Hi. Is there anyone with experience in soldering standard smd on a pvd (physical vapor deposited) titanium surface? Are there any rules to obey? Especially concering solder paste, surface treatment, reflow profile and oven etc. Thanks

The most likely cause is moisture vapor outgassing violently from the Tant package. They are known to be moisture sensitive. Try baking some at 120C overnight and reflowing those.

could you elaborate on the type of component involved to help us understand the issue better....if this assembly is a special case you might try vapor phase soldering of that assembly...although that is a capital investment if you are not currently s

When we hear the words 'flexible circuit' and 'delamination' in the same sentence, we think: * Excessive reflow temperature. * Entrapped moisture. Boardhouse: I hope this is a step towards redemption.

We have been doing pilot runs with vacuum installed on vapor phase. Voids are down but bridges are up on the .5mil BGAs.

We are using a Propyl Bromide vapor degreaser solvent. Has anyone heard of this solvent when used near an oven will decompose and cause major corrosion to metals such as in a Reflow oven or a wave solder pot?

Thanks for all the input. Going to try vapor phase. We have an Asscon Q300 demo. I'll post results when we have them. Jim

We using nitrogen only for Selective Solder machine, you don't need it for reflow oven, to improve solderability we use Vapor Fase oven.

I looked at the tech data for the coating. It appears to need an explosion proof oven for curing (flammable vapors from solvent). I doubt the Heller reflow is explosion proof type oven.

If its low volume maybe vapor phase desktop unit? I heard they work like magic and don't require any profiling. Rehm is supposed to be the best brand especially in europe. Overbuilt and even better than Heller but not too popular in US.
