Hi, anyone know how the oxidation of SAC Solder Ball behave? How does the amount of Ag and Cu content affect the formation of oxide layer? Thank you

Questions are: * How did you determine that the coating on your component leads is oxidation? * What is the oxide? BR, davef

Are there standards that dictate how long a EEE component can be exposed outside of a nitrogen bag before oxidation occurs? Since Covid I am seeing more and more caps and resistors that seem to have oxidation and do not solder well....

Sirs, Please do me a favor to answer the following questions, thanks a million! 1. Will the baking of BGA or PCB cause more oxidation before the SMT process? 2. What is the acceptable Life Time of solderability at customer site? The time that the sol

Plating houses seem to exhibit various results. Unacceptable Ni oxidation levels appear to be related to poor Pd plating processes. Ni oxidation can occur at 3 process stages: 1) prior to the Pd being applied (Ni already oxidized) 2) during the p

Have QFP at o.5mm pitch with leads too oxidized for the flux in the paste to de-oxidize(in stock for boo koo time). I saw three companies on the Internet that can "tin" (solder coat) the leads. Does anybody have any experience with having this done t

�..... their material acts as a barrier to oxidation," is wrong Mr. N. The MS2 material "consumes" oxides therefore removing the oxides from the dross by chemical reaction and releases the pure alloy. It is not a barrier and does not mix into the sol

SMT fine pitch connector having oxidation on lead and P&P machine keep rejecting the part. Is there any alternative way to reduce the part throw out rate without jeopardize the placement accuracy? Or is it possible to re-coat the connector lead or an

Kleenox is designed for cleaning and protecting the solder bath in wave solder pots from air oxidation and formation. Kleenox is formulated to remove oxides. Kleenox can be used with tin/lead and lead-free solder. http://www.americancleanstat.com/k

Lead free HASL coatings can be susceptible to yellowing during reflow due to oxidation of the tin in the coating. Some HASL solder suppliers use anti-oxidant additives in the solder to limit or prevent yellowing of the coating. You may want to ask
