    Signs You Need A Better Flux

    Bad solder flow nearly always points to weak or dried flux.

    Cold Or Dull Joints

    Solder will not melt smooth. Joints look grey and grainy.

    Solder Will Not Wet

    Solder beads up and rolls off the pad.

    Bridging Between Pads

    Solder jumps across fine-pitch pads and shorts.

    Oxidised Pads

    Old boards resist tinning without fresh flux.

    Old Flux Dried Out

    Your current jar has gone stiff and crusty.

    BGA Balls Will Not Seat

    Reflow stays uneven and chips sit crooked.

    Why Halogen-Free Who Uses It Right Flux? How To Use Pair With Specs Works On FAQs

    Why Halogen-Free Matters On A Phone Motherboard

    Halide-activated fluxes wick fast but can leave conductive residue.

    Low Corrosive Residue

    The activator system is halogen-free. Very little corrosive residue is left behind.

    High Surface Resistance

    Low ionic residue means low leakage between pads. This protects fine charging IC lines.

    Low-Odour Bench Use

    Low smoke and low odour during use. Still work in a well-ventilated space.

    No-Clean Workflow

    Skip the IPA cleanup step on most jobs. Handy near speakers and Face ID flex.

    BGA Wettability

    The high-tack gel spreads evenly across BGA pads. Solder balls form predictably during reflow.

    RoHS Compliant

    Lead-free and halogen-free per Qianli spec. Suits RoHS contract builds and refurb resale.

    Confirm Flux Is What You Need

    Run this quick check before you buy. It saves a wrong order.

    • Need better solder flow and wetting? Flux is the right product.
    • Joints look dull or cold? Fresh flux fixes wetting.
    • Need tin spheres added too? That is solder paste, not flux.
    • Removing old solder? Use desoldering wick or a pump.
    • Reballing a BGA chip? You also need solder balls and a stencil.
    • Fixing heavy 30-year oxidation? An aggressive leaded RMA may wet faster.
    • Working near speakers or Face ID? No-clean flux is ideal.
    • Building to RoHS export spec? Lead-free and halogen-free suits the job.

    How To Use — Safe Bench Workflow

    Follow this order. Skipping a step is the top cause of a bad flux job.

    Step 1 — Stir Before Use

    Activators can settle on the shelf. Stir the jar before each session.

    Step 2 — Clean The Pads

    Wipe the joint with IPA and a lint-free swab. No-clean flux cannot fix dirt.

    Step 3 — Apply A Small Dab

    A pinhead dot suits one SMD pad. Too much causes bridging.

    Step 4 — Set Your Heat

    Iron 320-360°C for leaded. Use 360-400°C for lead-free.

    Step 5 — Reflow The Joint

    Apply heat and watch the flux activate. It works as the solder melts.

    Step 6 — Optional Final Wipe

    For refurb resale a quick IPA wipe lifts any film. It is not required for function.

    Store it right: keep the jar sealed at room temperature, away from direct sunlight.

    Pair This Flux With These Tools

    Soldering Iron

    A temperature-controlled iron with a fine tip.

    Hot Air Rework Station

    For BGA reflow and IC removal jobs.

    Solder Wire

    SAC305 lead-free or Sn63/Pb37 leaded.

    IPA And Lint-Free Swabs

    For prep and the optional final wipe.

    Precision Tweezers

    For placing 0402 and 0603 components.

    Dispenser Needle Or Spatula

    For neat, controlled flux placement.

    iPhone Boards Samsung Boards iPad MacBook Logic Boards PS5 Xbox Nintendo Switch Drone/FPV Boards TV/Monitor Boards Hobby PCBs

    Not A Substitute For

    • Solder paste — that contains tin spheres, this is flux only.
    • Solder wire — you still need wire to add solder.
    • Desoldering wick or pump — flux assists wicking, it does not remove solder.
    • BGA reballing alone — that needs solder balls and a stencil too.
    • Aggressive leaded RMA — heavy old oxidation may wet faster with that.

    Qianli Halogen-Free vs Traditional Rosin Flux

    Qianli Halogen-Free No-Clean

    • Low non-corrosive residue, no mandatory IPA flush.
    • No chloride or bromide ions to attack pads.
    • Low smoke and low odour at the bench.
    • Lead-free and halogen-free, suits RoHS builds.
    • Even spread across BGA pads under hot air.
    • Best for modern phone, tablet and console boards.

    Traditional Rosin Flux

    • Conductive ionic residue stays on the board.
    • Halide residue can cause corrosion if uncleaned.
    • Strong rosin smoke needs fume extraction.
    • Often contains lead and halide activators.
    • Can slump and spread unevenly under hot air.
    • Best for heavy through-hole and vintage work.

    Repair Expert FAQs

    What does halogen-free actually mean?+
    It means the flux has no chloride and no bromide activators. Halide salts can leave corrosive residue. This formula uses a halogen-free activator system. Very little corrosive residue is left behind.
    Do I really not need to clean the board after?+
    For function, no cleaning is needed. The residue is low and non-corrosive. For cosmetics, many techs still wipe with IPA. That step is optional on refurb resale jobs.
    Is it the same as solder paste?+
    No. Solder paste is flux mixed with tiny solder spheres. This Qianli product is flux only. Pair it with separate solder wire when you need solder.
    What temperature should my iron be set to?+
    Set the iron to 320-360°C for leaded solder. Use 360-400°C for lead-free SAC305. Hot air runs 320-380°C. Keep airflow low near tiny parts.
    Is 50g enough for a busy repair shop?+
    Yes, 50g is the pro-pack size. It covers hundreds of jobs at a pinhead per pad. A busy bench often uses one jar in a few weeks.
    Is it safe for BGA reflow on iPhone or Samsung boards?+
    Yes. BGA reflow is a primary use case. The high-tack gel spreads evenly across BGA pads. Solder balls form predictably during reflow.
    Will it work for PS5 HDMI port repair?+
    Yes. PS5 HDMI port reflow is a common use. So is Xbox APU work and Switch joycon rework. The no-clean residue saves a flush after each job.
    How long does an opened jar last?+
    Keep the jar sealed at room temperature. Store it away from direct sunlight. An opened jar holds activity for many months. Stir before each session to refresh it.
    How do I know it is genuine Qianli?+
    Qianli is a heavily cloned brand. We supply genuine product in sealed factory packaging. Every jar is bench inspected before dispatch. Check the seal when it arrives.
    What warranty applies to flux?+
    Flux is a consumable, so a 7-day DOA replacement applies. Inspect the seal when it arrives. A longer warranty does not apply to a consumable.
