Electrical Connections
Case Design
All pads consist of 30 microinches (min) electroless gold on 50 micro-
inches (min) electroless nickel over base metal. The metallic center pad
was designed for mechanical support. Grounding of this pad is optional.
Lid symbolization, including terminal 1 locator dot, are in contrasting ink.
Symbolization varies by model number. For purposes of illustration, only
terminal 1 dot is shown.
