Cover tapes is used for SMD packaging
Cover tapes is used for SMD packaging of electronic products and is often used in conjunction with embossing carrier tape.It is essentially a thin film. The 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 sensitive adhesive of the covering tape to press onto the surface of the embossings carrier tapeThere are double-sided anti-static cover tapes and also single-sided anti-static cover tapes.
Pressure Sensitive Cover Tape
JSRF is suitable for PS, PC, and ABS carrier materials, which can be repeatedly sealed. It is highly transparent and has a very stable peeling force
JSRF-03D is a single sided anti-static cover tape, with a single sided anti-static capability of up to 10 ^ 7-9 on the component bonding surface, which has the effect of eliminating static electricity
JSRF-03S is a double-sided anti-static cover tape, and the entire cover tape material is anti-static. The anti-static performance can reach 10 ^ 5-9, which has a better effect on eliminating static electricity in the product.
Heat Activated Cover Tape
JSLF-06D is a single sided anti-static cover belt, and the anti-static area of the component bonding surface can reach 10 ^ 7-9, which has the effect of eliminating static electricity
JSLF-06S is a double-sided anti-static cover tape, and the entire cover tape material is anti-static. The anti-static performance can reach 10 ^ 5-9, which has a better effect on eliminating static electricity in the product.
