What files do you need?
KiCad, Eagle or EasyEDA project files, or a schematic PDF with Gerber files and a BOM (CSV or XLSX). We don't currently accept Altium project files; export a schematic PDF, Gerbers and BOM instead.
FAQ
PCB design review: frequently asked questions
Files, turnaround, confidentiality, cost and what you receive.
How long does a review take?
48 hours for standard reviews; 24 hours at 1.5× and same-day at 2× when availability is confirmed.
Is my design kept confidential?
Yes. Files are shared under a mutual NDA, stored securely and used only for your review.
What does a review cost?
From ₹2,500 for one two-layer board with up to 100 components; complexity points are added for more layers, components, power, RF and interfaces. The configurator shows the exact total before payment.
What do I receive?
A Design Assurance Report with every finding ranked by severity (critical, significant, verification, improvement), its impact and the datasheet or standard behind it, plus one clarification round. Findings identify risks and their basis; PreBuild does not prescribe design changes. Any design change, and its validation, remains the responsibility of the design owner.
Does a review guarantee my board will work?
No review can guarantee that. It removes preventable design errors before fabrication; bench bring-up and testing are still needed.
Do you review firmware or enclosures?
No. Reviews cover hardware only: schematic, PCB layout and BOM. Firmware and mechanical/enclosure design are not included.
Do you work with clients outside India?
Yes. We review designs from anywhere. Prices are shown in INR, and international cards are accepted through Razorpay.
