Products

We don’t just sell PCBs. We sell sleep.

There are few parts in an electronic device that have such an impact on the final product as the printed circuit board. At first sight, PCBs differ little in appearance, irrespective of their inherent qualities. It is under the surface that we focus on the differences so critical to the PCBs’ durability and functionality. Customers cannot always see the difference, but they can rest assured that Cirtech EDA puts a great deal of effort into ensuring that their customers are supplied with PCBs that meet the most stringent quality standards.

The information below details some of the key capabilities that Cirtech EDA can offer and support today. You will find information here relating to the specific materials we can support, the PCB technologies or product types which we currently produce, as well as some of the tolerances which we can achieve.

The first category is what we call “standard” and means we can offer each individual parameters from multiple sources. The second is our “advanced” offering and this shows the very best that Cirtech EDA can offer, but here the supply chain or sourcing options are limited and in some cases this means that only one plant is capable of this parameter.

When using combinations of these parameters, you should always speak to one of our technical specialists.
