Superior fluxing ability with Instant wetting Made in the USA This flux is free of any halides, resin, or rosin. This flux was designed for soldering high quality electronic printed circuit boards (PCBs), such as, throughhole, mixed technology, and surface mount assemblies while eliminating the need for a post cleaning operation. Residues are NonCorrosive and NonConductive. If removal of the residue is needed then it can be cleaned with warm water. Flux conforms to IPCANSIJSTD004, Type ORL0. This Product is RoHS Compliant ## Features - For rework and touch-up of SMT, SMD, and through hole solder joints - Contains 10 ml of No-Clean Low Solids Flux - Suitable for automotive, computer, telecom - Environmentally Friendly Refillable Pen - Compatible with Lead and Lead-Free Solders ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B008OC0E5M | | ASIN | B008OC0E5M | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #70,841 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #188 in Solder, Solder Fluxes & Pastes | | Customer Reviews | 4.6 4.6 out of 5 stars (1,015) | | Customer reviews | 4.6 4.6 out of 5 stars (1,015) | | Date First Available | 17 October 2013 | | Date First Available | 17 October 2013 | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 18 g | | Item model number | PEN-NC | | Item model number | PEN-NC | | Manufacturer | SRA | | Manufacturer | SRA | | Part number | PEN-NC | | Product Dimensions | 13.72 x 2.54 x 0.76 cm; 18 g | | Product Dimensions | 13.72 x 2.54 x 0.76 cm; 18 g | | Size | No-Clean Pen | ## Images ![#312 Flux Pen Low-Solids, No-Clean 10ml - Refillable - Image 1](https://m.media-amazon.com/images/I/41stXrl7a2L.jpg) ## Questions & Answers **Q: What is the difference between the different SRA numbers? For example this one says SRA# 312 and another is SRA #99-20 and there are even more.** A: Flux normally comes in three different strengths, light (no-clean), normal (RMA), and strong (Water Soluble). #312 appears to be the weakest one and probably best for light work on sensitive materials. #90-20 appears to be the medium strength and probably the best for general all around use. #80 "This is a high activity halide, Neutral organic acid (OA) flux formulated for difficult-to-solder surfaces where activated rosin fluxes and less active OA fluxes cannot be used." (and probably not needed except for extreme situations).References: http://sra-solder.com/sra-312-no-clean-flux-pen-refillable/http://sra-solder.com/sra-99-20-rma-rosin-flux-pen-refillable/http://sra-solder.com/sra-80-water-soluble-flux-pen-refillable/ **Q: What do you use to refill with, how, what brand, etc...? I want to try but want to know before I order and need more of something that I do not have.** A: This is the same pen with a bottle holding 5 refills included http://www.amazon.com/SRA-312-No-Clean-Flux-Refill/dp/B008Q1F92E **Q: Can this flux be used to solder 2 pieces of magnet wire together? If not, what flux do I have to use? Thank you a lot!** A: I'm honestly not to sure what you mean by two magnet wire? I'm imagining you mean joining two solid (magnetic) rods together? In this case I would imagine a 50/50 lead/tin solder however, I'm not sure what the magnetic rods consist of. You may want to consider a mig/tac. **Q: I make jewelry and I need to solder some pieces together. Will this work for it?** A: This is flux so you would need solder.
