Wire-bonding is more or less on schedule. Full ladder assembly is somewhat behind due to a problem of biasing scheme for burn-in. They still expect to meet the schedule. He presented new scheme based on kapton hybrid, TPG substrate and butt-joint. Flex circuit also solve the problem.
Further investigation is necessary.
Yamada presented possible detector layouts for SVD2 using the DSSD size proposed by Tajima. There was suggestion to avoid wind-mill structure which is not CP friendly. Examples of support structure from BaBar and CLEO3 are also shown. Support structure for the SVD2 will be finalized by the next meeting. There are two types, one for the innermost layer and the other for the rest.
