Designing your Flexible Circuit
Before your engineers design the flexible circuits, he can communicate with us knowing that we are going to understand what it is they need, and that we can offer the best way to get them there. The follows basic three steps to design your flexible circuits.
Step 1 - Gather the necessary informations:
Request these guides before starting your design process:
- Learn the general design tips, dimensional tolerances, conductor design data, and artwork layout, etc.
- Get a brief glance at our production capability to get the design assistance and specifications for flex circuits.
- Learn the information about material of FPC
- Knowing tolerance of flex circuits
Step 2 - Determine circuit outlines and conductor routing:
The first step in flex circuit design is to translate schematics and package geometry into flex circuit outlines and artworks. Paper cutouts are one way to achieve this. First, cut out a piece of paper which can be folded to reach all points which the circuit will connect. Then lay the paper flat and trace conductor routing between connection points. Make additional cutouts to represent extra layers. Specify foil thickness and conductor widths to match current requirements.
You can find some simple calculator to calculate the trace (conductor) width for circuit board:
PCB Trace Width Calculator: Based on a curve fit to IPC-2221 (formerly IPC-D-275);
