What is the minimum order quantity (MOQ) at LZJPCB?
LZJPCB has no minimum MOQ for PCB prototypes — orders start
at 1 piece. For PCBA (assembly) orders, MOQ starts at 1
piece for prototypes and 50+ pieces for production runs.
We serve everyone from solo hardware developers to Fortune
500 procurement teams.
How do I get a quote from LZJPCB?
Upload your Gerber files and BOM through our instant quote
portal — you’ll receive a transparent quote within 4 hours
(most quotes in under 1 hour during business days). No
hidden fees, no minimum commitment, and NDA signed before
file review if requested.
What PCB materials does LZJPCB support?
LZJPCB supports all major PCB substrates: FR4 (standard and
