IN Brief:
- Semiconductor Back-End Solutions revenue increased 99% to $49.0 million during fiscal 2026.
- Total backlog reached $24.2 million, compared with $11.0 million a year earlier.
- Expanded Malaysian capacity and automotive production burn-in work accompany continuing AI-related reliability-test demand.
Trio-Tech International increased revenue from its Semiconductor Back-End Solutions operation by 99% during fiscal 2026 as reliability testing demand grew across AI, high-performance computing, and automotive semiconductor programmes.
Segment revenue reached $49.0 million for the year ended 30 June, compared with $24.7 million in fiscal 2025. Total company revenue rose 72% to $62.6 million, making semiconductor back-end work the clear majority of the group’s activity.
Year-end backlog reached $24.2 million from $11.0 million a year earlier. Approximately $19.8 million of the total related to Semiconductor Back-End Solutions, with about $4.4 million attributable to the company’s Industrial Electronics operation.
The back-end business includes semiconductor reliability testing and production burn-in, processes performed after device fabrication to identify early failures and establish whether parts can withstand the electrical and thermal conditions expected in service.
Burn-in deliberately places semiconductor devices under controlled stress for a defined period. Components that fail during this stage can be removed before they reach systems where access, replacement, or field failure is considerably more expensive.
AI accelerators and high-performance computing devices are contributing to the increased workload. Such components combine high device value with substantial power density and increasingly complex packaging, raising the cost of allowing latent defects to escape into finished systems.
Automotive semiconductor testing is developing alongside that demand. Trio-Tech recently secured a three-year production burn-in contract with another global integrated device manufacturer serving an electric-vehicle application, representing its second EV semiconductor production burn-in customer.
The contract carries minimum billings of about $4.7 million over its term and can scale to approximately $6 million. Moving from qualification activity into production burn-in places greater emphasis on throughput, repeatability, traceability, equipment utilisation, and process control.
Trio-Tech is also adding physical capacity in Malaysia. Its expanded footprint in Perai, Penang includes about 104,000 square feet of additional space, where installation of system-level and electrical test capability is being phased in to support higher production volumes.
Capacity alone does not determine test output. Reliability operations also depend on specialist equipment, validated procedures, fixtures, trained engineering staff, calibration, and sufficient utilisation to absorb the cost of new production infrastructure.
The company’s fourth-quarter figures show semiconductor demand remained elevated at the end of the year. Back-End Solutions revenue was $12.1 million for the quarter, about 85% higher than the $6.6 million recorded in the corresponding period of fiscal 2025.
The rapid revenue increase has not produced the same movement in margins. Fiscal-year gross margin fell to 17% from 25%, while Trio-Tech recorded a $204,000 operating loss compared with operating income of $254,000 a year earlier.
Part of the change reflects the economics of higher-volume semiconductor testing as well as increased corporate expenses. Expanded test capacity requires investment before new equipment reaches steady utilisation, while high-volume programmes can carry different margin characteristics from lower-volume engineering work.
The company enters fiscal 2027 with $7.9 million of previously announced burn-in board-related orders still to be delivered and a further first-quarter purchase order worth about $1.5 million. It expects production volumes in the expanded Malaysian facility to rise progressively from the second quarter of fiscal 2027.
The growth shows how increased semiconductor demand propagates beyond wafer fabrication. AI accelerators, automotive devices, and high-performance computing silicon also require packaging, electrical test, burn-in, and reliability capacity before finished components can move into systems.
Trio-Tech’s results place numbers against that less visible part of the electronics industry: back-end revenue has almost doubled, the backlog has more than doubled, and additional floor space and test capability are being installed to handle the next group of customer programmes.
