Terms of Service

Who we are

PCBSignoff (pcbsignoff.com) is a schematic and PCB design review service run by CircuitNexa ("we", "us"). These terms apply when you visit the site, upload files, request a review or pay for one. By doing any of these you agree to these terms and to our Privacy Policy.

If you use PCBSignoff for a company, you confirm that you can agree to these terms on its behalf. You must be at least 18 years old.

The services

• Free AI review: an AI review of your design, emailed to you as a severity-rated report.
• Schematic Review ($99): the AI review plus datasheet-level pin checks, verified by an engineer.
• Full PCB Review ($249): the Schematic Review plus BOM, Gerber, pick-and-place and layout review, verified by an engineer.

We accept files from Altium Designer, KiCad, EasyEDA, Autodesk Eagle and Fusion Electronics, OrCAD, Allegro, PADS, Proteus and DipTrace, or PDF schematics, BOMs and Gerber files from any tool. Paid reviews cover boards of up to 4 layers and about 150 components. For larger boards we will agree the scope and price with you first.

We may ask for more files, or decline a request, for example if files are unreadable or outside our scope.

AI-generated content

Our reviews use AI, including Claude models from Anthropic, guided by our own library of PCB checks. AI can make mistakes. It can miss real problems, report problems that do not exist, and misread part numbers, pins or datasheets.

The free AI review is not checked by an engineer. Paid reviews are verified by an engineer, but no review, human or AI, can find every problem. You must check every finding and confirm your design yourself before you order boards, components or assembly.

Our reports are engineering advice. They are not a certification, and they do not confirm compliance with safety, EMC, regulatory (for example CE or FCC), medical, automotive or aerospace requirements.

Free AI review

You may request one free AI review per email address per month. We aim to email the report within 24 hours but do not promise it. We may change, limit or stop the free review at any time. It is provided "as is".

Paid reviews and payment

• Prices are fixed, shown in US dollars, and exclude any taxes, duties and bank or transfer fees, which you pay.
• After you upload your files, we check them and send you a Wise invoice, normally within one business day. You pay through Wise by card or bank transfer. If you prefer GBP, EUR or AUD, ask us to invoice in that currency.
• If your files are incomplete, or your board is outside the included scope, we will tell you before we invoice you.
• We start work when your invoice has been paid and we have all the files we need.
• We aim to deliver within 48 to 72 hours. This is a target, not a promise. Missing or unreadable files cause delays.
• Each paid review includes one round of follow-up questions about the report. Reviews of changed designs, and any extra work, are priced separately.

Refunds

• If we cannot open or review your files, we refund you in full.
• If you ask to cancel before we start work, we refund you in full.
• Once we have delivered your report, the fee is not refundable, except where the law requires it.
• If you think a report contains a mistake, tell us within 14 days and we will look into it.

Your files

You confirm that you own your files or have the right to send them to us, and that sending them does not break any agreement. For example, an NDA may stop you sharing a design with contractors or AI service providers. Check before you upload.

Do not upload malware, unlawful material, or designs that are classified or export-controlled in a way that prohibits sharing them with us. Please leave out personal data that is not needed for the review.

Confidentiality and data

Strict NDA by default. Everything you upload, and every report we produce for you, is confidential. This section works as a non-disclosure agreement between you and us. It applies automatically from the moment you upload, and there is nothing for you to sign.

• We use your files only to provide your review.
• We do not disclose them to anyone except our engineers, who are bound by written confidentiality obligations, and the service providers needed to run the review, who handle them only to provide their service. They are listed in our Privacy Policy.
• This does not cover information that is already public through no fault of ours, or disclosure the law requires. Where the law allows, we will tell you first.
• These duties continue after we deliver your report and after we delete your files.
• We delete your files 30 days after we deliver your report, or within 30 days of upload if no review is delivered.
• We may keep anonymised findings, never your design files, to improve our checks and service.
• If you need your own NDA signed, ask us. If it conflicts with these terms, the signed NDA prevails.

Intellectual property

You keep all rights in your designs and files. You may use the reports we deliver for any purpose, including sharing them with your team, manufacturers and investors.

We keep all rights in our check library, methods, templates and software. You may not copy, scrape, resell or systematically extract our check library, for example by submitting designs in bulk to reconstruct our checks.

Acceptable use

Do not misuse the site. That includes automated or bulk submissions, attempts to get around the free review limit, attempts to break or overload the site, and any use that breaks the law. We may refuse service or block access if you do.

No warranties

To the fullest extent the law allows, PCBSignoff and all reviews are provided "as is", without warranties of any kind. We do not promise that a review is complete or error-free, that it suits a particular purpose, or that your board will work or pass testing.

Limits on our liability

Nothing in these terms limits liability that cannot be limited by law. Otherwise, to the fullest extent the law allows:

• our total liability for any claim relating to a paid review is limited to the fee you paid for that review;
• we are not liable for any loss relating to the free AI review;
• we are not liable for indirect or consequential loss, or for lost profit, revenue or business. This includes the cost of boards, components, assembly, shipping, respins, tooling, delays and product recalls, even if we were told they might happen.

Third-party services

The site uses services from others, such as Wise for payments, Tally for forms and uploads, and Cloudflare for hosting. Links to WhatsApp and LinkedIn lead to services we do not control. Their own terms and privacy policies apply, and we are not responsible for them.

Suspension and ending

We may suspend or end your access if you break these terms. You can stop using PCBSignoff at any time, and you can ask us to delete your files earlier by emailing us.

Changes to these terms

We may update these terms. The date at the top shows the latest version. Changes apply from when we post them, but they do not change the terms of a paid review you have already ordered.

Governing law

These terms are governed by the laws of Malaysia. If we disagree about something, please email us first so we can try to sort it out. If we cannot, the courts of Malaysia have jurisdiction. If you are a consumer, you may also have rights under the laws of your own country that these terms cannot remove.
