Double-Sided Hot Air Solder Leveling (HASL) Red Oil Circuit Board ​ The double-sided HASL red oil circuit board is a type of printed circuit board with specific surface treatment and identification features. Both sides of the substrate adopt the hot air solder leveling process: molten tin alloy (lead-containing or lead-free) covers the copper surface and is leveled by hot air to form a uniform and flat tin layer. Meanwhile, the solder mask uses red ink, which not only
