Abstract:
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.
Abstract:
A ball grid array device (10) utilizes solder balls (24) comprised of a core (34) having a relatively high melting temperature and a solder coating (30) having a lower melting temperature. The core (34) may be metal, a polymer or a metal-coated polymer.
Abstract:
An example device includes a lithium-based battery 100 having conductive battery contacts 206, 208 protruding from a surface 202 of the battery, where a non-conductive potion 210 of the surface of the battery separates the conductive battery contacts. The battery is a type that undergoes an expansion during charging in which the expansion of the lithium-based battery includes an outward bulging of the non-conductive portion of the battery surface. The device includes a substrate 200 having conductive substrate contacts 214, 216. The conductive battery contacts are electrically connected to the respective conductive substrate contact via a flexible electrically-conductive adhesive 600, 602 that physically separates the conductive battery contacts from the respective conductive substrate contacts and allows for relative movement therebetween caused by the expansion of the lithium-based battery.
Abstract:
FACE-UP SUBSTRATE INTEGRATION WITH SOLDER BALL CONNECTION IN SEMICONDUCTOR PACKAGE Systems and methods relate to a semiconductor package 200 comprising a first substrate or a 2D passive-on-glass (POG) structure with a passive component 204 and a first set of one or more package pads 203 formed on a face of a glass substrate 202. The semiconductor package also includes a second or laminate substrate 207 with a second set of one or more package pads 205 formed on a face of the second or laminate substrate. Solder balls 206 are dropped, configured to contact the first set of one or more package pads with the second set of one or more package pads, wherein the first substrate or the 2D POG structure is placed face-up on the face of the second or laminate substrate. A printed circuit board (PCB) 208 can be coupled to a bottom side of the second or laminate substrate.
