Laser cutting adhesive films laminated to kapton is often the process to produce reball stencils for BGA sockets.  A number of companies have created products for reballing and most are really quite simple, user friendly and effective.  A-laser has regular requests for BGA stencils using a variety of adhesive backings and we find that each adhesive behaves somewhat differently when processed using the UV laser cutting systems.  It is very important that our customers work with us to determine the proper adhesive.  Laser cutting services produce quotes based on time and complexity, so to reduce your costs we want to use the most laser friendly materials possible.

Our laser cutting service works with a wide variety of companies requiring various material combinations.  We’ve found ourselves often amazed at the variation in cut speed and quality from one adhesive to the next.  It is ideal to involve our engineers early on in your processes to allow for input regarding the properties of these materials.  Our lasers cutting systems have very little thermal influence on the these materials, allowing them to function at their optimal levels.  Additionally, the ablation process leaves behind virtually no residue or burrs.  A-lasers laser cutting service is committed to providing our customers with the highest level of quality available in the market today.
