About the Tqva cob PCB

Tqva cob is an open source PCB design by wafer-space, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 14 × 16 mm, with 6 components from 3 distinct parts.

By type, the board carries 4 capacitors and 2 ICs.

From the project

Wire bonded chip on board PCB designs.

This directory holds the design files for Run 1 of the wafer.space chip-on-board (COB) breakouts.

Our current padframe and wirebonding layouts follow the Tiny Tapeout convention of 74 pads. All ground (GND) connections are tied together in the Default Breakout COB package.

Space has been allocated for optional components such as decoupling capacitors and other passive elements.
