Selective soldering within 2 seconds Selective soldering processes ensure economic success, if they are precisely adapted to applications. A key factor in this context is productivity, namely, the throughput of assembly units achieved through soldering systems. In many fields of manufacturing, modern selective soldering systems are increasingly replacing conventional wave soldering systems. However, in high-volume manufacturing, in order to achieve the same throughput in selective soldering as in wave soldering systems, simultaneous selective soldering processes are required. These processes...

Fluxing with highest precision Superior process safety and best positioning accuracy also at highest throughputs Flux module with four multi-drop heads; superior process safety through flux volume metering The flux system of a multi wave soldering machine must live up to many high requirements simultaneously. High quality flux processes require not only precision but also speed and a high level of reliability. The sections of the PCB that are not wetted by the selective soldering waves may also not be supplied with flux material. In order to ensure this, today, modern micro-drop flux heads are...

Perfect preheating Reproducible and economic – the ideal combination of bottom and top-side heating Perfect preheating concept incorporating a dynamic bottom-side and top-side heating Thanks to multi wave soldering processes, extremely short cycle times can be achieved. However, this requires a steady improvement in temperature performance, particularly in lead-free soldering processes. Correct activation of flux materials for optimal wetting of the solder joints is essential to ensure good capillarity and, consequently, rising of the solder. If assembly units feature a high heat capacity, when...

Close-up of a The core of a multi wave solder solder nozzle pLcite pot consists of a product-specific with demanding nozzle geometries solderin0 tool: the nozzle plate. This consists of a huge base-plate, on which the solder nozzles are arranged so that their size and position correlate with the solder joints on the board assembly. taken into account for an optimal process window. The longstanding experience in the structural design of solder nozzles and the correct choice of materials and of a suitable protective layer against the attack of lead-free solders, guarantee stable soldering results,...

“Safety First” – Individual solder nozzle design and process approval Design steps for the development of a solder nozzle Solder nozzle plates and productspecific component hold-downs are designed individually for each customer with a 3D-CAD system. No matter, if standard nozzle designs or customized nozzle layouts are required, the body of the solder nozzle is milled from a whole piece. After all nozzles have been manufactured, they are mounted on the solid base plate. Additional support pins are placed to prevent the PCB from bending during the soldering process. the geometry of the electronic...

Today it has become state of the art to substitute classic wave soldering by selective soldering systems. This corresponds with the demand to manufacture large board assemblies in the same cycle time as in standard wave soldering processes. The VERSAFLOW Multiwave XL fulfils these demands and is the first system which can manufacture large board assemblies in high volume production. The modules of the Multiwave XL are based on approved Ersa technologies and meet the highest quality demands that are posed on production facilities and final products by electronic manufacturers all around the globe....

The preheating modules are equipped with fast reacting quartz emitters, which quickly and uniformly heat up the board assemblies to the required temperature. The first three preheating modules are arranged before the first soldering module. One more preheating module is placed between the first and the second soldering module. Each module can be separately adjusted in stages, which allows product-specific temperature profiles and increases the reproducibility. Each preheating module can also be equipped with an optional upperside convection heater. Multiwave soldering units operate in a stable...

Maximum machine availability Ersa ECOCELL with 2 preheating modules and 2 „on the fly“ multi wave pots in combination with Ersa FIFO TOWER C The latest generation of Ersa multi wave solder pots is maintenancefree, since its electromagnetic solder pumps have no moving parts. The performance of the pump can be adjusted stepless and the aggregate is suitable for all common lead-free solders. „On the fly“ setup option with two soldering modules The solder nozzle plate an den component holder system are equipped with quick fasteners in order to reduce the downtime during a tool change to a minimum....

All Ersa selective soldering systems are operated with ERSASOFT, the dedicated PC-software. This machine visualization software offers numerous functions, which allow for an error-free operation of the system by the operator. During the design of the user interface, great care was taken to make data entry a comfortable task. To achieve this, the icons of the touch screen were given adequate size. Identified by colour and uniformly structured, the dialogues provided offer quick orientation. Through clear distinction of the entry masks from the dialogues for the basic equipment configuration, it...
