The desired distance for Flextronchip customers is 0.2 mm between two adjacent pins. Any deviation from this value causes interference. The process of handling complaints costs the firm at approximately $40.00 per chip. The engineers of the firm expect the average customer will be likely to complain when the distance is off target by at least 0.0001 mm. At the factory, the adjustment can be made at a cost of $1.60, which includes the labor to make the adjustment and additional testing.

Required:

1. What is the value of k, the cost coefficient, in the Taguchi quality loss function (QLF) based on the above data?

2. Based on a Taguchi quality loss function (QLF), what should the tolerance be before an adjustment is made at the factory?

3. Based on your answer to (requirement 2) above, what are the specification limits (upper and lower) for the production of the product in question?
