Methods for mounting a power amplifier (PA) assembly having an extended heat slug (11) are disclosed. According to one aspect, a method includes manufacturing a left side PCB (22a) and a right side PCB (22b). The method further includes sliding the left side PCB and the right side PCB inward (30) to encompass the PA assembly so that one of the left and right side PCB is in a position to contact a drain of the PA (13) and so that the other of the left and right side PCB is in a position to contact a gate of the PA (14).

In a lead mounting method of mounting, onto a principal surface (11a) of a printed board (11), a lead to be connected to a terminal, a flat lead is prepared which lead has a mounted part (21a,22a) to be disposed on the principal surface of the printed board and a connected part (21b,22b) to be connected to the terminal. The flat lead is bent into an L shape so that the mounted part and the connected part are perpendicular to each other to obtain an L-shaped lead (21,22). The mounted part of the L-shaped lead is connected and fixed onto the principal surface of the printed board by soldering. Such a method is useful for a secondary battery protection module (10).

The invention concerns a smart card, a connection arrangement and a method of producing a smart card, a semiconductor chip located on a module being inserted into a recess (24) in a card carrier so as to be connected electrically and mechanically. According to a first feature of the invention, during the milling-out of the recess, a contact bump section is exposed (22, 23) such that a reliable connection is provided between the module and induction or antenna coil (11). According to a second and third feature, the required electrical contacts are produced by soldering and the required mechanical contacts are produced by heat-sealing or fusion adhesives. Furthermore, the adhesive is provided with conductive particles and is compressed when the connection is made, such that the necessary electrical contact is brought about. According to a fourth feature, a special reinforcement frame comprising insulating sections is provided. The reinforcement frame is used to increase mechanical stability and absorb torsion forces and stresses which can occur when the card is used. At the same time, the reinforcement frame permits easy contact with strip conductors inside the card, e.g. for elements which form an antenna for contactless data-transmission.

The objective of the present invention is to obtain a press-fit terminal that can be worked readily and accurately and can reduce the contact resistance between the press-fit terminal and a through-hole, without increasing the press-fitting force when it is pressed into the through-hole and to obtain a semiconductor module provided with the press-fit terminal. The press-fit terminal is configured in such a way that there are laminated in a thickness direction (y direction) a plurality of press-fit terminal units (10 L ), each of which is made of a plate material and includes a front end portion (14) formed in the shape of a taper and press-contact portion (15) that is formed in such a way to have a pair of portions (15a) branched from the front end portion (14), and respective side faces of the pair of portions (15a) face each other through a predetermined spacing (15s), and that are inserted and press-fitted into the through-hole (31); the press-fit terminal is characterized in that respective board thicknesses (t L ) of the plurality of press-fit terminal units (10 L ) are smaller than width (Ws) of the predetermined spacing (15s) or respective widths (Wa) of the pair of portions (15a) branched from the front end portion.
