Faqs

1. What materials are Silicon Wafer Tweezers made of?

Silicon Wafer Tweezers are typically crafted from anti – magnetic and anti – acid stainless steel, such as SA stainless steel. This material offers high resistance to corrosion from acids and prevents magnetic interference, which is crucial when handling sensitive silicon wafers. Some tweezers may also be made from materials like PEEK (Polyether – ether – ketone), which is ESD – safe and heat – resistant up to a certain temperature. For example, PEEK tweezers can withstand temperatures up to 250 °C (short exposure at 300 °C), although they are not compatible with nitric and sulfuric acids.

2. How do I choose the right size of Silicon Wafer Tweezers for my wafers?

The size of the tweezers should be selected based on the diameter of the silicon wafers you are handling. Tweezers are available in various sizes to accommodate wafers ranging from 2” – 8” in diameter. For instance, if you commonly work with 3” wafers, you can choose long tweezers specifically designed for that size, which may feature a standard serrated handle for better grip. Make sure the tip style and size of the tweezers can securely hold the wafer without causing damage.

3. What are the different tip styles available in Silicon Wafer Tweezers and their uses?

There are several tip styles. General – purpose tips are suitable for basic wafer handling. Precision – engineered flat paddle tips are designed to safely hold and handle silicon wafers, providing a larger contact area for better stability. Some tweezers have multi – tooth blades that further reduce contact with delicate wafers, minimizing the risk of scratching. There are also tips with features like opening limit pins or wires to control the opening width and prevent over – opening, which could damage the wafer.

4. Can Silicon Wafer Tweezers be used in high - temperature environments?

Certain types of Silicon Wafer Tweezers can be used in high – temperature environments. PEEK – made tweezers can tolerate temperatures up to 250 °C during normal use and 300 °C for short exposures. Stainless – steel tweezers also maintain their structural integrity at relatively high temperatures, but their magnetic and chemical resistance properties may be affected at extremely high temperatures. Always check the product specifications for the maximum temperature limit of the tweezers you are using.

5. How do I ensure the Silicon Wafer Tweezers do not scratch the wafers?

Our Silicon Wafer Tweezers are designed with features to prevent scratching. They often have smooth – polished, non – glare surfaces to avoid any rough edges that could scratch the wafer. Some tweezers come with Teflon coating upon request, which further reduces the risk of scratching. Additionally, the design of the tips, such as the use of multi – tooth blades to minimize contact area or the presence of stopping pins and graduated lower paddles to prevent the wafer from slipping, helps in preventing scratches during handling.
