Revision as of 11:48, 6 October 2016

Tools on dx.com

  • Centre Punch
  • Dial guage?
  • Dowling Tool (for right angle drilling).
  • Flexible Coolant Pipes
  • Mitre Box. (Have one)
  • Try Square. (Right Angle)

Molding/Casting

  • Transparent Silicon

Wood


  • Bolts/Nuts/Threaded Rods. M3?, M5?

Electronics

RepRap Gen7 Electronics

  • Vaccume Desolderer
  • Tiny stepper motors (5 are like $4)
  • Transistor/Capacitor tester ($12)
  • 2x Wireless modules. ESP8266 ESP-03, About $3 on ebay. (Remember to look up voltage divider). Need USB Serial programmer, FTDI with 3.3v support.
  • Photodiodes

Solder

Element14 - DURATOOL SOLDER WIRE, 63/37, 183DEG C 226.796g - 0.64mm/0.025"- $31.44 + shipping (free on orders over $45, Actually seems like shipping might be free anyway...)

Digikey MultiCore C502 227g, 3% flux, 63/37, 0.015"/0.39mm - $25.01 + $35 shipping...

Digikey Multicore Infos

110 GRAM REEL OF HIGH QUALITY 0.7mm LEADED MULTICORE SOLDER - $8.72 + $5.24 shipping.

Loctite 60/40 C511 5C 0.46mm 0.25kg $27+$11

Multicore X39 60/40 No Clean Solder Wire, 0.56mm, 0.25kg $26+$11 - According to Digikey Loctite is the new name...

Multicore Size 10 Reel Alloy Solder O.7mm Diameter 60/40 0.7mm - $27.00 (free shipping?)

Multicore SOLDER wire 250g 0.7mm - 60/40 ERSIN 309???- $28


  • 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)

Desolder Wick

Flux

MG Chemicals 835

Digikey Fluxpen - Digikey has basically no flux choices

Mouse Flux choices

This flux pen... - $13.10

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.]
