Hi. Anyone in this forum experienced the lead-free solder paste SAC305 and SAC405? What are the differences to expect for solder paste with SAC305 and SAC405? What is the effect of silver (Ag) alloy in solder paste? It was really appreciated if could

The component should float into place provided you have the correct amount of solder paste. Perform a solderability test on the pads. We have come across new components with oxidation that prevents wetting. This will cause components to not self ali

Like I said a lot of people don't tape the gold fingers the first time they run them. After that they make sure the fingers get taped up because solder gets places you don't think it does and once it touches gold, that gold is contaminated. How do y

Here are the nozzles that soaked, but didn't get tinned. Since the solder joints also had yellow, I am wondering if the contamination is lingering in the solder pot, and getting on the joints. The Superior is never applied to a board. In the board

I'm sure this isn't the same situation, but we did have a selective solder machine with crazy dross and solder ball build up. Turns out the operator switched the low pressure nitrogen line used for solder level and the high pressure nitrogen line fo

Hi Researchmfg, If upload picture would be great to interpret this question, anyway,if bridge occur defect should be adjudge NG product,to avoide this issue,firstly,bridge is a PCB defect that happens when solder gets to an area it shouldn't be. You

I ask for advice on starting wave soldering machine. The soldering machine is not new. Are there guidelines for properly loading solder into a bath and more. I also ask you to recommend an alloy. What do you think about Alpha Sn Plus 07 or SN100C(Sn

Hi Was wondering what the general take is with reflow profiles to take into account differing solder paste alloy compared to the solder alloy used for the bumps of a bga device. For instance, SAC305 solder paste and BGA device with SAC105 (higher m

IBM, Endicott, New York did extensive research on that. There was also some information I think that was published. You may want to contact Howard Manko of Manko & Associates. He's the soldering guru and has written many books on soldering & solderab

Anybody have problen soldering a IC with leads that are copper base, plated with 300 u inch min. of 80Sn/20Pb solder? We are having problems soldering a 16 mil QVSOP to a Gold Flash Board. Thanks Chris
