Cosolvent cleaning meets military specs
A cosolvent cleaning system is saving PCB manufacturer Ultra Electronics over GBP 45,000 a year, while boosting productivity and consistently satisfying highly stringent standards of cleanliness.
A cosolvent cleaning system from Kerry Ultrasonics is saving PCB manufacturer Ultra Electronics over GBP 45,000 a year, while boosting productivity and consistently satisfying highly stringent standards of cleanliness Since installation at the company's Weymouth site, the Microsolve 450 has more than halved cycle time and completely eliminated the need for additional manual scrubbing of boards

Monitoring system reduces solvent waste
Kerry Ultrasonics has developed an automatic monitoring system which allows users of its cleaning machines to check the rate at which costly solvents are used during processing.
Programmable baths clean consistently
Kerry has developed bench-top ultrasonic cleaning baths which can be programmed to maximise the quality and repeatability of results.
Ultra Electronics has calculated that the new machine will take only 13 months to pay for itself.
As its customers include military, medical and electronics companies, Ultra Electronics' products must satisfy a number of different cleaning standards, including ESA, IPC, BS and Mil Spec.
During contamination tests carried out prior to installation, the Kerry plant comfortably surpassed all of these benchmarks.
The Microsolve unit removes flux residue and general contamination from a mixture of through-hole and SMT PCB assemblies.
The majority of boards are made from standard FR4, although some feature PTFE, and the largest measures 200 x 400mm.
The two-tank (four-stage) cleaning process begins with an immersion clean in hydrocarbon Promosol Topklean EL20A and 3M's Novec HFE 71 IPA.
This is followed by immersion and vapour rinses, before boards undergo a freeboard dry.
According to the type of PCBs being cleaned, the first two stages operate with or without ultrasonics; the boiling action and properties of the cosolvent mixture in the first stage, combined with both rinse stages, ensure that a high level of cleanliness is maintained.
Neil Garbutt, Quality Engineer at Ultra Electronics, outlines the reasons behind his company's decision to install Kerry Ultrasonics' equipment.
"When I came to investigate the various cleaning systems available, I found that Kerry offered the leading technology and felt that they could support our business in the future". Request a free brochure from Guyson International ...
