SELECT Synchro
Transform Your Selective Soldering Process

The SELECT Synchro™ is a selective soldering systemdesigned for high-volume through-hole and mixed-technology
surface mount soldering applications and maximum
throughput. The system simultaneously processes up to sevenprinted circuit boards with its highly flexible configurationand compact footprint. Process boards up to 2500 mm longand up to 460 mm wide with the standard Synchro system
and up to 680 mm wide with the Synchro XL.
Versatility. The Synchro system easily flexes to support
various soldering applications, including single-sided, doublesided through-hole, or mixed technology surface mount andthrough-hole assemblies. The system configuration includes
a Microdrop drop-jet fluxer and can accommodate up to fivesolder nozzles to apply lead-free and leaded alloys. Various
options provide added flexibility.
Value. With a reputation for innovation, Nordson SELECT
process solutions deliver a maximum return on investment
and low cost of ownership. From initial process development
through full-scale production, you have the support ofour experienced worldwide engineering, applications
development, and technical service network.

Benefits•Boards continuously travel through thesystem, boosting throughput by 20-40% for
most applications, with more gain possible
if conveyance and soldering times arecomparable.

•Soldering work is automatically balanced
between soldering pots to increase
throughput further.

•Due to the minimal pot and fluxer motion in
the conveyor direction, the system footprint
is reduced by 60% compared to traditional
multi-station soldering machines.

•Process up to seven printed circuit boards
simultaneously using different alloys andnozzles or one fixed nozzle for all yourproducts.

•Supports five solder pots, each with theability to accommodate different nozzle sizes,eliminating the need to change nozzles.
