And what is the suggested melt temperature?** A: The old days back in 1960's was 60/40 tin/lead rosin core called for electronics. You new solder is liquid is 63/37 tin/lead. I had to look this up my self. I hope this helps you. **Q: Where do i purchase smaller tips for this?** A: So an Amazon search on "Dispensing Needle 1 - Blunt Tip Luer Lock" https://smile.amazon.com/s?k=Dispensing+Needle+1+-+Blunt+Tip+Luer+Lock&crid=Z897DQLHIWFP&sprefix=dispensing+needle+1+-+blunt+tip+luer+lock%2Caps%2C113&ref=nb_sb_noss_2 **Q: Is this used like typical coiled electronics solder, but with more control of where it goes? Just touch with iron to heat?** A: Yes and no. This is really made for soldering surface mount soldering with either a heat gun or a soldering iron. I wouldn’t recommend it for through hole soldering. However its great for surface mount. **Q: What is the inner diameter of the dispensing tip?** A: I don't know the tips exact size, but it is very small and only dispenses a very small amount of material when used. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The only solder paste I trust for production runs *by on Reviewed in the United States June 7, 2026* Not going to pretend this is a discovery — Chip Quik SMD291AX has a reputation in the hobby electronics community for a reason and that reputation is earned. Been running this through a stencil on leaded paste reflow work for a limited board run and the results have been consistently clean across the whole batch.Paste consistency is exactly where it needs to be. Extrudes smoothly through a stencil without bridging on fine pitch pads, holds its shape between application and reflow without slumping, and the tack is strong enough that components stay put through handling without shifting before heat is applied. These sound like baseline requirements but cheaper pastes fail at least one of them reliably.63/37 eutectic alloy means a sharp liquidus transition at 183°C with no plastic phase — you get a clean reflow without having to babysit the thermal profile as carefully as you do with non-eutectic alloys. The joints come out shiny and well formed consistently.No clean flux residue lives up to its name. Left the boards as-is after reflow and the residue is minimal, non-corrosive, and doesn't cause any issues with continuity or appearance. When I do clean it IPA takes it off without any effort.5cc syringe format is practical for stencil work and hand application on rework. Keep it refrigerated between sessions and it stays workable for a long time without drying out or separating.If you're doing any volume of SMD assembly and still experimenting with paste brands stop experimenting. This is the one. ### ⭐⭐⭐⭐⭐ The best solder paste if stored in the fridge. *by on Reviewed in the United States October 30, 2025* I've been able to use the same syringe of this flux for years, storing it in the refrigerator. I've had better results with this flux than others when stenciling. The solder seems to reflow more easily and the components stay put when using a hot air iron at low air velocity. Throw it in the refrigerator for a bit, or it will tend to stencil into small puddles instead of well-formed shapes. In my opinion, it's the best. ### ⭐⭐⭐⭐⭐ Worked Well *by on Reviewed in the United States January 17, 2025* I accidentally bumped the batter connector off of an iPod Classic, and could not get the pads properly soldered with a normal spool of solder and looked into alternatives. It has been well over a decade that I had to solder some SMDs, so I forgot about liquid solder/solder paste and after seeing a couple Youtube videos using it I figured it is much cheaper than replacing the logic board, so if it doesn't work, no big deal.I was able to clean off the pads and put a drop of paste on all three pads and easily solder it back down with a wide tip. Since I didn't have good precision tweezers, I had a small bridge between two pins, which I was able to eventually get cleaned up. By no means meant as a problem with the paste, but just be careful not to use too much. :) ## Frequently Bought Together - Chip Quik SMD291AX Solder Paste no clean 63Sn/37Pb in 5cc syringe 15g - YIHUA 959D-Digital Hot Air Rework Station, High Power with 3 Memories, Airflow Efficiency, °F /°C Display, Accurate Temp.(212°F~932°F), Brushed Aluminum Panel & Safety Features - Liquid Solder Flux Dropper (30 ml/1 Oz.)
