How does LZJPCB's MOQ compare to other PCB manufacturers?
Unlike many PCB manufacturers that require 5-10 pieces for prototype orders, LZJPCB accepts 1 piece. LZJPCB's mass production MOQ is 50 pieces (vs. competitors' 100 pieces). For PCBA prototypes, many factories require 5-10 pieces, while LZJPCB accepts 1 piece.
How do I get a quote from LZJPCB?
Send your Gerber files and Bill of Materials (BOM) via our official email (Jayden@LZJPCB.com) or WhatsApp (+86 133-1654-3659). You will receive the quotation within 12 hours. No hidden fees. No minimum order requirement. We will sign an NDA before reviewing the documents upon your request.
What PCB materials does LZJPCB support?
LZJPCB supports all mainstream PCB substrates: FR4 (standard and high-Tg up to 180°C), Rogers (RO4350B, RO4003C, RT/Duroid 5880), Ceramics (Al₂O₃ and AlN), Aluminum MCPCB (thermal conductivity 1-9 W/mK), and Polyimide for flexible circuits.
What is the maximum layer count LZJPCB can manufacture?
LZJPCB produces PCBs from single layer to 40 layers, including any-layer HDI designs with stacked microvias, rigid-flex structures, and high-frequency Rogers or ceramic substrates. Minimum trace width and spacing is 3 mils / 3 mils (75μm / 75μm).
Does LZJPCB provide free DFM review?
Yes, every order includes a free engineer-level DFM review, completed within 2 hours after Gerber file upload. Our engineers check trace width, spacing, drill hole sizes, annular rings, impedance control, panelization plan, and solder mask clearance -- flagging issues before production to save costs and time.
What certifications does LZJPCB hold?
LZJPCB holds 7 international certifications: ISO 9001 (Quality Management), IATF 16949 (Automotive), ISO 13485 (Medical Devices), ISO 14001 (Environmental Management), UL (USA and Canada Safety), RoHS (Restriction of Hazardous Substances), and REACH (EU Chemical Safety).
Does LZJPCB offer NDA protection for IP-sensitive designs?
Yes. LZJPCB will sign an NDA before reviewing any Gerber files. Files are stored on encrypted, dedicated servers with access restricted solely to the designated engineering team.
