1.Which type of PCBs do you expert in?
We are specialized in producing Singe-side PCB,Double-side PCB, Multilayer PCB,Aluminium PCB,Spray Tin PCB,Immersed Gold PCB, etc.
2.What is your Lead time?
Lead time is usually punctual here, usually 5-10 days for PCB sample, 10-15 days for mass production. For some special situation, we can also advise customer in advance to avoid any inexpectation or loss at customer side.
3.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.
4.What is your package?
With Inner vacuum package and out carton.
This is depend on customer, sometimes we ship through our forwarder, who is also the agency of DHL, TNT, UPS, Fedex, and so on. Our forwarder can provide too much better freight cost than we get directly from those express enterprise.
6.What is your produce ability?
Our ability is average 30,000 square meters per month.
7.I only have the pcb sample, not pcb file, can you produce it for me?
Yes, we can copy file based on your sample, this file names gerber, and production then is accorded to gerber file.
8.Can you design gerber file?
We can design gerber file if customer can provide us schematic, schematic sample can also be provided if customer want.
9.What kind of PCB file format can you accept for production? What CAM software do you use?
We accept Gerber file for production. CAM350, GENESIS, UCAM, GC-CAM, V-2000.
10.Will you allow me to put several part number together into one panel?
Yes, this is usually happen in we factory, this way can help customers reduce some cost and to a certain degree, it can help reduce some assembly cost.
11.What is your minimum order quantity?
We have no limitation on MOQ, prototype, medium volume and large volume are all acceptable.
12.Will RoHS Lead-Free Custom Spec. Boards be marked with lead-free symbol?
Yes, can, but need customer to specify this requirement in file.
13.Are my design files safe when I submit them to you for manufacturing?
Any customer’s file will be protected very well here in our factory and we will not let any third party know. We can sign NDA with you.
Comparison of Competing Products
