Technical Support

Customers who purchased products from FlowCAD and have a valid maintenance contract have access to software updates and technical support. You can call our hotline and ask questions on how to operate the products and if you find a bug, you can report the bug as well to receive a software update. To explain the functionality of the tools our application engineers can make an individual web session with Fastviewer. Or we can share application notes and short video tutorials with you.

Recommended PCB Layout Service Providers

Recommended Service Providers
Seal of Approval

Time after time companies inquire with FlowCAD about service providers who can assist with a special project or overcapacity and who are familiar with OrCAD / Allegro tools. The list of recommended service providers only includes companies that can prove their qualification through verified customer references. Please note: the requirements are different and you should always make up your own mind whether the external service provider is suitable for the tasks at hand.

Recommended Literature

FlowCAD is often asked which books about PCB layout or signal integrity are recommended. We have listed here some books that our application engineers have read themselves and whose content we subjectively consider to be useful. This list is not exhaustive and FlowCAD has no commercial use for these book recommendations. If authors think that their books should be included here, please send us a preview copy. We will read and include it here if necessary.
