Application Selection Notes for HDT (suitability for Hot-Dip Tin)

The surface of hot-dip pure tin HDT0.5-1.5μm is relatively hard, mainly to reduce the insertion force; reduce fretting corrosion, excellent softening resistance at high temperature, and not easy to flow tin and tin.

Hot pure tin HDT1-3μm has high surface hardness and low insertion force, which is the choice of conventional connectors and other products.
Hot pure tin HDT3-6μm has good corrosion resistance and significantly improves brazing performance.
Hot-dip pure tin 10-20μm different products choose coating types
