Ejector pins are commonly used for the die pick up process ejection. We supply a variety of material to accommodate the sensitivity of the different applications. We have Tungsten Carbide/ High Speed Steel/ Red Ultem Plastic/ Translucent Ultem Plastic in the range of hardest to softest based material. The selection will depend much on the dies dimensions, material, and "default setting'' of the needle holder parameter.
Our rubber tips designs include bump dies to LED packages. Our standard rubber tips uses NBR (Nitrile Butadine Rubber) & for high temperature requirements Viton is recommended. The maximum working temperature can reach up to 250°C. Rubber collets are great for sensitive surface dies which requires soft cushioning during pickup. Our material hardness from 50HRC to 80HRc. Customization for complex application can be supported without compromising on warpage or related problems.
Carbide pick up tool is excellent for sorting processes. The 85-82HRC material has an impressive wear rate for longer lifespan. The max working temperature for this tool is up to 2000 °C and can be mirror surface finished. This gives the tool a glossy and extremely flat surface for maximum contact area.
The Vespel collet is a popular choice for high temperature application. We supply two variation of vespel (SP-1 & SP-21). Standard vespel max working temperature is 288°C – 482°C (Intermittent). This is suitable for applications which are subjected to high heat and has a sensitive pick up surface. The Vespel plastic characteristic compliments Dies & LED packages.
Stamping tools are commonly used for large dies epoxy pattern. This can range from 1x1mm to 50x50mm dies. We supply all types of nozzle patterns to accommodate today's complex die designs. Customization is common for complex designs. Generally, the design and selection of nozzle will depend on epoxy viscosity and dispensing pattern.
Dispensing tools are commonly used for large dies epoxy pattern. This can range from 1x1mm to 50x50mm dies. We supply all types of nozzle patterns to accommodate today's complex die designs. We’ve fabricated some very complex design for special applications. Generally, the design and selection of nozzle will depend much on epoxy viscosity and dispensing pattern.
Pepperpots and needle holders are typically used for setting the pattern of ejection. This depends much on the suitability of the dies and parameter setting which is typically decided by the process engineer.
