By any chance is it eutectic paste and pallidium leads? Also how tight are you checking coplanarity? At least with the MPA-G3 you can check so tight that any IC will fail in the real world. Or you can check so loose that you might as well not check.

Your profile is definitely off. It could be bad leads but it sounds like your max temp is too low and the TAL is too short. By how much? Don't know.

It's a no clean paste. Yes it's a single lead (sometimes a few at random locations) and i do notice that corner leads (or close to it) fails more.

Thanks for the input Guys Yeah the not so knowledgable customer does not like to residues for cosmetic resons. The flux is for lead free process, of the no clean and water soluable type. We have explained to him that technically the residues do not

Hi Samir You are spot on. Exept the glossy surface. For us exactly the oposite. Who is Wavemaster Larry? Smartasp

Larry is an exponent of Newton's third law - the law of reciprocal actions. You've no doubt heard of the font of all knowledge, well Larry is the equal & opposite of this. (There has also been considerable discussion as to whether he has his own su

Consider using 100% nitrile gloves or finger cots. They are ESD safe and will not break out the skin like latex will. Cotton can absorb flux, solder, etc and will leave a lint residue however it is considered ESD safe.

Dougs, Make sure they use the same solder that you plan to use. In my case they were unable to get acceptable solder joints with our solder. We use no-clean P1 flux in our cored solder. So I recommend you try before you buy. Jerry

I also heard that fluxes are more agressive in lead free alloys. Try maybe to clean your tip more often ?!?!?
