ESD Top Cover Tape

Heat seal type top cover tape

Heat seal type top cover tape ST-931, AS-932

ST Cover Tape (Conductive grade)

Product No.ST-931
UseShipment use of the Semiconductor,MLCC
Features• Stable peeling property can keep small chips components secure and avoid jumping problems.
• High transparency with little haze enables recognition of IC chips even after they are taped to embossed carrier tape, facilitating efficiency for quality control purposes.
• Good ESD protection prevents electrification caused by peeling and friction which may lead to electrostatic damage or jumping to semiconductor parts. Conductive polymer layer for Tape; antistatic layer for AS cover tape makes this possible.
