Hi Jean-Francois,

It has to be analyzed. Otherwise you will never know what went wrong. 

You can contact me off line if you want to.

Subject: [TN] Poor gold plating, any solution to help soldering

Hello technetters,

 

We received a batch of PCBs that are extremely hard to solder.  The wetting
on the SMT components is fine however, the through hole is a real pain.  We
tried rubbing the pads with an eraser but no results.  

 

If the problem comes from too little gold plating, is there a solution to
help with soldering?

 

Thank you!

 

(BTW… for those who answered on the stencil issue.  I’ll send questions when
I put out some other fires!!!)

 

Jean-François
