I am trying to put a center support on a wave solder machine for lead free soldering. My problem is that every metal I use is interacting with the lead-free metals and thus eating away the center support. I have tried titanium, stainless steel. I am

How about graphite coated wires or bar? If there are such things

I would try a PTFE (Teflon) wire or Teflon protected wire or you could try anodized aluminum. Its getting more and more interesting how the lead free era develops. Just a thought I wander how long its going to take the tin (not passivated with lead)

Check for anything that may contact while activating Z tower (support, wire, connector, etc) I also saw one day a lost PCB causing that kind of problem ?!?!?!?

We have acquired an UltraPak 600C wave machine and are investigating the possibility of installing a centre support wire conveyor to eliminate the use of pallets. What is involved in this project and how feasible is it? The boards have bottom side SM

You're going in the direction of fab improvement, a great direction. But in another direction; If you're already in a carrier, how about using a skyhook of some sort to support the middle of the fab from the top side? In some cases you can put fine

Might want to check to see if the weight of your part has increased. If it has increased, you may not have enough surface tension to hold the part on the board. I am assuming you already checked that the component isn't getting hit by something in

Yup, that sounds right. I did try one with red on top on one side and white on top on the other side. Oops, blew a capacitor out of the back of the base. If anyone else Has these, here's how it goes to make them work: Top pin on both sides = +12V

| | We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centr
