By leaded/non-leaded are you speaking of LGA arrays (leadless gate
arrays) or of BGAs with SAC alloy?

Subject: [TN] Leaded and unleaded BGAs

Technetters,

Question for the process folks.............

We have leaded BGAs that we could use and still maintain 5/6 RoHS
compliance.

Does anyone have a process for attaching leaded and nonleaded
components?

Using SRT for the leaded parts or even reballing them with nonlead?

Is there an acceptable method for doing this or are they E & O
candidates?

Any info appreciated................DJT
