Introduction

This repair will require using a soldering iron to remove and replace damaged Ethernet ports. This is very delicate operation, involving 8 contacts per port. Be very careful as to not gob the solder around, and do not damage the Printed Circuit board.

  • The PC board is loosely attached to the plastic base. Note the micro-soldered terminals on the Ethernet ports. These are very small and require significant expertise to desolder and replace.

Image 1/1: Prep your desoldering braid by pulling it into a shape that will allow it to contact the solder on the baord itself.
  • Do to modern manufacturing, you will need to cover the area in solder flux; it is messy, so be careful.

  • Touch the soldering iron to the top of the contact after it has heated sufficiently; the flux will melt, as will the solder, and both should flow into the desoldering braid.

Image 1/2: If neccessary, you will need to make a custom tool to touch all of the contacts at once. This one is made of bent copper wire and can replace the tip on a pencil-style soldering iron.

  • After removing all of the solder from each terminal, you may try pushing out the ethernet port. If it won't go, you need to remove more solder.

  • Once the ethernet port is removed, you may replace it (or anything else you had to remove), and solder it to the circuit board.

  • You can find many fine soldering guides online, here is a reccommended one: http://www.wikihow.com/Solder-%28Electro... Remember to add flux to the joint prior to soldering.
