Looking at Small Electronic Components

By on September 7, 2012

Are you having problem looking at small electronic components? Even in my 30s i have no problem in looking at the small SMD components but reaching 40 plus I have to change my spectacle to the multifocal one so that I do not need to remove my spectacle when looking at small components. Is this a disadvantage for repairers when their eyesight have problem? Definitely no because one can always use a magnifying glass to help to see the small components. In my workshop I have few types of magnifying glass. I have the big and the small magnifying glass and the power ranging from X 4 to X 40! I even have one that is rated at X200 but that is not necessary. A x10 magnifying glass is good enough for most of the troubleshooting work.

What about your eyesight? Is your eyesight still good even in the 40s, 50s …..?

    Hi Jestine,
    I have read somewhere that the eyesight start declining  after 40 by nature.

    As time goes by I find that I have to use amagnifying lamp  more often. I use the one with the 22W circular flourescent lamp to light up the area being viewed:
    Also, I use the type that is fitted to your head:
    i hope that links are OK, I am not trying to advertise, just show the products that I personally use.

    WOW X40! That must be the type with stereo viewer? I used one a work it was a trinocular, the third optic was for a camera so defects found on PCBs could be saved to the computer and sent to the manufacturer of the PCB for quality control.
