Hi Aditya,
????????????????????? There is no easy answer to this question, it depends entirly on what
you intend to solder. How ever for the average hobiest, I would sugest
something in around the 60 to 100 Watt range as far as power is conserned.
Dependant upon which type of iron you buy there will be a huge range of
soldering iron tips. Which one you select will be nearly entirely personal
preferance. Three coman tip shapes are: Chisel, Pointy, and flat. I
personally prefer Chisel, around 2 to 5 mm at the tip. But this is becuase I
do alot of surface mount rework as a job.??? Cost is also an important factor.
No use dreaming about that $1000 dollar soldering iron with all the great
themo controls and fancy tips if you dont have the money. Personally, I
started off with a 200 watt Berko Iron with a 15mm tip 2mm diameter solder,
and bakers flux. And yes I soldered PCBs with it. Now however I use a Weller
TC-202 60W iron, with a variaty of tips. This is more than adequate for my
curent use. As an obsevration. I've been soldering for around thirty years
now, and in my experiance, practice is what counts rather than the tool. I
have seen some super educated people make a total mess with some really great
tools, and my wife is capable of doing some of the best most consistant work
I have ever seen with some real shit equipment (not mine) and no formal
training.
????????????????????? I feel the best advice I can give you however is test a few diferant
types of irons before you settle or buy one for yourself. If you have friends
with soldering irons, use thiers for a few hours if possible. Does it suit
your hand?? Can you make a good joint on a variaty of pads?? Desolder using
some desolder briad, How easy is it????? Does it do a good job with ease?? How
easy are the tips to change?? If possible experiment with differant tips, and
solder. If it's a thermostat type, (Adjustable) how easy is it to adjust?? Do
you like the controls?? You will hear all sorts of advice from all sorts of
people as to what the "Perfect iron"??? might be. However, largly I think is is
personal choice. Dont be afraid to try a few things out.
