4" × 4" Prototyping Board for 128- to 240-pin Quad Flat Packages with 0.5mm spacing This prototyping PCB supports an IC of up to 240 pins in QFP package with 0.5mm pitch.
This product utilizes the patented Schmartboard|ez technology to make soldering surface-mount devices easy. Your SMT part will sit in grooves that hold it in place and already have solder in them. So all you need to do is put a chip in the grooves, apply flux, and use a small enough soldering tip.
Connect multiple SchmartBoards together! Every SchmartBoard has small notches along its sides which allow you to connect any number of them together in any combination. For example, you can attach this SchmartBoard to prototyping SchmartBoards that carry interfaces and other electronics. Purchase a set of the Mechanical Bridge Interconnects available in the options below if you want to be able to combine your SchmartBoards.
