Subject: [TN] White Emersion Tin?

Hello again TN’s

 

Trying to learn.

 

My question goes to White emersion tin.

1. Is it my imagination? Or does fine pitch soldering appear to be insufficient at first when you go from HASL to white tin. There for is it necessary to change the stencil thickness.
   
   
2. Are there any concerns that I should be aware of where profiling is concerned, due to a lack of HASL, the pad coverage does not seem to want to wet out away from the toe. Is this a by product of not having HASL.

 

 

 

Lastly, how does one access the archives to do research on issues that have been discussed?

 

 

 

Thanks in advance.
