Guyson Microsolve 250 Pixels 350 2C

Aerospace companies looking to eliminate the need to use n-Propyl Bromide (nPB) in the defluxing of their PCB boards and panels can call on leading industrial finishing equipment manufacturer Guyson International for an effective solution to their cleaning problems with the installation of a Kerry Microsolve Co-solvent cleaning system.

At present many PCB panels are still being cleaned using n-Propyl Bromide (nPB) – a solution that in 2012 the European Chemicals Agency (ECHA) listed as a ‘Substance of Very High Concern’ (SVHC) and now n-Propyl Bromide is classified as a CMR product (Carcinogenetic, Mutagenic and Reproductive toxin) by the SED (Solvent Emissions Directive 1999-13-EC). This has resulted in many users having to reduce their nPB fluid consumption volumes or replace nPB within a specified time period.  Any company searching for a safe and effective alternative for cleaning their PCB Panels can now come to Guyson for the solution.

Guyson’s ‘Kerry’ branded Microsolve Co-solvent system has four process stages comprising of ultrasonic cleaning, an ultrasonic rinse, vapour rinsing and finally freeboard drying. The co-solvent process defluxes all types of PCBs, assembled and reworked, removes no-clean solder flux residues, and can also eliminate the white deposits (dependent upon flux age) associated with traditional single solvent and water-based detergent processes.

The Microsolve has well proven and established unique solvent retention features which provide economic benefits through the efficient control and use of HFE solvents. Microsolve owners enjoy low, predictable running costs thanks to intelligent machine design - a highly effective refrigerated reflux cooling system, vapour break and an increased freeboard zone all help to prevent the potential high running cost through minimising evaporation of the HFE solvent. 

Cleaning trials

Prospective users of Guyson ultrasonic cleaning equipment are encouraged to submit sample components for free feasibility testing in the company’s extensive demonstration centre at Skipton, England.
