00:00Fix Cold Solder Joints With This Flux
00:03If you've ever reheated a joint that still looked like a little gray pebble, you know the pain.
00:08Cold solder joints are the number one reason a dead board stays dead.
00:12I dug through the best flux deals out there so you can fix that tonight,
00:15these are the ones actually worth your money for fix cold solder joints with this flux.
00:20Start with this one.
00:23The YFRMA223 comes in a 10 cubic centimeters needle tube,
00:26so you get syringe-level precision without syringe-level pricing RMA223 Rosin Blend,
00:32thin enough to sneak under a lifted pad without flooding the board.
00:35That's the sweet spot for phone PCB, BGA, and everyday SMD rework.
00:41377, nearly 5,000 sold, and a perfect 5-star average.
00:46This isn't an experiment, it's the cheap insurance every repair bench keeps on hand.
00:51Now the Mechanic XG50 costs more, but there's a reason, it's solder paste,
00:55not just flux, and it melts at 183 degrees Celsius.
01:00One swipe and you're laying down fresh metal on the joint instead of just cleaning the old one.
01:05If you're re-balling or doing fine SMD chip work on phone boards,
01:09this is the smoothest feeling option in the pack.
01:12791, almost 5,000 sold, rated 4.9.
01:16The Oak No Clean Flux is the sleeper pick.
01:20It's a 10 cubic centimeters soldering oil that flows into hairline cracks
01:23and tight gaps that thick paste just bridges over, which is exactly where cold joints hide.
01:28Because it's no clean, you skip the IPA scrub afterward and avoid disturbing pads you just fixed.
01:34For bucks for something that saves an entire teardown?
01:38That's a steal.
01:40The KEK Original 559 is the classic 559 every repair tech already knows.
01:46Needle tube, rosin-based, and it doubles as a desoldering agent,
01:50so it helps drag old solder off a pad as well as help new solder stick to it.
01:55If you're cleaning a pad before laying a fresh joint, this one pulls double duty.
02:00For 69, over 3.700 sold, and the ratings hold.
