We finally can't avoid adding wave solder to our process anymore. For lead-free, medium sized wave I'm leaning towards mid 2000s senju units as the best fit. I've never run their equipment. Opinions? As a point of reference for our general capabilit

The current discussion about solder fountains has to do with copper dissolution. Broadly, copper dissolution is the weakening of copper traces where a trace and a barrel plating intersect due a loss of the copper into the solder. Longer contact time

Hello: We have used our Phillips Topaz on a number of volume jobs and been very pleased. A while ago it became apparent that the vision LED's were growing dimmer as evidenced by having to adjust light intensities upward for various components in so

Wondering if anyone has ever run across this in their travels. We have gotten a few field returns back in recent months and it appears that many of the balls of the PPC440 CPU BGA (ceramic) have shifted. I know we Xray this part 100% during assy so

We are using our selective solder machine to solder a backplane with sixteen (16) 4x48 pin 0.080" connectors. Our first pass yield is about 85% meaning that 85% of the connectors come out with no bridges. Not quite as fine pitch as your connector a

We have two ZipaTec 460s Selective Solder Machines, one for Lead and one for Lead-Free. This morning we noticed the solder pot was covered in solder balls, and after asking the operator what they had run, the answer was "Nothing." The operator had al

We have a Versaflow 40/50 and ours is setup like this. We have out nozzle test position set so that in the Z axis you are 3.8mm away from the pin. Used feeler gauge Then you can set your gradient per nozzle. Start with a number then do a wave offs

I think we are all on the same page with this one. Since you ran from 96 until now without any issue I'd say that now you know what causes the problem, make a note of it for next time and move on. I have found with our older machines that "if it ai

We installed a Soltec Delta 3 a few months ago and have been trying to run with a VOC free no clean. We're using SN100C in the pot. We are spraying the material and have top/bottom preheat. Evaporation of the water in the flux is a bit of a stru

I have an Ersa Versaflow selective solder machine (single bath) which runs via a Profibus control system. I have checked all of the settings on the inverter, and all of the connections and outputs throughout the machine, but the machine returns a 68
