Electroplated nickel and electroplated gold is the more �traditional� finish for aluminum wire bonding. That surface was an extension of gold thermosonic wire bonding that requires a thick [50 thou min] gold surface. For years fabricators recommend

This sounds like you are using a straight ramp profile. For this type of an assembly you may need to use a soak type profile. Most solder paste providers show you both types of profiles that work best with that paste. I would try using that profil

Are you sure there is any "cleaning" needed? Can you see leftover bits of the teflon remaining? If so, work on it with an Xacto knife. But, most thermocouple wires are VERY hard to solder - as in practically impossible. Many of them have aluminum

If your using regular 63/37 Sn/Pb solder there are alot of other metals such as Antimony,Nickel,Iron,Cadmium,Aluminum,Copper,Gold,Bismuth,to name a few. But you need a certain amount of these metals for proper solder composition. Regarding the Antimo

I used to work for an OEM that made professional audio equipment (studio monitors, mixing boards, etc.). The mixers required precise alignment of LEDs, switches, and pots in the sheet metal so we used aluminum alignment fixtures during wave solder. T

Hi Myriam, I think we may need some more information. Is the Electrolytic (Aluminum) Capacitor placed more than once per board? If so, are all locations twisting? This would typically be caused by a thermal imbalance that could be design induced. (u

We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te

Well, the story is a little more complicated. The product is also an LED lamp made on an aluminum PCB with the LEDs on one side and the drivers on the other. The board itself is not big, about 90x90mm and most of the components are soldering well. Us

The aluminum material is typically plated by a zincation process, followed by nickel plate and a gold flash layer. What do the soldered side of the component and the soldered side of the aluminum coin look like? Do they both take solder?

Would you by chance be soldering copper to aluminum?
