Who inventes SOIC16?

Who inventes SOIC16?
I learned "the hard way" and must check data sheets and detailed delivery information before I ordering next time.
I have to buy a powerful magnifying glass.
Maybe I also need to buy a new soldering station?
Probably I need to buy thinner flux wire.
1 mm diameter seemed to solder all the contacts together

SOIC is huge, what's the problem?

Nah, SOICs are for industrial plumbers, real nerds hand solder BGA and WLCSP

Are you serious? You do need to update your setup and skills if you can't solder SOIC. It is HUGE by modern standards. To the point, where I consider it to be more work to move soldering iron between the pins an try to use smaller packages.

It's possible that SOIC is hard if your hands shake or vision is too poor. But that would mean (almost) any other SMD component will be too difficult.

Perhaps he means MSOP, not SOIC package

To be fair, I am sure we all had a time when we switched from through hole to surface mount.

I remember thinking even 1206 were small and a PITA on my first project with surface mount.

use the force Luke, (and then the magnifying glass for checking bridges) may the force be with you.

It certainly is difficult to solder an SOIC chip onto a DIP footprint!

J/K. OP, when you solder chips onto a printed circuit board (rather than trying to solder little wires to each pin) you will see SOIC is very easy and maybe TOO big.

This is partly a function of your soldering iron tip shape. You could probably stand to buy some liquid/gel flux to put on your joints, and to buy a tip or two to help out. Small bevel and chisel tips are probably going to help you for what I predict you are doing (protoboard, manhattan, fly-wire construction).

Google for 'drag soldering'  The trick is to use plenty of flux.  You can buy some here:

This thread is loaded with great advice...

except he obviously isn't soldering to a pcb/footprint.

Drag soldering doesn't even really help on SOIC.  Maybe if you're using a monster big tip.  I typically solder the pins individually!

Finer pitch is very practical to drag solder though.

Drag soldering SOIC is a piece of cake. Even if you don't have a specialized tip, chisel will work as well.

I often solder them directly to 2.54 proto boards:
Just lift every other pin, solder down the remaining ones (now at 2.54) and use small wire for the lifted pins.

Thank guys for advise.
Yes, I tried to solder wires at the pins. It looks like an alien spider.
Today I will check for any short circuit.
It seemed I need to leave the “through hole” road and instead go for tiny surface mounted solution.
That of course if the amplitude of my hand frequency permits it. :P
I have order breakout PCB for SOIC-16.

Who invented 4 pin qfn packages, probably an rf wizard wanting less parasitics.

As far as soic and msop, reduction in die size meant smaller package sizes could be used. Which costs less in materials in the long run. And a higher packaging density.

Under 0.5mm pitch, things get hard with pins, as they get too soft.

it seems IBM from History Lesson. now find who invented all these but for what? life is too short.

By todays standards SOIC is huge and even MSOP seems big in terms of board space. With a good magnifier a fine soldering iron tip and 0.25mm or 0.3mm diameter solder you will find it isn't too bad. I've been re spinning a board design where most of the packages are 0.5mm QFN or DFN and the "biggest" package is 6pin SOT23 which I have to change to DFN if I can find an alternative part. It's even getting to the stage where I need to look at "hole in pad" PCB manufacturing to gain some additional board space. I'm finding the hardest part is getting good results from the paste stencil and then hand placing all the parts.

The conclusion of my Q is that I feel really behind regarding electronic technology.
I probably will stay at “through hole to surface mount” and SOIC  until am master it.
But I must make an amusing comment.
So if I understand the correct technical progress toward future! 8)
In order to soldering the next generation electronic components I need:
1.   Electron microscope
2.   Soldering iron tip of 200 nm
3.   Steady hand
Take care

Sure you don't need that (look at the picture). Even if you meant digital microscope, it sucks for soldering. Optical stereo microscope is much better for the task.
EDIT, ok I didn't get the joke because missed iron tip size. But seriously, there are a lot of components which are just a bare silicon die (second pic) and they are soldered a usual way. By usual I mean reflow soldering. I hand solder them with hot air without an issue. Soldering iron is completely useless for any BGA or LGA type package (unless you make a dead bug).

Perhaps you can also start to dab (pun intended) into solder paste and ways to reflow it.
Warning: a steady hand is still required, unless you can afford a P&P machine
