  • Circuit Board Identification

    I was wondering how these boards would be classified. More specifically, Ben under which class would you purchase them?

    I have numbered the items in the pictures

    1: CPU from laptop

    2: CPU from laptop

    3: CPU from laptop

    4: CPU from Apple G5

    5: Motherboard from a photocopier

    6: Motherboard from a medical laser

    7: from a server rack

    8: White Ceramic Gold Cap and Legs IC

    9: White Ceramic Gold Cap and Legs IC

    10: Epoxy/Plastic ICs with Gold Legs

    11: DLP with Gold legs, most of them are covered in tin from being soldered.

    Also how are hard drive boards and cell phone boards classed?

    My latest video series covers the grading of most boards, part 2 up soon.

    1. Looks like a video card, mid or maybe high grade
    2. same
    3. same
    4. Slot CPU
    5. High grade but could slip into motherboard
    6. high grade
    7. maybe server grade
    8 & 9. my 8000 series grade
    10. just ic chips
    11. ccd sensor, they vary and might be worth around $40 kg

    hard drive & cell phone boards are graded as they are, but not many buyers here in australia.
    I grade them by the board itself, from mid to telecom, modern h/d boards are just mid so most sell complete hard drives.

      Thanks for the clarification. Another question, do slot cards have to come from computers/servers or do they simply need gold fingers? For example these two boards came from an old CRT TV and a medical laser.

        Yep, slot cards when they're that size, really big boards with gold fingers would just go as the grade the board is overall.
        But anything under the size of a regular pc motherboard with fingers would go as slot.
