The best idea with materials at hand... no "fludor sawdust" in the open air, no other chemical complications... I have a 30 gram box of Mechanic that has hardened since 2 years ago... I have a little flow( under technical warranty) RMA 223 (not Chinese)...I'll try to make the mixture from this video...I don't have that bga sieve, so I'm waiting to buy a set with small 0.03mm nozzles to make my paste again 218 Machanic...thanks for the help and detailed explanations and a year 2023 with health and happiness...my respect for your work
I use no clean liquid flux instead of gel flux to revive dried solder paste. Works great and all lumps also liquifies easily no need mesh to filter it just add right amount of liquid ( I use MULTICORE X32-15I NO CLEAN FLUX) and mix with flat bar till is perfect in 10 seconds
Did my solder paste liquefaction at today. Turned out that RMA-218 also dried too much. Added a gulp of Topnik TK83 liquid flux into mix to solve that. At last got rid of old RMA-218 jar. At end mixed all leftovers of Sn67Pb37 and ROHS solder pastes together with TK83 flux into one syringe. Will see what will come out of it. Smell nice, but IMHO fumes will be deadly without proper ventilation. FYI, next mortar mixers. Flux doesn't magically disappear when mixed into solder paste. It simply add to volume because physics. Original syringe almost certainly will become to small. Keep at least one or two hermetically closeable (plug, cover) empty syringes nearby. To deal with air bubbles in syringe, close it with a plug, turn with nozzle up and warm a little with heat gun on lowest temperature setting or hair dryer. Paste will liquefy enough to slide down into solid piece, leaving air at top and easy to remove.
I did a very simular thing excet all I had around was an old bottle of MG Chemicals Rosen Flux liquid. I just kept adding the liquid until it was smooth and lump free. the Only thing that you need to be aware of is the splatter from all the flux that's in the paste now. You want to be really carefull with the iron / Hot plate temps. Other than that it seemed to work. This was with 5 year old solder in a syringe RL-403
Can I ask if even if it hadn't not much to do with video if flat heat pipes for laptops can be bent without heating. I'm researching to find out more about this project where I want to mod a laptop heatsink with more heat pipes. For that I would have to shape the additional pipes I'll buy. Its just hard to find info about this that's why I'm asking here.
what is most interesting, you Westerners do not have critical thinking, believe me, on the street when you inhale car exhaust fumes, you get a dose of lead a hundred times more than when soldering

Hi friend thanks for the informative video

good tip thank you
👍👍👍👍👍💯
What is the name of reducer
It’s just rma-216 flux paste
@@MaxELECTRONICS RMA-218
was this lead paste? what was the temp on the gun?
I’ve done this for both leaded and lead free, temp is 300c
@@MaxELECTRONICS awesome. Thx.
KINGBO RMA-218 SOLDERING FLUX (OR SIMILAR)
Yes

You’d need pipe bender tool so you don’t crush them while bending
Filling pipe with sand helps to reduce/avoid waisting while bend. Sand should be compacted.
doesn't concern lead cross contamination? Im scared with that issue in leaded solder paste (its a bunch of microscopic balls).

No worries as long as you remember to wash your hands after job. And before touching food, dishes or your mouth.
Hi there, What is rma to 18? thanks
I’m not sure what do you mean ?
@@MaxELECTRONICS I mean the product you used
See the subtitle
Oh it’s what the flux called, so it’s a soldering flux with number RMA218, If you go on eBay you can find it there.
@@MaxELECTRONICS thankx
