Why Choose LZJPCB as Your PCB Contract Manufacturer
Why is LZJPCB considered one of the best Chinese PCB manufacturers?
LZJPCB combines Chinese cost advantage (40-60% lower than
US/EU) with Western grade quality certifications — ISO 9001,
IATF 16949 (automotive), ISO 13485 (medical), and ISO 14001.
With 20 years of experience, 4 factories across China and
Indonesia, 58,000 m²/month capacity, and a 100% on time
delivery record, we serve 1,600+ customers in 50 countries.
Unlike typical low cost Chinese fabricators, every order
includes free engineer level DFM review and 24/7 English
project management.
How does LZJPCB handle US tariffs on Chinese PCBs?
LZJPCB operates a dual factory strategy: 3 factories in
China (primary production, 24,000 m²) and 1 factory in
Indonesia (4,000 m², tariff safe hub). U.S. customers can
route orders through our Indonesia facility to avoid
Section 301 tariffs on Chinese electronics imports, while
maintaining LZJPCB’s quality standards and engineering
support. This dual footprint also provides supply chain
resilience against geopolitical and logistics disruptions.
What makes LZJPCB a reliable custom PCB manufacturer?
Every custom PCB order at LZJPCB goes through a standardized
9 stage quality process — from incoming material inspection
(IQC) to outgoing quality control (OQC) — including 100%
AOI, electrical testing, and X-Ray inspection for BGA
components. We maintain a 98% production yield rate and
sign NDAs before any Gerber file review to protect your IP.
What industries does LZJPCB specialize in?
LZJPCB manufactures PCB for 4 major industries: Automotive
(IATF 16949 certified; EV chargers, truck lights, forklifts),
Medical (ISO 13485-compliant; CGM devices, massagers,
diagnostic equipment), Consumer Electronics (massage guns,
audio amplifiers, party boxes), and Industrial (elevator
controls, power electronics, automation). Each industry has
dedicated engineering teams and material libraries.
How fast can LZJPCB deliver PCBs and PCBA?
LZJPCB offers the fastest turnaround in the industry:
24 hour quick turn for 1-4 layer PCB prototypes, 48-72
hours for 6-8 layer boards, 5-7 days for HDI / rigid-flex
prototypes, and 7-15 days for production volume up to
100,000+ units. Global shipping via DHL / FedEx Express
adds 3-5 days to reach 50+ countries.
Does LZJPCB provide one stop PCB fabrication and assembly services?
Yes. LZJPCB is a true one stop PCB and PCBA manufacturer.
Under one roof, we handle PCB fabrication (1-40 layers,
all materials), component sourcing (BOM management with
1M+ part database), SMT and through hole assembly (down to
01005 and 0.25mm pitch BGA), functional testing (AOI,
X-Ray, ICT, FCT), and box-build integration — eliminating
coordination overhead across multiple vendors.
Is LZJPCB suitable for both prototypes and volume production?
Absolutely. LZJPCB serves 3 customer segments equally well:
hardware startups needing 1 piece prototypes with 24h turn, OEM/ODM manufacturers requiring volume production
(58,000 m²/month capacity with IATF 16949 automotive
quality), and contract manufacturers needing full turnkey
EMS with BOM management. No MOQ for prototypes.
Can I visit or audit the LZJPCB factory?
Yes. LZJPCB welcomes factory audits and visits at all
4 facilities (3 in China, 1 in Indonesia). Book an
in person tour or a virtual video walkthrough — we have hosted procurement teams from Germany, USA, Japan, Korea,
and 20+ other countries. Transparency is central to our
20-year customer relationships.
