(1) basic ring degree of depth a need to coordinate product shell (panel the latter's back cover or side frame), can not arbitrarily change；
(1) module gross thickness b is fixed；
(2) top layer protection thickness c is limited by chip signal penetration power and the material technology of protection own limits and causes thickness to be fixed；
(4) after selected model, chip package thickness d is fixed；
(5) top layer protection maintains an equal level with basic ring top or there is little height difference, and Consumer's Experience feel can be kept without scraping good；
(6) basic ring edge thickness e limits because of technique, there is minimal design thickness.
When fingerprint modular structure stacks, basic ring degree of depth a need to be met and gross thickness b keeps constant, can only realize by adjusting basic ring edge thickness e and substrate thickness f.
