The SPA-NC Series of Ebso Maschinen- und Apparatebau is highly flexible, automatic selective soldering cell with manual load/unload. There are a number of PCBs that are assembled with thermal sensitive components and complex SMD layouts, which are challenging and likely unsuitable for processing in a traditional wave solder machine. To overcome the soldering challenges, some electronics manufacturers will use custom solder masks to cover the SMD components. The platform overcomes the soldering challenges by automatically transporting the PCB to each critical soldering step via an XYZ-axis carrier – microdrop fluxer, bottom-side preheater and soldering modules. The final result: Perfect solder joints and a reliable and repeatable process. To reduce surface tension of the solder wave, and to achieve the highest quality soldering results, nitrogen is provided to the solder bath and solder pump unit. The fast remove pump system designed by the company, enables maintenance personnel to access the pump within minutes. Furthermore, the solder bath and pump in the system are made of Titanium, making the machine suitable for both lead and lead free production environments. Utilizing a “Point & Click” feature, soldering programs are easily created within minutes. Programming is intuitive and easy. A scanned image of a bare PCB is all that is needed. Once the PCB is scanned, it is loaded into the editor, and appropriately scaled. The software automatically calculates the correct X and Y value. Because the operator is looking at the PCB image when creating the program, he can see all neighboring components to optimize the program and select the appropriate nozzle. This negates the requirement for expensive teach cameras.
