PELCO replaceable tip wafer tweezers, style 259

ESD-safe wafer tweezers are style 259 (fine tips). Soft tips specially designed for the electronics industry to help with easy to mar samples and brittle materials such as Si pieces. These ESD-safe tweezers are made of non-magnetic, acid resistant stainless steel with replaceable carbon fibre reinforced tips. Made in Switzerland. Replacement tip kit includes 1 pair of tips and screws.

PVDF (polyvinylidene fluoride) reinforced with carbon fibre:

• Excellent mechanical strength and toughness
• Smooth surface
• Heat stabilised, high heat capability, continuous use temperature up to 150?C
• High purity (clean room and medical devices approved, low extraction value)
• Excellent chemical resistance to most aggressive substances and solvents. Resistant to halogens. Not compatible with NMP.
• Outstanding resistance to hydrofluoric acid (40% conc., 90?C, nitric acid (50% conc., 90?C), hydrochloric acid (36% conc., 90?C)
• High abrasion resistance
• Resistant to UV and nuclear radiation (sterilisation)
• ESD safe material
• Typical applications include handling of very scratch and contamination-sensitive components, cleaning and etching processes

Carbofib (Polyamide 66) reinforced with carbon fibre:

• Heat stabilised
• Very high rigidity, excellent tensile and flexural strength, fatigue and creep resistance
• Low friction, self-lubricating properties, excellent wear and abrasion resistance
• Good heat capability
• Good chemical resistance (oils, grease, fuels, non-polar solvents); not resistant to strong acids, alkalis and hot water or steam
• ESD safe material
• Very low coefficient of linear thermal expansion
• Typical applications include handling of sensitive components and devices (electronic components, micro-mechanical parts, glass and ceramic substrates, capillary, etc.)

PEEK (polyether ether ketone) reinforced with carbon fibre

• Very hard, rigid, high tensile and flexural strength, very high wear resistance
• High heat capability (260-300?C), good dimension stability, low thermal linear expansion coefficient
• Excellent resistance to chemicals and aggressive agents, excellent resistance to thermal ageing. Compatible with NMP.
• ESD-safe material
• Typical applications include handling of components in cleaning/chemical/assembly processes also at high temperature (soldering)
