Hello Greg,

The HASL process is alive and well in North America.   There are many PCB shops which use both leaded (63-37) and lead free (SN100CL) HASL processes.  The shops that run HASL also offer alternative finishes like ENIG, Immersion Silver, Immersion Tin, etc.  

Unfortunately I do not have good data for the ratio of HASL use as compared to other solderable finishes.  My counterparts at Florida Cirtech can certainly provide some data.   I will forward your message to them and ask them to get in touch with you.  

Best regards,

Subject: [TN] HASL question

I'd appreciate any thoughts on the prevalence of HASL as a solder preservative.  5%? 10% of boards?

Is tin lead HASL still in use?

Is lead free HASL being used to any significant extent?

Any ideas as to the size of HASL process (tin lead or lead free) is most appreciated.

If someone has numbers or suggestions where I can get some that's great.

But estimates are welcome too.

Thanks!
