Complete Flextac BGA Rework Stencil Kit. 40 stencils of popular BGA designs plus application tools in an ESD-safe carrying kit. These flexible solder paste 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. Flextac Stencils are 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.

HOW FLEXTAC STENCILS WORK

You first fold the pre-scored side tabs and then peel off the protective cover film from the bottom side of the stencil. Holds the side tabs while placing the Flextac Stencil in position on the circuit board surface. If the stencil is not correctly positioned, you can simply reposition it. The side tabs also serve as solder dams preventing solder paste overspill. No external taping or fixturing is used.
You next apply a small dab of solder paste and uses a standard squeegee to spread the paste. Since the residue-free adhesive seals around each BGA pad, you can make as many passes with the squeege as needed 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.For a complete list of items included in this kit, contact Prime.For best pricing, place your order through Prime.
