Industrial PCBs Manufacturing & PCBA Services

Industrial PCBs are specialized circuit boards engineered to thrive in harsh operating conditions—think extreme temperatures, heavy vibrations, high humidity, and corrosive environments. Unlike commercial PCBs designed for short lifespans (1-3 years) in stable settings like offices or homes, industrial PCBs are built for longevity, typically lasting 5-15+ years. They adhere to strict standards like IPC Class 3, ensuring reliability in critical applications where failure could lead to downtime, safety risks, or financial losses.

What is an Industrial PCB?

Industrial PCBs are engineered for extreme operating environments, delivering consistent performance under:

• Temperature extremes (-40°C to 150°C)
• High vibration (up to 5Grms)
• Humidity/IP67-rated contamination
• Electromagnetic interference

Rigorous testing and inspection for PCB

To ensure that your PCBs are functioning optimally, we can provide comprehensive testing and inspection throughout the design and manufacturing process.

Before manufacturing:

DFM & DFA checks

BOM checks

Special stack-up help / NPI review

Component engineering assistance and procurement

After manufacturing:

Functional inspections

Thermal cycling tests (TCT)

Thermal shock tests (TST)

Temperature-humidity bias tests (THB)

AOI report or visual inspection report

Flying probe or in-circuit testing report

Manufacturing Industrial PCBs: Key Steps & Considerations

Critical Steps:

• Design & DFM Review: Engineers use Altium to create Gerber files, followed by Design for Manufacturability checks to verify trace widths, hole sizes, and material compatibility.
• Cleaning & Drilling: Panels are cleaned to remove contaminants, then drilled for component placement and layer connections (using CNC machines for accuracy).
• Electroplating & Etching: Copper is deposited in holes to connect layers; unwanted copper is removed via alkaline etching.
• Inspection & Testing: Automated Optical Inspection (AOI) and X-ray detect flaws. Electrical tests (ICT, flying probe) ensure no shorts or opens.
• Coating & Finishing: Solder masks protect copper, while conformal coatings (epoxy, acrylic) add moisture/corrosion resistance.

FAQ

Q: How is an industrial PCB different from a commercial one?

A: Industrial PCBs handle wider temperatures (-65°C to 150°C), vibrations (10-500Hz at 10G+), and have longer lifespans (5-15+ years). They also meet stricter standards like IPC Class 3.

Q: What materials are best for high-heat applications?

A: Ceramic substrates (Al2O3) or high Tg FR-4 (Tg >170°C) work best for sustained high temperatures.

Q: Do industrial PCBs require special testing?

A: Yes—tests include burn-in (long-term operation), thermal cycling, vibration/shock trials, and corrosion resistance checks.
