Electronics Standard Products: Soldering

• The GoWave is a powerful soldering system for those just entering into mass-soldering operations. This system is suited to a variety of applications ranging from entry-level mass-soldering to soldering in small or medium-sized batches. It also provides an economical soldering solution for universities, schools and laboratories.
• The GoWave is especially featured with its innovative nozzle concept which is ideally suited for nearly all soldering tasks.
• A special feature of this machine is its compact, but performance oriented design. Offering a fluxer module, an efficient preheater, innovative soldering area and microprocessor control, the GoWave presents the finest soldering technology in its class.
• The redesigned GoWave features a longer reflection tunnel to promote better energy transfer to the board.
• A new spray fluxer with HVLP technology controls quantity and spray pattern of the flux and helps to reduce flux consumption.
• A new control unit with touch screen and USB interface completes the new concept.

• With the wave soldering system PowerWave, SEHO consequently realized a machine concept which offers a remarkable performance at simultaneously low investment costs. Complex SMD boards are as reliably soldered as conventional assemblies - due to up-to-date solder nozzle geometries and a flexible preheat area.
• The modular construction of SEHO PowerWave offers the ideal concept for all production requirements and allows the machine to be integrated into existing fully automated production lines.
• Performance reserves for the user have been created with the high performance pre-heating. SEHO PowerWave is available with either 1200 mm preheat length or 1800 mm. Depending on your production requirements, SEHO PowerWave may be equipped with a chain/finger conveyor system or with a solder frame conveyor for the processing of pallets.
• The heart of the machine, the soldering area, is designed with a degree of flexibility that may perform all realistic soldering operations. Modern and innovative solder nozzle geometries provide ideal soldering results.

• SEHO MaxiWave 2300 C is an up-to-date full tunnel nitrogen wave soldering system which is featured with low investment and operation costs. Simultaneously the machine ensures perfect soldering results due to its innovative soldering area.
• The unique design of SEHO’s full-tunnel systems provides a stable, low-oxygen soldering atmosphere without complicated mechanical parts. Through gas jets located in the soldering area, nitrogen enters and flows through the tunnel. This flow displaces the oxygen from the process chamber. The advantage of SEHO’s technology is confirmed by minimal nitrogen consumption and a low residual oxygen concentration which is achieved within shortest time.
• The MaxiWave 2300 C is featured with an integrated spray fluxing unit which is provided with an exhaust to avoid spray vapours within the process area.
• The preheating area consists of 6 heating zones with a total length of 1800 mm. As the standard, the MaxiWave 2300 C is equipped with IR preheaters, however, quartz emitters or convection modules also may be integrated to meet special production requirements. Modern and innovative solder nozzle geometries in the flexible soldering area provide ideal soldering results.
• Depending on production requirements the MaxiWave 2300 C either may be equipped with a flexible chain and finger conveyor or with a transport system for processing of solder frames.

• The MWS 2300: perfect in every detail. Based on SEHO's worldwide leading nitrogen technology, the precision machine tooling and the modular design of the system, makes the nitrogen wave soldering system MWS 2300 a powerful piece of equipment. It is ideally suited to solder demanding printed circuit boards – even at high throughputs.

• The flexible preheating zone configuration with a preheat length between 1800 mm (70.8 inch) and 3300 mm (129.9 inch) makes it possible to suit your specific production requirements. Should your requirements change in the years to come, simply – and without great expense – change the configuration of the soldering machine.

• The fluxing unit may be integrated in the machine or used as an external module – according to requirement.

• Several factors ensure a clean process area and consequently the lowest possible maintenance costs: As a standard the MWS 2300 is equipped with filters at the inlet and unloading end, collecting the condensates. Beyond this, the machine may be optionally equipped with a controlled and integrated exhaust 4-stage filtering system.

• Special highlight is the integrated temperature-controlled convection cooling module. It cools the assemblies already below liquidus before they are leaving the machine. This is of advantage – particularly at high temperature applications as for example in leadfree soldering processes.
• Additionally, MWS 2300 features an intelligent solder channel suspension. It compensates for any changes due to thermal conditions, because the process relevant distance between solder wave and assembly remains always the same. Thus, it ensures perfect soldering results.
