본 발명은 휴대폰에 필수적으로 사용되는 안테나가 대부분 내장형으로 전환되고 있는 시기에 즈음하여 제품의 균일한 성능과 극히 높은 생산수율의 제공을 위하여 합성수지를 기재로 제조한 안테나 베이스(e)에 안테나패턴(p)의 형성재로 금속 페이스트(d)를 사용하여 스크린 인쇄기법으로 안테나 패턴(p)을 형성함으로서 높은 사출압력에 의한 안테나 소자의 변형을 원천적으로 제거하고 제품성능의 균일성과 안정성 및 100%에 근접하는 생산수율의 실현이 가능한 휴대폰용 내장형 안테나 제조방법의 제공에 관한 것이다.The present invention is an antenna pattern (e) in the antenna base (e) made of a synthetic resin base material for the purpose of providing a uniform performance and extremely high production yield of the product at the time when the antenna that is essentially used in a mobile phone is mostly converted to the built-in type By forming the antenna pattern p by the screen printing method using the metal paste (d) as the forming material of p), the deformation of the antenna element due to the high injection pressure is eliminated at the source and the uniformity and stability of the product performance and 100% The present invention relates to a method of manufacturing a built-in antenna for a mobile phone, which can realize a close production yield.
일반적으로 도 1의 A에서와 같이 휴대폰용 내장형 안테나의 제조를 위하여 0.5mm 내외의 두께를 가진 금속판재를 펀칭금형을 사용하여 가공한 안테나 소자(a)를 하부금형(h) 위에 올려놓고 도 1의 B에서와 같이 상부 금형(g)과 하부금형(h)을 결합한 후 합성수지를 기재로 하여 안테나 베이스(b)를 사출성형하는 공정으로 제조하는 것이 종래기술이었다.In general, in order to manufacture a built-in antenna for a mobile phone as shown in FIG. 1A, an antenna element (a) processed using a punching mold on a metal plate having a thickness of about 0.5 mm is placed on a lower mold (h), and FIG. As in B, it is a prior art to combine the upper mold (g) and the lower mold (h) and then to manufacture a process of injection molding the antenna base (b) based on the synthetic resin.
그러나, 이와 같은 방법으로 제조한 휴대폰용 내장형 안테나는 사출성형과정에서 안테나 소자(a)가 합성수지의 흐름에 의한 높은 압력을 받게 되어 설계사양과 다르게 변형을 일으키게 되기 때문에 제품의 균일성과 안정성이 극히 불량한 상태가 되어버리며, 이로 인하여 고주파특성의 저하와 생산수율의 저하를 초래하는 원인이 되어 내장형 안테나를 사용한 휴대폰의 신뢰성을 저하시키는 단점을 가지고 있었다.However, the built-in antenna for a mobile phone manufactured by the above method is extremely poor in uniformity and stability of the product because the antenna element (a) is subjected to high pressure due to the flow of the synthetic resin in the injection molding process and causes deformation unlike the design specification. It becomes a state, which causes a decrease in high frequency characteristics and a decrease in production yield, which has the disadvantage of lowering the reliability of the mobile phone using the built-in antenna.
본 발명은 안테나 베이스(e)에 금속 페이스트를 사용하여 스크린 인쇄기법으로 안테나패턴(p)을 형성함으로서 종래기술에서와 같이 안테나 소자(a)가 사출공정에서의 높은 압력을 받아 변형을 일으켜 휴대폰용 내장형 안테나의 고주파특성을 저하시키게 되는 현상을 원천적으로 제거한 휴대폰용 내장형 안테나의 제조방법을 제공하는 것이다.The present invention forms the antenna pattern (p) by a screen printing method using a metal paste on the antenna base (e), as in the prior art, the antenna element (a) is subjected to a high pressure in the injection process, causing deformation and thus for a mobile phone It is to provide a method of manufacturing a built-in antenna for a mobile phone that eliminates the phenomenon that the high-frequency characteristics of the built-in antenna is reduced.
따라서 본 발명의 목적은 종래기술에서와 같이 휴대폰에 사용하기 위한 내장형 안테나를 제조하기 위하여 단순히 얇은 금속판재를 펀칭금형으로 가공하여 제조한 안테나 소자(a)를 합성수지와 함께 높은 사출압력에 의한 안테나 소자(a)의 변형을 감수하고 사출성형하는 방식에서 탈피하여, 도 2의 A에서와 같이 안테나 베이스(e)에 인쇄 스크린(b)을 접촉시킨 후 스크린 인쇄용 주걱(c)으로 밀어 금속 페이스트(d)로 안테나패턴(p)를 인쇄함으로서 높은 사출압력에 의한 안테나 소자(a)의 변형을 원천적으로 제거한 휴대폰용 내장형 안테나를 제조할 수 있도록 하는 것이다. Therefore, an object of the present invention is to produce an antenna for use in a mobile phone as in the prior art antenna element (a) produced by simply processing a thin metal plate into a punching mold with a synthetic resin antenna element by a high injection pressure Breaking away from the modification of (a) and injection molding, as shown in A of FIG. 2, the printing screen (b) is brought into contact with the antenna base (e) and then pushed with a spatula (c) for screen printing to paste the metal paste (d By printing the antenna pattern (p) to be able to manufacture a built-in antenna for a mobile phone by removing the deformation of the antenna element (a) due to a high injection pressure.
