Genuine Amtech Flux vs Fake AliExpress Flux – Test & Comparison

In this video, I compare genuine Amtech flux purchased from Amazon with a fake Amtech NC-559 flux ordered from AliExpress. You'll see a side-by-side test of performance, consistency, smell, label differences, and behavior during soldering. What’s tested: Real NC-559-ASM-TF flux, Suspected fake NC-559 from China, Amtech 4300 and LF-4300-TF samples. Fake flux can cause PCB damage, corrosion, and unreliable solder joints — watch before you buy!
