The ISn protects the nderlying copper from oxidation over its intended shelf life.Copper and tin however have a strong affinity for one another. The diffusion of one metal into the other will occur inevitably, directly impacting the shelf life of the deposit and the performance of the finish. The negative effects of tin whiskers growth are well described in industry related literature and topics of several published papers.Advantages:Flat SurfaceNo PbRe-workableTop Choice for Press Fit Pin InsertionDisadvantages:Easy to Cause Handling DamageProcess Uses a Carcinogen (Thiourea)Exposed Tin on Final Assembly can CorrodeTin WhiskersNot Good for Multiple Reflow/Assembly ProcessesDifficult to Measure Thickness 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.
