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 i***cting 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 Corro***in WhiskersNot Good for Multiple Reflow/Assembly ProcessesDifficult to Measure Thickness Co***ny 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 t |
