Abstract:
An integrated circuit (IC) package (100) comprises an IC (102) and leads (104) coupled to the IC. Each lead has a first end (106) configured to be coupled to the integrated circuit and a second end (108) configured to pass through one of a plurality of mounting holes (110) extending through a mounting board (112). The leads comprise at least one positioning lead (114) comprising a stop (118) being a continuous part of the positioning lead and having a lateral dimension (120) greater than a diameter (122) of a first hole (124) of the plurality of mounting holes. The leads further comprise at least one non-positioning lead (116) having a continuous uniformly shaped body (130) with a lateral dimension (132) less than a diameter (134) of a second hole (136) of the plurality of mounting holes. The stop limits an extension of the non-positioning lead through the second hole.
Abstract:
The invention relates to a component for a printed circuit board (32) comprising a housing (10) on which at least one peg (28) is formed for engaging inside a hole (30) of the printed circuit board (32). This peg (28) has at least one detent lug (52) that projects in a radial direction with regard to the peg (28) beyond the outer periphery thereof. The detent lug (52) is placed and formed on the peg (28) in such a manner that the outer periphery of the peg (28) is smaller in the area of the detent lug (52) than the diameter of the hole (30) in the printed circuit board (32). The outer periphery of the section of the peg (28) projecting into the hole (30) in the printed circuit board (32) is formed in such a manner that, between the outer periphery of this section and the inner wall of the hole (30) in the printed circuit board (32), a space having a capillarity for solder is formed over at least a portion of the outer periphery, whereby during a soldering process, solder (50) located on the surface of the printed circuit board (32) enters, by means of capillary action, the space while filling the same.
Abstract:
An electronic component includes: an electronic component body; and a lead secured to the electric component and including a projection portion defined by first and second inclined portions facing each other. The solder wettability of the first inclined portion is smaller than the solder wettability of the second inclined portion.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of arranging and installing a socket on a board in which an ordinary printed-circuit board can be used, and which can be applied to various diameters of through holes in the printed-circuit board by the amount of sliding of the socket, and in which stable and steady contact between the conductive layer and the terminal of the socket at the inner peripheral part or peripheries of the through hole of the printed-circuit board can be obtained in a plurality of points, and the soldering work of the terminal of the socket can be eliminated, and a socket using this method. SOLUTION: The method is composed of a process of inserting a contact of a socket into a through hole of the printed-circuit board and a process of sliding the socket to the printed-circuit board. Thereby, the contact is made to contact electrically the through hole of the printed-circuit board. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
An electronic device (100) includes a printed circuit board (31) and an electronic element (50) having a terminal (52). The terminal (52) has a surface section (60) and an insertion section (59). The printed circuit board (31) includes a through hole (33) extending from a first surface to a second surface of the printed circuit board (31), a surface land (34) disposed on the first surface, and an insertion land (35) integrally disposed on a sidewall of the through hole (33) and on a periphery around the through hole (33). The surface section (60) is coupled with the surface land (34) through a solder (72). The insertion section (59) is disposed in the through hole (33) and is coupled with the insertion land (35) through the solder (72). The surface section (60) has a recess part (62) and a portion of recess part (62) is disposed so as to be axially aligned with a portion of the through hole (33).
