Aehr Test Systems Receives Follow-On FOX-XP Wafer-Level Burn-In Order from Major Silicon Photonics Customer for Hyperscale Data Center Optical Interconnects

Aehr Test Systems (NASDAQ: AEHR) announced on June 17, 2026, that it has received a follow-on production order for a fully automated FOX-XP wafer-level burn-in (WLBI) system from a major customer developing silicon photonics-based transceivers.

The system is configured to test nine wafers in parallel and includes a fully integrated WaferPak Auto Aligner plus a full set of FOX WaferPak Contactors. Delivery is scheduled within the next six months.

This is a follow-on order. Aehr first engaged the customer only seven months ago with the explicit goal of reaching volume production within six months. That timeline was met: Aehr delivered one full production system and two engineering systems by May 2026.

The customer is described as a global leader in networking products and solutions and a major supplier to the data center optical transceiver market. It is ramping advanced silicon photonics transceivers for data center networking and optical I/O to address accelerating demand for high-speed fiber optic links in hyperscale AI and cloud data centers. The customer has already provided Aehr with a forecast for additional systems in calendar 2026 as it expands capacity for next-generation hyperscale deployments.

Key technical and market context from the release:

• Silicon photonics transceivers are positioned as offering higher data rates, lower power consumption, longer reach, improved thermal performance, and reduced electromagnetic interference versus copper interconnects.
• Aehr states it is the market leader in WLBI for silicon photonics transceivers, with its FOX wafer-level systems now deployed to more than 25 customers.
• The FOX-XP platform supports high-parallelism, high-temperature, and high-power WLBI with precise temperature control to identify early-life failures before packaging and reduce cost of test.

CEO commentary (Gayn Erickson, President and CEO):

“We are excited to receive this follow-on order for a full production FOX WLBI test cell, which reflects the urgency of the production ramp now underway to support the massive buildout of hyperscale AI and cloud data centers… We first engaged with this customer only seven months ago with an objective to move quickly to volume production within six months. Aehr was able to demonstrate the production-ready capabilities of our fully integrated test cell to meet the customer’s performance and throughput requirements in a remarkably short period of time… We believe Aehr is well positioned to participate in what could be a significant multiyear expansion of silicon photonics production driven by the growth of fiber optic interconnects in hyperscale AI data centers. This customer engagement further validates wafer-level burn-in as an increasingly important part of silicon photonics manufacturing flow and highlights the potential for silicon photonics to become a meaningful long-term growth driver for Aehr’s WLBI business.”

Actions to take / what to monitor (directly tied to disclosed facts):

• Track order flow and revenue timing: One system is now under order with delivery inside six months (by ~December 2026). The customer forecast for additional systems in 2026 provides a visible pipeline signal—watch Aehr’s subsequent quarterly updates for incremental order announcements or backlog commentary from this relationship.

• Assess qualification-to-production velocity: The seven-month engagement-to-initial-delivery timeline (with follow-on already secured) demonstrates a repeatable path from qualification to volume. Other silicon photonics developers or test providers should benchmark this cycle time when planning their own ramps.

• Evaluate WLBI capacity needs: The emphasis on nine-wafer parallel testing plus full automation (WaferPak Auto Aligner + contactors) underscores the requirement for high-throughput, high-power burn-in to support cost-effective scaling. Photonics transceiver manufacturers and their supply-chain partners may need to audit or expand similar wafer-level capabilities ahead of broader hyperscale optical I/O deployments.

• Monitor silicon photonics as a growth vector for test equipment: Aehr explicitly frames this as potential “significant multiyear expansion” and a “meaningful long-term growth driver” for its WLBI business. Stakeholders should watch for follow-through orders from this customer and any new silicon photonics logos as AI data center fiber-optic interconnect demand accelerates.

• For investors/analysts: The combination of rapid initial ramp success, a live follow-on order, and an explicit 2026 multi-system forecast from a hyperscale-focused networking leader offers a concrete data point on execution in the emerging optical interconnect segment.
