One of the crucial factors for Assembléon’s pick and place machines is that they rely on the speed by which electronic components can be placed on a Printed Circuit Board (PCB). LIME supports Assembléon by developing new innovative algorithms that determine not only the proper order in which the pick and place actions are carried out but also the order in which the selected components are supplied. As a result of the optimization, the product throughput is increase and at the same time the flexibility of the employed methods also leads to a reduction of the complexity in the underlying optimization process.
"Assembléon builds the most flexible and efficient assembly machines for electric components. The huge number of possibilities to place these components create a challenge to find the planning with the shortest cycle times. LIME constructed an improved optimizer, which we implemented together and integrated in our newest iFlex machines."
CUBICselect® (LIME's powerful packaging optimization software) is already used successfully for Abbott Vascular, a global leader in cardiac and vascular care with market-leading products. With CUBICselect® LIME helped Abbott Vascular to reduce the shipped volume by more than 30%. Abbott Vascular honoured LIME with a Vendor Excellence Award, for a job well done.
Jeroen van der Niet, Manager Business Excellence, Abbott Vascular, Heerlen:
"Not in the least part because of the extensive data validation that was carried out beforehand by LIME, the introduction of CUBICselect went on without problems and we saw an immediate improvement of the filling rate. An additional advantage is that the introduction of CUBICselect led to a standardisation of our pacakaging process."
In order to reach temperatures of -196 degrees Celsius (where Nitrogen condenses and becomes a fluid), the Sterling cooler is an efficient device. The cooling principle is based on two independent pistons that successively compress helium in a cyclic manner at a frequency of 25 times per second. With standard software simulation a series of such compression cycli takes too much time. LIME has optimized the model appropriately (and in particular by taking special care of the “wall effects”) and thus reduced the computational time to reasonable proportions. A further benefit of the work that has been carried out is that when there is a requirement to “up scale” to larger coolers the implementation of the model is such that it avoids having to construct expensive intermediate forms.
