Highlights
- Tacky paste flux
- MECHANIC brand
- Nano formula per the title
- PCB, IC, BGA work
Best for
A repair tech or hobbyist who needs flux and prefers a recognizable brand.
Things to consider
- This is the same product as another listing at a lower price, with slightly lower feedback, so compare.
- Tip: clean flux residue off boards with isopropyl alcohol after soldering, since leftover flux can corrode over time.
- Typical US delivery is roughly one to three weeks, sometimes a little longer in busy sale periods. If speed matters, filter the listing for Choice or local-warehouse shipping. Duties can show up either inside the price or as a separate line, so check the total.

Buying from AliExpress
AliExpress is a legitimate marketplace that is worth using for cheap, low-risk things like cables, tools, cleaning supplies and small home items, as long as you can wait and you buy from well-rated sellers. Skip it for anything safety-critical, brand-name or urgent. Check the seller's feedback score, the delivery estimate and the import-charge line at checkout before you pay.
- Shipping
- AliExpress's 2024 US guarantee listed Choice orders at 5 to 12 days and standard orders at 8 to 14 days, but real-world standard shipping from China often runs longer. Items marked Ship from United States come from local stock. Free shipping on Choice orders depends on a minimum order shown at checkout.
- Returns
- Eligible items can be returned within 90 days of payment, with the first return on each order free, according to AliExpress's 2024 US announcement. Return terms vary by seller and item, so check the product page. Custom, perishable and hygiene items are generally excluded.
- Warranty
- AliExpress does not publish a marketplace-wide product warranty. Coverage depends on the individual seller, and Buyer Protection covers non-delivery, damage and not-as-described claims instead.
- Payment
- US shoppers can pay by Visa, Mastercard, American Express or Discover, PayPal, Apple Pay and Google Pay. Instalment options such as Klarna and PayPal Pay Later appear on some orders, and availability varies.
- International
- AliExpress sells to shoppers worldwide. For US orders, import duties on low-value parcels have applied since the duty-free exemption ended in 2025, and state sales tax is added at checkout.
