Exactly. Poor Olas is pulling his hair out over an issue that has no business being "standardized". The SMEMA guys with apparently way too much time on their hands couldn't simply stop at the communications protocol and leave it at that....they had t

You should not be worried about these points in the SMEMA standard. You need to make it work for your application. If you are running really small boards, keep the gap between conveyors and the lead-in as tight as you can. If you are using large pane

I have a couple of questions about the SMEMA conveyor (standard 1.2); I posted the question to them but had no answer. SMEMA says: 5) Maximum gap. The maximum gap between the in-line machine track ends is 0.375� I would suppose this gap refers to th

I am sorry for my poor english, but perhaps you will undertsand:-) The important thing is to get the conveyors straight: The front fixed rail must be parallel with the next one and also the heigt. The heihgt of the prior conveyour should be (but not

Most conveyors are sold by the inch. I allow for no more than one inch gap between the end of the conveyor and the next piece of equipment. If you trust your measurements, 1/2 inch is best. This will allow for the smoothest transfer possible of small

SMEMA is not just conveyor height. It also is Conveyor width, Edge Clearance, Tooling pins, Maximun Machine gap, and Lead in of conveyor. Additional, SMEMA is a machine communications Protocol for machine to machine or machine to conveyor communicati

4'2'' should be enough, going any higher and your bound for large gaps between machine and conveyor. Its been awhile since I set any up but i'm sure that 4'2 will be enough but not too much. I'm sure I wrote down my exact measurments, if I come acros

Received an info that the longer the oven the higher the throughput. What's the formula when calculating oven throughput ? say, i have the following: Oven Length : 266 cm Conveyor Speed: 29cm/min PCB Length: 29 cm Gap per Board: PCB Length x 0.5

We are designing a new in-line inpsection station for PCBAs and I am a little confused about how to interpret two the Mech. Interface standards in SMEMA 1.2 (items 5 and 6). What is exactly meant by "maximum gap"? Does this get at the distance betw
