Q:How do we keep our prices low?
We have relationships with a large number of board manufacturers and can find the best source of PCBs to consistently save your cost, meet your development schedule, fulfill your prototyping or mass production needs. 

Q:What is Test NRE?
The Test NRE is a one-time "non recurring expense" for electrical test. This charge is optional but when paid, all circuit boards will be tested each and every time that part number and revision is ordered without additional charge. 

Q:When do you pay a tooling NRE fee for my printed circuit board?
You will only pay a Tooling charge if you go directly to Production (Custom Spec) without having ordered a Proto (Standard Spec) as a first step. We do not charge Tooling for Protos (Standard Spec) and neither do we charge Tooling if the proto (Standard Spec) is reordered for Production (Standard Spec). 

Q:If you only have a minor change in my design, do we charge Tooling NRE?
When you make any change to your printed circuit board, we assign it completely new tooling. This helps prevent old artwork or cnc programming from being used. Even a minor change will require the same process as new files, so a tooling charge may apply. Please contact your salesperson for details. 

Q:To what acceptability standards do we build?
IPC A600 Class 2 through IPC 6012 Class 3A
