Since 1994, Circuits Central has helped innovators and OEMs move from prototype to production with responsive PCB and electronics manufacturing services, including quick-turn prototypes, NPI and low-to-mid-volume production. PCB assembly, testing, inspection and rework are performed in Canada at our Toronto-area facility, with flexible consigned, turnkey or hybrid material procurement.
Offshoring comes with hidden costs. Work with a local CM that adapts to your project, not the other way around.
Direct access to an engineer. No bots, no tickets.
Small runs, frequent revisions without volume pressure.
No timezone delays. Problems solved in hours, not days.
Scale seamlessly from prototype to volume manufacturing without changing partners.
Answers for engineering and purchasing teams planning prototypes, new product introductions, and production builds.
Circuits Central provides design, PCB assembly, and post-assembly services at our facility in Markham, Ontario, in the Greater Toronto Area. We support professional electronics projects from pre-assembly design through assembly, inspection, testing, and final product assembly. PCB fabrication and component sourcing are supported by our network of trusted partners.
Yes. Circuits Central offers a Canadian turnkey PCB assembly solution that coordinates bare PCB procurement, component sourcing, assembly, and the post-assembly services your project requires. Design, assembly, and post-assembly work take place at our Canadian facility, with trusted partners supporting PCB fabrication and component sourcing.
No. Circuits Central has no minimum order quantity for PCB assembly. We support single-board prototypes as well as larger builds for engineering teams, commercial product developers, and OEMs. You can start with the quantity your development stage requires and discuss subsequent builds as your product progresses.
Our standard PCB assembly turnaround is typically two weeks (10 business days), with expedited assembly available in as little as 24 hours for eligible builds. Assembly lead time begins when all required materials and approved files are ready. PCB fabrication, component procurement, and shipping are additional to that assembly window. We confirm the schedule for your specific project during quotation.
We typically provide a complete quotation within one business day of receiving the required files and project details. To help us quote accurately, include your build quantity, required delivery date, supply arrangement, and any special assembly or post-assembly requirements alongside your manufacturing documentation.
For consigned PCB assembly, where you supply the bare boards and components, provide a bill of materials (BOM) and an assembly drawing. For full turnkey pricing, also include Gerber fabrication files so we can quote bare PCB procurement alongside component sourcing and assembly. Include applicable specifications and process instructions for additional requirements, such as conformal coating.
Our assembly inspection process includes solder paste inspection, post-reflow solder joint inspection, manual visual inspection, and automated optical inspection (AOI). The solder paste inspection method depends on the build and may use dedicated inspection equipment, the stencil printer’s inspection system, or manual checks. X-ray inspection is used where required to examine hidden solder joints.
Yes. Circuits Central can perform electrical and functional testing using customer-supplied test fixtures and procedures. If you do not have a test procedure, we can help develop one for your product. Share your test requirements during quotation so we can define the test scope and identify the equipment, fixtures, and instructions needed.
Yes. Our box build services can extend PCB assembly into final product assembly, including enclosure integration, product-specific testing, labelling, and packaging. We work to your project’s assembly instructions and requirements. Tell us what you need delivered, whether an assembled board or a finished product, so we can quote the appropriate scope.
Yes. We can accommodate BOM revisions and assembly changes, subject to the stage of your order. Cost or delivery impacts may arise when significant work is already complete, such as components purchased against the original BOM or assembly already underway. Contact us promptly with the revised files so we can assess the change and its impact on your build.
A board arrives at assembly with its test strategy already decided. Not proposed, decided. Whatever electrical access the layout provides is the only access any test system will ever have, and no amount of process engineering on the manufacturing side adds a probe point that was never placed. Design for test is therefore a layout activity with a manufacturing consequence, and the window to get it right closes when the Gerbers are released. The cost of getting it wrong has moved. Component pricing and lead times have tightened through 2026 across microcontrollers, memory, and passive components, which changes the arithmetic on a failed board. A unit that fails final test...
