| I'm looking for chemistries/recipes that will be effective
| in stripping 90/10
| tin-lead alloys off of copper leadframe devices (7025 and
| 194 Cu) that will
| leave the copper intact. I don't really care what happens
| to the plastic
| packaging. I know tin and/or tin-lead is used as an etch
| resist in the PCB
| industry, whatever chemistries are in use will probably
| work for me.
|
| Thanks in advance for your responses.
