Custom PCB design · BitnBolt
Schematic, layout, and production-ready files designed around your product—not a catalog board. Fabrication is optional; the design is the service.
Who this is for
You have a product idea but no in-house hardware designer. We turn the concept into a custom PCB you own and can manufacture anywhere.
Thesis, competition, or personal project—we design the board when a hobby kit is not enough.
Cost-down, size-down, new sensors, or a redesign of an aging board—without restarting from a blank company.
Bring Altium, KiCad, EasyEDA, or a reference board. We review, fix DRC/DFM issues, or redesign the parts that are wrong.
Process
You always know what step you are on and what files you will own. Boards are only ordered when you choose to validate the design in hardware.
We listen to the idea—product goal, constraints, budget band, and timeline. No polished deck required. A voice note or rough sketch is enough to start.
You getWritten scope summary and a clear “yes / not yet / better path” recommendation.
We choose the MCU/parts approach and draw a full schematic you can review—power tree, interfaces, and part availability considered up front.
You getSchematic drafts, BOM candidates, and design decisions documented with you.
We lay out the board for your size, connectors, and signal needs. You see previews and can request changes before the design is locked.
You getLayout files, Gerbers, BOM, and a design package ready for your fab or ours.
Optional prototype bring-up: power-on, checks, and a revision if something needs fixing. Design stays the product—boards are just how we prove it.
You getA stable revision, change log, and notes for the next build or production handoff.
What we cover
Most clients come for schematic and layout. Some only need a review or redesign. Prototype builds are available if you want them—never required to get a design.
Functional goals, I/O list, power source, size limits, certifications to aim for later, and “nice to have” vs must-have.
MCU, power, sensors, connectors, and passives chosen for availability in India / import lead times—not only datasheet ideals.
Layer stack, routing, footprints, silkscreen, and clearances tuned to your constraints—clean files you can send to any manufacturer.
We catch footprint mistakes, clearance issues, and assembly risks before you spend on boards.
Help powering the first boards, checking rails and buses, and planning the next revision if needed.
Gerber, BOM, CPL, and notes so your fab house—or an optional BitnBolt-assisted build—can run without guessing.
Deliverables
Exact package is set in the quote. These are the usual design deliverables—so “done” means files you own, not just a conversation.

Where parts are scarce
Pick-and-place / CPL
For assembly houses
Assembly drawing
Where parts go and how

What changed and why
Before you commit
We quote custom PCB design as the main line item. Optional prototype boards or assembly are listed separately if you want them—so you are not forced into a fabrication package. Complexity (layers, RF, high-speed, enclosure fit) drives the estimate.
Simple 2-layer designs can move from brief to reviewable layout in a couple of weeks once scope is locked. Dense multilayer, RF, or scarce parts take longer. We give a dated plan in the quote—not a vague “soon.”
You need a goal (“sense X, talk to Y, fit in Z”). We invent the circuit and layout. If you already have constraints (exact MCU, connector, battery), we design around them.
Project files for work you paid for are handed over as agreed. Your custom PCB design is yours—we do not reuse proprietary work for another client.
Common doubts
Yes. Many projects start with “I need a board that does X.” We turn that into requirements, then design. The brief form on this page is intentionally open—perfection is not required.
Project brief
Submitting opens your email with a draft to info@bitnbolt.in. No account, no payment—we reply about the custom PCB design first.
