The present invention relates to a multi-folded umbrella with two layers of covers, which includes a frame with at least three-folded ribs, an upper cover and a lower cover. The method begins with coating an alignment layer on the backplane. Via communication lines and modems, the control apparatus switches on the transmission carrier of the affected satellite modem which is connected to a satellite antenna. It is determined whether the package design and the circuit design jointly satisfy: power-performance conditions specified in the acceptable power-performance envelope; and the package reliability limit based on the thermal stress considerations.
