The one in-charge on this issue is Surasak Chimma, which uses surasak.c@hongseng.com as his email. I'm a bit confuse that how Alvin got surasak.s@hongseng.com on this subject because I don't think Surasak Sifueang would know about this issue.
By this way, I already passed this subject to Surasak Chimma and talked with him by phone. He will answer back to Alvin by today.
