Dielectric material change to optimize electrical and mechanical properties of flex circuit

Номер: GB2616810A
Автор: Busby James, Clifford Long David, Doyle Matthew, Fisher Michael, J Higby Arthur, K Buchling Rego Philipp, N Cohen Edward, R Dangler John, Santiago-Fernandez William
Принадлежит: International Business Machines Corp

A uniform thickness flex circuit is taught that uses more than one dielectric layer. A first dielectric layer is more flexible and capable of reliably bending at a radius of curvature at which a second dielectric layer cannot be reliably bent. The second dielectric layer has at least one more desirable electrical characteristic than the first dielectric area, for example leakage. Use of the uniform thickness flex circuit to protect sensitive material in an electronic enclosure is also described.

Es wird eine flexible Schaltung mit gleichmäßiger Dicke gelehrt, die mehr als eine dielektrische Schicht verwendet. Eine erste dielektrische Schicht ist flexibler und in der Lage, sich mit einem Krümmungsradius zuverlässig zu biegen, mit dem eine zweite dielektrische Schicht nicht zuverlässig gebogen werden kann. Die zweite dielektrische Schicht hat mindestens eine wünschenswertere elektrische Eigenschaft als die erste dielektrische Schicht, beispielsweise in Bezug auf den Leckverlust. Ebenfalls beschrieben wird die Verwendung der flexiblen Schaltung gleichmäßiger Dicke, um sensibles Material in einem Elektronikgehäuse zu schützen.
