How do you choose soldering iron tip size and solder wire diameter?

HKPhysicist

Hello Friends and E/E Engineers,

I have bought this solder bread box for my new project.  This is my first time to solder my own circuit.

I think it is the universal standard 0.1" pitch holes board.

According to your precious experiences, what soldering iron tip size and soldering wire diameter do you choose?  Primarily, I do pass-though-hole parts plus few SMD. Pray

I did try a soldering iron tip in 1mm diameter and solder wire in 0.8mm diameter on this board but my solder joints seem too fat Penguin , not as slim as theirs shown here:

    Hello,

    For those holes and thru hole pins with my equip. I  use the dull pencil tip,  0.025-0.035 60/40 solder, and set iron temp to 250-275C and often never have a problem.

    It  wets fast with good solder flow all around the pin/lead. I try my best to get in and out quick. I have found with a bit more heat there is better flow and its faster.

    I do not use flux much for thru hole stuff but for SMT I use the 559 flux and have not had many issues.  I worked on some led's on aluminum and had to switch to a chisel tip and crank 

    up the heat to 400c for fast get in and out and that was after I used the bent fine pencil tip and first melted in some low temp solder then came in with the chisel. It was my first time with

    led SMT strips/bar RAB lighting led bar sold on Goldmine Electronics. The Al really sucks up the heat. Lead free also needs more heat.

    Short and fast is get in there and play around only way to increase skill set, have a good set of tip sizes along with some low melt solder.  I use the Yihua 852D+ station.

    Have fun  and good luck.
