Hello!
I'm looking at different JBC tips since I purchased (and am currently waiting for) the Aixun T3A. I'm currently trying to decide between the different tips, and I wanted to see if I was going in the right direction. I do some SMD work down to 0402, and I also deal with up to 8 layer boards with large ground planes, so I'm trying to get a good variety of tips. So far I'm thinking of the following:
C245-029 (0.4mm bent conical) - This seems to get recommended a lot for small SMD components down to 0402's.
C245-406 (1.2mm x 0.7mm high temp chisel) - SDG Electronics recommended this style for general purpose uses, and I wanted to give it a try for standard DIP components and surface mount chips with wide spacing
C245-965 (1.9mm spoon)- This gets recommended a lot as well as a general purpose tip for a lot of different applications and for reflow soldering. I have a couple fake T12 spoons, but everything I've read seems to indicate that fake tips don't get the thermals right for spoon tips.
C245-966 (6.6mm x 1.8mm high temp chisel) - I want something big for soldering big MOSFET tabs (9mm wide) to ground planes. I think that this is the right size for this, but I'm not sure.
I'm wondering if this seems like a good variety of tips that should satisfy most applications, and I'm also wondering what the difference would be between the following three tips as I want to add one of the three:
C245-770 - 2.4mm x 0.3mm slender cone-shape chisel tip
C245-741 - 2.4mm x 0.6mm thicker cone-shape chisel tip
C245-759 - 2.4mm x 0.5mm narrow chisel tip - not cone shape
I'd like to be able to use one of the three tips for general-purpose SMD with large components and for soldering up to 12 gauge wires to boards. I'm wondering what the trade-offs are for the different 2.4mm chisel tips. I know that you want as much metal as is possible behind the tip for good thermals, but I'm wondering if the narrower tips offer significantly better dexterity. I'm also wondering if the thermals are much better or just a little better on the thicker tips. I've liked using the Weller RTM 022 s at work in the past, but the micro soldering tips are narrower overall, so they're pretty good for dexterity, and I don't think that it would be a direct comparison.
Thank you!