이 과제는 도 2의 A에서와 같이 안테나 베이스(e)에 금속 페이스트(d)로 안테나패턴(p)을 스크린 인쇄함으로서 간단히 달성할 수 있다.This problem can be easily achieved by screen printing the antenna pattern p with the metal paste d on the antenna base e as in FIG.
본 발명은 통전성이 있는 안테나 패턴(p)의 형성재로 금속페이스트인 실버 페이스트, 혹은 동 페이스트를 사용하며 안테나 패턴(p)과 안테나 단자(r)의 접속은 실버페이스트를 사용한다. .In the present invention, silver paste or copper paste, which is a metal paste, is used as a material for forming the electrically conductive antenna pattern p, and a silver paste is used for the connection of the antenna pattern p and the antenna terminal r. .
또한, 본 발명은 안테나 베이스(e)의 기재로 폴리카보네이트와 같은 경도와 인장강도가 높은 합성수지를 사용하며, 이는 물리적 특성이 휴대폰용 내장형 안테나의 성능유지에 유리하기 때문이다.In addition, the present invention uses a synthetic resin of high hardness and tensile strength, such as polycarbonate as the base of the antenna base (e), because the physical properties are advantageous for maintaining the performance of the built-in antenna for mobile phones.
본 발명의 안테나 패턴(p)에 대한 단자 처리는 도 3의 A에서와 같이 안테나 베이스(e)에 안테나단자 홀더(s)를 접착하고 안테나패턴(p)와 안테나단자(r)를 실버 페이스트로 접속한다.Terminal processing for the antenna pattern (p) of the present invention is to adhere the antenna terminal holder (s) to the antenna base (e) as shown in Figure 3A and the antenna pattern (p) and the antenna terminal (r) with silver paste Connect.
본 발명은 실버 페이스트와 동 페이스트는 섭씨 75도 이하에서 경화되면서 금속을 양생하는 것이거나, 자외선의 조사로 경화되면서 금속을 양생하는 것을 사용한다. 이는 높은 열에서 경화되고 금속을 양생하는 것은 안테나 베이스(e)를 변형시키는 원인이 되기 때문이다.In the present invention, the silver paste and the copper paste are used to cure the metal while curing at 75 degrees Celsius or less, or to cure the metal while curing by irradiation of ultraviolet rays. This is because curing at high heat and curing metal cause deformation of the antenna base (e).
이상 설명한 대로, 본 발명의 휴대폰용 내장형 안테나의 제조방법으로 제조된 휴대용 내장형 안테나는 어떤 물리적 힘을 받지 않고 제조되기 때문에 종래기술에서와 같이 안테나 소자(a)의 변형에 의한 고주파특성의 열화현상, 제품의 균일성 및 안정성의 저하, 생산수율의 저하와 같은 부정적 요인들을 완벽하게 제거할 수 있게 되어 휴대폰의 제조에 있어 높은 성력화의 실현을 가능하게 할 수 있을 것이며, 현재 휴대폰 제조업체에서 수입하고 있는 휴대폰용 내장형 안테나를 국산으로 대체함으로서 많은 외화의 절약이 가능하도록 할 것이다.As described above, since the portable built-in antenna manufactured by the method of manufacturing the built-in antenna for a mobile phone of the present invention is manufactured without receiving any physical force, deterioration of high frequency characteristics due to deformation of the antenna element (a), as in the prior art, It will be possible to completely eliminate the negative factors such as the decrease in the uniformity and stability of the product and the decrease in the production yield, which will enable the realization of high performance in the manufacture of mobile phones. It will be possible to save a lot of foreign currency by replacing the built-in antenna for domestic.
또한, 본 발명에 의한 휴대폰용 내장형 안테나 제조방법과 동일하거나 유사한 것이 없기 때문에 우리나라를 휴대폰용 내장형 안테나의 종주국으로 부상하게 할 것이다.In addition, because there is no same or similar to the method for manufacturing a built-in antenna for a mobile phone according to the present invention will make Korea emerge as a slave country of the built-in antenna for a mobile phone.
