    • The present invention relates to a conductive contact terminal to be mounted on a substrate surface. The conductive contact terminal to be mounted on a substrate surface according to the present invention comprises: an elastic core which provides elasticity to the contact terminal; a metal layer formed to cover the outer surface of the elastic core; and a conductive adhesive layer interposed between the elastic core and the metal layer to adhere the elastic core and the metal layer together. The conductive contact terminal to be mounted on a substrate surface according to the present invention has low electric resistance, prevents materials from being deformed in a high temperature reflow soldering process, and prevents a loss of conductivity even upon the occurrence of a fracture in the metal layer that provides conductivity to the conductive contact terminal.

    • A contact plug may be wave soldered in a preferably sealed electric component, although the original core cannot be soldered, at least not with sufficient reliability. An electrically conductive contact plug (S with H or with I) for conducting current and/or voltage to/from the electric connection of a component (E) is secured by an insulator (G), for example glass (G), within a passage in a support (K), for example a protecting housing (K) of the component (E), and contains on its surface a metal capable of being soldered with a solder paint, for example soft solder, at least on the spot (on H or I) where it can be soldered to a socket (M). The socket (M) is in turn made of a metal capable of being soldered and is arranged in a support (L), for example in a printed circuit board (L) made of insulating material. The contact plug (S with H or with I) has a pin-like core (S) of a metal not capable of being soldered, at least not reliably soldered, secured by means of the insulator (G) in the passage, conductively connected (for example by a bonded wire (D) to the component (E) and surrounded by a sheath (H or I). The sheath (H or I) is in turn electroconductively secured to the core (S), for example by spot welding, and is completely made of a material capable of being soldered or has a material capable of being soldered at least on the point of its surface at which it (H or I) is soldered to the socket (M). Long-time resistant, reliable contact plug soldering, in particular for motor vehicle electronic circuits.

    • A surface mount package (60) having a plurality of exterior package leads (64) with a dual finished surface (66, 68). The lower part of the lead which is to be bonded to a bonding pad (74) of a substrate (70) such as a printed circuit board is provided with a solder-wettable surface (68) which extends only part-way up the length of the lead (64) to meet with a non-wettable surface region (66). Alternately, or in addition thereto, the upper portions of the leads (64) may be coated with a chemical, plastic or other solder- phobic composition (84) to provide the non-wettable surface region (66). Bonds made using such leads (64) are stronger and more reliable because of the affinity of the solder (72) for the lead (64) at the contact area (74) and the aversion of the solder (72) to wick up the lead into the non-wettable area (66) of the lead (64) nearer the package (60) and thus draw solder (72) away from the bonding area (74). The configuration of the solder bond is easily and quickly adjusted by controlling the area or depth of the solder coated region (68) on only the lower portion of the leads (64) of the surface mountable integrated circuit package (60).
    • 具有多个具有双重精加工表面(66,68)的外部封装引线(64)的表面安装封装(60)。 要被接合到诸如印刷电路板的基板(70)的接合焊盘(74)的引线的下部设置有焊料可润湿表面(68),其仅沿着长度方向 的引线(64)以满足不可润湿的表面区域(66)。 或者,或者除此之外,引线(64)的上部可涂覆有化学,塑料或其它阻燃组合物(84)以提供不可润湿的表面区域(66)。 由于焊料(72)在接触区域(74)处与焊料(64)的亲和性以及焊料(72)对引线的吸引力而使用这种引线(64)制成的焊接更坚固和更可靠 进入靠近封装(60)的引线(64)的不可润湿区域(66),从而将焊料(72)从结合区域(74)拉出。 通过仅控制可表面安装的集成电路封装(60)的引线(64)的下部的焊料涂覆区域(68)的面积或深度,可容易且快速地调整焊接结构。
