A flexible circuit board equipped with type-c interface and manufacturing method thereof

Abstract

The invention discloses a flexible circuit board carrying a Type-C interface and a manufacturing method thereof. The method comprises: a first fixation hole where a fixed pin of a Type-C interface can pass is drilled and metalized at a Type-C interface zone of a flexible circuit board; a second fixation hole that has an aperture smaller than that of the first fixation hole (111) and is capable of realizing penetration of the fixation pin of the Type-C interface is drilled on a reinforced sheet made from an FR4 material, metallization processing is carried out on the second fixation hole, and forming processing is carried out on the reinforced sheet by matching the Type-C interface of the flexible circuit board; a third fixation hole having an aperture larger than that of the first fixation hole is drilled on a purity gum in a matching mode; and the reinforced sheet and the Type-C interface of the flexible circuit board are cooperatively compressed by purity gum. Therefore, carrying of a Type-C interface on a flexible circuit board is realized. Meanwhile, the production equipment is simplified; the production procedures are reduced; and the production efficiency and the yield are improved.

Description

Technical field [0001] The invention relates to the processing field of circuit boards for digital products such as mobile phones, tablets, computers, etc., in particular to a flexible circuit board equipped with a Type-C interface and a manufacturing method thereof. Background technique [0002] Type-C is a connection interface of the USB interface. It is defined by the USB Implementers Forum. It can be plugged in regardless of the front and back. The size is about 8.3mm×2.5mm. Like other interfaces, it supports USB standard charging, data transmission, and display. For output and other functions, Type-C is widely favored. In addition to its compactness, lightness, support for positive and negative insertion, and the high transmission rate of USB3.1, another important reason can support the transmission of audio and video signals. Now Type-C is widely used in electronic devices such as mobile phones, computers, PADs, etc. As the circuit boards it carries, its demand is also incr...

Problems solved by technology

At present, the Type-C interface on the board end of consumer electronic products is mostly mounted on a rigid board or a rigid-flex board. The traditional rigid board is not flexible and inconvenient to use; although the rigid-flex board has both the bearing capacity of a rigid board. And the flexibility of soft boards, but its production process is complicated, it needs to have FPC production equipment and PCB production equipment at the same time, the production is difficult, the yield rate is only about 70%, the material waste is large, the production cycle is long, and the price is expensive

Flexible circuit board is a kind of flexible printed circuit board with excellent reliability made of polyimide or polyester film as the base material. It has high wiring density, light weight, thin thickness and good bendability. characteristics, while the board of the flexible circuit board is too soft, the ability to carry electronic components is poor, and it does not have the ability to carry the Type-C interface
