Hi, We have recently purchased a Quad IVC 115 pick and place machine but are finding it difficult to place SOT23 and similar components. The Visual alignment system rejects the components. We have manually measured and also got the system to measure

Hi Everyone, I am in the process of selcting a new wave solder machine for our small company. We currently run 2 Technical Devices (18" Nu Era Jr. dual wave). I considered converting one to Lead free. It seems for alittle more we could have a machin

Billy, I have to disagree with you. We inadvertently soldered a Pb BGA with SAC305 paste and then had it micro sectioned and spectrum analyzed. Imagine our surprise when we saw the spectrum analysis showed Pb. The micro sections showed none to ac

You're a piece of work! Why don't you work for any of the major wave companies? So how does slowing the conveyor speed eliminate drying flux? And when you slow it down, what speeds it up to make you say "I lower the wave because I get shorts going

Yes, different pastes will cause ovens to become "dirty". I believe you are talking about flux build-up. I've switched from one paste to another based on sample studies, only to find an increase in oven cleaning. During most solder paste evaluatio

Hi Jay, I'm guessing that you have either: a) heated length of 64 inches b) a zone temp of 230C and not a surface temp of this magnitude c) Burnt pizza's 8 mins at 220C for a perfect non frozen pizza, however I find that the thermocouples keep fal

I agree that it's the probably the chain. The links get dirty and can bind up over time. When you pull the chain, check to see that each link rotatates freely with its adjacent link. I bet you'll find one or more links that are binding. This is the s

See Samir that's what happens if you go too lead-free seminars, they feed you crap. If they served you lunch with bismuth chips its time you see a doctor or you end up like WML. By the way any takers?? Who in this forum volunteers to be the first to

Pardon my ignorance on this subject but I gotta ask... When the SMT guys load partial reels, I'm told that they have to waste a few components in the process. It seemed obvious to me that there should be a kind of tape that can be added to the end

Hi I am using selective soldering to dip soldering the connector pins to the PCB and would like to know your experience: a) Is there a recommended dip or dwell time for the dip soldering? b) How do we improve the solder coverage in the TH? c) How t
