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 the last 15 years i have been using the Hako 924 series iron

    at the start i was using the pencil tip then i found the Knife edge tip

    the main advantage i found with this tip was better control of heat 

    then when working on industrial boards usually 3mm thick

    or with large ground plans i would ad a 2nd iron with knife tip.

    most of the time i am using 0.9mm 60/40 solder 

    even when SMD ic's

    Using x10 or x15 glasses of course

    tried using different brands of 0.5mm solder but just not the same quality.

     

    Some good practice for a beginner is removing parts from different old boards 

    then refitting them

    When I started working on down hole servey tools 

    the manufactor has specified solder with silver content 

    to keep up with the boards when they are down the hole in 130' C enviroment

    the next day i need to clean up my tip. 

    if you want to challenge your soldering try doing Cheap plastic connectors 

    Hint put the plug into the socket then solder the plug pins.

    only the good will try wiring a lemo FFG.0B  7 pin plug with heat shrink on 0.5mm core
