R4 Rubber Tips
the industry standard for performance and reliability
The R4 rubber tip is designed for pick-up of BGA or other substrates with solder balls. The rubber tip can fit either around the balls or between rows/columns of balls. Custom tip dimensions are available (requires mold tooling).
Material Specifications
Hardness : 79 Shore A
Heat resistance : 130 deg. C
Static dissipation : 0.01 to 0.03 sec.
Ionic purity : less than 10 ppm
Static dissipation measured as time to dissipate a charge from +/-5000 V. Ionic purity measured by boiling rubber in DI water and analyzing the water extract for fluoride, bromide, chloride, potassium, nitrate, phosphate, sulphate, sodium and silicon.
