摘要:
The present disclosure describes a closely spaced array of penetrating electrodes. In some implementations, the electrodes of the array are spaced less than 50 µm apart. The present disclosure also describes methods for manufacturing the closely spaced array of penetrating electrodes. In some implementations, each row of electrode of the array is manufactured in-plane and then coupled to other rows of electrodes to form an array.

Disclosed is a circuit comprising a first printed circuit board (2a) and a second printed circuit board (2b). The first circuit board is provided with a metal supporting board (14) and an insulating layer (8) which electrically insulates the metal supporting board on a surface, the supporting board being without any insulating layer in at least one connection region (10a-10d). The supporting board is metal-coated (12) in the connection region, and a contact (30a) of a semiconductor (30) is electrically contacted on the metal coating of the connection region. The second circuit board is provided with a metal supporting board (2b), an insulator (16) that electrically insulates the metal supporting board (24) on a surface, and a conducting layer (18) that is applied to the insulator. The insulator and the conducting layer have a breakdown region (21) in at least one contact zone, and at least one metal contact pad (20) is arranged in the contact zone in such a way that the contact pad is peripherally disposed at a distance from the insulator and from the conducting layer. The circuit boards in the circuit are separated from one another by an air gap (28) and are mechanically interconnected by at least one power semiconductor device (30).
摘要:
A printed circuit board for carrying high frequency signals. Conducting structures of the printed circuit board are shaped within breakout regions to limit impedance discontinuities in the signal paths between vias and conductive traces within the printed circuit board. Values of parameters of traces or anti-pads, for example, may be adjusted to provide a desired impedance. The specific values selected as part of designing a printed circuit board may match the impedance of the breakout region to that of the via. The parameters for which values are selected may include the trace width, thickness, spacing, length over an anti-pad or angle of exit from the breakout region.

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).
摘要:
Some example forms relate to an electronic package. The electronic package includes a first dielectric layer that includes an electrical trace formed on a surface of the first dielectric layer and a second dielectric layer on the surface of the first dielectric layer. The second dielectric layer includes an opening. The electrical trace is within the opening. The electronic package includes an electrical interconnect that fills the opening and extends above an upper surface of the second dielectric layer such that the electrically interconnect is electrically connected to the electrical trace on the first dielectric layer.

Schaltung mit einer ersten Leiterplatte (2a) und einer zweiten Leiterplatte (2b). Die erste Leiterplatte ist mit einer metallischen Trägerplatte (14) und einer die metallische Trägerplatte auf einer Oberfläche elektrisch isolierenden Isolationsschicht (8) versehen, wobei die Trägerplatte in zumindest einem Anschlussbereich (10a-10d) frei von der Isolationsschicht ist. Die Trägerplatte ist im Anschlussbereich metallisch beschichtet (12) und auf der metallischen Beschichtung des Anschlussbereichs ist ein Kontakt (30a) eines Halbleiters (30) elektrisch kontaktiert. Die zweite Leiterplatte ist mit einer metallischen Trägerplatte (2b), einen die metallische Trägerplatte (24) auf einer Oberfläche elektrisch isolierenden Isolator (16) und einer auf dem Isolator aufgebrachten Leitschicht (18) versehen. Der Isolator, sowie die Leitschicht sind in zumindest einem Kontaktbereich durchbrochen (21) un in dem Kontaktbereich ist zumindest ein metallisches Kontaktpad (20) auf der Trägerplatte derart angeordnet, dass das Kontaktpad umlaufend beabstandet dem Isolator und der Leitschicht ist. Bei der Schaltung sind die Leiterplatten voneinander durch einen Luftspalt (28) beabstandet und durch zumindest einen Leistungshalbleiter (30) mechanisch miteinander verbunden.
