Solvent cleaning system eliminates
rejects

Gai-Tronics has had a potentially damaging quality problem solved by the installation of a cosolvent cleaning system from Kerry Ultrasonics.

Gai-Tronics has had a potentially damaging quality problem solved by the installation of a cosolvent cleaning system from Kerry Ultrasonics Based in Burton-upon-Trent, Gai-Tronics manufactures ruggedised telephones for use in arduous or hazardous environments around the world

Flux residues on the telephone circuit boards prior to conformal coating left them prey to corrosion.

Given the particularly harsh weather conditions in which these devices must operate, this deterioration could have caused the telephones to fail.

After installing a cosolvent machine from Kerry, Gai-Tronics was able to remove all traces of flux from its boards and has now completely eliminated rejects.

The Microsolve M350/2C cleaning system uses a blend of hydrocarbon and hydrofluoroether (HFE) in the initial ultrasonic cleaning stage and pure HFE in the subsequent ultrasonic and vapour rinse stages.

The final stage involves freeboard drying through solvent evaporation, aided by refrigerated cooling coils.

Gai-Tronics found this to be the only method to guarantee removal of all no-clean fluxes and associated white residues.

The whole process is automated with Kerry's Autotrans Mk4 robotic transporter which maximises throughput and helps reduce solvent losses.

Finished components are subjected to strict corrosion tests in the form of weathering evaluations.

The results of these assessments have been so positive that every PCB Gai-Tronics manufactures is now put through the Kerry system.

Kerry's ability to guarantee and demonstrate cleanliness levels, combined with a commitment to keep running costs low, ultimately led to the company being chosen ahead of alternative cleaning manufacturers.

Gai-Tronics' desire to minimise solvent loss, both for environmental and health and safety reasons, was another key factor behind the company choosing a Kerry machine. Request a free brochure from Guyson International ...
