Chip QuikNC191SNL50 Smooth Flow Lead-Free Solder Paste SAC305 T4 50g Jar

I've been reflowing SMD boards since about 2005. I was looking for a backup source for paste. With this lead-free formula, I should be able to run the profile that hits 250'C and have it flow neatly and smoothly. on my boards. I found some areas that the solder had not flowed, and so I ran it through a second time. It still didn't flow. Then I tried touchup with my iron at 370'C. It didn't look good. I reached for the hot air pencil set at 400'C, and still didn't get good results. Perhaps I had not stirred the paste long enough before stenciling, but it looked pretty good right out of the tub when I started. I may try again, I'd like to know what I did wrong...

This paste worked as described. It's perfect for those quick hit solder jobs. A little paste, a couple passes with a torch lighter and just like the full on soldering iron job you'd do. It is a little pricey, but I'm willing to pay for stuff that works. The only downfall is I wish I had found this sooner. Once I run out, I'll definitely buy again.

This solder paste works well for me, and it produces good results when reflowing fine-pitch QFP parts. I recommend getting the jars (like this one) instead of the syringes because you can save any leftover paste by putting it back in the jar. The paste I received was fresh and had an expiration date 1 year in the future. I recommend refrigerating the solder paste when not using it to prolong its lifespan.
