Diamond Pickup Tool for Liquid Crystal Devices
Liquid crystal devices are used in vehicles, smartphones and other devices indispensable to our daily lives. For vehicles in particular, not only are they used for electronic control as part of automatic driving technology, many crystal devices are also used for sensors and cameras for car navigation and safety functions. The further evolution of vehicles requires high-quality and low-cost liquid crystal devices to be manufactured. Tecdia contributes to the cost reduction of these liquid crystal devices through our “Diamond Pickup Tool for Liquid Crystal Devices”.
Long life pickup tools are required to reduce the cost of liquid crystal devices
Pickup tools for manufacturing liquid crystal devices are typically made of ceramics, which are insulators, as the elements may be destroyed if subjected to a build-up of static electricity. The tip of these liquid crystal device pickup tools are quickly worn as they pick up devices at a rate of one piece per second, requiring the tool to be replaced approximately every 2 weeks.
However, with the evolution of vehicles price competition for liquid crystal devices for vehicles began, creating a need for reduced manufacturing costs. For this reason a need for pickup tools with a longer life than conventional types arose in order to shorten tact time.
Successful development of a diamond pickup tool to replace ceramic types
As the need for pickup tools using materials with greater wear-resistance than ceramics for a longer service life, coupled with the ability to remain isolated from static electricity gained momentum, Tecdia presented a proposal for a diamond pickup tool. Tecdia’s expertise in diamond polishing enabled the diamonds a the heart of the tool to be polished, which is considered to be quite a difficult process, into a shape identical to that of conventional tweezers.
Moreover, the development of inexpensive diamond tweezers was a success also thanks to Tecdia’s proprietary diamond-to-metal bonding technology, enabling the only part of the tool that touches the liquid crystal device to be made of diamond.
After the proposal, samples were provided with short lead times and an evaluation started immediately. The evaluation concluded 3 times longer service life than ceramic was realized, spurring major liquid crystal device manufacturers on to make use of the product.
