Q1.What is needed for PCB PCBA quotation?
PCB(printed circuit board): Quantity, Gerber file and Technic requirements(material,surface finish treatment, copper thickness,board thickness ,...)
PCBA(printed circuit board assembly): PCB information, BOM, (Testing documents...)
Q2. What file formats do you accept for PCB PCBA production?
Gerber file: CAM350 RS274X
PCB file: Protel 99SE, P-CAD 2001 PCB
BOM: Excel (PDF,word,txt)
Q3. Are my files safe?
Your files are held in complete safety and security.We protect the intellectual property for our customers in the whole process.. All documents from customers are never shared with any third parties.
We are willing to sign NDA effect by customer side local law and promising to keep customers data in high confidential level.
Q4. MOQ?
There is no MOQ (PCBA shenzhen).We are able to handle Small as well as large volume production with flexibility.
Q5.Shipping cost?
The shipping cost is determined by the destination, weight, packing size of the goods. Please let us know if you need us to quote you the shipping cost.
Q6. What service do you have?
A: We mainly focus on PCB+Assembly+Components sourcing service. Additionally, we can also provide programming, testing, cables, enclosure assembly service.
Q7. Can we inspect quality during production?
Yes, we are open and transparent on each production process with nothing to hide. We welcome customer inspect our production process and check in house.
Q8. No PCB file/Gbr file, only have the PCB sample,can you produce it for me?
Yes,we could help you to clone the PCB. Just send the sample PCB to us, we could clone the PCB design and work out it.
Q9. Which countries have you worked with?
US, Canada, Italy, Germany, Czech Republic, Australia, Japan, and so on.
Q9. What is your testing policy and how you controle the quality?
For sample, usually tested by flying probe; for PCB Volume over 3 square meters, usually tested by fixture, this will be more faster. Due to there’s many steps to PCB production, we usually do inspection after every step.
