If you are doing double sided smt you need to look at a pin chain conveyor on your oven, not just a mesh belt. Regarding vapour phase I'm not an expert, but I've not seen one run with Nitrogen - as I understand it the vapour creates an inert atmosph

Dear Javi, Thanks for the feedback and review. Sorry i was bit busy. Yes the issue is minimised, but not eliminated. We have tried with reducing the vibration source in chain conveyor of oven. Our board is having parts very next to each other. O

AR Sounds like dirty chains... couple ways to check... Pull off the drive chain for the conveyor. Place a wrench on the (unload end) drive shaft and spin, if it is a bit tough.. dirty rails. Also look at load end of chains. The chain goes low and w

Hi all We have an Omniflo 5 (-97 vintage) with pin chain conveyor. Lately the chain drive motor has started to emit some chirping noises, as if there were a bearing running dry or something. Is there some kind of maintenance schedule specified for t

Make sure that your mesh conveyor drive chain is not jumping a sprocket tooth. This will cause the conveyor to "pop" and you will have skewed parts. I seriously doubt that it is your profile causing skew. It is more than likely something mechanical.

It is possible. If the talcum powder mixes with the chain lubricant, it could gum everything up. Back a few years ago when I was running an SMT Quattro Peak, I was having an issue with the conveyor chain drive motor going into overload. We had to pul

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

Asking the Grid Lok to flatten out the board is like asking the SMT Reflow Furnace to detab the panel. It was not designed to make up for the deficiencies of your fab supplier or your unsuported 1st reflow pass on the the chain conveyor. However, i

hello Diego, I would start by opening oven and looking for missing components. once you locate them you can work from there. are you using any alu caps on your board? I had problem with bad alu caps exploding in oven and scattering other components.
