摘要:
An electronic package assembly wherein a low profile package is soldered to an organic (e.g., epoxy resin) substrate (e.g., printed circuit board). The assembly's projecting conductive leads are soldered. An encapsulant material (e.g., polymer resin) is used to provide reinforcement for the solder-lead connections, the encapsulant material being dispensed only along opposing sides of the package's housing which do not include projecting leads (and which are oriented substantially normal to the stresses imposed on the package during operation wherein high temperatures are attained). This dispensing may follow solder reflow and solidification. The invention is particularly useful with thin, small outline package (TSOP) structures which occupy a minimum of height on the substrate surface.
摘要:
A removably interlockable connector assembly and process for making the assembly that include a first connector having a head on a mesa and a second connector having an opening that receives the head on the first connector. The head on the first connector and the material defining the opening in the second connector are flexible and sized, so that the head on the first connector and the material defining the opening in the second connector flex as the head on the first connector is inserted into the opening in the second connector.
摘要:
A process for making a removably interlockable connector assembly that includes a first connector having a head on a mesa and a second connector having an opening that receives the head on the first connector. The head on the mesa of the first connector and the material defining the opening in the second connector are flexible and sized, so that the head on the mesa of the first connector and the material defining the opening in the second connector flex as the head on the mesa of the first connector is inserted into the opening in the second connector. The head on the mesa of the first connector is formed by selectively etching portions of a first pad layer through openings in an etch resistant layer.
