I have been working on Pb-free assemblies of screw terminals (terminal blocks). Unlike, other pin-in-paste conducive components, these component has square headed leads. We have been facing issues with the solder dripping into the oven. We were able

We know nothing about your: * Solder alloy * Materials of your board * Materials of your teminal block * Process setup of your wave * Wetting condition of the board or the terminal block ... but we'll take a guess anyhow. Tin-copper based solder all

Had to adjust more finely the timing on the soft push and the down stroke for insertion. I added flow controls on both input of the respectives cylinders with enough success to start production. This way, the soft push is late enough not to screw the

We also had this problem and found similar results with the anti-backlash nuts binding. We went through the process of cleaning the lead screws and the nuts which resolved the problem for about 6 months only to have it return. We learned that the

I have checked the lead screw and guide rails. There is't any apparent damaged to any one of them. I was hoping it be the guide rails because they are much eaier to repalce than the lead screw. If I start messing around the lead screw, It would requi

We use the following stuff from "Biral USA": BIO30 Synthetic High Temp Oil � Chain Oilers NMG-400G � No melt grease - miter gears/lead screws AS500ML � Anti-size spray - lead screws, drive sprockets, rail support L-brackets It seems to work good

Not sure how the lead screw drive gear is locked in place but is it possible that it's slipping in both directions (when driving the rail both forward and backward) and then not catching until after the other end has already moved some? You could h
