Solder Surfaces for Printed Circuit Boards, Part 4: HAL lead-free
The HAL lead-free solder surface offers the best solderability of all surfaces, but the thickness of the tin layer varies.

The “electrotin” solder surface provides a planar surface and good solderability for finepitch components. We explain the most important properties of the solder surface.
Electroless nickel-gold is the most widely used solder surface for printed circuit boards in Europe. Learn the reasons in our blog article.
The solder surface, final surface or also called PCB finish, is a thin metallic or organic layer that the PCB manufacturer applies to the copper surfaces of the component connections (solder pads). The solder surface covers the exposed copper on the PCB and preserves the solderability within the guaranteed storage period of the PCBs under
