Chip Quik NC191LTA10 Smooth Flow Low Temp Solder Paste Sn42/Bi57/Ag1 T4 10g Syringe

First time using solder paste after 25+ years. Nice that it shipped with two nozzles. I did manual soldering. Needed to remember to release extra paste till see liquidish substance coming out. Spread the paste on pads, not too thick. Do not worry if it touches adjacent pads. Pressed ADXL345 LGA chip onto the pads. Used 150 deg C heat gun. The paste solder melted in a few seconds and chip just sat there. Very nice result. Never using solder for chips with funky pads. Good product.

This is an excellent way to remove electronic components from heat sensitive circuit boards. You can achieve solder melt at temperatures around 300 degrees F. Just apply over top of the leads on lead or lead free solder and using a hot air rework machine bring the area up to around 300 degrees F. The solder paste will blend with the solder on the board and allow you to remove the component without excessive heat. Always re-tin the pads the original solder and wick off to remove any residue of the bismuth from the removal.

Works great. Mush easier then traditional soldering. Works with a lighter or soldering iron. Magic stuff.

For an extremely gentle solder that absolute no tension will be involved…this is great. But it has broken its solder joints 8/10 times for me.

I have been working in some type of electronic industry (design, manufacturing, repair etc) for 30 years. Never would I have imagined that I would be able to repair a BGA IC at home without a reflow oven until now. This product saved me $415. Very pleased with this purchase.

I normally have good luck with this. But I didn't use it this time for 2 weeks, and then it was balling up pretty badly. It's still useful, but the balls remain after flow, which creates a mess that must be cleaned off before testing. (It's not easy to get the ones that end up under components.)

Absolutely the best low temp solder paste I have used. I haven't purchased a solder oven yet. It's on my wish list. Used my hot air gun. Super easy. I have been doing this for a long time time...decades. But, I wanted to see how easy it was. I made a mess with it, and it's super forgiving. And, if you do accidentally made a bridge, it's so easy to clean up and or desolder. My go to past from here on out!

Easy to use and it worked as it is supposed to.

This Solder Paste whilst may seem a bit expensive is a really good product and worth the money in my opinion. It's easy to use and makes working on small circuit boards a breeze, whether you are placing new components on a fresh PCB, reflowing, removing components or resoldering it is great. Working at lower temperatures means less chance of damaging the components, pads etc. It is definitely one of the best I've used so far it seems to go along way, has a good amount of flux in the mix and cleaning was easy afterwards.

I prefer this soldering paste because 1. Much easier to get out of the syringe, does not require heavy pushing as with MG Chemicals one 2. Melts instantly, and goes into place thanks to the decent amount and quality of flux 3. Lead-free

Easy to work with, low melting point. Comes with reflow profile.
