Embodiment 1）

[0077] A composite resin composition was produced, including: 40% by weight of PS-971 (Aekyung Chemical) as an unsaturated polyester; 7% by weight of tert-butyl hydroperoxide (Heiwa Pharmaceutical) as a peroxide-based curing agent 2% by weight of BYK9076 (BYK Chemie Corporation) as impregnation improver; 50% by weight of chopped glass fibers; and 1% by weight of additives.

[0078] The composite resin composition produced above was put into a metal lower mold. Later, for electronic communication devices such as image 3 As shown, a circuit board on which electronic components, positive-side terminals and negative-side terminals are formed and core blocks are bonded is stacked on the lower mold. After that, the manufactured composite resin composition was put on the circuit board, and then an upper metal mold was laminated. After allowing the mold to cure the composition at 175°C, the mold and pellets were removed. Afterwards, batteries and buttons are injected to manufactur...

Embodiment 2）

[0080] In the above-mentioned Example 1, a portable electronic communication device was produced by carrying out the same method except that a composite resin composition having the following configuration was used instead of the composite resin composition. Composite resin composition, including: 40% by weight of YD-128 (Guodu Chemical Industry) as a bisphenol A series epoxy resin; 7% by weight of phenolic resin (Guodu Chemical Industry) as a phenolic curing agent; 2% by weight as BYK9076 (BYK Chemie Corporation) impregnated with an improving agent; 50% by weight of carbon fiber; and 1% by weight of additives.

Abstract

The present invention relates to a portable electronic communication device and a manufacturing method thereof. More specifically, a portable electronic communication device includes: a circuit board which includes a battery, an electronic component operated by the battery, a positive terminal touching the anode of the battery, a negative terminal touching the cathode of the battery, and a battery accommodating part in which the battery is accommodated; and a case which covers the battery, the electronic component, the positive terminal, the negative terminal, and the surface of the circuit board, wherein the case includes a fiber filler.

Description

technical field [0001] The present invention relates to a portable electronic communication device and its operating method. More specifically, it relates to a portable electronic communication device with enhanced impact resistance and durability, and has a light weight effect, and a manufacturing method of the portable electronic communication device, which solves the problems in the conventional manufacturing method of the device including injection molding. Circuit board damage problem. Background technique [0002] Portable electronic communication devices are usually used as auxiliary devices for remote control of vehicles. The device communicates with the car, which is an external device, by electronic signals using a receiving antenna and a transmitting antenna installed inside. [0003] Portable electronic communication devices are usually dropped because of their small size, so they need to have high impact resistance and durability, and because they are used for...
