For years all our R&D for high temp applications (automotive underhood electronics) has shown that Pb-free, at our max temps, doesn't have the reliability of SnPb. Fortunately, for us, EoLV (End of Life Vehicle) legislation in Europe was enacted bef

Hi, which kind of stainless steel are made your solder pot components? for istance : AISI-304 ? AISI-306 ? AISI-312 ? AISI-316 ? As we know AISI-316 will last more against Tin erosion. But AM SACX does not allow so much !!! I know who since t

Hi, We did this last year and winded up having to replace one of the contactors due to the frequency of up/down,up/down. Not sure what implications the constant on/off would have on the alloy after a while/ dross etc. When your pot starts up that

Sorry to hear that RDR. Although, I thought the statement was "drive" a Harley (not own), which I find funny. Also sorry to hear about the Vette too. Should we make it a rule that the guy with the biggest spoiler is right? Then we can make a movi

Good calculation, i have to say. Do you forgot, If you let the machine cool down during night, the rest-temperature isn't roomtemperature? right, dont you think the temperature will be something about 140�C ??? heating up time then is not 3 hours. m

Jeremy, Just started looking into this equipment myself. I have not dealt with Madell Tech however, I know that they do not manufacture equipment . . . they are importers / resellers of equipment made in China. To me the stuff on their site does n

No nitrogen generator. We have a service bring us nitrogen tanks every week and have the machine set up so if one goes empty, we can turn on the other one to keep a seamless flow of productivity. Our waves run from 6:00 am until 3:30 am between 2 shi

Grant, apart from troughput another thing to consider is boarddesign, If there is any SMD within a diameter (eg 3mm) of the connector you won't be able to solder them. I think those are the 2 main disadvantages of selective. That being said, for le

We now have an AOI in our process after printing and have noticed that all the small aperatures are getting clogged by solder paste. Mainly on all fine pitch parts. We are using Kester ws R562 SN63/PB37 mesh -325+500 90% metal. It was manufactu

I almost forgot; If the pcb have HASL (Non RoHS) surface finish, then big fine pitch QFP:s could be shifted during reflow, beacuse of the un-even pad-surface... We have been trough that scenario also... But step No.1 is to make sure that the componen
