Cleaning

  • Isopropyl alcohol is commonly used for the task, and is inexpensive. You can also increase it's cleaning capacity by adding small amounts of either xylene or acetone if necessary (always test in a small, inconspicuous spot to see if it's going to remove the solder mask or legend).
  • You can also substitute ethanol, methanol, or denatured alcohol for isopropyl alcohol (may also be called IPA or isopropanol).

Should have gone with this store... :( - Or was it fucking fake???

  • Element14 Don't have the correct Multicore :(. They do have some 60/40. They also don't specify the flux type, although they have the id numbers sometimes.. Apparently Multicore 511 doesn't need cleaning.
  • Element14 *Don't have any 63/37 for 250g* :(

  • Some guys are on a forum are recommending .015 (or ~0.025, 0.28 - 0.71mm).
  • Carlsons Lab recommends .032 for through hole (some SMD, 0603,0805, 1206, middle of the road. At 0402 just use iron tip with external flux (so size doesn't matter?), 0.020 as being good for SMD and ok for through hole
  • Type R rosin, no activators needs a clean surface. RMA middle, most are no clean. RA (maybe as liquid flux).
  • Core size/flux amount in solder wire = 3.3% (sometimes called 66 core or P3)
  • EEVBlog MG Chemicals makes good flux and solder IME (on equal footing with Kester, Multicore, AIM, and so on). They don't offer as many variations as other manufacturers though. Even Multicore has cut back on their lead alloy offerings... AIM (American Iron & Metals) or Alpha (Cookson) make some excellent quality products as well, and at least here in the US, tend to be a tad less expensive vs. Kester.
  • EEVBlog MG options include RA and no clean flux, stating that cleaning is optional for the RA
  • 0.032"/.81mm is a little bit on the thick side

DIY/homemade Rosin flux with Isopropyl alcohol/glycerine/rosin? - flakes off a resin block / fluxoff comparison

That said, MG Chemicals 835 (liquid RA), is available in small bottles that are reasonably priced which is very useful for hobbyists (125ml and 1L sizes), and is easily found in North America, the UK and EU. Not sure about other markets.  :-// Kester flux is excellent stuff IME (186, 186-18, and 1544 are all liquid & rosin based). Unfortunately, Kester only offers their fluxes in disposable pens or large containers (1gal & larger, up to 55gal drum). It's readily available in the US, and although can be had in the UK/EU, it's expensive as it's usually shipped from the US from what I've seen (Farnell).

  • For paste, Kester RF741 is a modified rosin no-clean that's very nice to use (comes in a syringe). Amtech is supposed to be good as well (also a syringe), but the real stuff is hard to find as their distribution is nearly non-existent (highly counterfeited too).
  • FWIW, I usually use liquid in a refillable brush pen as it's less expensive and gives me better control than the disposable pens.]
