Abstract:
An elastic printed board (102) is provided so that stress applied by the silicon gel (101) is absorbed by the printed board (102). Further, the printed board (102) is formed to be so narrow that the stress may be escaped. On the other hand, the wires on which a high voltage is applied are patterned on respective printed boards. This serves to prevent discharge through the surface of the same printed board served as current passage. This design makes it possible to hermetically close the power module, prevent intrusion of moisture or contamination as well as displacement, transformation and crack of the cover plate (105).

Abstract:
When the ceramic substrate of a ceramic column grid array is connected with a large number of columns, a mounting jig is arranged on the ceramic substrate and a column is inserted into the hole of the mounting jig. When the columns are inserted one by one into the holes of the mounting jig, the productivity is low and the cost increases. A column suction head enables the columns to be inserted into all holes of the mounting jig at a time. Elongated holes are bored in the body at the same positions as those of the electrodes provided on the ceramic substrate of the ceramic column grid array and a suction hole is bored in the bottom of each elongated hole. When a column suction head is set on an arranging jig where the columns are arranged and air is sucked through the suction holes, the columns of the arranging jig are sucked into the elongated holes of the column suction head.

The invention relates to an electrical connection element (9) between a contact area (10) and an electric feeder (6, 7), especially in an electric switch for an electric tool such as a battery-powered tool, said electric switch being provided with an electronic control circuit (8). The connection element (9) comprises at least one metal pin (11) and a fixing element (12) made of an electrically non-conducting material. The pin (11) is fastened within the fixing element (12) such that the pin (11) is aligned with the associated contact area (10) and the feeder (6, 7) while both ends thereof protrude from the fixing element (12) in order to contact the contact area (10) and the feeder (6, 7), optionally as in SMD (surface mounted device) technology.
Abstract:
[Problem to be Solved] When a multiplicity of columns are to be connected to a ceramic-substrate of a ceramic column grid array, a mounting jig is placed over the ceramic substrate, and the columns are inserted into holes of the mounting jig. If the columns are inserted into the holes of the mounting jig one by one, productivity is degraded, and the production cost increases. The present invention is a column suction-holding head capable of inserting columns into all the holes of the mounting jig collectively at once. [Solution Means] The body of the column suction-holding head has elongate holes at the same positions as those of electrodes installed on a ceramic substrate of a ceramic column grid array, and suction holes are provided at the bottoms of the elongate holes. The column suction-holding head is superimposed on an alignment jig having columns aligned therein, and suction is applied from the suction holes. Consequently, the columns in the alignment jig are sucked into the elongate holes of the column suction-holding head.
