how to easily fix broken cpu pins

[Lii]

what you will need:

cpu with broken/bended pins

3d printer

soldering paste

hot hair gun

gold plated pins

 

it doesn't matter how you do it, you can turn around with different workflow, if you don't have a 3d printer, you could just use a dremel and a piece of wood for example, or use some foam to do a mask, the point of this whole thing, is to add some new pins, it doesn't really matter what tool do you use

 

 

get a pinout mask for your cpu, or do one

 

it doesn't matter how you do it, but you should have a result like this, it's important that the image is monochromatic

 

scan/do a photo (or find it online) of your cpu pins, put it in Photoshop or whatever else program

correct the lens distortion if there is any

remove the golden areas (ergo the pins), convert the greenish (the pcb part) area into black
 

 

get a 3d mask with a cpu holder or do one

 

get the previous monochromatic image, put it in any decent 3d modeling tool, extrude it along the z axis, 

also do some type a slot for the cpu, so you can allign well the holes with the pinout slots
 

 

now get the cpu, remove all the pins, sandpaper it, so it's all nice and flat, (or sandpaper the new pins later on, so they are in the same level)  just heat up the thing to remove the pins

 

put in the flat mask, use it to apply the soldering paste

 

put in the 3d mask, flood the holes of it with golden pins, heat up the whole thing, remove the 3d mask, and voila' , you will have a cpu with straight pins
