A: The typical value of our FR4 Tg140 substrate dielectric constant is 4.6, FR4 Tg170 substrate dielectric constant is 4.2.
A: Usually it takes 3-5 working days for international shipping.
A: Our standard lead time for stencils is 1-2 working days after we have confirmed the stencil production file.
A: Our standard lead time for PCB assembly orders is around 3-4 weeks, PCB manufatcuring, component sourcing, and assembly will be finished within the lead time.
A: There is no specific requirement on PCB design software. We can precisely manufacture your boards as long as you provide us with PCB design files in Gerber RS-274X format (most preferred, 274D format is not accepted), files in *.PCB/DDB (Protel, please inform your Protel program version) or *.BRD (Eagle) formats.
A: Yes. Our Standard PCB service offers impedance control option. You may submit the order on Instant Quote page, make a note “”please control impedance within **”” at the Special Requirement Note section. Then submit the order, upload files and release the payment. Your requirement will be known as manufacturing starts.
A: We manfuacture prototype boards based on default layer stack up. If you need custom layer stack up, please switch to our Standard PCB service. Feel free to request our standard layer stackup , don’t forget to tell us your pcb thickness and layer count.
A: Min 50*50 | Max 310*410mm
A: With years’ experience in this industry, we have built a reliable components sourcing channel. All components will be purchased from reputable agents like DigiKey and Mouser. Additionally, we have a quality control department which verifies high quality of parts. You have our words on the quality of the parts we use.
A:If you’re looking for Prototype service, the min order quantity of PCBs is 1 pcs , there is no min order quantity limit .
A: Yes, we can work with single PCB files and manufacture boards in panels.to meet your panel requirements, you can send the panel requirements to us, and we will confirm the panel method with you before buliding PCB.
We’ve shipped PCB boards to customers from over 100 countries in the past 15 years and the number keeps rising each year. Surely we can ship boards to your country.
