Frequently Asked Questions
PCB & Electronics Manufacturing FAQs
What information is required for a PCB assembly quotation?
To provide an accurate quotation, we typically need your Gerber files, BOM (Bill of Materials), assembly drawings, target quantity, and any specific programming or testing requirements. Even if your files are incomplete, you are welcome to send them over—our team will review them and help identify any missing details.
Can you support prototypes and repeat production?
Yes. Early builds can be used to verify manufacturability, materials and testing before the product moves into repeat production. Build records and approved revisions are retained to improve consistency.
How do you manage component availability risks?
We review availability, lead time, lifecycle status and possible alternatives during BOM analysis. Any substitution requiring technical approval is communicated before purchasing.
What inspection and testing methods are available?
Available processes include SPI, AOI, X-ray inspection, flying probe, ICT and functional testing. The appropriate combination depends on board design, component type and product risk.
Can you develop a custom functional test fixture?
Yes. Fixtures and test procedures can be developed from your functional requirements, test points, firmware and acceptance criteria.
