Density is an "implied" measurement to determine activity. Most flux suppliers can sell you a flux acidity (activity) measurement kit. I used one from Multicore a few years back. We used it once in the morning and once after lunch to monitor no-clean

Well thats what i was thinking of doing and i am not worried about the designer of the PCB. He truly is a dick and i have had many fights with before about wave soldering pad sizes yet he insists he is right but i change them anyway and send the orig

Hi Russ, Just a quick note to you the assembly houses, You say your transition will be the easiest, I would have to beg to differ after working with several CM's and working with there Wave solder lines and finding compatibale fluxes that will work

I am based in Nogales and I have also tried the MS2, I was told to immediately cancel my trials, It did reduced the build up of dross but the mess it made to the wave and the surrounding areas was very bad, Everything was coated black and the smell a

All of us wave solder FR4 all day-long, not to say we have never had problems doing it. The selection of the laminate material should depend on the burnin application. We'd be concerned about a FR4 burnin board that saw GT 150*C for extended period

Grant, Newer lead-free fluxes have 6%-10% solids content - more activator, therefore leave more "visible" residues. Old technology tin-lead fluxes got down to as low as around the 4%-6% range (I'm going off memory, so me might be wrong)... You'll

Jim, In a previous life, we built some flex circuits for a customer. The configuration was a flex cable, with a circuit at one end of it. We had fixtures made out of the same material that we had selective wave solder fixtures made from. Cut an i

Hi, which kind of stainless steel are made your solder pot components? for istance : AISI-304 ? AISI-306 ? AISI-312 ? AISI-316 ? As we know AISI-316 will last more against Tin erosion. But AM SACX does not allow so much !!! I know who since t

Grant, apart from troughput another thing to consider is boarddesign, If there is any SMD within a diameter (eg 3mm) of the connector you won't be able to solder them. I think those are the 2 main disadvantages of selective. That being said, for le

Well, Ray Rassmussen believes that "IT" may put China on it's ear. Not sure about any of you, but I never felt the need to splash water on my face whilst reading this white paper. Hate to see how he'd react to seeing a board going over a 500 degree
