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

	Quantity

	Lead-time

	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?

	Schematics

	Netlist

	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
