1. What is the method for declaration RoHS for material like IPA, FLux & Solder paste. 2. What is the allowable limit for RoHS compliance for the above material?

Alpha UP78 was a modern solder paste. Check with your supplier for recommendations. You're are cleaning some flux residue with the IPA and reducing the leakage current. We're not wild about using IPA. Problems with IPA are: * IPA / material being

Several things to check are: * Ask Multicore if their flux res and your conformal coat are compatible. Conformal coats and NC flux res are notorious for having compatibily issues. * Conformal coat a bare board to determine if there is there is enoug

its spray fluxer we deassemble the nozzle clean and reassamble again. flux tank also clean with IPA. ya same problem in all product plz find the attachments about flux

Hi Soza: As Dave F mentioned, there are lot of factors involving the formation of residue, after cleaning. Factors, (such as: solvent's cleaning power, presence of metal oxides, type of soldering flux, etc...). One thing pretty sure, IPC is usually

We know nothing about Envivar UV 1244 and you weren't real clear about the details of the problem or the materials [eg, ws flux, solder mask, etc], but we'd speculate your adhesion problem goes back to the cleanliness of your board. First by 'alcoho

I would advise against using IPA for stencil cleaning It may initially seem to produce good results but the way it works you end up with more problems. IPA is good at removing liquid fluxes but it dries out and cements solid fluxes to the stencils

At the OSHA training institute, our instructor stuck an electric drill in a bucket of water to demonstrate what proper grounding will do. Personally I wasn't going to try it. All our fluxes are no-clean, and are IPA based. Granted we used aqueous

We used Loctite 3609 and never had problems. If memory serves me isn't 3606 a screen print adhesive? First thing I would check is the cure profile of the adhesive. If it doesn't develop full adhesion, could be problems. Nuther question is are you
