Business Case
Chrysler is the biggest customer for XXX factory. TIPM for Chrysler
has been launched since end 2006. It is brand-new design product
for Continental/Tianjin, which has two sides pin on the top and
bottom PCB slide. As the pin straightness (perpendicular to the
board) is very important to customer assembly process, therefore
Tianjin factory install AOI test for inspection, but the first time yield
FTY% can’t meet the target which is above 96%.
Opportunity Statement
If we can meet FTY target 96%, we can
achieve saving at least 200k and meet
customer requirement accordingly. On time
delivery will also be assured.

The complaint pin use the mechanical connective design, The tail of complain pin directly
contact PCB through hole without any soldering. So they are more easily bent during normal

Contour Plot of Measure -40 vs Close Angle, Open Angle
Contour plot shows at what
different settings of X’s can
achieve the target Y. It also shows
that the direction of meeting Y

47. Step 9. Implement New Process/Make Confirmation Runs
Plan to run 10pcs confirmation runs
Predict response y=-63.7694 at the optimum settings above
Compute the appropriate confidence interval of prediction based on the
number of confirmation test run.
Conduct 10 confirmation runs. Calculated average of the confirmation
runs falls within the calculated confidence interval. (Average 10
confirmation run = - 59.95)
