Hey guys, I was wondering if there was a standard set of tests used to evaluate flux chemistries for wave soldering. For several years, we've been spraying Alpha 871-25A flux from Alpha Metals onto our printed circuit boards with relatively good suc

All, Current supplier of Solder bar charges for Pot Analysis to be carried out. �60 a go. They say that they get charged so they pass it on, With the imminent change over to leadfree this rule still applies. Anyone know of a Lab etc. in Ireland th

Omid, Your best bet would be to obtain and read the various machine manuals for the equipment that you have. HOWEVER, "programming" the reflow oven, (otherwise known as profiling), is product and solder paste specific and will most likely NOT be cove

If I have a leaded board (PCB) and the only component that I have to repair it is a lead-free BGA, what type of solder do I use, leaded or lead-free?

Dear Larry, I developed the ultrasonic cleaning process for Smart Sonic. It has developed into the most widely used stencil and misprinted PCB cleaning process worldwide. With that in mind, I offer some words of caution. "IT'S NOT THE ULTRASONICS!
