BGA Rework Stencils

Re-usable and disposable
Self-adhesive
Easy to use and align
Best paste print solution for rework

Description
Flextac BGA Rework Stencils are self-sticking solder paste stencils. These laser cut, polymer stencils use a residue-free adhesive similar to Post-it® Notes. The self-sticking adhesive seals around each BGA pad to ensure that solder paste will not bleed under the stencil when the paste is applied. Disposable Flextac Stencils are easy to use and will not leave any residue on the board surface.

Flextac BGA Stencil

Issues with previous technology
Before Flextac, BGA rework stencils were fabricated from metal and required 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, a 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. To use metal stencils effectively, a high level of operator skill is required.

The innovation
Flextac BGA Rework Stencils are laser cut from a high quality, anti-static polymer film which is the same thickness as metal stencils. To use, the operator first folds the pre-scored side tabs and then peels off a release liner from the bottom side of the stencil. The operator holds the side tabs whilst placing the Flextac Stencil in position. If it is not correctly positioned, it can simply be removed and repositioned. The side tabs also serve as solder dams preventing overspill. No external taping or fixturing is used to hold Flextac Stencils in place.

Next the operator applies a small dab of solder paste and uses a standard squeegee to spread the paste. Since the self-tack adhesive seals around each BGA pad, the operator can make as many passes as necessary with the squeegee to assure proper aperture filling. The Flextac Stencil is then peeled up leaving a perfect deposit of solder on each pad.

Although Flextac Stencils are disposable, they can be used several times. They eliminate tedious stencil cleaning and reduce operator exposure to solder paste.

Flextac BGA Rework Stencil Kit is packaged in a rugged ESD safe case.

The Kit includes 20 different sizes of BGA rework stencils, a spatula handle and three sizes of spatula blades.
