Identifying various residues like flux (rosin-based vs. water-soluble), solder alloys, and handling oils.
✅ Identify flux type (R, RMA, WS, NC). ✅ Determine required cleanliness level (Class 1, 2, 3 per IPC-J-STD-001). ✅ Select cleaning method (aqueous, semi-aqueous, solvent). ✅ Test material compatibility. ✅ Define cleaning parameters. ✅ Verify with SIR, IC, or ROSE. ✅ Control process with statistical methods. ✅ Document and maintain records. ipc-ch-65
