taking time to make arrangements
and the content are complex.
･The number of ideas depends on the ability.
