Yes, saying you get less product because it has a larger foot print is not the same as yield loss. What I tried to say was that they were getting such poor numbers, they had to get their production numbers up through brute force of masses of equipment. They could not afford to waste numbers making tails. Today, they have better yields and my impression is that they are not at max capacity, so making suspensions with tails makes good sense. It's also another way to add value to the product. But what I don't understand is why CAPS or CIS should have any greater difficulty making tails. Perhaps I don't understand the meaning of a tail. I see it as an extension of the TSA where at the point it leaves the suspension, the stainless steel base plate is etched away, leaving the polyimid with circuits on it. All three products, TSA, CIS and CAPS have essentially the same construction, it's just the manor in which the circuits are printed. Taking the base plate away would seem to have a comparable challenge. Regards, Mark
