Frequently Asked Questions
Frequently Asked Have
Any Question?
How do you order components for Turn-Key PCB orders?
Start with the approved BOM and define who purchases each line. Agree acceptable sources and customer approval before any component substitution. Compare material supply models.
What is the lead time on a turn-key order?
Timing depends on engineering review, material availability, fabrication, assembly and the test plan. Ask for the schedule applicable to your released project; a generic turnaround is not a production commitment.
Is there a minimum order size for turn-key PCB orders?
Discuss the prototype, pilot and volume quantities you need. Setup, materials and test requirements affect batch economics and the agreed order conditions.
What do I need to send for a turn-key PCB order?
Prepare PCB data, a BOM with manufacturer part numbers, placement data, drawings, quantities, delivery country and test requirements. Use the PCBA RFQ checklist.
Are my PCB Design Files safe when submitting them to you for manufacturing?
Before sending confidential files, agree NDA and file-transfer arrangements with sales. The enquiry form accepts a project description; sales coordinates the subsequent file handover.
