Packaged in a convenient 5cc syringe with plunger and tip, it ensures mess-free application and long shelf life when refrigerated, making it the go-to choice for professional-grade electronics assembly. ## Description Solder Paste no clean 63Sn/37Pb in 5cc syringe 15g w/plunger & tip.Metal Content: 88% metal by weight.Particle Size: T3 (25-45 microns)Size: 5cc/15g syringe Review: Pas pour les amateurs - La pâte est précise et fonctionne à merveille... ce n'est pas un produit pour débutant car si mal appliqué ou en trop grosse quantité, ça peut créé un court-circuit... pas assez, la soudure ne tiendra pas. Somme toute, excellent produit, je recommande. Review: The only solder paste I trust for production runs - 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. ## Features - Solder Paste - Leaded - No Clean - Syringe ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0186IM0P0 | | Country of Origin | USA | | Item Weight | 0.28 g | | Item model number | SMD291AX | | Manufacturer | Chip Quik® | | Package Dimensions | 10.16 x 5.84 x 2.03 cm; 0.28 g | ## Images ![Chip Quik SMD291AX Solder Paste no clean 63Sn/37Pb in 5cc syringe 15g - Image 1](https://m.media-amazon.com/images/I/51q8zfAFVaL.jpg) ![Chip Quik SMD291AX Solder Paste no clean 63Sn/37Pb in 5cc syringe 15g - Image 2](https://m.media-amazon.com/images/I/71lnqIh6a8L.jpg) ## Questions & Answers **Q: What is the ratio of lead? 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 ### ⭐⭐⭐⭐⭐ Pas pour les amateurs *by S***C on 12 May 2022* La pâte est précise et fonctionne à merveille... ce n'est pas un produit pour débutant car si mal appliqué ou en trop grosse quantité, ça peut créé un court-circuit... pas assez, la soudure ne tiendra pas.

Just be careful when using it- wear gloves, clean up afterwards and perhaps even wear a face mask to prevent breathing in the fumes. ## 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.)
