Frequently asked questions
Is it genuine Amtech RMA-223?
RMA-223 is a model name that several sellers use. Genuine Amtech tubes are usually sold by authorized dealers; cheap listings are often generic copies, so treat the quality as unverified.
Do I need to clean the board afterward?
No-clean flux is designed to be left, but residue can attract dust or look messy. Wipe it with isopropyl alcohol for a neat finish.
How should I store it?
Keep the syringe capped and stored in a cool, dry place away from heat and sunlight. Flux paste dries out and separates when it gets warm, so a drawer or a sealed container works well.

Usually one to three weeks, sooner for Choice and US-warehouse items. Tracking is provided, and Buyer Protection covers non-delivery. Import fees may be added at checkout.
