Our Working Process



Before production, our engineer will check if there is any error in PCB Gerber and BOM, to avoid mistakes.



We will send customer engineering questions about the files and recommend the best solution.



“Quality Comes First” is our motto which is engraved in every staff of Viasion in our manufacturing.



Our quality control team will test PCBs by AOI, ICT, FCT etc., to make sure high-quality products.

Our Factory Show


1. What is your lead time?

The lead time for different PCB may be different, our normal lead time is 1-3 weeks for PCB bare board, and 2-8 weeks for PCB assembly.

2. What is the minimum requirement for the order?

We don’t have min. order quantity. We welcome orders as low as 1 piece since we focus on Small to Medium Volume Production.

3. What you can do for us?

We provide custom PCB bare board manufacturing, PCB assembly, components sourcing, IC programming, cable assembly, box build assembly, complete electronics assembly and storage. 

4. How do you control quality in our production?

1). Our experienced engineers will do DFM (Design for manufacturing) and DFM (Design for assembly) before production, to avoid design errors

2). We make sure quality management systems like ISO9001:2016 are implemented in our production;

3). All our PCB bare boards are 100% open/short tested, AOI inspected and visually inspected;

4). All our PCB assembly will be 100% AOI inspected, ICT testing and FCT if needed; 

5). Before mass production, we will produce a small production first for approval. 

5.Can you arrange the shipping for my order?

Yes, we can arrange shipping for you, by sea, by air or by EXPRESS. 

6. What files do you need for production for our PCB?

We need Gerber files for PCB Manufacturing, Gerber files + BOM for PCB Assembly,  and Gerber files + BOM + drawing for the other material for Electronic Manufacturing Services.
