The reason why introduce HASL PCB surface finish
HASL PCB circuit board metals introduce is necessary.
There were two different metals related to HASL PCB surface finish.
But many people don’t know this.
So HTD Group shared more info about metals of HASL PCB surface finish.

HASL standard surface finish typically:Tin-Lead
First is named HASL standard surface finish.
HASL standard surface finish typically metal is Tin-Lead.
This kind of HASL surface finish is normaly.
Buy the way,you may want read the definetion of Tin lead solder.
Tin/lead solders, also called soft solders, are commercially available with tin concentrations between 5% and 70% by weight.

HASL lead free surface finish typically:tin-copper,tin-copper-nickel,or tin-copper nickel germanium
Second is named HASL lead free surface finish.
HASL lead free surface finish typically are tin-copper,tin-copper-nickel,or tin-copper nickel germanium.
Now more and more people notice the environment.
and more and more electronic companies also want produce green products.
This require PCB also lead free.
So the HASL lead free surface finish is coming.
HASL lead free surface finish met ‘green’.
