This test performed in accordance with MIL-STD-202, Method 208 and resistance to solder heat per MIL-STD-202, Method 210,Test Condition C.
The terminals are exposed to a solder bath of 350o F, at an immersion angle of 90o. The devices are then held in the solder bath for a period of five (5) to ten (10) seconds. The solder is applied to either ¼ inch from the nearest insulating material of the component or ½ of the exposed length of the terminal (which ever is closer). This test verifies that pre-assembly lead finish provides a solderable surface and sufficient quality to make an acceptable solder joint.
By passing, it proves that the device can withstand the heat applied during the solder operation.
