Component Specifications

Definition
The Motherboard Fixture Tray is a specialized component within Thermal Chamber Assembly systems, engineered to provide stable, repeatable positioning of printed circuit boards (PCBs) during environmental stress testing. It ensures consistent thermal contact, prevents vibration-induced damage, and maintains electrical isolation while accommodating various motherboard form factors through adjustable mounting points.
Working Principle
Utilizes mechanical clamping and thermal interface materials to secure motherboards while allowing uniform heat transfer during thermal cycling tests. The tray maintains dimensional stability across temperature extremes (-40°C to +150°C) and provides electrical insulation to prevent short circuits during testing procedures.
Materials
6061-T6 aluminum alloy (primary structure), PEEK (polyether ether ketone) insulating components, stainless steel fasteners (A2-70 grade), silicone thermal pads (3-5 W/m·K conductivity)
Technical Parameters
  • Weight 2.3 kg
  • Surface Flatness 0.05 mm/m²

Frequently Asked Questions

What types of thermal tests is this fixture tray designed for?

This tray is optimized for thermal cycling tests, thermal shock tests, and high/low temperature storage tests according to industry standards like JEDEC and MIL-STD-883.

How does the tray prevent damage to sensitive motherboard components?

It uses PEEK insulating posts and silicone pads to create non-conductive mounting points, while precision machining ensures even pressure distribution without component stress.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
