Selective Soldering System
for Batch or In-Line Production

Features and Benefits

  • Batch or in-line platform with combined fluxing, preheating and soldering for highest possible process flexibility
  • Choice of single or dual drop-jet fluxers and solder pots for either simultaneous parallel or independent double processing modes
  • Parallel processing significantly increases machine throughput while double processing broadens soldering flexibility
  • Full titanium solder pots compatible with all solder alloys plus easy tool-free maintenance
  • Software control between different solder alloys without changing solder pots

The Cerna™ 508.1 is a robust selective soldering system delivering the optimum balance between flexibility, throughput and large board size. The Cerno™ 508.1 has many unique features, including combined fluxing, preheating and soldering for easy integration into batch or in-line production.


With its flexible configuration, the Cerno™ 508.1 is a versatile selective soldering platform and can be equipped for either single, parallel or double processing. Use of a single dropjet fluxer and solder pot allows soldering of printed circuit boards as large as 508 x 508 mm (20.0 x 20.0 in.).

Cerno™ 508.1S flux, preheat and solder configuration

When configured with dual drop-jet fluxers and dual solder pots, the Cerno™ 508.1 can be used in two different modes and is capable of processing up to 4 boards at one time. The parallel processing mode enables fluxing and soldering of two printed circuit boards at the same time doubling machine productivity.

Cerno™ 508.1PD flux, preheat and solder configuration

The double processing mode allows soldering with multiple size nozzles within the same program enhancing flexibility and increasing productivity. A single drop-jet fluxer and dual solder pots can be used in the double processing mode and is ideally suited for the use of two different solder alloys without requiring physical changing of solder pots.
