Dis agree?!?!?! We solder plenty of them o6o3s at honda and they l00k 0k! Solder balls will always fall off the b0ard when mounted anyway.

All good points by Pee Wee Herman; your solder balling may appear if you don't currently have stencil with reduced apertures or "homeplate" design. "Flux is solders' muscle."

Does he look at the board under a Mantus and mistake vias for solder balls, get mad and walk away? Mine does.

if you are not using them for test points or want them filled with solder for current carrying capability then tent them puppies. i was able to move our company away from exposed vias many years ago and this eliminated lots of hairline shorts between

Hello everyone, thanks for the feedback. Now I am sure it is too much solder paste. It seems that the pads are a little bit bigger than they should be, so I will probably need an aperture reduction more than 10%.

We use teflon covered thermocouple wires. I can't seem to do a decent job of cleaning the wires to get a good high temp. solder ball on the tip between wires when I need to repair one. Any tricks to it?

we suggest as below : the first : check the soldering(solder ball and pad) by X-ray ; second: to do dye analyse (note:pls confrm is there have crack )

Have you checked your reflow profile? You need top make sure that you are with the specification of the solder paste. We currntly use the Kic thermal profiling device.

Try Easyspheres (Kester), or Q-Pearls (Qualitek), or Alpha. They all have solder spheres in that alloy.
