Si6000c (Obsolete)
Extracts Single ended and differential impedance on single dielectric builds

For single and multiple dielectric PCBs please refer to the Si8000m PCB Controlled Impedance field solver or the Si9000e Transmission Line (lossy line) field solver for frequency dependent modelling

End of life notice: June 30th 2008 close date for PolarCare renewal on Si6000.  PolarCare product support cease June 2009.  

Support only available in this situation:
a) You have an active PolarCare contract for Si6000 

Note: Support engineers report the protection keys used on the Si6000 cannot function on some new PCs. This is beyond Polar's control, and you may wish considering moving to Si8000m or Si9000e.

Field solving Impedance design system

The Field Solvers in the Si6000 allow you to accurately graph impedance against various PCB parameters. The Si6000 controlled impedance design system is a comprehensive controlled impedance design aid which can run stand alone as a Quicksolver, or the underlying engine can be applied directly though a Microsoft Excel user interface.

The Si6000 allows you to produce impedance controlled boards with maximum yields. You can also use the Si6000 to reduce the number of prototype iterations before production ramp up.

How? You have 3 powerful methods of using the field solvers.

One: A quick solving calculator lets you seek a target impedance by varying any one parameter, it could be line width, stack height or E_r; you choose the variable and set the goal seek — you can even set realistic targets for your own production limits. Use the Edit / Copy to Excel to take values from the Quick solver and paste directly into the Si6000 Excel spreadsheet

Two: A package of Microsoft® Excel spreadsheets allows direct access to the field solvers; you can graph any parameter you choose using the pre-prepared Microsoft Excel workbooks.

Three: Si6000 Expert mode allows you to access the Polar field solvers directly through Microsoft Excel and build them into your own workbooks. This lets you feed production data back into the field solvers so you can close the loop on your process control.

The Si6000b field solving impedance design system  offers advanced field solving methods to model most circuit designs and is totally complementary to the CITS500s and RITS520a manual and automatic  Controlled Impedance Test Systems. CITS measurement systems have been in use with leading PCB manufactures throughout the world since 1991 and Polar is recognised as a world leader in production line impedance testing. Polar's innovative product portfolio includes the Toneohm 950 short circuit locator which is able to pinpoint the physical location of shorts between maximum copper layers.

Please take a look at the controlled impedance application note pages — you will gain maximum benefit from your Si6000 if you read these supporting notes. These brief  articles help you translate the precision output of the field solvers into practical real world PCBs with good production yields.
