Does anyone have any experience with setting up a nitrogen supply system to a wave solder machine that is equiped for it? Does the nitrogen need to be room temp or higher? Does it make a big difference with bridging or solder quality? We bought a use

We dont have the debridging knife. I had one on an old Hollis machine I had once. It was totally worthless. I am setting up the nitrogen today. I will let you know how its goes. We are using a water based no-clean. The nitrogen will probably make a

We allow people in our shop to take calls on their cell phones any time they get a call, thinking that in case of an emergency they should be able to respond to their family's need for help. We ask that people close their calls that do not require i

Make sure your epoxy dispenser is repeatable. DO an experiment , inspect every board to verify epoxy is there before the part is placed... Is there an epoxy residue left on the PCB where the parts fall off after wave??? We do the epoxy paste proce

Hi Locktite is telling you to cure first, maybe for a good reason. So the epoxy becomes stable just before solder reflow moves stuff around and around and then settles. A WEG yet if you did some cross sections and analysis you might find piles of

Hi Up above in his operation / process description after a call to Locktite and then my note and then your note, we may have found the problem. One never knows at a distance. It appears he is striving to do soldering/reflow first and then concurren
