SMT fixtures (often referred to in the industry as SMT Pallets, Carriers, or Jigs) must withstand high temperatures, repeated thermal cycles, and provide electrostatic discharge (ESD) protection.

Here are the most common materials used, detailed in English:

1. Synthetic Stone (Durostone / Ricocel)

• Description: This is the industry standard and most widely used material for SMT reflow and wave soldering pallets. It is a heavy-duty, glass-fiber reinforced plastic.

• Key Features: Excellent thermal stability (can withstand over 300°C), highly durable for thousands of reflow cycles, maintains strict dimensional stability, and provides excellent ESD (Electrostatic Discharge) protection.

2. Aluminum Alloy (Aluminum 6061 / 7075)

• Description: Frequently used for high-precision CNC machined fixtures, just like your LCD soldering jig.

• Key Features: Extremely rigid, allows for very tight machining tolerances (like 0.01mm), and has a long lifespan. Often black-anodized to prevent glare and add a protective layer. Note: Because aluminum acts as a heat sink, engineers must design the fixture carefully so it does not absorb too much heat and disrupt the reflow oven's temperature profile.

3. FR-4 (Glass-Reinforced Epoxy / Fiberglass)

• Description: The same material used to make standard PCBs.

• Key Features: A highly cost-effective alternative for simpler SMT carriers or short-run production. It offers excellent electrical insulation but degrades much faster than Durostone when repeatedly exposed to the extreme heat of a reflow oven.

4. Bakelite (Phenolic Resin)

• Description: A traditional, dense synthetic plastic.

• Key Features: Extremely cheap and easy to machine. However, it is rarely used for high-temperature SMT reflow ovens. It is primarily used for Testing Fixtures (like ICT/FCT testing jigs) or manual assembly fixtures where high heat is not a factor.

5. Magnesium Alloy

• Description: Sometimes used as a lightweight alternative to aluminum.

• Key Features: Lighter than aluminum while maintaining excellent dimensional stability and heat dissipation, making it suitable for large SMT carriers that need to be handled manually.

Summary for B2B Context: If your customers ask about materials, Durostone is the premium choice for standard PCB assembly reflow, while Aluminum Alloy is the top choice for high-precision manual soldering or specific alignment jigs.
