The Hakko soldering iron tips are great.
It is nice to have an assortment of shapes and sizes for different soldering jobs.
As I mentioned in a previous thread, this is my new goto soldering iron tip of choice:
I shouldn’t have used goto ???
I can’t remember if this was brought up in here or in the previous thread, but Hakko has some great references about choosing tips. This page details the uses of the different shapes in the T18 series (Weller probably has a similar page, I just don’t have one). The bent one you posted is type J.
My vote for the champion of the “unexpectedly useful soldering tip” category doesn’t go to the crooked type J, but to the type K Knife tip.
Yes folks, this is not a cutting attachment, it is a proper soldering tip. Hakko described it’s advantages thusly:
This type has a shape like a knife and is capable of soldering by applying the tip in 3 ways: line, face and point.
It is used for soldering at narrow pitches, correction of bridging and drag soldering.
That first image in there is just awesome; through hole drag soldering. I tried it last night on a 20 pin ZIF socket and it with the ability to start heating the next pin while one is wetting it probably took less than 15 seconds to do each half with the fine solder I was using. If I used my thicker roll it would have probably been a hair faster.
I can’t wait to try a TQFP or maybe even a lead-less package with this. I just need to make some progress on the parts of my projects that I’m stuck on.
