That link doesn't work for me. From the more you explain - it does sound like an issue I've had in the past on a few different builds. In the end we traced it to a fault with the paste (they were having mixing issues in the chemistry) but they as y

Tuan - How about Sn/0.7Cu? It's M.P. is 227 and it's readily available. If the leads are Gold plated you might consider pre-tinning them. If you need a higher temp alloy any of the major solder companies can help - I suggets you start with Ind

Tuan: Consider Sn 96.5/Ag 3.5 or Sn10/PB88/Ag02 also. As Glenn says, you had better get rid of that gold or you will never have a shiney connection. Not that a shiney connection means anything about the quality or reliability of your soldering. M

Glenn and Paul have hit the nail right on the head. Continue working with your solder vendors. I know that many people have succeeded with what you are trying. And the Pb-Free push is only making things better for you as companies develop just wha

If it works for you, great. I would be concerned with "usually very obvious". Not all solders respond like you might think (rma's, OA's, NC's). Yours works. Mine may not. Do you control your facility humidity? I find that common sense is not

Hello Ok there is not much info here. What you have to mae sure of is several key factors. 1. Have you entered the correct stencil thickness. 2. Are you using the stencil gerber (not the paste layer) The paste layer is usually not adjusted for ap

Now is when you find out if you have a good sales rep for your solder. I've seen solder reps eventually get around to responding. And I've seen some that would be in the plant that day to help you out. I even know a couple who would give advice even

I've tried Indium NC-SMQ92(96.5Sn 3.5Ag) on these MCMs and achieved only marginal wetting on pads and parts. The good wetting is what I try to achieve, shiny is what my engineers want (Prototype environment). Does pre-cleaning the PWBs in ultrasonic

Grant, I also have to say that the microwave thing is the coolest thing I have heard lately.Hahahahaha!! ! Here in the U.S. we have these comical Foster's beer comercials that are really really funny. I kept having flashes of those when I read this

Hi, There are "Fluxbuster" or "Rotator" pins on the market - we had to use them a few years ago on a flexy board (with OSP). There is some info from one source at the following link: http://www.isiconnectors.com/mfrs/idi/idipr.htm#Rotator We got
