It seems like some oxidation that flux is able to fix on the soldered pads. Is it looking like this before you reflow?

No, you're correct. Nickel oxidation can be difficult to remove

Could the plating be oxidized, and repelling the solder instead of adhering?

Alcohol? Crud-cutter? Cant recommend much without knowing plating(if any).

Hi Sorry my poor english We have some problems with some componentes 0402 we recived by the manucterer oxide in the tape reells exactly in the bottom side to the reel I think the root cause is the oxide in the tapes rells What do you think? And ot

1. Check printing accuracy. 2. Check placement accuracy. 3. Your components should be kept in a good environment to prevent oxidation of terminations. 4. Pads pattern should be designed according to standards. If 1.2. are okay, you should suspect 3

Yes,thermal conductivity does decrease since all metal oxides are insulators to varying degrees,and this should be considered in trermal analyses.It is best to protect the copper against oxidation,however.Again,I suggest you include this question in

Let me see if I got this right. The OSP in un-plugged vias will break down after subsequent reflows and washes which can result in oxidation. Question: Is there any paper covering oxidation and reliability on such a condition. We are averaging .0007

Hello davide, the biggest advantage you'll find with a complete N2 tunnel is the minimization of oxidation during board preheating. Using only an inerted solder pot allows the oxidation to build up throughout the preheat stages and introduces contami

We are trying to solder a Surface mount relay having lead free finish on the leads. The leads are not getting soldered down during the reflow. The leads also look oxidized (failed our solderability test) but we don't have an option but to use these r
