## FAQ

- Can one RFQ cover PCB, PCBA, procurement, and EMS? Yes. A single RFQ can cover bare boards, BOM procurement, SMT and through-hole assembly, inspection, functional test, box build, packing, and delivery, or be scoped to only the services you need.
- Do you support prototype, low-volume, and high-mix builds? Yes. Quick-turn prototypes, EVT and DVT builds, pilot runs, and repeat low-to-mid volume or high-mix programs can use the same engineering handoff before release.
- Is there an MOQ or standard lead time? MOQ and lead time are confirmed after file review. PCB process, panel use, component pack sizes, material availability, assembly complexity, fixtures, programming, and test scope all affect the quote.
- Can you procure components and manage alternates? Yes. Procurement can include BOM cleanup, manufacturer part number checks, lifecycle review, authorized distributor review, MOQ planning, incoming inspection, and customer-approved alternates.
- What PCB types, assembly processes, and tests can be reviewed? Rigid, multilayer, HDI, flex, rigid-flex, aluminum, copper-core, heavy-copper, and RF PCB requirements can be reviewed with SMT, THT, BGA, AOI, X-Ray, ICT, FCT, and first-article needs.
- What do I need to start an RFQ? Start with what you have. Gerber/ODB++ or a BOM is enough for an initial RFQ, and one or two core files are usually fine. If the design is still early, you can send no files and talk with an engineer first; Omini will confirm only the details needed for the next quote step.
