Hi,, My doubt is regarding to the Reflow Time, I mean, in a 5 or 7 zones oves, how long the board should stay inside the oven to complete the soldering cycle? 4 min, more, less...Should I keep low temp until peak for a long time or high temp in shor

As an alternative theory to the boards being damaged in the wave soldering process, it's possible that the panels are being handled in a way that flexes the panel and breaks the capacitors. In this possibilty, we'd expect capacitors in specific loca

Your process makes a bigger difference. What I have seen is ICT done early is better than AOI done more than a half shift later, and AOI done early is better than ICT done more than a half shift later. For high mix/low volume, I would go with AOI whi

Hi. I was curious what some common accept/reject criteria would be on copper wall thickness. For instance, if 1 ounce copper is used, I believe the IPC specification is 0.001" minimum thickness. Should the order be rejected if there is one measure

I heard from Electrovert's engineers that the SnCu alloy has a really tight process window and is not very machine friendly. It is pretty much used exclusively by the consumer electronics folks. They�re always pinching pennies and are running, lets s

I saw this MS2 in action at APEX on my friend's lead free wave during the show. Very impressive results. Appeared to simply pool in one specific location at the end of the pot...away from the wave completely...although I wasn't sure if this was due t

Took your advice Sara, and did contact PK. Got a data sheet that says "no residue on boards or components". But not done with concerns just yet - for example, if the MS2 becomes thicker and more viscous, what's that doing to my pumps? Unfortunately n

WELL I heard rumblings from the engineering dept that they wanna try this stuff here at my place of emplyment. Im not so sure about this.I've always herd that dross is part of the solder joint and part of wavesoldering.As I said before Ive done this

We are using 5 Mirtec's. Easy to program and debug. 1 in SMT. 1 in Lead Free and 1 in Thru Hole. I can't comment on the Yestech but we have had increadibly good luck with the Mirtec's With AOI's the proof is in the pudding. Arrange a Demo with your
