Scan order

The connector side applies to both boards and turns each whole board. Scan order assigns channels to connector pins (pin 1 is marked in the previews); neither moves copper on the board.

Connector size

Row connector pins

Column connector pins

Leave empty for one contact per channel. A larger ZIF connector adds isolated NC contacts at the unused positions.

Fan-out traces

Trace width

Trace spacing

The traces leave the sensor thin, run as a tight bundle and widen again at the gold fingers.

Row traces

Diagonal: each row trace runs as a slant from its row's end beside the field, so the board is narrowest at the tip; both boards share one outline down to their tails, which leave one bottom edge, stacked (the Row tail on the centred Column tail; they part to their own connectors). With both sides the Row pins fold (ROW_01, 03, …, 04, 02). It is built with Gen by Surface's rules (0.5 mm field margin, up to 64 columns, tails from 7.5 mm). Straight channel: the row traces run in one channel beside the field, the Row pins in order (up to 32 columns, tails from 7.0 mm).

Proposals

Only the taxel field stays on the surface: the Row traces beside it, the Column fan-out and both tails may leave it, beyond its sides and the base edge.

Generate

Builds the chosen proposal; its previews and downloads appear below.

After Generate, the build is mapped onto the part and checked here.

Step by step: the FlexiTac fabrication guide.

Gerber ZIPs are deterministic Direct Gerber / JLC review candidates: upload top and bottom separately, then verify the outline, the coverlay openings and the PI stiffener listed under Standardized manufacturing. They are not EasyEDA-native exports and are not production approval. The EasyEDA Pro projects ZIP holds one native .epro2 project per board: import it into EasyEDA Pro (pro.easyeda.com, File > Import > EasyEDA/JLCEDA (Professional)), check FPC mode, the stiffener and DRC there, and let EasyEDA write the Gerbers and the order (README_EASYEDA.txt). Every file name starts with the build id. The design and layout JSON downloads are readable copies of the shown build; the project review ZIP carries their canonical, byte-stable versions.
