Have Gerber files checked:
Design aid for printed circuit boards

At EVYTRA, your Gerber files and article-specific requirements are systematically compared and checked against your individual specifications. To do this, we use a standardized checklist that is always provided to our partners in the same format - for fast and error-free processing.

What is a Gerber file?

A Gerber file is a standardized file format that serves as a digital blueprint in the production of printed circuit boards (PCBs). It contains all the essential information needed to precisely produce the individual copper layers of a PCB. Gerber files - preferably in RS-274X or ODB++ format - are indispensable for the manufacturing process.

EVYTRA works with Gerber files, for uniform standards and error reduction in PCB production.

If you would like to have your Gerber files checked, please contact us.

Contents of a Gerber file

The Gerber file submitted to EVYTRA should contain the following information.

Copper layers: Information about conductor tracks, pads and other copper details of the individual copper layers
Solder resist mask: The Gerber file precisely defines which areas harden after the exposure process and remain covered with solder resist and which remain free.
Placement printing (screen printing): Markings and labels for components and orientation.
Drill holes: Position and size of all drill holes, including vias and mounting holes.
Contour outline: The outer contour of the PCB to define the final size.
Optional layers: Additional data for special requirements, such as captontape, via plugging, carbon printing, etc.

Steps for generating Gerber files

Design validation: Make sure that your PCB design is complete and has no design errors. Check for design errors, component placements and electrical connections.
Exporting the Gerber files: Use the export function of your PCB design software to export all required layers (copper, solder mask, position print, etc.).

Check the files: Use a Gerber viewer to check your files for errors.
Compression and sharing: Compress your Gerber files into a ZIP archive and add additional required specifications & drawings.
Transfer to EVYTRA: Send the compressed files to your EVYTRA team and sit back as we take over the rest of the process from here. Which begins with a check to ensure that the data is complete.

EVYTRA - your reliable partner in the procurement process

We take care of the data check, coordinate with the PCB manufacturer and clarify all specific requirements - from the surface finish and material specifications to individual special requests.

During the entire process, we will keep you transparently informed on request and proactively contact you as soon as further information is required. This leaves your head free for the essentials: Your projects.

How does EVYTRA check the data?

Once your Gerber data has been submitted, it is processed in a timely and structured manner. As part of a design rule check (DRC), we check the feasibility using our customer-specific expertise.

If there are any queries that fall outside the scope of either the manufacturer or EVYTRA, you will receive an Engineering Question (EQ) for final clarification.

As soon as all points have been coordinated, your design is optimally adapted to the production processes of the respective manufacturer. The production programs created are then transferred directly to the machines - and production can begin.

Rely on our many years of experience since 1969 for a smooth process and an impressive result!

How small can conductor tracks and spacing be?

This depends primarily on whether the layer is on the inner or outer side and on the copper base. For a thickness of 35 µm, the partner specifies 100/100 µm for the inner side and 127/160 µm for the outer side as the standard for series production. EVYTRA recommends allowing for a greater margin.

Why is CAM verification important?

Die CAM-Verifizierung ergänzt die technische Datenprüfung durch den Blick erfahrener Spezialisten. Sie hilft, Gerber-Daten auf Fertigbarkeit, Plausibilität und Eindeutigkeit zu bewerten.

How many layers are possible?

2 to 24 layers are specified as the standard for series production, with up to 32 layers indicated as the technological limit. The stack-up and material availability must be approved.

What is the most suitable microvia size?

Laser microvias ranging from 0.10 to 0.20 mm are specified; 0.125 to 0.15 mm and a microvia aspect ratio of up to 1:1 are robust starting points.

What data does a PCB manufacturer need?

Unambiguous data on layer, drilling, contour, stack-up, material, surface, impedance and tolerance, including revision and acceptance criteria.

What is a realistic impedance tolerance?

The tolerance of ±10 per cent applies to both single-ended and differential impedance. Tighter tolerances require separate validation.

What our satisfied customers say

Dear FELA team, I would like to take this opportunity to thank you for your outstandingly fast feedback as well as the samples! A cooperation as one would wish!

Cornelius Berns Thermokon Sensortechnik GmbH, Head of Sales

What our satisfied customers say

I also thank you very much for the top message and your support in this matter! We appreciate this very much. Through the early delivery, you have saved us a lot of trouble with our customer!

Also, love to your colleagues in the assembly of components, who made an extra effort for us! That's what I call top customer service.

Martin Isenschmid Impact Acoustic AG, Chief Purchasing Officer

What our satisfied customers say

For this reason, I would like to thank you in advance for the super support and cooperation. As I have already informed you, I am also passing on this positive feedback internally. The entire, open communication is very exemplary and so we were able to deal with the issue quickly.
