Material strap of large size surface for mounting component with structure increasing part

Abstract

The invention relates to a carrier tape which is used for superficial installation components, in particular discloses a large-size carrier tape that is provided with structure strengthening parts and is used for superficial installation componens . The carrier tape consists of a lengthwise tape body, a surface tape and the structure strengthening parts. Plural holding chambers are formed lengthways along the tape body, and a predetermined clearance is arranged between every holding chamber and the adjacent holding chambers. The surface tape is attached on the lengthwise tape body in a detachable way and can be used for sealing all the holding chambers. Corresponding to each holding chamber and far away from each clearance, the plural structure strengthening parts are formed on the lengthwise tape body and extend along the length. Matching with automated superficial installation exercise equipment, the invention can be used for surely preventing a large superficially installed component such as an electromagnetic wave protecting cover and the like from damaging caused by bending and deformation during the storing and carrying process, and worthless wearing and tearing can be reduced effectively, thereby lowering the cost.

Description

technical field [0001] The invention relates to a material tape for surface mounting components, in particular to a material tape for large-size surface mounting components. Background technique [0002] It is often necessary to set various circuit components on the circuit board. In order to quickly fix the semiconductor components and other circuit components to the correct predetermined position on the circuit board, most of them currently use robotic arms to automatically pick up and move the circuit components to the circuit board. Do most of the welding assembly work. [0003] However, the circuit components on some circuit boards will interfere with the operation of other adjacent circuit components due to the emission of electromagnetic waves. Especially in mobile communication devices in the field of wireless communications, the antenna must emit electromagnetic waves to communicate with the base station. The normal operation of other circuit components poses a thr...

Problems solved by technology

[0006] The deformation of the large-sized components included in the material belt 5 not only increases the defective rate of the product and significantly increases the cost, but a bigger problem often occurs in case a fish that is not seriously bent and slips through the net is mistakenly released and enters the production line. However, due to a little bending, the shielding effect cannot be fully achieved, resulting in a shielding gap, and the electromagnetic wave completely penetrates through the welding gap.

Conversely, in order to avoid such inferior products, manufacturers using large-size components must carefully inspect each large-size component in detail, resulting in a heavy burden on quality management
