I have a through hole product that is currently built with HMP solder(93.5Pb,5Sn,Ag1.5). We then dip it in 60/40 SnPb to give a solderable finish as HMP tends to oxidise. We need the HMP as our Customers solder through reflow ovens. Some customers w

Technically speaking, most likely yes it will work, unless possibly it is a BGA. There are issues surrounding BGA's. Here are some of the general issues: On any type of component, if the Pbfree solder you are using contains bismuth, then the Pb in

lead-free processes involve higher temperatures. if you run this PCB thru the reflow oven, the worst possible scenario is that the board may melt and deform. even if it doesnt, it may delam internally (and or the bare board reliability might be compr

Yep. If speed is not an issue a Heller 1500 will pretty well do you fine unless you are trying to process a brick. A Heller 1700 will not give you any more heated length, so don't get sucked in to that one. However, they are a little more fun to pl

Although greatly publicized and many papers on the subject, I wish to hear experiences from the field from professionals who have migrated from SnPb wave soldering to PbFree wave soldering. I am being pushed by one of my largest clients, an internati

CSullivan, On the great SMTNet archives, there was much discussion about how to run in this scenario. Here is one such thread: http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=10483&#Message42337 Also, I wouldn't "

Yes, this scenario is fine. However, BGAs are a different story since the ball is the bulk of the solder joint. In this case, you MUST run a "hybrid profile". Look it up in the fine SMTNet archives (keyword: hybrid profile). I have "been there an
