Hi Greg, Depending on the rigidity of the adhesive and the type of components the adhesive touches, unbalanced staking can cause say ceramic components to crack/fracture. It is best practice to limit staking to the components specified and prevent overflow onto adjacent components. If you cannot prevent overflow onto adjacent components, then it is best practice to also properly stake that component as well. Hope this helps. Overflow onto adjacent components is generally not desired or a good thing and needs to be monitored and controlled closely. Best Regards, -Joe M.

I have a question I could directly answer so I thought I would put it out to the friendly experts of TechNet. After soldering and during the component staking process some adhesive has migrated onto adjacent solder connections and land areas. Could this become detrimental in a high vibration environment? I know from 610 and 001 that adhesive shall not contaminate the creation of the solder connection. However this is AFTER the soldering process is complete would this be a concern? Any thoughts?
