Steve, Let me try to give you a short answer to your question. A good book in soft soldering would talk about the excellent characteristics of leaded alloys and all the reasons why leaded alloys are very reliable. In short a good book would advice y

I have an application that requires soldering pieces of metal (copper plate and copper fins to make a heatsink). Each piece is about 1 lb. I cannot test it in our reflow oven (5 zone) since the piece is about 3" in height. Has anyone attempted to

The Immersion gold is not a problem with BGAs specifically but "black pad" which can be present anywhere. The unfortunate thing with BGAs is you cannot see it. Personally I hate white tin. It is okay for single sided boards running no-clean, but c

davef: I am a colleague of Sara at Foresite and we came to the conclusion that the solder balls were entrapped based on the minimal amount of information from the original question and the fact that the x-ray showed the balls and it wasn't mentioned

If you are talking about smt components I'd say absolutely not. If these are through hole components I'd say possibly (if they are in rows, and not a whole lot of them). The machine is slow, but the quality is great. Creating a wave profile takes abo

I do not have a ERSA Versaflow but do have some ERSA equipment. Only can tell you I will most likely not purchase anything else from them. The experience I have with their service after the sale would have to be rated VERY low. In addition, they emai

EdgeTech SMT Tech here. I was questioning the process our Engineers are using concerning Water Soluble solder paste. I have no experience with this paste. I was wondering what need so be done differently when using this paste. As far as I know the on

Agreed - D.I. a must. Also, operators will have to pay attention to lesser stencil life than no-clean paste. Product specs. might say the stencil life is similar but experience has showed us that no-clean last much longer and rolls for a longer tim

Hi, I curently have an interesting challenge. But I don't have all the knowledge to solve it. One of our boards is used in RF applications. We noticed that the No-Clean flux residue makes interferences in the RF signal. Removing the flux residue so
