Have you looked at water soluble no clean fluxes e.g. Multicore MF300? Neil Neil Atkinson - Quality Manager Stadium Electronic Controls Division(UK) -----Original Message----- From: Grant Emandien [mailto:[log in to unmask]] Sent: 15 August 2001 10:33 Subject: <No subject given> Hi all out there, One of our customers is concerned with the level of flux residue (no clean) present on RF boards - concern that the flux characteristics negatively affects circuit perfomance (FR4 material, HASL finished is being used for circuitry operating at 5GHz). He has thus requested to rather assemble using water-soluble flux. With water-soluble flux of course comes cleanliness issues which may result in latent defects due to entrapped corrosive flux residue. The product is spec'd to operate, uncoated at -40deg.C. Any insights into this dilemma? Thanks in anticipation.
