Q:Are my design files safe when I submit them to you for manufacturing?
We respect customer's copyright and will never manufacture PCBs for someone else with your files unless we receive written permission from you, nor we will share these files with any other 3rd parties.
Q:Do you check my manufacture data?
Yes. We check your artwork based on documents you sent to us. We do provide some suggestions to you, free of charge if you need, on our design rules such as increasing clearance, trace width or pad size to decrease cost or make your ordered boards within our manufacturing capability. But it is still up to you to make decision.
Q:Do you produce only prototypes or I can order production quantities from you too?
We can manufacture PCBs in any volume.
Q:Can you assemble and solder my prototype boards?
Yes, we can assemble and solder your prototype boards.Thers is no minimum order quantity.
Q:Do you test the bare PCBs before dispatch?
Yes. All prototypes and medium volume order PCBs are tested using flying probe testers. Custom designed and manufactured fixtures(also called bed of nails) are used for large production runs.
Q:Can you order electronics components only?
Yes, we can. Puhong provides a unique component sourcing service to support our customer's needs and to compliment our in-house PCB manufacture & assembly services. 
Q:What do you require in order to produce an assembly quotation ?
Bill of materials(BOM) detailing the components to be fitted to the PCB with the manufacturers parts numbers and the components suppliers' parts number(e.g.Farnell,RS,Digi-key).PCBA sample photos if possible. By allowing us to see the product pictures it will help us to give you the quotation faster. In addition to the above, we would need details of approximate order volume and a desired delivery schedule.
