（１） The protection component has the functions of anti-static, anti-magnetic wave, moisture-proof, dust-proof, friction free, vibration reduction, turnover and ejection, while maintaining its original functions and characteristics.

(2) because of its design, the dimensions of carrier tape must meet the specifications .Only within the allowable range can the bearing elements be positioned to ensure.  Taping and SMT operation processes on the server can access the correct efficiency.–function of designing carrier tape

Design Essentials: the carrier tape is designed according to the provisions of the international standard EIA, and the relevant matters needing attention are as follows:

（１）       Select the control of surface characteristics: such as surface impedance, brightness, physical properties, strength, etc.—function of designing carrier tape

（２）       According to the size and thickness of the component, when forming the carrier, the width and thickness of the sheet are selected.

（３）       Matching matters of cover tape: such as cover tape width, sealing width, sealing position, peel force strength and aging test.

（４）       Individual and cumulative tolerances of pitch.
