Saturn PCB Design Toolkit Version 4.6.1 including the new IPC-2152 Update!

The Saturn PCB Toolkit is the best resource for PCB related calculations you can find.
It incorporates many features that PCB designers and engineers are in regular need of like current capacity of a PCB trace, via current, differential pairs and much more. Please download our PCB Toolkit today for free and enjoy!

We are compiling a list of companies that are using our PCB Toolkit.
This list is also use to inform our PCB Toolkit users of program updates.

We are working to dramatically improve the amperage values for both the conductor and via calculator. The current version of the PCB Toolkit uses the general chart from the IPC-2152 and in some cases can be too conservative.

We have also added quite a few features so please be sure to send us as much feedback as you can.

Please see comments below for V5 enhancemnets.

NOTE:

In order to understand the PCB Toolkit version differences, I have added this brief description of the version series. If you are not yet familiar with the IPC-2152 then please be aware that there are two separate charts for finding conductor current vs. temperature rise.

PCB Toolkit Version 3 series:
This version uses the IPC-2221 formula for finding conductor current vs. temperature rise. The IPC-2221 has been superseded by the IPC-2152 for finding conductor current vs. temperature rise and is now obsolete.

PCB Toolkit Version 4 series:
This version uses the IPC-2152 “Conservative” chart for finding conductor current vs. temperature rise. The conservative chart in the IPC-2152 is really just the internal chart from the IPC-2221 so that was the formula used. Version 4 series is accurate to the IPC-2152 but may be too conservative in many cases.

PCB Toolkit Version 5 series:
This version uses the IPC-2152 “Universal” chart for finding conductor current vs. temperature rise. The universal chart in the IPC-2152 has no formula associated with it so we have been working on developing our own formulas for current. We feel that all values in the version 5 series are within +/-10 of measured values on the universal chart.

Program includes:

PCB Via Current Calculator per IPC-2152

Version 5.0 Beta 2 Updates & Additions:

Significantly changed how the program calculates amperage to better match the IPC-2152 charts.

Please note that the amperage value has a slight drop at 10,20,30,40,50,60,70,80,90,100,200,300,400,500,600 & 700sqmils.
This is due to the multiplier used for each cross sectional area range. All values are within +/-10% of the chart values however.

Version4 series PCB Toolkit follows the new IPC-2152 chart as well but uses the general chart which can be too conservative in some applications. Implementing the new IPC-2152 has been no easy task since no new formulas were produced in the document. This has forced us to derive at our on formulas for current vs. temprise so please check back often for updates to this V5 beta program.

Added microvia current vs. temprise support
Added power dissipation in dBm for via and conductor calculator
Added dual monitor support for dialog boxes
Added broadside coupled differential pair support
Added imperial units support to spiral inductor calculator
Added embedded microstrip support for conductor impedance
Added coplanar waveguide support for conductor impedance
Added degree symbols
Fixed F to C conversion for temprise
Fixed dropdown menu control vs. tab control
Added close button to about dialog box
Fixed Conductor Impedance selection list from B2
Added "Program Options" menu item for manually entering copper weight
Fixed install directory issue, now installs to V5 directory.

V4.0 Updates & Additions:
