Flextac BGA Rework Stencils

Transcription

1 Description These flexible solder paste BGA rework stencils are laser cut from high quality, anti-static polymer film with a residue-free adhesive backing. Because they are self-sticking, no tape or fixturing is needed. The adhesive seals around each BGA pad to prevent solder paste from bleeding under the stencil when the paste is applied. Easy to use and leave no residue on the board surface. Typical BGA rework stencils are made from metal and require fixturing or taping to position them and hold them in place. Metal stencils warp easily, and if the circuit board has undulations in the board surface, the metal stencil will not sit flat. Since there is no gasket-like seal, solder paste can easily bleed under metal stencils when paste is applied with a squeegee. Also solder paste can spill out over the sides of flat metal stencils contaminating the circuit board surface. Metal stencils require tedious stencil cleaning. To use metal stencils effectively, a high level of operator skill is required. Features & Benefits Residue-free adhesive backing seals around BGA pads to prevent solder paste bleed Laser cut ensures precise aperture size Disposable eliminates tedious stencil cleaning Flexible conforms to board surface Fold-up sides for easy placement and solder paste containment Low cost Packaged in a handy ESD safe carrying case
