Hello, On customer want to make a aluminium board. It will have SMD Led on it. Like I never "played" with this before can someone tell me what I know to know on that new thing. What kind of reflow profile we need. What just I be aware of, is

Sounds like you might need a firm with experience. Jade Equipment Corporation is ace with this kind of work having been a captive machine builder to IBM for almost 60 years. Here is a link to their corporate slide show. http://www.jadecorp.com/cp2005

I want to get a collective opinion from the forum... I was always under the impression that Humidity at SMT can be a disaster and can cause solder balls... But what about at the Wave/Selective solder? If every board or almost every board has solder

Oh, for a second there I thought it was 257 C, not F. Solder temperature! Still, one WEEK at 257 F seems way extreme. Maybe this is to bake out a part that has been underwater for a week. Is this a military part? I can't imagine any commercial-g

What kind of boards are they? Unless they are very simple boards, you won't be able to just replace every TH component with a SM equivalent. The inherent LCR characteristics of the board will change I think the normal way would be not to change the

Good points on both subjects. Not all who talk engineer speak are engineers. It depends on how shiny their shoes are. Delta T across any medium can mean a myriad of different set values. From Polynomial Expressions to the names of any organization

Aside from answering the obligatory "why on earth would you want to do this yourself?) pitches, you need to tell us more about what kind of packages (component body types....0201, 0805, QFP, BGA) are going on to the board, how many you plan on buildi
