These BGA rework stencils provided by Soldertools.net make it simpler for you to place BGAs while repairing solder mask damage. StencilQuik™ BGA rework stencils have a side benefit of being able to repair solder mask underneath the location as the polyimide is an elegant "band aid" for the repair of the damaged mask.
StencilQuik™ are flexible solder paste stencils manufactured from a polyimide film with a high temperature adhesive covered with a release liner. They allow you to simplify area array device placement/replacement saving 50% or more of the time required to rework BGAs or CSPs.
