Information summary:

The reason why the carrier tape central hole can not be punched is that the burr generated by the central hole will pierce another layer of cover tape.

First, introduce the purpose of the center hole: first, the carrier belt with the center hole is determined by the shape and color of the interior parts

The main factors to consider when packaging the shield carrier tape:

1. The ratio of chip area to package area is the traveling package power, close to 1:1 as far as possible

2. The pins shall be as short as possible to reduce delay, and the distance between pins shall be as far as possible to ensure that they do not disturb each other and travel function

3. According to the requirements of heat dissipation, the thinner the package, the better. As an important part of the computer, the function of CPU directly affects the whole function of the computer. The most ferocious step in the manufacturing process of CPU is the packaging technology of CPU. There is a large distance in function when CPUs with different packaging technologies are selected. Only high-quality packaging technology is needed to consume satisfactory CPU products.

Shield carrier refers to the plastic carrier tape commonly used in the packaging of SMT electronic components such as IC, resistance, inductance, capacitor, adapter, led, fuse, switch, relay, connector, oscillator, diode and triode.

According to the purpose of the tape, the variety of the tape can be divided into: IC special tape, transistor special tape, chip LED special tape, chip inductor special tape, comprehensive SMD tape, chip capacitor special tape, SMT adapter special tape, etc; According to the material of the carrier tape, it can be divided into PS carrier tape, ABS carrier tape, pet carrier tape, PC carrier tape, hips carriertape, PE carrier tape, etc.
