Same happenend to me with another flux some years ago, to me its a reduced viscosity of the flux, what I did was to reduce the width of the slot on top, where the flux exits, reduced the distance from stone to pcb and filled the flux reservoir to the

Dave has stated the caveats well. I too have similar experience in reworking BGAs that mirrors your own. The only situation where I saw this as an issue, was in memory devices where a row of BGAs might share a commonm heatsink. In those cases the

Have been through the same problem with the eurostep cards. The missing communications with the cards, suggest that some acid leaked from the batteries have etched tracks/and or the serial converters (soic8) on the cards. In all cases, clean the card

I agree that class III is overkill for most applications and the customer needs to pay for it if that's what they want. It's also true that class III doesn't assure things won't fail. Life expectancy is mostly due to component and material selectio

I am happy that you work in a shop that can build boards right the first time on a consistent basis. Unfortunately, I would say that every place I have been at, we have had a hard time meeting class III standards day in and day out without some kind

I did not mean to imply building to class III would prevent failures. Since there seemed to be a little confusion about the classes I threw that out to show that class III was a higher standard. I also agree that while re-work can fix a class III d

I used Indium WF-9940 at the last place I was at for 5 years. We ran leaded and lead free product in our ERSAflow selective soldering machine with that flux type. It worked good for both applications. The place I am at now we have an Ersaflow selecti

Hello, I have recently obtained a trial version of Mentor Graphics' BOM Explorer. Has anyone had any experience using it? We are currently editing our BOMs manually for P&P machines programming. After quick look and trying few options it doesn't see

The conveyor is programmed to turn off the belts and go into an error condition after 30 seconds if the board has not passed the output sensor on the conveyor. The intent is to indicate a board jam and prevent damage to the board or belts. On convey

As far as the buttons go, White = pause for inspection when depressed, lit when active Green = pass after inspection when lit you need to press the button, when flashing its waiting for the upline machine, Yellow/orange = when flashing indicates
