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

There is two major BGA coating camps. * Camp #1: "We require the coating to be under low stand-off devices but with no filleting. So we apply a thinned dip coat first, and then top-off with a proper spray coat" * Camp #2: "We want no coating under th

Fred: I'm tryin' my darndest to be good, because, for whatever stupid reason, I feel that you're making an honest inquiry and not just floating something to find the biggest sucker. If only Earl was still here, he'd always bite on stuff like this.

Q1: Can anyone explain to me about the effect of their mixture. A1: What is their �mixture�? Q2: What enhancement does my BGA will have when using a WS paste flux with regards to corrosion, 25 years life cycle of the solder joint. A2: Tough to say

We agree with John. It's possible to clean under 1.27 and 1 mm BGA. These devices have a reasonable stand-off that allows cleaning of water soluable flux residues with modern cleaners. So, if you have process problems with low-res fluxes, what mak

Hi Dave! Yeah, they've been around a while, and they're pretty straight foward like you said. About the only things that I can think of that I've run across that causes problems with these guys is when they're used on the bottomside of the board

What low profile components are you dealing with? We have had problems with cleaning under leadless chip carriers using an aquastorm 200 with Kyzen Aquanox 4520T and the general concensus is that you will not clean under this type of device with an

Shannon, We have been using VP for all of our lead free production since 2007. Here are the items I can think of off the top of my head. Pro's - small footprint, minimal profiling needed once machine is understood, oxygen free soldering process, s

| I am examining cut & form PTH component prep equipment to help in our manual PTH insertion process. We need the ability to process both axial & radial with snap-in and stand-off capability. Low volume with the ability to feed bulk, T&R, or Stick. |

Successful solder paste overprint is a function of the solder paste rheology, solder mask and through hole component stand off. * Solder mask with a high surface energy will permit a larger overprint than a solder mask with a lower surface energy. In
