Frequently Asked Questions (FAQs)
How we ensure the quality of circuit board manufacturing and assembly?
We choose top sheet suppliers to ensure stable performance (general FR-4). During the manufacturing process, automatic copper plating lines and high-speed drilling machines (brand:TMAX) to make accuracy and fast delivery guaranteed. All printed circuit board will be detected by advanced automatic flying probe machines (or test frame ) at subsequent stages to make sure each PCB is OK from inner circuits to outside shape.
 
How long will you get our quotation of PCB manufacturing and assembly?
In general, PCB sample is delivered in 24~72 hours (urgent order less than 24 hours). Volume production can be completed in 7 working days. If for subsequent PCB assembly and test requirements, the lead time could be less than 15 days.
 
What kind of files you have to send us to get quotation?
You have to send us PCB design files (gerbers or .pcb acceptable), Bill of Materials (BOM), Quantities to make quote and other technical requirements (.step/.txt/.xls files acceptable)
 
What payment methods we can support?
We accept T/T, L/C, West Union as payment methods. For prototype order, you have to make 100% payment in advance, but for mass production 70% payment in advance and 30% payment before delivery.
 
What measures we take to avoid counterfeit components?
Procurement only from manufacturer or big general agent
Original quality certificate of component can be issued (if necessary)
Inspections of shape, silkscreen and conductivity attributes in incoming quality control
Strong responsibilities and perspectives of long-term relationship
 
What measures we take to protect clients IP and confidentiality?
Sign NDA (Non-disclosure Agreement)
Using number code in stead of client name during manufacturing process
Separate assembly workshop and taking photo is NOT allowed
Documents of engineering process are archived and reserved
