Steve, Water-soluble fluxes are per definition very corrosive and need to be cleaned (read the data sheet) Encapsulation will prevent humidity reaching the water-soluble acids but will not prevent reducing the metals the flux is in contact with to m

Hi everybody, Is there any criteria as far as No-clean flux residues surrounding solder joints when using selective solder machines? I have a Novastar SPA 400 and use flux NC kester 959. If I decrease the amount of flux, then I experience problems w

Hi, We are planning to use RMA flux based Solder Paste for our line. We are currently using a No-Clean Solder Paste. Can I use an aqueous cleaner to clean my board with the above paste ? How will I clean the board ? What are the advantages and disad

Considering all the constraints you are faced with, I would try changing the apatures for that part on the stencil. It seems as though a no-clean "homeplate" appature would put less paste on the board. Less paste means less flux, and it might be en

Hi Jeff, Sean is correct. Although ultrasonic technology will work in post-reflow de-fluxing applications, you will receive concerns regarding ultrasonic �damage� to wire bonded components. Much has been written to combat this belief but the conce

Too many hands in the bucket, unless the owner is one of the engineers. Typically flux is not rated or classified by "feel". What are you soldering? Wires? Components to PCB? What is your cleaning capability or requirement? Aqueous? No-Clean? Ul

This is a real problem. We have experimented with a number of off the shelf products as well as discussed the issue with a few solder manufacturers. As you are aware IPA or Flux off can make the product look worse. I would discuss with the custome

saturation occurs at ppm levels. Remember, IPA is extremely flammable and its bulk use makes the plant liable to all sorts of quite repressive safety rules/regulations and so on. Ignoring these rules exposes the owner to fines and possible plant cl
