    摘要: A method for fabricating a stacked microelectronic device includes attaching a first package layer to a second package layer to form stacked microelectronic layers. Saw streets of the first package layer overlie and are aligned with saw streets of the second package layer. The first and second package layers include respective edge connectors formed between the saw streets and electronic components in the first and second package layers. A through package via is formed in one of the saw streets of the first and second package layers. The via is filled with conductive material. The stacked package layers are singulated along the saw streets in a manner that retains a portion of the conductive material to form a sidewall connector between at least two of the edge connectors.

    摘要: An electronic fabrication process and structure is provided for attaching discrete passive surface mount devices (SMD) to a substrate in a single step. A liquid noflow resin encapsulant containing flux material is dispensed between presoldered pads on a substrate. The SMD, having a pair of electrical contacts, is pressed into said encapsulant so that the electrical contacts make contact with said presoldered pads. Heat is applied to first activate said flux material and then reflow the solder on said presoldered pads to bond said SMD contacts to said presoldered pads. The reflow temperature is maintained for about 180 seconds during which time the resin solidifies. The resin encapsulant fills the space between substrate and SMD and forms fillets around the solder bonded contacts.
