Ruining of 16x2 lcd pins while soldering.

Hi, my name is Pratyaksh Asarsa and i am a beginner.I bought a new 16x2 lcd display and tried to solder male header pins to the lcd screen but the stuff got messed up.It got worse when i desoldered the pins as the solder pads too get removed from the pcb.Please help me by suggesting the alternative pins of the lcd. For eg.this pin is connected near that resistor or component.I have also tried surfing over the internet but didn't get success.You can also refer to the images of the ruined lcd pins that i have attached here.Any help would be appreciated. Thank You.

That is not a pretty sight. Clearly your soldering skills still need some development.
You may be lucky in that you might still be able to use a new 16 pin header and lay it flat across the solder pads (maybe on the back face of the LCD) instead of trying to push it through the holes, and solder it that way.

You might be able to fix the holes (remove the solder) if you had a desoldering iron or some solder wick to clear out the holes.
However, while those are not expensive, about $15 USD for the iron and $2-4 USD for the wick, both of those are more costly than a new LCD which is under $2 USD on ebay.

If you were soldering a simple 16 pin header for using the LCD in breadboard vs an I2C backpack,
then my recommendation would be switch to using I2C for the LCD as it is much easier to use and wire up.
All you need is an i2c backpack which is under $1 USD from ebay.

You can also order the LCD with the i2c backpack already soldered on it from ebay starting at about $2 USD.

Then, use my hd44780 library which will auto detect the backpack and the pin mappings to the LCD.
This will give you a plug and play LCD that only uses 2 arduino pins and 2 pins for power.

Maybe you can solder wires directly onto the ruined spots of the display. You need to wire only 1 thru 6 and 11 thru 16. I recommend a soldering iron with a very fine tip
