These are now replaced by the new and improved version! Now available for a wider variety packages than ever before

These are premium quality breakout boards for some of the common fine pitch SMD packages. We've received a number of inquiries about offering a breakout board for some of these packages - DFN, MSOP, and WSON. In some cases, manufacturers use other names to refer to similar packages, or may or may not include an exposed pad in the middle.

Two of the most common pitches for DFN/MSOP and similar packages are 0.5mm and 0.65mm - these boards support 0.65mm with no exposed pad, and with a 1.6mm wide exposed pad in the middle, and 0.5mm with no exposed pad, with a 0.9mm wide one, and with a 1.5mm wide one sometimes marketed as WSON-8. These breakout boards connect each pin of a DFN/MSOP/similar package to two holes (for convenience when a pin must have multiple connections.

This line also includes a breakout board for VQFN-16 package, and a breakout board for the rectangular QFN-28 (4x5 mm) that Analog Devices seems to like so much, and for (T)SSOP-28-EP. For larger variants of the normal square quad flat pack packages (TQFP or QFN) we have a line of prototyping breakout boards available . There are two designs per board (one per side),

All of these boards have two mounting holes sized appropriately for a #4 or 3mm screw, and support two package footprints, one on each side of the board. Where there is an exposed pad, it extends beyond the edges of the chip, and has through-holes there, for both connecting to it, and to aid in hand-soldering. All of these are now available in two package sizes with a small bulk discount - most of our customers were buying more than one three-pack, and this interacts better with the "per item" add-on shipping rates.
