Hi Vijai, You didn't say if you were running Tin/Lead or Lead Free. For lead free soldering I would suggest that you try to achieve as close to 7deg conveyor angle as you can. John

Lead free solder does tend to resemble cold solder joints after processing. Generally, this is acceptable. The latest IPC 610 has pictures of acceptability of lead free solder joints, which you can use to compare to the joints that you are seeing o

Target those specific parts/leads with a thermal-couple and a mole and try to get the peak reflow temps up to 225 C. It's not a cure but it will improve the apperance of the solder joints.

You need to find out what is not compliant about the part. Also some parts can be compliant even though they are not stated to be. Even if the leads had a tin lead finish it may not be enough to make it not compliant. Anyways there is not any body in

Hege, Yes. Good info. We have other products that run lead free process with known non-RoHS compliant components. All of these are using LF process compliant fabs however so this is the first time we have been in this position. Thanks.

Yes. You need to educate your customer... On a side note, hopefully these boards hasn't gone through wave over your LF solder pot.. This will contaminate your solder pot and won't be cheap to fix it.

Bronco - Yes. We thought that far ahead. No a good scenario, for sure.

try Almit Sn62 HM1 RMA V14L ....its the best no clean lead paste for wetting...I sell it and it has solved wetting problems many times when users have used other pastes

I am a big fan of AIM SnPb solder paste. I currently use NC257-2 (no-clean, 89.5%), and recommend you include it in your evaluations.
