PCB Earnings Surge

One of China's largest PCB and packaging substrate makers has just reported one of the strongest quarters in the industry. Shennan Circuits said its third-quarter 2026 revenue reached RMB 10.478 billion, up 66.29% year on year, while net profit attributable to shareholders rose 94.42% to RMB 1.878 billion. The company attributed the jump to AI computing infrastructure investment and product upgrades that lifted demand across its PCB, packaging substrate and PCBA businesses - a signal that high-end electronics assembly capacity is being consumed as fast as it is built.

Industry Update

According to the company's investor-relations disclosure on October 23, 2026, third-quarter revenue rose 66.29% year on year to RMB 10.478 billion, with recurring net profit up 102.78% to RMB 1.858 billion. Management linked the growth to AI compute infrastructure investment and product iteration: demand for AI accelerator cards, servers and related products kept rising, high-speed switch and optical module revenue grew noticeably, and orders for application-processor and memory packaging substrates were released quickly. At the same time, capacity at its Guangzhou and Nantong production bases continued to ramp, supporting both revenue and profit growth. The results echo the broader equipment picture - from Mycronic's raised 2026 outlook to the new platforms shown at NEPCON Asia 2026 - in which AI infrastructure is the single biggest driver of electronics manufacturing investment.

What It Means for SMT Lines

• AI accelerator and server boards combine high layer counts, high-speed materials and dense fine-pitch components, so placement accuracy, reflow consistency and inspection coverage all come under pressure at once.
• PCBA revenue growth means the assembly side - printing, placement, reflow, wave soldering and inspection - is running at high utilization, which raises the value of every uptime hour.
• Packaging substrate volume growth pulls precision requirements upward across the supply chain, including tighter warpage control and cleaner handling.
• With capacity ramping at multiple bases, equipment that can be installed, qualified and ramped quickly is worth more than equipment with a higher theoretical speed.
• Mixed product structures favor flexible lines: fast programming, feeder flexibility and reliable traceability matter as much as throughput.

Outlook

The third-quarter numbers suggest AI infrastructure demand is still accelerating rather than peaking, and PCB and PCBA capacity additions will continue into 2027. That is good news for equipment suppliers - provided they can deliver complete, stable lines rather than single machines. HWGC, a China SMT machine manufacturer, supplies four-head to twelve-head pick and place machines, reflow soldering ovens, solder paste printers, wave soldering systems, PCB loaders, conveyors and AOI/SPI inspection equipment, giving factories building or expanding SMT capacity a single source for the core line.
