Flexible Circuit Boards


Lara Grant, How to Build a Mini Synth. eTextile Swatchbook 2015

Creating Circuit Designs and Cut-files

Vocabulary:
circuitboard, pcb
component, part
datasheet
pins, leads
spacing, pitch
DIP, SMD…
schematic vs. circuit layout
trace width, clearance
solder mask
strain relief
bend relief (on flex pcb)
tear-drop shapes (flexpcb design guide)

Inkscape:  vector graphics editor for Windows, Mac OS X and Linux, free and open source. Can be used to create vector cut-files for vinyl cutter and laser cutter.

Illustrator: vector graphics editor for Windows, Mac OS X, part of the Adobe creative suit. Can be used to create vector cut-files for vinyl cutter and laser cutter.

Photoshop: photography and image editor for Windows, Mac OS X, part of the Adobe creative suit. Can be used to draw circuits that can later be transformed with vector software into cut-files.

Pen + paper + scan: Circuits can be drawn on paper and then scanned and converted into cut-files in a vector editor or directly in the Silhouette software.

Silhouette: Silhouette machines are affordabel dektop vinyl cutter. Vector files (dxf) can be loaded into the software to be cut, image files can be converted by the software into cut-files

TOOLS FOR AN ETEXTILE STUDIO PRACTICE

The topic of this workshop is making your own tool for your eTextile practice. eTextiles so far rely mostly on a combination of tools from different disciplines to complete electronic measuring tasks and textile making routine. Over the past years we started experimenting in designing tools specific to eTextile needs and wishes, exploring how tools stand for our practice and allow for improved routines in the making.

Tool-Vest

Tool Suite Vest - first prototype

Wearbale Studio Practice

Power Supply Pin Cushion

eTextile Tester

Multimeter Probes, Prototyping Cords

From the experience overt the past week, how would the ideal tool for your practice look like?
