Dear Technetters,
I have some BGAs which have the following comments in the Mechanical
Requirements section:
Leadframe Plating: Copper base material with a 5-micron (200 micro-inches)
minimum of Tin/Lead overplating containing 10-40% lead.
Can one of the Enlightened Ones please help someone groping in the darkness?
As always, I appreciate the feedback I receive.
