The machine measures only 1.70 meters in length, which makes suitable for many production sites. With the option to run the conveyor either left-right or right-left, our Cerno fits into any production environment and every corner.
A processing area of 508 x 508 mm offers you numerous possibilities. Throughput can be significantly increased with the various processing modes.
The possibilities with our Cerno are diverse. Whether as a batch machine or integrated into a highly automated soldering line, the Cerno can handle it all and provides you with the opportunity to grow alongside it.
For inline or inline/batch operations with small to medium quantities, our Cerno is the perfect, flexible solution. Fluxing, preheating, and soldering all occur in a single zone within the system. With its large processing area, circuit boards up to 508 x 508 mm can be accommodated. Various production modes (single, double, parallel) can be selected, adding to the flexibility. The option for left-right or right-left transport provides additional flexibility, allowing for wall placement of the system and plenty of room for automated line concepts.
Thanks to the high flexibility of the system, users can scale with their Cerno. The machine can be installed in a corner to save space and operated in left-right or right-left mode, with the circuit board entering and exiting from the left. Loading of the system can be done via a conveyor belt, buffer, or magazine handler. As expansion continues, the system can be integrated into a full line setup, whether with solder frames with lifts and return transport, magazines, or a highly flexible combination of both. The Cerno knows no limits in this segment.
Numerous variables affect the selective soldering process. Monitoring and controlling quality-relevant parameters are thus crucial for reproducible soldering quality. Besides flux and solder levels, factors like wave heights, circuit board warpage, flux application, and preheat temperature are primarily decisive for soldering results. For some applications, alignment mark detection is indispensable.
Regulated top and bottom heating ensure a wider process window and are particularly important for through-hole soldering. Additionally, a camera provides the capability to monitor the process continuously. Following extensive testing with electromagnetic pumps, the use of titanium pumps with precision impellers has proven to be more process-secure and maintenance-friendly. Moreover, this solution remains open to the increasing interest in low-melt solutions (low-melting alloys).
Producing the required quantity within the optimal time with the best total cost of ownership is the company’s objective. Alongside reproducible quality and throughput, both direct and indirect costs must be considered. If flux application can be adjusted to the conditions and solder consumption is more or less predetermined by the layout, the necessary nitrogen consumption (nozzle wetting) and associated costs strongly depend on the required nitrogen purity level. Our systems require only purity grade 4.0 (purity 99.99). Additionally, in considering total cost of ownership, maintenance effort should never be overlooked. Just as with the tool-less maintenance of the titanium pumps with precision impellers, operator and maintenance friendliness were always key considerations in the development and design of our systems.
Is the Cerno a batch or inline system?Both! This is the great advantage of the highly flexible system. Pure batch systems are usually very labor-intensive. PCBs always have to be placed and removed by hand. The Cerno offers the option of extending the soldered PCB back in the transport direction in which it was inserted. This makes it possible to install a conveyor belt, a buffer or a loader module in front of the system. With smart.e.connect and smartControl (hard software from smartTec), you have all the functions of a modern line - even with just a conveyor belt. This usually has a very positive effect on the ROI. |
What is the difference between the Intergra 508.3 and the Cerno?The Cerno system is designed for smaller quantities and longer cycle times. Fluxing, preheating and soldering are carried out in one station. The Integra 508.3, on the other hand, has its own fluxing zone, a preheating area and then soldering. |
What automation options do you have with your systems?All of them! Depending on the product and quantity, we can design the ideal soldering line for your selective soldering tasks. The degree of automation should always be based on an ROI analysis. This means that the investment in a production line and the degree of automation should be amortized within a reasonable period of time. |
Does your system require nitrogen and what purity is needed?Yes, nitrogen is required for the selective soldering process. What sets us apart from our competitors - with all our selective soldering systems - is that we only need to achieve a purity of 99.99, which corresponds to purity grade 4.0. The savings compared to 99.999 (class 5) are striking. A separate nitrogen generator for the systems is therefore often the more cost-effective solution. |
Do you also sell the right nitrogen generators for your systems?Yes, we specify the optimum solution for you - as much as necessary, as little as possible. |
Could the Cerno also be installed in a corner to save space?Yes, if the required throughput allows, you can set up a fully-fledged production line in the corner with the Cerno. Thanks to the option of running the system L-R-L, you can implement a space-saving, automated concept that is precisely tailored to your requirements. |
