PCB Visualizer is Eurocircuits‘ digital engineering environment for analysing, visualising, and verifying PCB design data before manufacturing begins. It connects your design files directly to the manufacturing process, applying over 700 predefined DRC and DFM rules to confirm that your data is complete, correctly interpreted, and manufacturable. Engineers working on prototypes, NPI projects, or low-volume production use it to identify and resolve potential manufacturing problems while changes can still be made digitally, before a single board enters production. The sections below answer the most common questions about how PCB Visualizer works, what it checks, and when to use it.
How does PCB Visualizer work?
PCB Visualizer works by importing your PCB design data and processing it through Eurocircuits‘ manufacturing preparation engine. It creates a digital manufacturing interpretation of your design, a digital twin, that shows exactly how your data will be read and prepared for production. Engineers can inspect, interact with, and verify this interpretation before committing to physical manufacturing.
When you upload your design files, the tool analyses the data against the manufacturing parameters of the pooling service you have selected. It checks data integrity, reviews the PCB build-up using an integrated editor containing over 970 pre-defined builds, and applies its full set of DRC and DFM rules automatically. The process is fully automated, but the results are presented interactively: you can view flagged issues, understand what has caused them, and in many cases approve automatic repair suggestions directly within the platform.
This approach is what distinguishes PCB Visualizer from a passive file viewer. Rather than simply displaying your Gerber files, it interprets them the way a manufacturer would, surfacing conflicts and ambiguities that would otherwise only become apparent during production, or worse, after delivery.
What does PCB Visualizer actually check?
PCB Visualizer checks four interconnected areas: data integrity, manufacturability, PCB build-up definition, and, for assembly projects, component and BOM information. Together, these checks cover the most common sources of avoidable manufacturing problems in prototype and low-volume production.
On the PCB side, the tool verifies that your dataset is complete and unambiguous, then applies over 700 predefined DRC and DFM rules to assess whether the design can be manufactured using the selected service. It evaluates conductor widths, track clearances, drill dimensions, annular rings, copper-to-edge distances, solder mask features, and stack-up consistency, the specific constraints that determine whether a board can be reliably fabricated.
For assembly projects, the PCBA Visualizer extends these checks to component data. It verifies component identities, manufacturer part numbers, packages, and the consistency between BOM information and placement data. Eurocircuits‘ verified component database, containing 450,000 confirmed parts, supports this process, helping engineers identify component data problems before assembly preparation begins rather than during it.
If issues are found, they are reported directly within the Visualizer interface. Where possible, automatic repair solutions are proposed for the engineer to review and approve, saving time that would otherwise be spent on back-and-forth clarification with the manufacturer.
What types of PCB errors does it catch before production?
PCB Visualizer is designed to catch manufacturability and data preparation errors, the category of problems that cause unnecessary prototype iterations, production delays, and avoidable costs. These are distinct from functional design errors, which require prototype testing to identify.
Common errors caught before production include:
- Insufficient track clearances or conductor widths that fall outside the manufacturing capability of the selected service
- Drill sizes or aspect ratios that conflict with the fabrication process
- Annular ring dimensions that do not meet production tolerances
- Copper features placed too close to board edges
- Solder mask openings that are incorrectly sized or positioned
- Stack-up conflicts or undefined build-up specifications
- Incomplete or inconsistent Gerber data that would require clarification before production could begin
- BOM entries with missing or ambiguous manufacturer part numbers
- Mismatches between placement data and component packages
It is worth being precise about what PCB Visualizer cannot catch: it does not verify whether your electronic design functions correctly. Functional validation remains the responsibility of engineering development and prototype testing. The tool’s value lies in eliminating the avoidable manufacturing problems that sit between a working schematic and a reliably produced board.
How is PCB Visualizer different from standard DRC tools?
Standard design rule check tools in PCB design software verify your layout against the rules you have defined in your design environment. PCB Visualizer verifies your design against the actual manufacturing parameters of the production process it will go through, a fundamentally different reference point.
Most EDA-based DRC tools check whether your design respects the constraints you have set up in your design tool. They do not know how a specific manufacturer will interpret your Gerber files, which build-up will be applied, or whether your data is complete and unambiguous from a production preparation perspective. Gaps between designer intent and manufacturing interpretation are a common source of avoidable problems that standard DRC tools do not surface.
PCB Visualizer applies over 700 DRC and DFM rules that reflect Eurocircuits‘ actual manufacturing capabilities and pooling services. It also performs data integrity checks, build-up verification, and, for assembly, component and BOM validation. This makes it a pre-production verification environment rather than a design-stage rule checker. The distinction matters: it operates at the boundary between design and manufacturing, not within the design tool itself.
Who should use PCB Visualizer and at what stage?
PCB Visualizer is most valuable to electronics engineers, PCB designers, and hardware developers who are preparing designs for prototype manufacturing, NPI, or low-volume production. It is particularly relevant when design data is being finalised and the cost of discovering manufacturing problems after ordering would be significant.
The most productive point to use PCB Visualizer is before placing an order, ideally as a standard step in your pre-production workflow rather than as a reactive check. Uploading design data early gives you the opportunity to resolve flagged issues while changes are straightforward. Discovering the same issues after a board has been ordered, or after a first prototype build has returned with problems, is considerably more expensive in both time and cost.
For NPI projects, where the objective is to transition from a validated prototype to stable, repeatable manufacturing data, PCB Visualizer supports the design for manufacturability review that is essential to a smooth handover. Engineers working under time pressure to shorten iteration cycles will find that resolving data and manufacturability issues digitally, before physical production begins, is one of the most effective ways to reduce unnecessary delays.
The tool is available 24 hours a day, seven days a week, in six languages, and is integrated directly into the Eurocircuits customer account. There is no requirement to place an order before using it.
Is PCB Visualizer free to use?
Yes, PCB Visualizer is free to use. Engineers can upload PCB and PCBA design data, run the full set of DRC and DFM checks, review manufacturing interpretations, and interact with the results without any obligation to place an order.
Access requires a Eurocircuits customer account, which is also free to create. Once logged in, the Visualizer is available at any time, supports instant online pricing calculations, and provides real-time feedback on manufacturability. The tool functions both as a pre-production verification environment and as the platform through which orders are placed, but using it for verification carries no cost and no commitment.
This makes it practical to incorporate PCB Visualizer into your standard design review process, running checks on each design iteration before finalising data for production rather than reserving it only for the moment an order is ready.
