Industrial PCB Assembly Services
Precision-Built for Harsh Environments and Heavy-Duty Performance
Temperature extremes, vibration, shock, humidity, chemical exposure, voltage stress, and EMI are some of the normal operating conditions where industrial PCBs have to run 24/7. At BESTProto, we specialize in building industrial-grade PCBs designed to thrive in that environment.
Quality Standards & Certifications
Reliability starts with the standard we build to. Every industrial PCB is assembled up to IPC Class 3, the same level trusted by aerospace and defense manufacturers, and backed by:
- AS9100:2016 Certified: The same rigorous process controls and traceability standards used in mission-critical aerospace work, applied to every industrial build we handle.
- ISO 9001:2015 Certified: A documented quality management system covering every stage of assembly, from incoming inspection to final test.
- IPC-A-610 Class 2 & Class 3 Certified: Workmanship standards built for reliability in demanding industrial environments.
- IPC J-STD-001 Certified: Consistent, reliable interconnections for mission-critical builds.

Frequently Asked Questions
About Our Industrial PCB Assembly Capabilities
What IPC class do industrial PCB assemblies require?
Industrial PCB assemblies are typically built to IPC Class 2 or Class 3 workmanship, depending on the application’s requirements. Most industrial jobs are specified to Class 2 workmanship, since it reliably meets the needs of most applications at a lower cost, with Class 3 available for higher-risk or mission-critical builds.
Do you recommend cleaning boards that used no-clean solder paste during assembly?
BESTProto uses no-clean flux by default, and for most everyday industrial boards, the leftover residue is safe to leave in place. We recommend cleaning when a board is headed for a humid or high-reliability environment, has tightly spaced or low-standoff components, or will be conformally coated, since leftover residue can affect coating adhesion. See our full guide for more detail.
What inspection does BESTProto perform on industrial PCB assemblies?
Every build goes through a mandatory first article inspection, 100% Automated Optical Inspection, and X-ray inspection of all leadless components to check for voids and other hidden defects.
Do you offer conformal coating service?
Yes, we provide conformal coating and potting to protect assemblies from moisture, dust, and chemical exposure common in factory floors and outdoor industrial environments.
What's your typical turnaround time for industrial PCB assembly?
Industrial PCB assemblies typically ship in 5, 10, or 20 business days, with 24-hour rush service available on request.
Do you manufacture in the United States?
Yes, all assembly takes place at our South Elgin, Illinois facility, supporting shorter lead times, easier collaboration, and a secure domestic supply chain.
