• Application: mainly used for IC and large passive components (such as double-layer ceramic capacitor, inductor, etc.).

Production equipment: there are mainly two kinds of equipment for producing belt, one is rolling machine and the other is flat machine. The difference between the two lies in the forming of their abrasives.—PS and PC material of Carrier tape

Production materials: the materials used to produce carrier tapes are mainly PC and PS;

PC material is one of engineering plastics. PC is the abbreviation of polycarbonate, and polycarbonate is polycarbonate in English, which is referred to as PC engineering plastics.

As a material widely used in the world, PC has its own characteristics, advantages and disadvantages. PC is an amorphous thermoplastic resin with excellent comprehensive properties, with excellent electrical insulation, elongation, dimensional stability, chemical corrosion resistance, high strength, heat resistance and cold resistance; It also has the advantages of self extinguishing, flame retardant, non-toxic and colorable.

You can see the shadow of PC plastic in every corner of your life. The characteristics of large-scale industrial production and easy processing also make its price extremely low. Its strength can meet all kinds of needs from mobile phones to bulletproof glass. The disadvantage is that it has insufficient hardness compared with metal, which makes its appearance easier to scratch, but its strength and toughness are very good. –PS and PC material of Carrier tape

Whether it is heavy pressure or general wrestling, as long as you don’t try to hit it with a stone, it will live long enough.

PS English name polystyrene, chemical name polystyrene

Chemical and physical properties of polystyrene; Most commercial PS are transparent, amorphous materials. PS has very good geometric stability, thermal stability, optical transmission characteristics, electrical insulation characteristics and very small moisture absorption tendency. It can resist water and diluted inorganic acids, but can be corroded by strong oxidizing acids such as concentrated sulfuric acid, and can expand and deform in some organic solvents. The typical shrinkage is between 0.4 and 0.7%.

The lower tape of rubber packaging can be divided into PS and PC according to material, transparent and black according to color, and transparent color can be divided into insulation or antistatic. They are suitable for packaging multi-layer ceramic capacitors, resistors, inductors, etc; Black is conductive leather, which is mainly suitable for packaging transistors, diodes, ICs and any electrostatic sensitive components.

The thickness of common leather materials is generally 0.30mm, 0.35mm, 0.40mm and 0.50mm

The widths of common leather materials are generally 8mm, 12mm, 16mm, 24mm, 32mm, 44mm, 56mm, 72mm and 88mm
