Abstract: An embodiment composite material for semiconductor package mount applications may include a first component including a tin-silver-copper alloy and a second component including a tin-bismuth alloy or a tin-indium alloy. The composite material may form a reflowed bonding material having a room temperature tensile strength in a range from 80 MPa to 100 MPa when subjected to a reflow process. The reflowed bonding material may include a weight fraction of bismuth that is in a range from approximately 4% to approximately 15%. The reflowed bonding material may an alloy that is solid solution strengthened by a presence of bismuth or indium that is dissolved within the reflowed bonding material or a solid solution phase that includes a minor component of bismuth dissolved within a major component of tin. In some embodiments, the reflowed bonding material may include intermetallic compounds formed as precipitates such as Ag3Sn and/or Cu6Sn5.

Abstract: A method includes depositing solder paste over first contact pads of a first package component. Spring connectors of a second package component are aligned to the solder paste. The solder paste is reflowed to electrically and physically couple the spring connectors of the second package component to the first contact pads of the first package component. A device includes a first package component and a second package component electrically and physically coupled to the first package component by way of a plurality of spring coils. Each of the plurality of spring coils extends from the first package component to the second package component.

Abstract: A method for creating partial screenshot includes displaying a screen frame on touch surface of a display unit, sensing a multi-touch gesture on the touch surface, acquiring a plurality of pixels on the screen frame according to a plurality of coordinate positions of the multi-touch gesture, defining a captured region according to the pixels, and creating a partial screenshot according to the screen frame and the captured region.

Abstract: An encrypting method of a security short message includes performing a first encryption computation according to a short message content and a deadline code to generate a verification code, performing a second encryption computation according to the short message content, deadline code and verification code to generate an encrypting field, and combining a non-encrypting field and the encrypting field to create the security short message.

Abstract: A communication apparatus and its setting method are provided. The communication apparatus has a processor and a memory device storing a short message receiving module configured to, when executed by the processor, determine whether the short message received by the communication apparatus conforms with a predetermined format. The short message includes an unencrypted prefix and multiple encrypted fields including a device serial number of the communication apparatus, a time at which the short message is sent and an operation command that controls the communication apparatus to execute a corresponding operation. The short message received by the communication apparatus is decoded to obtain the operation command when the short message conforms with the predetermined format. The operation command controls the communication apparatus to execute the corresponding operation, and the predetermined format includes at least an unencrypted field and at least an encrypted field.
