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

 7. Solderability

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.
