In that context, it would be a means of determining the solderability characteristics of electronic components, specificazlly components the leads or contacts of which have been pre-coated, or "tinned", with solder. Not really the sorta thing one might come across outside of highly technical references peculiar to manufacturing and/or quality control ... I'm curious - if you don't mind, could you tell me why you ask?

My friend is translating some technical articles, and he asks me this. I'm kind of know it now with your help. So thank you. But still I have to find out a expalanation in Chinese. If I have further questions. I still need your help. Thank you very much.

Timberlandko is right as you can see below :

Quote:
Testing the solderability of tin or lead-tin alloy coatings can be carried out using several different methods: dipping test, wetting balance test, globule test, solder spread test, solder meniscus measurement, and rotary dip test.

Dipping is the simplest test method to implement. The component is dipped in a flux bath and immersed vertically in a solder bath at the prescribed temperature. The criterion for acceptance is a wetting of not less than 95 per cent of the immersed surface. Non-wetted patches should be evenly distributed across the immersed area.

Francis to the rescue there - thanks Laughing - saved me some typin' - that's pretty much what I was gonna add, though said a bit more elegantly than I woulda done. Sorry, translatorcz, for not bein' specific enough the first time. Didn't know how much you wanted to know; that's why I asked why you wanted to know. I s'pose your username shoulda tipped me - my bad.
