The process consists of immersing circuit boards in a molten pot of a tin/lead alloy and then removing the excess solder by using 'air knives', which blow hot air across the surface of the board.One of the unintended benefits of the HASL process is that it will expose the PCB to temperatures up to 265°C which will identify any potential delamination issues well before any expensive components are attached to the board.Advantages:Low CostWidely AvailableRe-workableExcellent Shelf LifeDisadvantages:Uneven SurfacesNot Good for Fine PitchContains Lead (HASL)Thermal ShockSolder BridgingPlugged or Reduced PTH's (Plated Through Holes) Company ProfileWe know almost all electronic engineers got a problem to found a right manufacturer to make  PCB prototypes & small batch order because big factories don't want to make small orders, they always gave high price and very long delivery time, they can't provide fast delivery service.
