Why create stackups with Speedflex HDI?

Speedflex HDI is a comprehensive stackup design environment for PCB fabricators, pre-layout engineers and value-add PCB brokers. By collating libraries of materials, costs and suppliers with critical design data, such as transmission line specifications or impedance control, Speedflex HDI lets you produce error-free build documentation. .

What will Speedflex HDI do for me?

OEM designers
Speedflex HDI's end-to-end approach to stackup design allows you to create documents that can be shared at every stage of the PCB supply chain and drastically reduces the time you need to create, document and control PCB layer stackups.

PCB fabricators
For PCB fabricators, Speedflex provides the flexibility to quickly calculate the possible impact of substituting alternative materials to improve manufacturability and reduce cost while maintaining the specified parameters and performance of the board.


Easy graphical stackup display
The Speedflex navigator quickly guides engineers though the stackup process and presents the complete assembly in a graphical display that highlights the flex regions within the flex-rigid PCB. User-definable settings within the Speedflex navigator allow engineers to display layers in transparent, invisible or 3D mode. 

Sub-stack reordering

Speedflex HDI makes re-ordering and renaming sub-stacks quick and easy with the Speedflex Navigator. You'll find this especially useful for HDI constructions.

Stack descending

Simply select the sub-stack and move it left or right within the Navigator window:

Speedflex's technical reports print the final stack in a range of high quality formats.

Speedflex HDI Tech Report

A range of materials including flexible adhesives, bond ply and FlexiCore can be enabled or disabled for each layer, and impedance structures can be added to each sub-stack. 

Definable colours per material
Speedflex gives you the ability to set and store individual material colours via the material Properties dialog. Printing will reflect the colour changes

Powerful stack browser / search option
Utilise alternate data streams (ADS) to store summary stack information, including layer count, thickness, copper thickness, etc. Speedflex's powerful search mechanism allows you to specify a filter criteria and match the relevant files; your selected file is automatically loaded into the stack editor.


Without Speedflex...

Flex-rigid PCB manufacture can be expensive in money and time and using the traditional, informal methods of exchanging stackup information is prone to misinterpretation as the stack is passed around the supply chain. Errors in stack documentation can all too easily result in board scrappage and remanufacture.

Interactive Speedflex brings reduced cost and enhanced reporting capability...

Speedflex for cost control
Speedflex allows OEM designers and PCB fabricators to control the traditionally high cost of flex-rigid PCBs. Using comprehensive, standard or custom libraries of suppliers, material lead times and costs, Speedflex can eliminate hours of complex calculations by quickly displaying the predicted effect of using different materials and suppliers on a board’s electrical performance, cost and manufacturing yield. This ultra-fast process means that more options can be explored to find the optimum combination of materials and suppliers for each board.

High quality error-free documentation
Speedstack's professional, high quality documentation is continued in Speedflex. Once the flex-rigid stackup is complete, Speedflex also adds flex-rigid report capability to the Speedstack report generator. Documents can be exported in a range of industry-standard formats including JPEG, Gerber and PDF files so that every company and individual within the fabrication process, from PCB fabricators to brokers, can have the same clear instructions and parameters.

Adding the Atlas Si GHz-PCB test system and CGen Si coupon generator to the Si9000e insertion-loss control tools in Speedflex HDI Si gives you complete control over insertion losses throughout the fabrication process
