Hi Ioan! You can assess the solderability of a HASL surface finish using 
the IPC-JSTD-003 specification. The thickness of a surface finish has a 
direct impact on the solderability and shelf life characteristics. The 
JSTD-003 specification covers how to do the solderability testing. The 
thickness requirement for a HASL surface finish would be in IPC-6012 or 
per your internal requirements.

Subject
[TN] PCB Solderability issues






Dear Technos,

 

The PCB HASL wetting issues saga is not over. The PCB fab told me they are 
doing XRF on the pads. Does this have anything in common with 
solderability assessment?

 

What would be the methods of measuring solderability of HASL bare boards? 
And what are the pass limits?

 

Thank you,
