    • PURPOSE:To enable to readily control the connecting shape of a solder, to provide high reliability and high workability, and to suppress the increase in the manufacturing steps by forming an isolator solder height not moistened to an insulating substrate to a semiconductor pellet. CONSTITUTION:A mounting surface of a semiconductor pellet 1 is composed to be electrically independent from a connecting electrode 2 of an independent electrode 18, and a connecting solder height 6 and an isolating solder height 19 are formd. A connecting electrode 5 and a hydrophobic film 17 are formed on an insulating substrate 4. The film 17 is formed by printing a metal material such as titanium, and a solder height 7 is formed on the electrode 5. A semiconductor pellet 1 and the substrate 4 are positioned, and heated to form a connecting solder 3 and an isolating solder 16. Since the solder 16 tends to maintain spherical shape of the prescribed size, the solder 3 and the connecting height as well as the connecting shape are controlled, and formed in a columnar or swelled shape.

    • PURPOSE:To improve the reliability by preventing the generation of whisker phenomenon and thus improving solderability by adhering fused solder or a solder material containing Sn, Pb, etc. to the external terminal of the titled device consisting of a package wherein glass is the sealing material or the component mateial. CONSTITUTION:The package of the titled device consists of a structure wherein a base 1 and a cap 2 are hermetically sealed by adhesion and fixing with the sealing glass 3 such as low melting point glass containing e.g. PbO as one of the main components. Many outer leads 4 as the external terminals project out of both sides of this package. This outer lead 4 is made of a metallic material such as an Fe-Ni series alloy whose coefficient of thermal expansion is relatively close to that of the sealing glass 3, e.g. 42 alloy. This outer lead 4 is installed to e.g. a printed circuit board by soldering at the time of mounting, and thereby the surface of said lead 4 is entirely covered with a solder coating layer 5 except for the tip surface 4a.

    • PURPOSE:To prevent the production of an improper external appearance of a semiconductor device by allowing the minimum sectional position of a pinch-off part forming a tab lead to coincide with the outside surface position of a package body, thereby reducing the exposing area of the tab lead pinch-off part to suppress the adherence of solder to the exposed surface. CONSTITUTION:The outer surface 18a of a package body 18 is disposed at the pinch-off part 17 of a tab lead 13, and the outer surface 18 is allowed to coincide with the minimum sectional position 17a. In other words, it is constructed so that the outer surface 18a of the package body 18 is contacted with the thinnest position of the tab lead 13. Thus, the tab lead 18 is cut a the pinch-off part 17, the lead 14 is cut at the frame 11, and even if it is bent or cut, the cut surface of the lead 13 which is exposed partly at the outer surface 18a becomes the minimum sectional area position, and the exposed area becomes extremely small. Accordingly, when the lead is dipped in the solder in the solder coating of later step, the solder is hardly bonded to the exposed surface of the lead 13.
    • 目的:为了防止半导体器件的外观不正确,使得形成突片引线的夹紧部分的最小截面位置与封装体的外表面位置一致,从而减少了 片状引线夹紧部分,以抑制焊料对暴露表面的粘附。 构成:包装主体18的外表面18a设置在突片引线13的夹断部分17处,允许外表面18与最小截面位置17a重合。 换句话说,其构造使得包装主体18的外表面18a与突片13的最薄的位置接触。因此,突片引线18被切断部分17,引线14是 在框架11处切割,即使弯曲或切割,部分地在外表面18a处暴露的引线13的切割表面变为最小截面积位置,并且暴露面积变得非常小。 因此,当在后续步骤的焊料涂层中将引线浸入焊料中时,焊料几乎不与引线13的暴露表面结合。

    • PURPOSE:To make it possible to plate a work of poor solderability with solder in a reliable and simple manner in a short time by degreasing the work and dipping it in a flux liquid over a long time to simultaneously remove an oxide film on the surface of the work at the time of coating the flux. CONSTITUTION:For example, the lead of a semiconductor device such as IC is degreased and dipped in a treating liquid with a flux action based on an org. acid, an inorg. salt, etc. with the strong action of removing an oxide film, e.g. zinc chloride, ammonium chloride and hydrochloric acid, and contg. little surfactant. An oxide film on the surface of the lead can be thoroughly removed by the treatment at 50-80 deg.C for 30-60sec. Even if the flux does not stick partially to the bent portion, the corner, etc. of the lead, solder is assuredly sticked and unevenness in sticking does not occur since the oxide film has been thoroughly removed. By this method a work of poor solderability or of a complex shape can be plated with solder in a reliable and simple manner in a short time.
