Careful, you may not be allowed to use it without customer approval.
You may be required to qualify such a rework process before you jump in and start changing alloys.
Introduction of other alloys does present possible reliability issues with the resultant solder joints.
If your assembly drawing states to solder with Sn63/37 or SAC305 that meets the requirements of J-STD-003 or -004 or whatever, you cannot give your customer anything except that.
And do not think that if you remove a part with it, then wick off all the solder, and solder the new part on with the required solder, you are OK. The IMC formed may not actually meet the requirements.
Just keep that in mind before you start "experimenting" on production CCAs.

Subject: [TN] Chip Quik Removal Alloy

Hi All,

Do any of you know if the Chip Quik Removal alloy (Tin 30%, Bismuth 56%, Indium 14%) works with lead-lead free solder?

We have a board here that has to have some connectors reworked that are absolutely a bear to remove and I was wondering if it works with lead-free solder?

Steve
