Square ChipQuik No-Clean Rework Paste Flux - 5cc Syringe for PCB Repair & Solder Rework | High-Quality Plastic Non-Sterile Flux | Best for Electronics Repair, DIY Projects & Circuit Board Maintenance

I've been using this product for years, so the packaging kind of threw me. In the past it's looked exactly like the seller's photo. But now it comes with far more pieces, almost like a fun little puzzle.Chip Quik is probably better known for the low-temperature chip removal solder they make, not the flux that comes with it. But their flux is very highly regarded for its quality, and works great with lead or lead-free alloys. It is a no-clean type, so you can leave it on or wash it off.Previously, it was packaged with a rubber plunger, which over time will dissolve and contaminate the flux in the syringe, so if you don't use it up rapidly, you'll end up throwing some of the flux away. The product I received has been improved; the flux is contained in the syringe by a plastic plunger, and the syringe is ready to mount to pneumatic applicators. For hand-dispensing, the plunger and rubber cap are included separately, with assembly instructions. Even with hand-dispensing, the rubber never touches the flux, so I'm sure that the shelf life of the product is improved.In addition, you get a plastic nozzle and a metal one, which seems like a nice add-on, but I can't think of a reason why. It may help you to avoid scratching the PC board while working with the dispenser; but if you don't have a plastic soldering iron as well you're still going to have to be careful not to scratch things anyway.The syringe itself is physically smaller than the one I'm used to seeing, but contains the same quantity of flux.
