Cover tape refers to a ribbon product used in the field of electronic packaging, which is combined with a carrier tape to
Use. The cover tape is usually made of polyester or polypropylene film as the base layer and is composite or coated with different functional layers (Anti static layer, adhesive layer, etc.) can be sealed on the surface of the carrier tape under external force or heating, forming Closed space to protect electronic components in the carrier pocket.
The cover tape is mainly used in the electronic component mounting industry. It is used in conjunction with a carrier belt to integrate resistors, capacitors,
Transistors, diodes, and other electronic components are carried and stored in the pocket of the carrier belt, and the cover belt is sealed on the carrier belt to form a A closed packaging is formed above the pocket to protect electronic components from contamination during transportation Damage. During the installation of electronic components, the cover tape is peeled off, and the automatic installation device passes through the index hole of the carrier tape Precise positioning, remove the components held in the pocket in sequence, and place them on the integrated circuit board for installation On the PCB board

Pressure sensitive cover tape

cover tape

Cover tape and carrier tape must match the corresponding width in order to be used. The width of the carrier tape is different, and the cover tape is also divided into different widths. Common widths include 5.3 mm, 9.3 mm, 13.3mm, 21.3mm, 25.5 mm, 37.5mm, etc. Cover straps can be divided into two types: pressure sensitive cover straps (JSRF) and activated cover straps (JSLF).

     Pressure sensitive cover tape (JSRF), which has no adhesive at room temperature and only becomes sticky after heating, is sealed by a sealing machine by melting and pressing the hot melt adhesive of the cover tape onto the surface of the carrier tape. There are double-sided anti-static cover tapes and also single-sided anti-static cover tapes.

     

    Heat Activated Cover Tape(JSLF) has a 1.5mm adhesive layer on both edges of the cover strip, but there is no adhesive layer in the middle of the cover strip, which can be used without heating, It applies continuous pressure through a pressure roller, causing the pressure s
