Typical Printed Circuit Board Land Pattern
A typical land pattern for a circuit board is shown below. Grounding of the
metallic center pad is optional.
Case Design
All pads consist of 30 microinches (min) electroless gold on 50 microinches
(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.
