HASL stands for Hot Air Solder Leveling. ENIG stands for Electroless Nickel Immersion Gold. Both HASL and ENIG are two different types of a surface finish used for plating the Printed Circuit Boards(PCB).
HASL is less environment friendly than ENIG. Choosing ENIG over HASL, reduces the use of lead and emission from flux and fusing oil.
HASL has a excellent solder-ability and has a good shelf life.
ENIG has excellent corrosion resistance, it is good for aluminum wire bonding, excellent for fine-pitch technology, excellent solder-ability and excellent shelf life.
When it comes to cost, HASL is cheaper than ENIG for 2 layer boards. As we go for more layers, the cost for HASL becomes almost the same as that of ENIG plating. The pictures attached are not so good quality. You can also follow me at **broken link removed**.
