Purchasing FAQ
PCB Manufacturing Frequently Asked Questions
Practical answers about files, schedule, engineering support, production coordination and confidentiality.
What files do you need for PCB Manufacturing?
For a PCB Manufacturing quotation, send Gerber or ODB++ data, NC drill files, fabrication drawing, layer stackup, material and copper requirements, surface finish, controlled-impedance details, quantity, and required delivery date.
What is the typical lead time for PCB Manufacturing?
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.
