PCB Assembly and Electronics Manufacturing FAQs
Where does Circuits Central provide electronics manufacturing services?
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.
Do you offer full turnkey PCB assembly?
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.
Is there a minimum order quantity for PCB assembly?
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.
What are your standard and expedited PCB assembly lead times?
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.
How quickly will I receive a PCB assembly 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.
What files do I need for a consigned or turnkey PCB assembly quote?
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.
What inspection is included with PCB assembly?
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.
Can you perform functional testing using our fixtures and procedures?
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.
Do you offer box build and final product assembly?
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.
Can you accommodate BOM revisions or engineering changes after an order is placed?
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.

Circuit Board Tests
Design for Test: What Your CM Needs Before It Can Test Your Board
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...
