PV Ribbon

1. PV Ribbon Material Cu99.99% 2. Plating thickness 0.015 0.03 mm 3. Visual 1). There shall be no flows. 2). The surface shall be uniformly lustrous hue. 3). The surface shall be free from thick 4. Dimensions: Thickness: 0.10 – 0.30 mm Width : 1.5 – 10.0 mm 5. Characteristics Coating process: Hot-dip tinning Coating alloys: Sn / In / Ag / X Tensile: Extra soft, < 235 MPa Elongation: > 30 % 6.Physical Characteristic Alloy DesignationMelting Point Specific GravitySn / In / Ag / X175°C7.8g/cm3 7. Solderability ItemSpecificationTest MethodsSpread Factor　　>93%　　JIS Z3197-86 8. Recommended temperature of soldering iron tip : 280 320°C ( According to different thickness, adjust the suitable temperature of soldering ) 9. Quality The Flux should be compounded and processed in such a manner as to be uniform in quality and should be free from deleterious material and other details that will after life serviceability or appearance. 10. Visual Inspection The visual inspection is using perception to inspect the PV Ribbon Wire. The important aspect of this inspection is the coated copper must free from: 1).Whether or not there is any flaw is checked. 2).Whether or not its surface has uniform lustrous hue be inspected. 3).Whether or not its surface free from thick. 11. Coating Thickness Test The measurement to PV Ribbon Wire is using the external micrometer (0. 001mm)or its equivalents. The test piece of about 10cm long shall be taken and the OD of the wire shall be measured at 3 points.Each point shall be measured 2 times 12. Thickness Of Solder Coated Wire After the 3 points of wire be measured,dip the test piece into nitric acid for about 5 minutes,the diameter of core wire shall be measured. One half of the two measurements will give the thickness of solder coated wire.
