发明名称 Apparatus for sealing a ball grid array package and circuit card interconnection
摘要 The present invention provides an electronic package assembly in which a ball grid array (BGA) is surface mounted to a printed wiring board using solder balls. Tubing is placed along the perimeter of the BGA housing to prevent subsequently applied sealant from contacting the solder balls or filling the gap between the BGA housing and the printed wiring board. This results in a seal that prevents electrical disconnection in the solder joint during operation of the electronic package assembly.
