Solder Alloy:SN100C、Sn-3.0Ag-0.5Cu

Evaluation of Wettability and Spreadability with Stranded Wire Used for Speaker

SN100C
Wets and Spreads Faster than SAC305!

SN100C(MP: 227℃)provides
superior wettability and spreadability
to SAC305(MP: 218-219℃), as it wets
and spreads over the stranded wire faster.

〔Test Conditions〕
・Equipment Digital Hot Plate
   
Digital Microscope
・Hot Plate Temperature 350℃
〔Test Method〕
  • Place stranded wire on a 50×50mm ceramic plate.
  • Set flux-cored solder wire samples over the stranded wire.
  • Place ceramic plate containing stranded wire and flux-cored solder wire samples on a hot plate.  Video the process of wetting and spreading of flux-cored solder wires onto the stranded wire with digital microscope.
