Designed for precise application via a spring-loaded felt tip, it supports both leaded and lead-free soldering while ensuring non-corrosive, RoHS-compliant performance—ideal for professional prototyping and repair on PCBs and surface-mounted components. ## Description The 835-p rosin flux pen contains a Type RA rosin-activated flux composed of Pure water white (WW) grade gum rosin. It is a unique solvent system that contains very effective activators. The superior fluxing remains consistent throughout the entire aeration process. The 835 provides fast wetting action and complies with all requirements for Type Rom1 flux per j-std-004. Application: the 835-p pen is designed to dispense flux in a precise application and used for leaded and lead-free chemistries. Excellent for prototyping and rework/repair on printed circuit boards. Works well on chip carriers, heat sinks, surface mounted device pads, switches, and sockets. Application instructions: the flux pen controls the flow via a spring-loaded felt tip. This helps keep evaporation to a minimum between use. 1. Depress the tip against a hard surface until the felt tip gets wet, but not flooding. 2. Gently brush the wet tip onto the soldering area to apply. To keep the felt saturated and the flow controlled, only press in the tip as needed. Attention! do not continuously keep the tip Depressed or do not press too hard. This can jam the Valve open and cause flooding. Note that a fresh felt tip will take a several seconds to fully saturate, so expect a delay before the flux starts to flow on first use. Moving the tip in circular motion can help loosen the felt fibers and speed up the saturation process. Review: Was able to use on my last soldering project and it was awesome - This was one of my best experiences using flux at home. My other syringe of MG Chemicals flux worked well with soldering but was a slow messy process to get out of the syringe. With these pens it is SOO much easier. These are no clean but it still leaves a flux trace after soldering. This residue does dry firm so it is not a goopy mess like previous fluxes which is also a huge plus. Review: Solid Flux Pen - After reading several reviews here on desertcart, I was a little hesitant to purchase these pens. I did not experience any of the issues others have complained about while using them. When I first opened the pen, I was careful to only press down enough to prime the pen. The tip will turn yellow when it is saturated with the flux. Once the tip is primed you really do not need to pump it or press hard for the flux to flow. I used this to modify the motherboard inside an original xbox console and the solder points were very small. This pen put just enough flux to board to allow a good solder connection without drenching the board in flux. It worked exactly like it needed to. I would recommend this product to anyone, just use it as intended. ## Features - For leaded and lead-free solder - Fast wetting - Non-corrosive - Non-hygroscopic - RoHS compliant ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 792 Reviews | ## Images ![835-PX2 Flux Pen Soldering, 2 x 10 mL, Amber - Image 1](https://m.media-amazon.com/images/I/61Lzg-1HpuL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Was able to use on my last soldering project and it was awesome *by D***. on February 22, 2021* This was one of my best experiences using flux at home.

I used to use it all the time for assembling really small surface mount components and this product hit the nail on the head m as to what I was wanting for all applications! Doesn't gel up, cleans up great with isopropyl alcohol and a Q-tip or what not.
