In the realm of printed circuit boards (PCBs), reliability under harsh conditions is paramount. Standard PCBs can falter when exposed to extreme temperatures, jeopardizing performance and longevity. This is where High Tg PCBs from Cirexx International come into play, offering robust solutions designed to withstand the rigors of challenging environments.

Understanding High Tg PCBs

High Tg, or glass transition temperature, signifies the point at which the PCB material transitions from a glassy state to a rubbery state. For High Tg PCBs, this transition occurs at temperatures exceeding 170°C, with typical ranges between 180°C to 225°C. This elevated Tg ensures that the PCB retains its structural integrity and electrical properties even when exposed to high heat.

Applications and Benefits

High Tg PCBs find extensive application in industries requiring resilience and durability. These include automotive (for parts subject to vibration and heat), aerospace (for components within aircraft and satellites), and industrial equipment (where reliability under tough conditions is crucial).

Key Features of High Tg PCBs

Cirexx International specializes in fabricating and assembling High Tg PCBs using a variety of advanced materials and processes:

• Design & Testing: Ensuring precision with features like 2 mil trace widths, 3 mil air gaps, and rigorous testing standards (IPC class 2/IPC class 3).
• Drill & Rout: Offering flexibility in hole types (blind vias, buried vias), and precise routing for complex board geometries.
• Lamination: Employing vacuum and sequential lamination techniques for multi-layer boards up to 30 layers.
• Plating: Providing various plating options including conductive and non-conductive via fills, immersion gold, and ENTEK for RoHS compliance.
• Materials: Utilizing a range of materials such as flex and rigid-flex substrates, RF and high-speed materials, and heavy copper for power distribution.
