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 mean...there are a ton of possibilities for bridging on selective solder before you ever get to alloy purity. Are the bridges happening consistently in the same spot? Are the leads too long? Can you modify the approach/exit/peel off to address? Wh

Process Flux is AIM 275. Tip tinning flux is Superior 75. We have gotten dual nozzles in the 6mm & 9mm sizes we run. We can get a nozzle to run about 8 hours. Every night we clean all used nozzles with a scouring pad, apply Superior 75 flux with

Chunks, We have custom nozzles here in Riyadh that are designed to solder through-hole with SMT 0805 R's and C's just 0.5mm away. ERSA charged an arm and a leg for these, so I buy them from my toolmaker, Asadulah , for half the price. They come in

If you're using a good quality nozzle, you can clean the oxidation off with a wire brush and an emery cloth. Just make sure you re-tin it very well before you use it.

Yep, done it previously with a multipot machine. Using with wirefeed to top up the pots means you only have a contamintion risk when you fit a new top up reel. Used separate nozzles for both, but theoretically using titanium nozzles would mean no c

We did not try using water. Once the nozzles were left in the pot a while longer, the yellow goes away. Suggesting that it's cooking off.

Hi Tom, I did talk to Bob Gilbert about the sn100c. His comment is that it is a nickle stabalized alloy. Simplisticly, the tin and copper molecules would rather bond with the nickle. He also mentioned that with the SAC alloys, the manufactuers were

Due to spacing issue, we are considering using power bricks with tin/lead solder ball instead of PTH package. The solder ball is 40 mil diameter. Our CM suggested they do hand place since the pick and place nozzle cannot pick up and hold the part due

Good question, the answer as of right now is yes. Our machine is only able to go down to 0402 parts before the surface tension of the solder begins to cause issues with maintaining the placement position of the part on the nozzle. However, we are dev
