we also have a need to measure the solder bond strength of our gull wing parts on our pwb. there are many published comparisons between eutectic SnPb and no Pb solders out there. the number that comes to mind is about 10N to 15N. I have not looked

Hello, I have recived from customer PCB where he found that big SMD electrolytic capacitor just fell off. I checked this boards (FR4 , Au/Ni coating). I noticed that all solder remained on the termination of capacitors and looks ok but on the boar

Continuing, I�ve optioned about the uselessness of shear testing of solder connections on this forum previously. So, the points that you make about the elusiveness of developing a standard for measuring solder connection strength is well taken. I�l

If there is a way to pre-tin the parts, that might help in forming better joint with gold.

We had a solder joint problem in gold plated PLCC68 ic. We do double sided reflow process with Cookson OL107F paste. First we do top with paste and second with glue process.The solder joint shape and wetting looked normal.In the process of testing

The reliability of a Gullwing component solder joint is in question when insufficient solder is evident: *at the heel of the lead *at the toe of the lead *none of the above

Hi... We tend to do a lot of footprint calculating for new SMD components. But what about the amount of solder paste on the solder pads. The amount of solder alloy is of cause determined by the stencil aperture size, stencil thickness and the sold

You can use the IPC-7525, Stencil Design Guidelines for start up.
