| Hi there Chris! | Are the leads you talking about fine pitch? Is the complete fillet attached to the foot, with it being cleanly separated from the pad? I bet if you look at the board there will be via's really close to the pads at the location

| I am looking for the Industry standards on vias. Are they required to be plated with solder or is copper plating enough? What about reliabilty with either one? Also, if tenting the via is required should it be copper plated or solder plated over

Hi Jason! I can probably find something documented for you, but the easiest way to convince your QA people is just to show them. If you have a board around that has some 1206 locations all in a row, print the board with paste and then plac

Ryan, Please consider the following: There is no such thing as no residue flux. Low or no solids flux contain "wetting" agents to help the stuff stick upside down! Try painting your ceiling with less than 2% solids paint!! With all this excess liquid

| I've never seen this before. Today, I got this tombstoning on Tantalum Capacitors (Okay, I saw that before) | Here's the part that seems weird to me: | -They didn't tombstone onto a termination - they went onto their sides! That's right, both ter

Justin, Thanks for the response to my dilemma. For once it's not just me! The parts seem perfectly solderable, but I will try the modification to the profile you suggested. I wonder if the retention clips may be letting loose from the holes they a

Jeremy, I'm gonna make a couple of assumptions by "reading in between the lines" of your email: 1. You're using no-clean paste. 2. This is only happening on the second side. You tell me if I'm wrong about this... First thing, if you're only experienc
