i-Extruder is wonderful !I backed the i-Extruder twice, once for the campaign that didn't make the goal, the second time for the one that DID make the goal. Since then, my i-Extruder has been sitting and waiting patiently for my projects to require it. That day was today.
I switched the type of flux I've been using (MG Chemicals liquid rosin flux) for Amtech NC-559-V2-TF Tacky Flux, recommended by Louis Rossmann in NYC, who uses it for board-level repairs on Apple motherboards. I love the stuff, but I got the big 30cc syringe, and it was just really unwieldy to use. So I pulled out the i-Extruder, filled a 10cc syringe and hooked everything up. It works perfectly, delivering just enough flux, then pulling back to keep more from oozing out. And since I do plan on getting into SMD components soon, it'll come in handy for solder paste application, too! (I have both hot air rework station AND a ReflowR programmable reflow plate, but haven't done enough SMD to really take advantage of them yet. But soon...)
This device is a real godsend, especially because I have difficulty with my hands due to a spinal injury. Squeezing the plunger on a syringe is possible, but painful, so this really helps me with my electronics work!
Thank you, and I hope you're having a lot of success! I just sang the praises of the i-Extruder to a worldwide mailing list of ham radio homebuilders and modders, so we'll see if they think so too and order some!
