If what you say is accurate, two thing come to mind: * Pads on the board are incorrect for the tombstoning components. * Profile is different on the individual pads of tombstoning components. We have heard of, but never seen, components [tants] that

AIM has an article that includes anti-tombstoning solder paste information. It's called "Reducing The Tombstoning of Small Discrete Components" and is located at http://www.aimsolder.com/technical_articles.cfm#14 Or I can send a copy to anyone inte

Sarag, FYI tombstoning is a functional failure. Tombstoning is where one end of the component is not soldered and is in the air above the board/solderjoint surface. You may be thinking of billboarding (part on its side with both ends soldered down)

GEB, The parts that are tombstoning have all ready been through reflow once with no problems, so I assume the paste and the positioning was correct the first time, since they did not tombstone through the first reflow. This is very strange.

Many factors will make tombstone happen. from design/stencil aperture/soler paste/placement/reflow and so on. here is one article about tombstone which I prepared long ago. send me your email if you need it.

Hi, Im having problem on tombstone, The part is LF chip component 1005, and my solder paste is WS leded. tombstone is not in a deg angle but one side is soldered but the other side is just sitting on the solder. Looks like my solder can not wick up t

Try rotating your board 90 degrees when running it through your oven. Will probably solve the tombstoning issue on that cap but might cause tombstoning elsewhere.

I�m also having this problem with Panasonic film capacitor. Even when I have the correct pad size according to Panasonic data sheet the tombstoning occur. I am thinking that the problem could be the plating of the film capacitor. The only way I could

I can understand the theory behind fewer tombstones with SAC. If people were having tombstone problems with SnPb eutectic solder, often switching to Sn62Pb36Ag2 would improve it, because with the addition of some silver, a small plastic zone in the
