We make connections
It is only at the bonding stage that the right connections are made and the electrical contacts between the chip and its environment are created. This happens at lightning speed and with spot-on accuracy. Even the smallest error in positioning renders the whole chip unusable. This depends on using the right components in the drive of the X-Y table.
For example, these include ground INA planetary roller screws of series RGT... In conjunction with the miniature cage guidance unit RMWE, they are highly suitable for the high frequency, alternating short stroke operation in die or wire bonders. The small thread pitch of the spindle gives high positional accuracy. And if even that is not sufficient for you, we can supply you with a design already preloaded. For the very highest positional accuracy.
Let's go a step further, however. You can add INA screw drive components to your screw drive system to create a complete subassembly. For example, take our axial angular contact ball bearing unit ZKLR.. as a locating bearing, a locknut and a needle roller bearing as a non-locating bearing. Or even a different combination... whatever you decide – all the components are perfectly matched to each other and available from a single source.
If you are thinking about a high precision, economical guidance system for your X-Y table, you should also include our four-row miniature linear ball bearing and guideway assembly in your final shortlist. This INA solution is hard to beat for precision and cost-effectiveness.
