Polar Instruments Speedstack v26 is a specialized software tool focused on the strategic planning and design of printed circuit board (PCB) layer stack-ups. The stack-up—the arrangement of copper layers and dielectric materials—is the foundational blueprint of a PCB, dictating its manufacturability, cost, electrical performance, and signal integrity. Speedstack empowers hardware engineers and PCB designers to create balanced, cost-effective stack-ups that meet target controlled impedance requirements, manage power delivery, and minimize crosstalk and EMI from the very beginning of the design process, preventing costly redesigns later.

(H2) Core Functional Capabilities of Speedstack v26

• Interactive Visual Stack-up Design & Editing
  Build and visualize your PCB layer-by-layer. Use an intuitive drag-and-drop interface to add signal, plane, and dielectric layers. Define core/prepreg materials, copper weights (oz), and dielectric thicknesses to create a balanced, manufacturable stack-up that prevents warpage.

• Integrated Controlled Impedance Planning & Calculation
  Plan and verify impedance targets directly within the stack-up. Define your critical nets (single-ended, differential) and their target impedance. Speedstack, using the same field solver engine as Si9000, instantly calculates the required trace widths and spacings for each layer, providing a complete impedance profile for the entire board.

• Material Library & Cost Analysis
  Make informed material choices. The software includes an extensive library of laminate and prepreg materials from major suppliers (like Isola, Rogers, Panasonic), with their key electrical (Dk, Df) and thermal properties. Compare different material sets and layer counts to optimize for performance, reliability, and cost.

• Manufacturing Output & Documentation
  Generate clear stack-up documentation for your fabricator. Speedstack produces detailed stack-up drawings, impedance tables, and Gerber-like layer diagrams that clearly communicate your design intent to the PCB manufacturer, reducing misunderstandings and ensuring the board is built exactly as specified.

(H2) The Speedstack Advantage in PCB Planning

Many signal integrity problems are "baked in" at the stack-up stage and cannot be fixed through routing alone. Polar Instruments Speedstack v26 elevates stack-up design from a back-of-the-envelope exercise to a precise engineering discipline. By integrating material data, impedance calculation, and manufacturability rules into a single proactive planning tool, it enables designers to make optimal trade-offs between layer count, material cost, and performance. For teams developing high-speed digital, RF, or any performance-critical electronics, using Speedstack is a best-practice step that de-risks the entire PCB development process and paves the way for a successful layout and fabrication.
