    Why Halogen-Free Matters On A Phone Motherboard

    Traditional rosin fluxes use chloride and bromide activators. They wick well but leave conductive ionic residue.

    Synthetic Activator

    Dicarboxylic acid plus amine salt activators break down completely at solder temperature. Nothing corrosive remains.

    High Surface Resistance

    No ionic residue means no leakage current between adjacent pads. Critical on Audio IC and Tristar charging IC lines.

    Odorless Bench Use

    Comfortable for long bench sessions in a well-ventilated workspace. Suits repair labs and classroom benches.

    No-Clean Workflow

    Skip the IPA cleanup step on most jobs. Critical near speakers, microphones and Face ID flex modules.

    BGA Wettability

    Even spread across BGA pad arrays. Predictable solder ball formation during reflow at 220-245°C.

    RoHS Compliant

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

    How To Use — 6-Step Bench Workflow

    Follow this sequence. Skipping a step is the top reason a flux job goes wrong.

    STEP 1 — Stir Before Use

    Synthetic activators can settle on the shelf. Stir the jar for 10 seconds before each session.

    STEP 2 — Clean The Pads First

    Wipe the joint area with IPA and lint-free swab. Even no-clean flux cannot fix a contaminated pad.

    STEP 3 — Apply A Small Dab

    A pinhead-sized dot suits one SMD pad or 0603 component. Less is more, too much causes bridging.

    STEP 4 — Set Iron Or Hot Air

    Iron tip 320-360°C for leaded, 360-400°C for lead-free. Hot-air gun 320-380°C for SMD reflow.

    STEP 5 — Reflow The Joint

    Apply heat. Watch the flux bubble briefly then settle. The activator breaks down as solder melts.

    STEP 6 — Optional Final Wipe

    Truly no-clean. For refurb resale a quick IPA wipe lifts any cosmetic film. Not required for function.

    Pro tip: Store the jar tightly sealed at room temperature, away from direct sunlight.

    Common Mistakes And What This Flux Is NOT

    Too much paste

    A pinhead is enough per pad. Excess flux causes solder balling and bridging.

    Iron too cold

    Below 300°C the activators do not fully break down. Bubbling residue stays on the board.

    NOT a substitute for solder paste

    Solder paste contains tin spheres. This is flux only, pair with separate solder wire or paste.

    NOT for solder removal

    Use desoldering wick or a solder pump. Flux assists wicking, not removes solder by itself.

    Less aggressive than RMA leaded

    For 30-year-old heavily oxidised joints, an aggressive leaded RMA paste may wet faster.

    NOT for BGA reballing alone

    Reballing needs solder spheres and a stencil. The flux assists the reflow only.

    Qianli Halogen-Free vs Traditional Rosin Flux

    Side-by-side comparison of the synthetic-activator formulation against generic chloride-activated rosin paste.

    Post-Solder Residue
    Qianli Halogen-Free

    Activators break down at solder temperature. No corrosive residue and no IPA cleanup.

    Traditional Rosin

    Conductive ionic residue stays on the board. Mandatory IPA brush flush after every job.

    Long-Term Corrosion Risk
    Qianli Halogen-Free

    No chloride or bromide ions. No galvanic corrosion or whisker growth on adjacent pads.

    Traditional Rosin

    Halide residue plus battery rail equals dendritic shorts within weeks if uncleaned.

    Bench Odour
    Qianli Halogen-Free

    Odorless. Comfortable for long bench sessions in any workspace.

    Traditional Rosin

    Strong rosin smoke. Needs industrial fume extraction for prolonged use.

    RoHS Export Compliance
    Qianli Halogen-Free

    Lead-free plus halogen-free per spec. Meets RoHS contract assembly requirements.

    Traditional Rosin

    Often contains lead and halide activators. Fails most RoHS export builds.

    BGA Wettability
    Qianli Halogen-Free

    Even spread across BGA pad arrays. Predictable solder ball formation under hot air.

    Traditional Rosin

    Often slumps under prolonged hot air. Uneven coverage and cosmetic mess.

    Best For
    Qianli Halogen-Free

    Modern phone, tablet and console board work, refurb resale and RoHS contracts.

    Traditional Rosin

    Heavy through-hole work, vintage chassis, or jobs where cleanup is the workflow.

    Repair Expert FAQ

    What does halogen-free actually mean?+
    It means the flux contains no chloride and no bromide activator chemistry. Traditional rosin fluxes use halide salts to break down oxide. Halogen-free flux uses synthetic activators that break down at solder temperature. No corrosive residue is left behind.
    Do I really not need to clean the board after?+
    For function, no, you do not need to clean. The synthetic activators break down to non-corrosive byproducts. For cosmetics, many techs still wipe with IPA on refurb resale jobs. Cleanup is optional, not mandatory.
    Is it the same as solder paste?+
    No. Solder paste is flux plus tiny solder spheres mixed together. This Qianli product is flux only. Pair it with separate solder wire when you need solder.
    What temperature should my iron or hot air be set to?+
    Iron: 320-360°C for leaded solder, 360-400°C for lead-free SAC305. Hot air: 320-380°C with airflow controlled to protect 0402 components. Below 300°C the activator chemistry does not fully break down.
    Is 50g enough for a busy repair shop?+
    50 g is the pro-pack size. Enough for hundreds of jobs at a pinhead-per-pad usage rate. A busy phone bench typically goes through one 50 g jar in 4-8 weeks.
    Is it safe for BGA chip reflow on iPhone or Samsung boards?+
    Yes. BGA reflow is a primary use case. The synthetic activator gives even spread across BGA pad arrays and predictable solder ball formation at 220-245°C reflow.
    Will it work on console repair like PS5 HDMI port?+
    Yes. PS5 HDMI port reflow, Xbox APU corner-reflow, and Switch joycon connector rework are all common uses. The no-clean residue saves a flush after every job.
    How long does an opened jar last?+
    Stored sealed at room temperature away from sunlight, an opened jar holds its activity for over a year. Stir before each session to redistribute settled activators.
    How fast do you ship in Australia?+
    All orders ship from Brisbane in 2-4 business days. Brisbane metro 1-3 days, Sydney and Melbourne 3-5 days, regional and remote 5-7 days.
    What warranty do you offer?+
    A 7-day DOA replacement on faulty or unopened stock from delivery date. Inspect the seal on arrival. As a consumable, no longer-term warranty applies.
