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

Always happy to share information. Perhaps other viewers on this thread, can get some ideas of "how to". /Sincerely Ps. There is a so called "standard height" which the conveours/machines from different manufactories must be able to reach; without r

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

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

I am not using a solder pallet, I don't think the problem is contamination related, because these parts are on some of our other assemblies, and they're being waved with no problems. The problem seems to be mainly on our panelized boards for some rea

SMEMA compatability

Electronics Forum | Mon Mar 29 17:55:39 EST 2004 | gregp

What is the importance of SMEMA compatability regarding height of the PCB during transport? Most machine manufacturers ignore this and simply give you blocks to put under the machine if you need them. My question is if all of your equipment was des

Electronics Forum | Fri Mar 16 08:01:53 EDT 2007 | ck_the_flip

SAC coated leads on certain components require more dwell time. If you find that you have top-side wetting issues, slow the conveyor down a bit or increase your wave height, or, a combination of the 2.

SPC and Wave

Sure you can use SPC charting on the wave setup parameters to warn of impending problems. Examples of useful points of analysis are: * Dwell * Temperature * Pot analysis Certainly there's a range of other process controls that could be monitored.
