    Abstract: The invention discloses a method for transmitting digital contents between devices. First digital contents are modulated into an audio signal in a first device, wherein the first digital contents include contact information and at least one index of at least one second digital content. The audio signal is outputted by at least one audio generator of the first device and then received by at least one audio receiver of a second device. The audio signal is demodulated in the second device to make the second device obtain the first digital contents. The second device obtains the at least one second digital content according to the at least one index of the at least one second digital contents through a wired or wireless communication.

    Abstract: A process of manufacturing thin ball array substrates includes the steps of: using a layer of polyimide film as a carrier, electroplating a thin copper layer on the polyimide film, electroplating a thick copper layer on the thin copper layer, applying photosensitive coating layers on both sides of the carrier, mounting two masks with optically transmissible circuit tracks on two sides of the carrier and then processing the carrier with exposure treatment, processing the carrier with development treatment so as to remove the photosensitive coating layers aligned with the circuit track thereby forming recessed circuit tracks on the photosensitive coating layers, electroplating a copper layer on a top of the carrier thereby forming an additional copper layer on the thick copper layer, etching a bottom of the carrier to remove the upper recessed circuit track thereon, coating the copper layer on the upper recessed circuit track with soldering metallic material so as to make a top of the soldering metallic material, washing away the photosensitive coating layers with chemical agent, and removing surplus copper layer to remain in circuit lines and the soldering metallic material, whereby a thin ball grid array substrate with thicker circuit lines without remaining electroplating lines can be obtained.
