Hello Steve, Yes, there are differences in the various alloys and I have described briefly below these differences: SN100- a common name for 100% tin that is used to increase the tin content in 63/37. SN100C-Name for Tin/Copper/Nickel/Germanium all

Open the rear door that has the cooling fans on it. Look at the wiper blade regulator, look toward the front of the machine about 8" or so and to then left 3"or 4". There should be a lexan cover/box over the board that has this pot. on it. If stil

Good afternoon! Typically, we normally recommend testing the pot, and adding either Sn/Ag or just Sn to keep it at bay. One nice thing about the solubility of Cu in Sn based alloys is that it should reach a theoretical upper limit of about 0.1%. I

Anyone have any experience with Displacement Soldering? We just came across a benchtop displacement soldering system, and I'm wondering how effective it might be for me. We're currently looking at a "best" solution for us right now for lead-free

No, not exactly. It's sort of a one board wave/pot assembly. Looks like you put a board in the chamber, it has programmed preheats etc, and when the preheat time has been reached, the solder is raised up to the board, the board is soldered and the

radiant heat. 137c The hollis was a great machine. The one I had the prehead wass on or off there was no setting. The pot temperature guage was brocken so I had to guess and manually turn the heater on and off. The whole machine was covered with 1 i

In passives I dont know if anything changed at all other than the terminal plating. As for Active components there has been much engineering done to allow for the extra heat needed to liquify say SAC305 or other lead free pastes without damage to th

Never heard of "special finger marker stickers" for checking wave parallelism. We assume that you're talking board-to-wave parallelism. We use a Durostone fixture with a thermalcouple [TC] in each far corner of the fixture (flush to the bottom of th

We do very little wave soldering, maybe once a week. We have been running a Novastar Spartan 8S for years with very good results. I do wish we had the wider 12S for the wider boards, but it has only come up once in 7 years. I think there is a lot

I agree with RealChunks. The application of any of these "wave solder process control tools" is dependant on how the shop is run. At some shops, PM is inconsistent and slacked off on. At other shops, there is no technical expertise at the operator
