Connect the Dots: Five Best Practices for Designing Flex and Rigid-flex PCBsNew LPKF CuttingMaster 2122 Improves Depaneling Efficiency

LPKF has enhanced the performance of the proven and popular LPKF CuttingMaster depaneling system even more with a newly developed laser source. Initial applications demonstrate a significantly higher cutting speed and, as a result, an up to 25% higher output. For users, this yields a whole new dimension for improving efficiency in this price-to-performance range. It gives PCB manufacturers the full advantages of laser technology for the price of a milling machine.
Drawing on extensive expertise in both laser technology and depaneling, LPKF’s engineers have developed a special laser source that is now used in the latest addition to the CuttingMaster platform. It delivers precision and speed with high reliability. The time needed by the predecessor machine to cut a comparison sample in a 0.8 mm FR4 board with “FastCut” was already impressive at 7.3 seconds, but the new LPKF CuttingMaster 2122 does the job in just 5.9 seconds. That's a difference of nearly 20%, and it can even be more than that by using CleanCut technology. All this is achieved with the same invest. In the cutting of coverlayers, too, the new laser system achieves a considerable improvement for the price-to-performance ratio. Compared with the prior state of the art, the LPKF CuttingMaster 2122 makes it possible for users to achieve a whole new level of performance and added value. With it, LPKF combines the advantages of laser technology in a particularly cost-efficient system.
All laser machines of the LPKF CuttingMaster 2000 series are ideally suited to cutting of flexible, flex-rigid, and rigid PCBs – made of, for example, FR4, polyimide, or ceramics. With laser cutting, no mechanical or appreciable thermal stresses are introduced. Therefore, even sensitive substrates can be processed with high precision. Ablation products are directly extracted. The cutting channels are just a few µm wide for optimal panel area utilization.
Processing by the LPKF CuttingMaster is completely software-controlled. The layout files can be transferred to the machine with a click of the mouse – no lengthy changeover or prior elaborate tool manufacturing is required. Processing parameters and laser paths are adapted to take into account varying materials or cutting contours directly. The high level of automation of the compact system, which can be selected modularly depending on the application, results in high throughput and high repeatability.
