The BrownDog™ 031102A is an SO28 (SOIC-28) to 28 pin DIP adapter, suitable for both narrow and wide-body SO28 devices. With the electronics industry’s move to surface-mount technology, many integrated circuits are now only available in SMT packages. While SMT is preferable for high-volume, automated manufacturing, prototyping and evaluation with this type of IC is difficult without a way to easily connect test probes to their contact pins. And compared to its through-hole siblings, it is difficult to remove an SMD from its circuit board without expensive hot-air rework equipment, and without damaging the component itself or the PCB. The 031102A adapter provides a convenient solution when working with SO28-package devices in these situations. As a pin-to-pin adapter, an SO28 component installed on the 031102A will be functionally equivalent to a 28 pin DIP device. Whether you’re replacing an existing DIP device, designing for interchangeability, or in prototyping and evaluation, the 031102A is the perfect answer.

The 031102A is made with contemporary PCB design techniques, software, and manufacturing. With electroless nickel immersion gold (ENIG) surface finish for conductivity and flat surface planarity, there will be no detectable difference between an SO28 device (0.050 in./1.27mm pitch) mounted to the 031102A and an equivalent DIP device.
