Frequently Asked Questions

1. What type of formats can you accept?
Gerber (RS274-D) with Aperture file
Gerber extended ( RS274-X). This is preferred.
DXF (1:1 scale)
AutoCAD DWG (1:1 scale)
HPGL (for fab drawings only)

2. What information do you need to Quote flex circuit fabrication?
Part Dimension (X and Y)
Number of layers
Materials, construction and type of flex circuit (Rigid-flex, Multilayer, etc.)
Surface Finish
Any special process requirements such as microvias, laser skiving, traces below 75 micron, tight tolerance (less than +/- 0.002"), copper alloys, etc.
Any control impedance requirements
Minimum hole size and pad size

Minimum trace and space
Gerbers and fab prints are preferred to perform a thorough design review prior to quoting, as well as figuring out the best way to fit the part on a panel.

3. What do you need for manufacturing my flex circuits?
Gerber files
NC Drill file (preferably in Excellon format)
Fab Drawing (which includes board dimensions, material call out / construction, notes for specification and hole schedule)

4. What do you need for assembly of flex circuits?
Bill of Materials
Assembly Drawing
Assembly Data sheet for components such as BGAs
Complete Kit for consigned orders

5. Can you calculate and build Impedance Controlled flex circuits?
We can model impedance values for microstrip, coated microstrip, stripline, asymmetric stripline and differential pair. We can build a test coupon for TDR testing upon customer's request. We will build boards to your specifications for impedance control and double check your build with our software.

6. What do you need to layout Flex Circuit Design?
Mechanical Drawing or Board Outline
BOM and applicable parts list (including data sheets if available)
Special requirements such Controlled Impedance, Shielding, Flexing cycles, Environmental requirements, etc.
Pad pattern for any wire bond area
Parts placement specification
