Abstract:
An adhesive joint system comprises a circuit board with a distal end and a proximal end mounted on a first side via a tongue and groove connection to a housing. An adhesive is positioned at least in the gap surrounding the tongue, and an electrical component mounted to the distal end on a second side of the circuit board that is opposite the first side. The respective coefficients of thermal expansion (CTE) of the tongue, adhesive, and the material defining the groove are related, such that as heat is applied to the tongue and groove connection, the adhesive is compressed within the gap.
Abstract:
A land group (120) with which a terminal group (220) of a semiconductor package (200) has been jointed, a conductor pattern which has been arranged in a mounting area (R1) where the semiconductor package (200) was mounted and which has been jointed with a heat radiation plate (212) of the semiconductor package (200), a conductor pattern (162) at least a part of which has been arranged on the outside of the mounting area (R1), and a conductor pattern (163) which connects the conductor patterns (161, 162) are formed on a printed-wiring board (100). The land group (120) includes a land (131) adjacent to the conductor pattern (163) and a land (132) which is not adjacent to the conductor pattern (163). The land (131) is formed in a shape different from that of the land (132) so as to be away from the conductor pattern (163).
Abstract:
The present disclosure further contemplates a system and method that cools metal core printed circuit boards by circulating a liquid coolant so that it contacts the base metal of the metal core printed circuit board. In one example the present disclosure contemplates a direct liquid cooled MCPCB system that may include a liquid cavity creating component coupled to the base plate of a MCPCB allowing a liquid coolant to come into contact with the base plate of the MCPCB for cooling of the MCPCB. The direct liquid cooled MCPCB system may minimize thermal bottlenecks between the electrical components and the cooling fluid while reducing the number of components required in previous liquid cooled electronics systems.
Abstract:
Eine Leiterplatte zur Anbringung eines elektrischen Bauelements umfasst eine Oberseite und eine gegenüberliegende Unterseite, wobei ein Abschnitt der Oberseite zur Anbringung des Bauelements eingerichtet ist, ferner ein thermisches Leitelement zum Leiten von Wärme vom Bereich des Abschnitts durch die Leiterplatte, von der Oberseite zur Unterseite, eine elektrische Leitschicht an der Unterseite sowie eine elektrisch isolierende Abdeckschicht zur flächigen Abdeckung der Leitschicht. Dabei weist die Abdeckschicht im Bereich des thermischen Leitelements eine Aussparung auf.
