In the present invention, the present invention relates to a method of manufacturing a connector connection terminal formed on an end portion of a wiring board, and in particular, it can be manufactured at a lower cost and is fitted to a ZIF. A method of connecting a connector such as a connector or a press-in connector. [Prior Art] [0002] Based on the reason that the contact resistance with the connector can be reduced, the wear of the terminal, the wear of the body, and the emulsification of the metal material for forming the terminal are prevented, etc., most of the connections are usually made at the connector: : A conductive film is formed on the film. Further, the conductive film system is required to have the following characteristics, that is, the film 1 which is not peeled off from the metal material, is thin, and is not etched by oxidation. [0003] You used to be Ϊ ‘from the cheap point of view, most of the use of the surface of copper: there are methods of eutectic _ electricity money, but from today's environment pollution "" conductive skin. In the case of a conductive film that satisfies the characteristics described above, gold or gold is used as gold ore, and then gold is applied as gold. However, since two different films are required to make the treatment troublesome, although it is cheaper than the cost of the gold-plated monomer, it is still expensive. Although it replaces gold plating and converts it into pure tin or tin-based alloy (so-called lead-free solder), in this case, tin whiskers are easily generated, and leakage current or short circuit occurs. [0004] ▲ In addition, a wiring board in which a thin resin film layer is formed in advance on a plated portion of a pure tin or tin-based alloy to prevent the occurrence of whiskers is also known (for example, 'Reference Patent Document 1). [Problem to be Solved by the Invention] [0005] The invention described in Patent Document 1 is formed by the formation of an electric ore portion of a pure tin or tin-based alloy. Resin film layer to prevent environmental problems caused by lead and metal whiskers. On the other hand, when the connector is inserted, the resin film is electrically contacted by frictional damage, and the position of the resin film layer is soft. It has a problem of so-called lack of stability and reliability in the case of multiple insertion and removal or long-term use. Although the gold plating is excellent in terms of stability and reliability, the 1323960 is expensive as described above, and it is required to have two different films of the solder film and the resin film on the wiring substrate, which is troublesome in handling. 【0007】

若是在銅端子的表面印刷無敍的銲料膏以形 成銲料層的方法,則難以產生錫的金屬鬚而且廉 價,但是銲料膏容易因熔化而在厚度上產生不均 一。又’利用銲料膏形成的銲料層係變得比電鍍皮 膜還厚。而從連接器的共用化觀點,有必要成為與 電鍍皮膜的端子厚度相同的方式來形成銲料層,但 是當要將銲料膏的厚度印薄時,在熔化時,因為銲 料會熔化擴散而產生不均,故,以往要形成薄且厚 度均一之銲料層是很困難的。 【0008】 於是,本發明之目的在於提供一種連接器接續 用端子的製造方法,係於連#器接續用$子上印刷If a solder paste is printed on the surface of a copper terminal to form a solder layer, it is difficult to produce tin whisker and it is inexpensive, but the solder paste is liable to be uneven in thickness due to melting. Further, the solder layer formed by the solder paste is thicker than the plating film. From the viewpoint of the sharing of the connector, it is necessary to form the solder layer in the same manner as the thickness of the terminal of the plating film. However, when the thickness of the solder paste is to be thinned, the solder melts and spreads during melting. Therefore, it has been difficult to form a thin and uniform solder layer in the past. Accordingly, it is an object of the present invention to provide a method for manufacturing a connector connection terminal, which is to be printed on a connected device.

