As a 20-year veteran in industrial electronics, we focus on solving pain points for brand owners, procurement engineers, and hardware engineers—especially when it comes to PCB Assembly (PCBA), the core of motor control units. Below, we’ll highlight how our PCBA capabilities drive reliability, and how we simplify your supply chain with integrated solutions.
For motor control units, PCBA quality directly determines performance. We specialize in multi-layer PCBA (4-8 layers) and thick copper board assembly—critical for high-power motor applications—and prioritize two non-negotiables: precision and zero defects.
Thick copper boards (1.0-2.0mm, customizable) are essential for withstanding high currents and heat in motor control. We use Laser Direct Imaging (LDI) for etching, controlling line width/spacing to ±0.03mm—50% more accurate than traditional exposure—avoiding uneven current distribution.
For welding, our 10-zone intelligent reflow oven stabilizes peak temperatures at 235±3℃, tailored to thick copper’s fast heat conduction. This ensures ≥95% pad wettability. Post-welding, AOI + X-Ray dual inspection (X-Ray for BGA 焊点) keeps cold solder joints below 0.01%.
A servo motor customer once faced “current overload board burnout” with another supplier. We optimized their PCBA’s copper layer distribution and heat-dissipation holes—now, 3 months of mass production show zero defects.
We source PCBs from trusted partners but enforce our own quality checks: incoming inspections for material compliance, in-process monitoring of soldering parameters, and 100% functional testing post-assembly (e.g., motor start-stop response ≤100μs, load current fluctuation ±0.5%). This eliminates risks of field failures.
Instead of juggling PCBA suppliers, assemblers, and testers, we integrate PCBA with supporting services to save you time and cost.
We don’t just do PCBA—we assemble it with custom wiring harnesses (simplified: 200℃ fluoroplastic wires for high temps, ultrasonic welding for durability) and enclosures (customer-designed; we assist with tweaks if needed). Post-assembly, we conduct full functional tests, so you receive ready-to-install units.
A customer previously struggled with “wiring harness contact issues” during self-assembly. Our one-stop process cut their finished product defect rate from 5% to 0.3%.
Hardware engineers often face design-to-production gaps. Our 5 senior engineers offer free DFM analysis for PCBA: optimizing layouts for easier welding, adjusting heat-dissipation paths, or fixing assembly conflicts. One customer’s PCBA couldn’t fit their enclosure—we revised the board’s edge design, boosting assembly efficiency by 30%.
For export, we assist with ROHS/FCC certifications: pre-testing (e.g., ROHS heavy metal checks) to avoid rework, and helping prepare BOMs/process docs. A European-market customer got ROHS 2.0 certification in 20 days—half their expected time.
Send your PCBA specs (layers, thick copper needs, GERBER files) to sales@fumatech.com or message us at www.fumatech.com. Our PCBA and engineering teams respond within 24 hours. For us, reliability means delivering PCBA that keeps your motors—and your production lines—running.
