Hi All, What are you running for selective solder flux? I'd like any opinion on water soluble and/or no-clean fluxes you are using. In our Kiss 104 machine we use HYDRO-X20 water soluble flux, per the original install suggestion, but I'd like to k

Hello Armando, this is what I found into the handbook "Failure Analysis of Electronic processes" : "...Flux residues with water-soluble flux activators that are conductive and corrosive if left on in large enough quantities are detrimental. If you

Chemistries are limited for WS Mask. Try looking/changing other components, trying different flux types is easy, identify water cleanliness, is it ionic/no-ionic...probably is benign. Could be a plating reaction which is tough to investigate. Call

We are trying to build two different PCBs - one with no wash flux solder paste and the other with a washable flux solder paste. How difficult is it to use the same SMT line and switch between the two pastes? I assume there will be some cleaning invol

Thank you for your response. We build boards on an SMT line that is shared with other companies too and are currently using water soluble flux based solder paste on both boards. We realized an issue with washing on one of the boards so requested to

Have you tried an ultrasonic water cleaning process? We use an ultrasonic cleaner with tap water and Omega Aqua Clean LPH cleaner (omegasonics.com) then rinse with DI water. However, our cleaning requirements are not as strict as yours are from the

Hi, I could like to find out what are the things need to look out if I'm doing a new SMT solder paste ( water soluble & no-clean ) evaluation. And also flux ( spray type ) for wave-solder ( water soluble & no-clean ). Appreciate for all the input..

There are chemistries out there that will solublize some post-solder NC flux residues. I have had success with Zestron material Vigon A200 and Petroferm material Hydrex DX. Go to http://www.zestron.com and http://www.petroferm.com These are chemical

We are using a water soluble flux which requires the assemblies to be cleaned in an ultra sonic cleaner after assembly. Is there a standard that specifies how long the assemblies need to be baked/dried after being submersed in a water solution for a

Hi John, Are you talking about cleaning the pallets after running to store them? or during production? well in any case...I recently started to use this cleaning solution "Cybersolv" from Kyzen. It is water soluble and also can be used instead of IP
