Doing BGA rework or reballing? This WHATAVAL stencil set has 130 pieces of stainless steel templates to handle various chip sizes and solder ball diameters. The set includes stencils for 0.30mm, 0.35mm, 0.40mm, 0.45mm, 0.50mm, 0.60mm, and 0.76mm solder balls, covering many common laptop, desktop, and graphics card chips (like Intel, AMD, and others). The stencils are made from 304 stainless steel with the right thickness – they're durable, won't deform easily under heat, and work with hot air stations. Each stencil size is marked on the surface, so you can quickly find the one you need. They come in a handy plastic storage box to keep everything organized. Using these templates makes reballing faster and more precise, reducing solder ball waste. Whether you're a repair tech, hobbyist, or working in a shop, this kit is a cost-effective way to have the right stencil on hand. Good for north/south bridges, GPU chips, and other BGA components. Makes those tricky repairs a bit easier!
