Plated
1. The plating of the conductor is smooth and continuous on the surface ,And should not be any defects that affect the product performance
2.The plating of the conductor is continuous , after Na2Sn test ,it shall not be black .Or after the test of (NH4)2SO4 , t he salt liquid is not deep in color than the standard color of the liquid color
Testing
1. All products must be tested qualified before delivery,the quality certification report should be delivered together with each batch..
2. Products testing rule is as follows :
NO Item Testing method |
1 Tin percentage &Plated Thickness Plated Thickness Tester |
2 Diameter of single wire and tolerance Micromrter in micro |
3 Appearance Normal Visual Test |
4 Continuity of testing GB/T4909.910 |
5 Machine Capacity GB4910-1985 |
6 Resistivity GB4910-1985 |
7 Solderability |
