Estimated reading time: 1 minute

Federal Electronics, a leader in providing advanced electronic manufacturing services, has enhanced its surface mount technology (SMT) operations with the installation of a new Heller Industries reflow oven at its facility in Hermosillo. This upgrade supports the company’s continued growth in high-reliability markets such as aerospace, medical, industrial, and instrumentation.

The new Heller oven brings a range of performance advantages to Federal Electronics’ SMT line. With convection-based heating, the system ensures consistent and precise thermal profiles across a wide range of board types and solder paste formulations. Its high throughput capability allows for smooth, uninterrupted production, even when handling complex or densely populated assemblies.

In addition to uniform heating, the oven includes a highly efficient cooling zone, delivering tightly controlled ramp-down rates to protect component integrity. Integrated conveyor systems maintain stable board transfer, ensuring accuracy throughout the reflow process. These features are essential for maintaining solder joint integrity and repeatable results across high-mix production runs.

A key benefit of the new installation is improved process control. The system enables fine-tuning of temperature zones and conveyor speeds to accommodate a wide range of PCB assemblies. For Federal Electronics, this flexibility is especially important when supporting both low- and medium-volume programs across its U.S. and Mexico operations.

“Adding this level of thermal precision and repeatability further strengthens our manufacturing consistency across borders,” said Ed Evangelista, President, Federal Electronics. “It’s part of our commitment to ensuring customers receive the same level of quality and control whether their product is built in Rhode Island or Hermosillo.”

The Heller system supports Federal Electronics’ broader U.S.-Mexico sourcing strategy, allowing OEMs to benefit from cost-effective manufacturing in Mexico without compromising on technical standards or product reliability.
