Engineering & Quality Details

Supporting Detail

How We Engineer and Verify Every Build.

Behind the four pillars sits the day-to-day discipline. Our NPI team optimizes your product for high-yield output, and a fully documented quality pipeline verifies every batch from incoming components to outgoing shipment.

Engineering Capability

We don't just Assemble. We engineer your product to scale.

Our NPI team runs a thorough DFM review on every project before it touches the production floor, so your product is built for high-yield output from day one.

DFM Review

Design-for-Manufacturing analysis to catch footprint errors, yield risks, and thermal issues before production begins.

BOM Validation & Sourcing

Component cross-referencing, lead-time risk flagging, and alternative sourcing across Vietnam and Southern China.

Prototype & Pilot Run

First Article Inspection samples within 5–7 business days when components are on hand. 100% inline inspection on every prototype.

Production Readiness

Documented solder profiles, process parameters, and test procedures handed over before mass production launch.

Common Questions

Frequently Asked Questions

Answers to the most common questions from procurement teams, hardware founders, and engineering leads evaluating Lian Tech as a manufacturing partner.

How do you support BOM sourcing and component shortages?

Our procurement team in Vietnam and China sources directly and finds cross-reference alternatives when shortages hit. We keep your program moving while staying on budget.

What is your quality control process for Assembly?

Our facility holds ISO 9001:2015 certification. Every production run goes through 3D SPI, Inline AOI, and 3D X-Ray for complete inspection coverage across all Assembly processes.

Do you have a Minimum Order Quantity (MOQ) for new projects?

We work across high-volume mass production and small-to-mid-size pilot runs (NPI) alike. Whether you are launching a pilot or scaling to millions, we are the team to support your growth.

Can you provide DFM feedback before production?

Yes, always. Every project gets a full DFM review from our engineering team before anything goes to the production floor. We catch footprint errors, yield risks, and thermal issues early so they don't become expensive problems later.

What is your standard lead time for PCBA prototyping (NPI)?

For projects with components on hand, our rapid prototyping team delivers First Article Inspection (FAI) samples within 5–7 business days. Mass production timelines are customized based on BOM complexity.

How do you ensure our designs and IP remain secure?

IP protection is taken seriously here. We operate under strict mutual NDAs and our engineering servers are air-gapped from public networks. Access to customer design data is limited to essential personnel, and every access is logged.

What is your experience with global exports?

Over 90% of what we ship goes to international markets. We handle global logistics, customs documentation, and export-ready packaging for customers across Asia and North America.
