Qianli No-Clean Lead-Free Halogen-Free Solder Flux Paste 50g
This is a genuine Qianli no-clean solder flux paste. The net weight is 50 grams. It is lead-free and RoHS compliant. The formula is halogen-free per vendor spec. It contains no chloride and no bromide. The residue is low and non-corrosive after reflow. It is built for BGA reflow and IC rework. It suits iron and hot air soldering. It works with lead-free SAC305 and leaded Sn63/Pb37. The odour is low during long bench sessions. It is a high-tack gel that holds BGA balls. Use it on phone, tablet and console boards. Genuine Qianli pack, bench inspected before dispatch. Dispatched from Forest Lake, Brisbane QLD.
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.

Authenticity Guaranteed
Genuine Qianli 50g pack in sealed factory packaging. Lead-free and halogen-free per vendor spec. Qianli is heavily cloned, so we supply verified product only.
Reliable Dispatch
Standard 2-4 business day dispatch in protective packaging. Tracked delivery Australia-wide on every order.
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.

Works On These Boards
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.
