Nordson Electronics Solutions has introduced the new SELECT Synchro™ selective soldering system for high-volume printed circuit board assembly applications. Especially, the SELECT Synchro works as a multi-station selective soldering system (patent pending) that uses a unique, synchronous motion to increase throughput. In addition, it helps improve cost-of-ownership and provide flexibility for electronics manufacturers.

The innovative SELECT Synchro system can replace existing selective soldering operations to improve yield. Furthermore, it saves space for many through-hole and SMT mixed-technology soldering applications.

Moreover, the Synchro system can help electronics manufacturers to step away from wave soldering with its faster, flexible, and efficient operations, compared to typical selective soldering solutions.

Key Benefits of SELECT Synchro

The SELECT Synchro of Nordson Electronics has many benefits. First, it offers increased throughput. Particularly, it eliminates board conveyance time by as much as 25 percent while delivering outstanding solder joint reliability, boosting throughput 20 to 40 percent for most applications.

Second, it offers improved cost-of-ownership. For that reason, the space-efficient system is as much as 4X shorter than typical selective soldering equipment. Hence, resulting in 60 percent reduction in footprint.

The system also automatically balances the process to broaden flux and soldering flexibility, increasing throughput while providing traceability. Next, it offers flexibility. Configured with five solder pots to match manufacturing needs for different alloys, and different or singular nozzles. The system handles long boards up to 460mm wide and 2500mm long in the standard model and boards up to 680 x 2500mm in the Synchro XL model.

Lastly, the SELECT Syncrho offers enhanced quality. Thus, improved process controls are available for closed-loop wave height check and automatic adjustment, fluxing process controls, process camera for viewing nozzles, and board warpage control.

How it Works

Inside the innovative SELECT Synchro system comes with a board pulled at a constant speed through fluxing, pre-heating, and soldering process. The program of flux and solder applicators can follow and treat boards as they travel through the equipment to deliver synchronous-motion selective soldering. Multiple solder pots and different nozzle sizes are available to provide flexibility with solder quantities, solder alloys, and board designs.

“By moving the target board as well as the flux and soldering applicators, the operations speed up, and the system reduces in size,” explained Florian Strohmayer, product line manager, Nordson Electronics Solutions.

In addition, Strohmayer said, “In terms of throughput, the SELECT Synchro concept can replace wave soldering equipment while increasing the soldering quality and reducing the cost of ownership.”

The unique design inside the SELECT Synchro system increases throughput by reducing the time spent conveying boards as much as 25 percent. Furthermore, multiple solder pots can be configured. At the same time, the system balances the whole process for efficiency and flexibility to deliver superior solder joint reliability. In addition, the machine’s size can be as much as four times shorter than a typical selective soldering system. For example, shrinking in length from 10 to 2.5 meters.
