Will SMD resistors marking become history?

    "Company YAGEO announced its intention to remove marking of RC/AC
    0603,0805,1206 SMD chip resistors from July, 1-st, 2013"

    Just wondering about your opinion....

  2. Environmental reasons? Is white ink toxic?
    We use KOA or Vishay anyway. doesnt really affect us.

    ** Speaking as a service tech - it sucks big time.

    Any maker who ever wanted to prevent copying or repairs by anyone but a
    chosen few knows that all you have to do is remove the part numbers from all
    the semiconductors after manufacture.

    Thankfully till now only a tiny, paranoid few have ever done so.

    SMD products are hard enough to service even with fully marked components,
    this move will make it impossible except with the full co-operation of the
    makers and their overseas agents.

    If pigs could fly ...

  4. Folks are doing fine with the smaller form factors, which have never
    been marked, so the thought is why do we need any continued marking on
    the larger form factors?

    The intelligent among us will survive just fine.

    Might as well strip markings off all the other parts too, for the same
    reasons. Who needs to know what parts are which? They're all exactly
    the same, right?

    What's all this part-marking stuff anyhow?

    With all this in mind,

    is there a web page with SMD markings to real part numbers ??

    I have some parts that I misplaced the data sheet...... ;-)

    Maybe they will start using color code.

    In many ways, resistors and capacitor markings are even more
    important. If you mix up the feeders of other parts the guy watching
    the reflow oven has a chance of find a big problem early in the
    process. ;-) Not so much with resistors and caps.
    I never look at them (resistors and caps) but I'd think QC could use
    the information.
  9. I had a $350 device fail, which I sent back for repair. They claim
    it's "not repairable". Head office is in Taipei, service depot in the
    US. I bet it's nothing that would take a decent service tech more than
    15 minutes to fix- it works for a while then cuts out (probably a
    power supply fault of some kind causing regulator shutdown). I had it
    returned so I could look at it further.

    Maybe I should trace out the circuit and post interesting bits of it,
    since they don't seem willing to repair their stuff or supply
    schematics. It's an RTD->Ethernet module.

    ** Hmmmm -

    has anyone thought that a " body- end-dot" system might be good for SMD ??
