Prepare your quotation
Files and information we need
What Files Do I Need for a PCBA Quote?
To prepare an accurate PCB assembly quotation, send the available production files together with the required build quantity and any special assembly or inspection requirements.
Gerber Files
PCB fabrication data including copper, solder mask, silkscreen, board outline and drill information.
BOM
Component list including manufacturer part numbers, quantities and approved alternatives where applicable.
Pick & Place File
Component coordinate / centroid data used for SMT placement.
Assembly Drawing
Assembly drawings, polarity notes or special placement instructions where required.
Quantity & Special Requirements
Required build quantity together with any special soldering, inspection, testing or packaging requirements.
Not sure whether your production package is complete? Send the files you currently have and our team can review the available Gerber, BOM and assembly data before quotation.
Purchasing FAQ
Turnkey PCBA Services Frequently Asked Questions
Practical answers about files, schedule, engineering support, production coordination and confidentiality.
What files do you need for Turnkey PCBA Services?
For Turnkey PCBA Services, send Gerber or ODB++ data, BOM with manufacturer part numbers, pick-and-place or centroid file, assembly drawings, approved substitutions, quantity, programming files, and inspection or functional-test requirements.
What is the typical lead time for Turnkey PCBA Services?
Lead time depends on design maturity, complexity, quantity, material or component availability, testing scope, and how quickly engineering questions are resolved. We confirm the schedule after reviewing your files; urgent prototype or quick-turn options can be discussed where the required process and materials permit.
Which EDA tools and file formats are supported?
Gerber and ODB++ are the preferred neutral production formats. If your source data is in a native EDA tool, tell us the software and version; we will confirm compatibility or ask for a controlled Gerber/ODB++ export, drill data, drawings and other release files.
Can you handle an existing design or previous revision?
Yes. We can work from an existing design, production package or previous revision. We first check completeness, revision control and the requested scope, then identify any missing data, manufacturability risks or changes that need your approval before work begins.
Do you provide signal integrity and power integrity analysis?
Yes, SI/PI analysis can be coordinated when manufacturing or assembly risk depends on controlled impedance, return paths or power integrity. It is a separate engineering scope and requires suitable design data, stackup information, models and acceptance criteria.
Can you coordinate fabrication and assembly?
Yes. Excel Circuit can coordinate fabrication, component sourcing, PCB assembly, inspection, testing and related box-build work as one project. The quotation states which stages are included, which materials are consigned, and the approvals needed before production.
How is design confidentiality protected?
Project files are limited to personnel and qualified partners who need them for quotation and delivery. Excel Circuit uses reasonable technical and organizational safeguards, does not publish customer designs without permission, and can work under a mutually agreed NDA. Your signed NDA or project agreement controls where it provides specific protections.
Final scope, price and lead time are confirmed after engineering review of your current files and requirements.
