Problems solved by technology

[0006] The carrier tape material prepared by the above invention patents and known technologies, the surface layer uses PS conductive masterbatch, and the middle layer uses ABPS (acrylonitrile-butadiene-styrene). Since the nitrile group is hydrophilic, the carrier tape can be used during thermoforming. If it is not dried, it is easy to form pits on the surface of the carrier material, resulting in scrapped products, not only easy to break, but also easy to cause device damage

Abstract

Belonging to the field of material preparation, the invention specifically relates to a moisture-proof and high strength IC carrier tape material. The material is characterized by adopting the technical scheme of: mixing 55-75 parts of polystyrene, 5-15 parts of high density polyethylene, 15-30 parts of organosilicon grafted polyethylene polypropylene, 2-8 parts of an aging-resistant linear triblock copolymer, 1-5 parts of a toughening agent, and 0.3-0.8 part of an antioxidant evenly, then conducting granulation by a twin-screw extruder to obtain a granulated material, and then mixing the granulated material with 3%-5% of black masterbatch and conducting extrusion, thus obtaining the carrier tape material.

Description

technical field [0001] The invention belongs to the field of material preparation; in particular, it relates to a moisture-proof high-strength IC carrier tape material. Background technique [0002] Carrier tape refers to a strip-shaped product used in the field of electronic packaging. It has a specific thickness, and holes (also known as pockets) for holding electronic components are equidistantly distributed along its length direction and are used for indexing. positioning holes. It is widely used as a plastic carrier for the packaging of SMT electronic components such as IC, resistors, inductors, capacitors, connectors, LEDs, fuses, switches, relays, connectors, oscillators, diodes, and triodes. [0003] CN101475721B discloses an antistatic plastic used for SMT carrier tape, a preparation method thereof, and a composite plastic sheet prepared by using the above antistatic plastic. Antistatic plastic used for SMT carrier tape, the antistatic plastic is composed of the f...
