What is a PCB adapter? When do you need one?
Modern integrated circuits ship in surface-mount packages — QFN, BGA, TSSOP, SOIC — that you cannot prototype on a breadboard. The leads or balls are 0.5 mm or finer; breadboards expect 2.54 mm DIP pins.
A PCB adapter (sometimes called a breakout board or interposer) is a small board with the surface-mount footprint on top and DIP-pitch through-hole pads on the bottom. You solder your IC to the top, plug the bottom into a breadboard or socket, and your IC behaves like a DIP for prototyping.
Common reasons to use one:
- Evaluating a new IC before committing to a custom PCB.
- Building a one-off circuit on a breadboard or perfboard.
- Bringing up firmware on a chip you can't easily probe in its final form factor.
- Test fixtures and burn-in sockets.
- Teaching electronics — making SMD parts approachable for students.
Squidtronic adapters are routed by the same engineers who run our service work. We obsess over pad geometry, thermal vias on exposed-pad packages, signal integrity, and clean silkscreen pin-1 markers. Every board ships with ENIG gold finish for solderability and a clean visual. Browse all 260 →

We design custom adapters all the time. Send your IC's package drawing or datasheet and we'll quote a one-off or production-ready adapter.
