Advanced electronic technology not merely creates more multi-functional with the products of various variety,and make   them keep the miniature development trend. Modern high density technology of level is it stock productto combine , ra- ise the value of the products, however, it needs to accord with and have electromagnetic wave that various countries  make to interfere the standard to combine several pieces of digital equipment, in order toprevent it by the abnormal operation that the electromagnetic wave interferes causing. So must select to rollover the best solution . And metal conductive shielding sticky tape whether one have high electric conductioncarry metal screen of glue bring, it carry  glue and metal screen make up intact conductive body , can finish electricity join with chink cable sealing with pos- ition of sticking with metal surface any, its EMI shieldinghas the best result.
