#40 or #41 are very common chain types.

Try Flip Chip Technologys. They have several daisy chain flip chips. One is called FP250. .250 X .250 solder bumped flip chip. Try Technet too. Remember seeing several other manufactures of daisy chain die. Maybe Unitive at www.unitive.com can

Be careful on how you go about this. Some older wave chains will have anywhere from a bit to lot of lead embedded into the grease. Ive had best luck sending it out to a shop that can hot tank them. Costs about $25 and it comes back all clean and lube

we keep some extra chain belt that is used in most washers and reflow ovens. We have not had any problems. Our wash has slightly more pressure comming from the top nozzles than the bottom nozzles. same for the air. This will hold the boards down in t

I've never had this problem on an Omniflo oven, but have seen it on others. It has always turned out to be mechanical. A bearing going bad or FOD in the rails. I would pull the chains and carefully check each link of both chains, all of the bearin

We had the exact same problem on our OMNI 10. We found that two of the rails the pin chain rides in were warped. Somehow at one point our PC lost communication with the oven and the heaters went wide open for several minutes...this is what caused th

I had the lurching issue...turned out I needed to readjust to cog wheels on the exit side of the oven. The cogs had slipped, and the chain was actually getting caught in the teeth...to the point that as the wheel turned, the chain would stay in it i

Common problem. Start at the Encoder and measure the 5v square wave. Trace it back to the Frequency to Analogue converter, then to the controler. I assume that your conveyor is in good shape. i.e. With the motor disconnected, the chain should flow f

The machine has been giving me trouble as the components are frequently lifted off the board and falling off as it goes through the conveyor. I am trying to remove the conveyor chains hoping to re-balance them. Is there a way to remove them and adjus

I would guess then that it is either variation in paste volume (unless you are using an inline SPI), or potentially a damaged chain or sprocket causing a small jump. The second one is easy as you can watch the chain do a full rotation, the first a b
