    Solder Anti-Migration Barrier
    Perancea has developed an effective yet low cost solution for the preventionof solder creepage up the sides of its PCB moutning screening enclosures during automated and reflow soldering processes. If solder migration is an important consideration in your application, Perancea can provide a solder/tin free barrier that will prevent solder wicking up the side of the can or frame.The barrier essentially provides a physical break in the plating so that solder will only flow to the height of the line and not beyond it thus ensuring good quality solder joints. The linear barrier is set around the circumference of the enclosure at the optimum height from the PCB to suit individual applications. It is normally 0.15mm wide with a depth commensurate with the surface finish.