When the solder paste is printed on the surface of the connector end and melted, the molten solder flows out in a wide area of the joint region, so that the thickness of the solder layer in the region becomes thicker and the connector is connected. In the part of =, the material layer (4) becomes thin and the thick end of the material is smeared. The extension is cut off and the connector is connected - the two are formed into a predetermined length. ^ [Effect of the Invention] [ooli] and the second barren are used to extend the terminal portion of the terminal for connector connection and to provide a wide connection area, and to melt the molten solder when the solder paste is melted. By extending the thickness of the solder layer of the terminal portion to: :::: This can form the (four) solder layer with the same thickness as the terminal of the plating film and has a uniform thickness, and can prevent the ring 8 1323960 * Dyeing and metal whiskers occur to reduce costs. [Embodiment of the Invention] [Embodiment of the Invention] [0012] Hereinafter, a method for manufacturing a connector connection terminal of a wiring board according to the present invention will be appropriately described. For example, let me explain. In order to achieve the purpose of providing a solder layer which is capable of printing a lead-free solder paste on a connector connection terminal, the thickness of the solder layer is formed into a thin and uniform connector terminal I. The present invention is achieved in such a manner that the terminal portion of the connector connecting terminal formed by the plurality of contact pieces provided on the wiring substrate is extended longer than a predetermined length, and is provided to be used for a connection region in which the extension portions are connected to each other, a solder paste is printed on the surface of the connection terminal for the connection f including the connection region, and the solder paste which is printed is melted to form a solder pre-coat layer, and then the foregoing The extended portion of the continuous region is cut and removed to form a predetermined length. [Embodiment 1] [0013] Fig. 1 shows a printed wiring board 1 〇, which is attached to an insulating substrate]! The surface of the conductor is provided with a conductor such as copper foil. Then, a portion of the conductor 9 1323 960 is removed by etching to form a wiring pattern 12, which is shielded by a cover layer 13. On the other hand, the connector connecting terminal 2 composed of a plurality of contact pieces 14 is exposed from one end of the opening portion 15 of the protective layer to form a predetermined length L indicated by a chain line. The connector connection terminal 2 is formed to be wider than the other wiring patterns 12. [0014]

連接器接續用端子2〇之終端部被延長超過前 述既定長度L,此延長部分2】也可被收納於保護 層之開口部15内,圖示例中,延長部分2】係超過 開口部15的他端而被形成在保護層13的下面。此 外,設置有將此延長部分2丨彼此間予以接續用的 連結區域22。 【0015】 圖2顯示既於前述印刷配線基板1 〇之保護層 的開口部15印刷銲料膏16之後的狀態,銲料^ 16·不僅是對連接器接續用端子2〇之既定長度[的 部分,而是對接觸片】4之相互間以及包含有連結 區域22.的延長部分21全體一起進行印刷。 【0016】 圖3顯示熔化後的狀態,導電體以外的部分之 銲料膏16被加熱熔融而流入導電體的表面〔二 冷卻硬化之後形成銲料預塗層17。通常, 塗層〗7係於導電趙的表面全體上形成均一的= 10 1323960 • . 度’如同圖示般’含有前述連結區域22的延長部 分21之面積因為比連接器接續用端子2〇的接觸^ 14之面積還大,所以既形成於含有連結區域22的 延長部分21上的銲料預塗層17之厚度變厚,而連 接器接續用端子20的接觸片14上形成厚度薄且為 均一厚度之銲料預塗層17。 【00]7】The terminal portion of the connector connection terminal 2 is extended beyond the predetermined length L, and the extension portion 2 can be housed in the opening 15 of the protective layer. In the illustrated example, the extension portion 2 exceeds the opening portion 15 The other end is formed under the protective layer 13. Further, a connecting region 22 for connecting the extended portions 2 to each other is provided. [0015] FIG. 2 shows a state after the solder paste 16 is printed on the opening 15 of the protective layer of the printed wiring board 1A, and the solder is not only a predetermined length of the connector terminal 2; Instead, the contact sheets 4 are printed together with each other and the entire extension 21 including the connection region 22. Fig. 3 shows a state after melting, in which a portion of the solder paste 16 other than the conductor is heated and melted to flow into the surface of the conductor (two types of solder precoat layer 17 are formed after cooling hardening). In general, the coating layer 7 forms a uniform on the entire surface of the conductive film = 10 1323960. The degree 'as shown in the figure' contains the area of the extension portion 21 of the aforementioned joint region 22 because it is larger than the terminal 2 of the connector. Since the area of the contact 14 is large, the thickness of the solder precoat layer 17 formed on the extended portion 21 including the connection region 22 is thickened, and the contact piece 14 of the connector connection terminal 20 is formed to be thin and uniform. A solder pre-coating of thickness 17. [00] 7]

在以往,就算是想薄薄地印刷銲料膏以形成薄 的銲料預塗層,也會因為銲料熔化擴散而產生不 均,無法形成均一厚度之銲料預塗層,但是如同上 述那樣,藉由事先形成包含有大面積的連結區域 22之延長部分2卜可在連接器接續用端子20的接 觸片14上形成薄且均一厚度的預塗層17。 【0018】In the past, even if it is intended to print a solder paste thinly to form a thin solder pre-coat layer, unevenness may occur due to melting and diffusion of the solder, and a solder precoat layer having a uniform thickness cannot be formed, but as described above, by forming in advance The extension portion 2 including the large-area connection region 22 can form a thin and uniform thickness of the precoat layer 17 on the contact piece 14 of the connector connection terminal 20.
