摘要:
A low thermal impedance printed circuit board assembly compatible with surface mount assembly reflow solder processes is presented. The low thermal impedance printed circuit board assembly may have filled vias soldered directly to solder balls of the surface mount assembly.
摘要:
An epoxy filled via hole in a printed circuit board is presented. The epoxy filled via hole may have metal plating between the epoxy and the via hole walls of the printed circuit board. The epoxy filled via hole may have a land pad directly over the epoxy filling, creating a compact contact area for an ATE interposer.
