You will find lots of dust, and sticky gooey residue on the PCB. The gooey residue is heat-sealant from the thermal pads that lie on the R36 current regulators. The heat sealant often leaks from the thermal pads and drips onto the PCB. The gooey residue captures dust and should be cleaned away.

  • After blowing with compressed air, use an antistatic brush to dislodge grimy chunks. Do not use any brush that may be available. Most brushes cause static charge to build up and can damage the electronic components.

  • On some YouTube videos you will see people cleaning their PCBs and the inside of their computers with vacuum cleaners. This is risky for several reasons. The plastic tubes of typical vacuum cleaners can carry electrostatic charges. The brush tip of domestic vacuum cleaners is unlikely to be made of anti-static material.

  • Furthermore, you should avoid using mains-powered equipment while wearing a wrist cable connected to ground.

  • Finally, typical domestic vacuum cleaners are large clumsy machines that can cause mechanical damage. Precision is required here.

  • Note: You can see the black plastic stays on the northbridge heatsink in this photograph.

  • New line.
