Abstract:
A method is for making a non-planar three-dimensional (3D) multilayered circuit board. The method may include forming a stacked arrangement including at least one pair of liquid crystal polymer (LCP) layers with a bonding layer therebetween. The stacked arrangement may further include at least one electrically conductive pattern layer on at least one of the LCP layers. The method may further include heating and applying pressure to the stacked arrangement to shape the stacked arrangement into a non-planar 3D shape and concurrently causing the bonding layer to bond together the adjacent LCP layers of the stacked arrangement to thereby form the non-planar 3D multi-layered circuit board.
Abstract:
Die Erfindung beschreibt eine Kontaktanordnung zur Kontaktierung eines Kontaktstiftes, wobei als Kontaktelement zwei sich gegenüberstehende Reihen von Kontaktzungen verwendet werden. Die Kontaktzungen einer Reihe erstrecken sich bis in Zwischenräume von Kontaktzungen der gegenüberliegenden Reihe. Durch die Verwendung von Kontaktzungen, die sich über eine Mittenachse des Kontaktelementes erstrecken, ist eine elektrische Kontaktierung eines Kontaktstiftes mit guter Leitfähigkeit möglich, obwohl dessen Position seitlich aus der Mittenachse verschoben ist. Vorzugsweise stehen sich Reihen von unterschiedlich langen Kontaktzungen gegenüber, wobei einer kurzen Kontaktzunge einer ersten Reihe eine lange Kontaktzunge einer zweiten Reihe zugeordnet ist. Vorzugsweise sind zwei identisch aufgebaute Kontaktelemente übereinander angeordnet, wobei jeweils eine lange und eine kurze Kontaktzunge übereinander angeordnet sind. Die kurzen Kontaktzungen dienen zur Erhöhung der Anpresskraft der langen Kontaktzungen. Auf diese Weise kann eine verbesserte elektrische Kontaktierung von Kontaktstiften mit einer flexiblen Leiterplatte, insbesondere von elektrischen Relais mit einer flexiblen Leiterplatte erreicht werden.
Abstract:
A printing surface includes a substrate (10) having latching electrodes (14a, 14b) on a first surface, a spacer layer on the first surface of the substrate, the spacer layer (24) patterned to form wells such that the latching electrodes reside in the wells, a deformable membrane (18), the membrane having conductive regions, on the spacer layer (24) to enclose the wells, each enclosed well and its associated region of the membrane forming a pixel membrane, and actuation circuitry to actuate the electrodes to cause selected ones of the pixel membranes to remain in a deflected state when the pixel membranes receive an impulse to return to an undeflected state.
Abstract:
A conductive portion is formed in a hole formed in a material sheet. A metal foil is placed on a surface of the material sheet to provide a laminated sheet. The laminated sheet is heated and pressed to provide a circuit-forming board. The metal foil includes a pressure absorption portion and a hard portion adjacent to the pressure absorption portion. The pressure absorption portion has a thickness changing according to a pressure applied thereto. The circuit-forming board provided by this method provides a high-density circuit board of high quality having reliable electrical connection.
