Frequently Asked Questions
Frequently Asked Have
Any Question?
How do you order components for Turn-Key PCB orders?
We help businesses bring ideas to life in the digital world designing & implementing the technology tools that they need to win. We help business bring ideas to life in the digital wor
What is the lead time on a turn-key order?
The overall project Lead Time is the sum Parts Procurement lead time and PCB Assembly lead time. However, we try to shorten the time line by streamlining our PCB Assembly Process. For instance, once we receive your Gerber Files for PCB Fabrication and BOM for PCB Assembly, we will start to prepare the stencil for your board and complete the fabrication concurrently with the parts procurement process.
Is there a minimum order size for turn-key PCB orders?
No. We have no restrictions on your order size; however, larger orders are more cost effective. If you discuss your target price with your KeepBestPcba account manager, we can work with you to find a good solution for your specific needs in cost reduction.
What do I need to send for a turn-key PCB order?
Bill of Materials, complete information in excel format. This document should include manufacturer names, part numbers, Reference Designators, component descriptions, and quantities. Gerber Files Centroid Data (AKA Pick and Place or XY-Coordinate Data) Other requirements or assembly instructions if applicable
Are my PCB Design Files safe when submitting them to you for manufacturing?
We respect customer's copyright and will never manufacture PCBs for someone else with your design files unless we receive written permission from you, nor we'll share these files with any other 3rd parties. At your request, we can sign an NDA for extra security.
