Product Parameters

Main reliability Indicators
Number	NAME	Performance Standard
1	Insulation Test	DC500V Under the condition of humidity 50%±5% and temperature 25ºC±5ºC, the insulation resistance is greater than 500 mω
2	Flexural Test	Make 90 bending for three times at a position 3mm away from the substrate, and the lead wire is not broken.
3	tensile Test	Hang a 1.5Kg weight under the lead wire for 30 seconds, and the lead wire will not fall off.
4	weldability Test	Use KS-C-5W flux for lead-free tin at 245ºC±5ºC; The immersion time of tin is 3 seconds, and the adhesion of new tin is over 95%
5	Pure water Test	Soak in deionized water at 25ºC±5ºC for 24 hours; There is no obvious black spot on the lead
6	Antiaging Test	At the temperature of 160ºC±5ºC, the lead wire has no obvious blackening and yellowing after baking for 2 hours
7	Adhesion Test	Two leads are intertwined or the substrate is twisted in an s shape, with a *20 magnifying glass, and the coating has no peeling and falling off
8	Air Tightness Test	The leakage rate is less than or equal to 1*10-9Pa.m3/s by helium mass spectrometer leak detector test
9	Tin Thickness Test	Thickness of lead tin layer is min2μm.
