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.
