Larry, Yes, no matter how much you�d like to avoid using NC, you probably will have to start using the stuff, if the design [sales, in your case] types have their way. We can clean WS under 1mm and 1.25mm pitch BGA. For 0.8mm pitch BGA, we use NC.

Posting here because all the threads asking for feedback on it are locked. We have been extremely happy with the 4300 tacky flux for BGA attachment. Not only is it both washable and no-clean (i.e. wash-optional), it was also the only tacky flux tha

Solder paste used was Kester FL250M (no-clean).... components affected were only chip components 0603, no BGA & no IC components.

OK� Nap time�s over! Technically speaking, water soluble flux is just that, soluble in water. Technically speaking, one does not need a saponifier or any other chemical agent to remove water soluble (OA) flux residues. However, one must conside

We are planning on using a chip that is available in LGA or Sn/Pb balled BGA. The package dimensions are the same. Pitch = 1.27mm. We are using a Sn/Pb soldering process and no clean paste (wash afterward) for high reliability Class 3 assemblies. Fai
