CS-Flux 5g Low Viscosity Halogen Free Liquid Flux for BGA Component Rework Reballing Reflow Ideal for VGA GPU Repairs and Microsoldering, CSGR

I used it once for fixing up a failing GPU when they started getting expensive a few years back (2020-ish). Did the whole thing just like in their training video where I spread it around the main chips and reheated them. Then after that worked, I kind of laid this flux aside for a while. Then recently, I was doing some rework and needed to make some delicate work on a PC board and add solder to pins, then remove it using braid. This flux was almost magical with how well it performed. I'd put a small bit on the pins first, then when I heated the solder and applied it, it would just flow right to the pins with almost no effort. Putting that daughter board in was easy using this as well. I laid a bit along the "joint" and then just kind of blobbed the solder in there and it flowed to the pins by itself.

Been using this exclusively for a few years now for BGA and SMD work in general, there is no comparison. If your doing a simple reflow then this will be your best chance at success. If doing a reball you will see its the perfect consistency, causes a nice flow, and is absolutely no clean and leaves the chip clean. Regular SMD work its great for small pitch pins.

Worked great for reflowing a PS3. It’s goes on thinner than other flux, so it flows nicely when heated. When it dries it leaves a dusty white residue behind but it’s easily cleaned with some IPA. It does have a really bad odor, so make sure you keep it sealed in a bag when you’re not using it and work in a well ventilated area.

Se trabaja muy bien

Makes rework much easier (or even possible!) compared to just heat and lift. Used for a BGA component on a laptop and worked like a charm flowing quickly and smoothly. Needle tip also screws on and off easily and securely.

Does what you need

Flux works great. Does what it's supposed to do

This flux made it so easy for me to replace solder and ic chips. I replaced a few chips on my sons Nintendo switch and I used this flux to set the joints. I would not have been able to without flux and this is very high quality

よく溶けて、溶けた状態でイモハンダになりにくく、光沢があるハンダが可能です。 ブロワーにてチップ部品やモスフェットをハンダする際に使用しています。

Suelda muy bien

Nikel, mon mari en est ravie pour les composants électroniques.

I use this product for electronic repair and kit building while producing YouTube content, its important that the items I use work well, this flux is very good no issues at all. I will happily order again with no reservations at all.. Good product, works well..

Works well dose the job for me.
