Yaskawa: Sigma-X servo systems for the electronics industry
Smart features for high-precision production and handling applications
Yaskawa's new Sigma-X high-end servo system extends the technical possibilities in semi-conductor production: specialist machine and system manufacturers and users in the electronics industry will all benefit from even smarter features.
To comply with sector-specific regulations, such as SEMI S2 and SEMI S8, the machines and systems used to manufacture semi-conductors must fulfill the most stringent precision standards. The performance requirements for the servo motors used in this industry are therefore correspondingly exacting. This is especially true for pick & place applications, such as those involved in circuit board assembly, wafer-handling and other technically complex automated tasks, such as wet etching. Reliability and availability are the decisive factors here, because down-times can cost a great deal of time and money. For this reason, servicing and maintenance tasks should be straightforward and possible to perform in a timely manner. Another critical factor is a long service life, to ensure a good return on initial investment costs.
Mastering complex applications
Servo systems have to handle a number of challenging tasks at the same time, for example, during crimping, when two components are joined together by a process of plastic deformation: they must maintain a constant, exact pressure at all times, and distribute this pressure across a number of synchronized axes. A further requirement is that movement can be stopped at any position, while ensuring that the stability of the process as a whole remains the same throughout the entire production cycle.
In coating processes, as a second example, plates that are rotating at high speed are sprayed evenly with liquid. To achieve a precise result, the ripples in the speed must be adjusted and reduced in a specifically targeted way. Tailor-made solutions can also be developed for other specific applications and to meet other exacting challenges.
