Hi, I'm having issues with boards sticking/jamming along the line, as well as what seems to be excessive wear along the guide rails. The boards are an Alumina Ceramic material and the rails differ by machine, but include anodized aluminum, steel, de

I need to profile a single sided board thats width is less than the profiler. Is there a difference in profiles when one is completed using the rail conveyor versus just laying the board and profiler on the mesh conveyor?

Yes, there will be a difference. When the board is on the rail conveyors it is closer to the top heaters and farther away from the bottom heaters than when on the mesh conveyor. That difference will create different temperatures on both sides of yo

Yes, mostly. The computer just has a setting for which size frame it is in (66, 84 or whatever). The bearing slider is almost certainly the same, too, although the rails are a different length. As best as I can tell, my 1306/20 (which is NOT a III

We are running a Heller 1707 EXL reflow oven, but we have a temperature variation across the board. When the oven first comes up to temperature, the centre of the board is 10degC hotter than the inside rail which is a further 10degC hotter than the

Yes Sir, Dual Lane. Different terminology in different parts of the world. Germans and Chinese refer to dual conveyor systems as "dual rail". I guess I've been working with them for too long. I will look into CTI, although I was hoping to find somet

Is there a preferred method among printed circuit board assembly for accurately and quickly verifying the copper weight of a printed circuit board? I would like a tool and process that our quality inspector could quickly use to verify upon receipt of

You might have to replace both entire linear rails, and then realign the axes for orthogonality. It depends on whether they can come up with a rail/slider that has the same height as the existing one. Bummer that NSK has obsoleted that rail design.

A little more detail on our application: It is a large fixture (approx. 15" x 18") that spans the chain fingers in the reflow. It has several cut-outs and reductions in thickness to allow for better heat distribution. It worked well/stayed flat fo

jamm, As with the other answers you've received, I agree there will be a difference. The question is will the difference between the temperatures of the product profiled at the mesh belt put you out of spec when you run production on the rail? the ke
