    How do I identify Pin 1 on a chip with no corner mark

    The white strip on the left side of the picture looks like a similar indicator to the notch in most ICs, hence pin 1 would be on the bottom-left of the supplied picture.

    Component Orientation and Polarity - Sierra Circuits

    Capacitors typically have straightforward polarity markings: a plus (+) sign for the positive terminal and a minus (-) sign for the negative terminal. In the below image, shorter lead and line arrows indicate negative terminal.

    What is the White writing on a circuit board called?
    The white writing that you typically see on a circuit board is called the silkscreen layer. The name comes from the printing process that has been around for about 1000 years. On the silkscreen layer, the designer can place a dot next to pin 1, or a line drawing of the chip. Pin headers may have a square around pin 1.

    How do you identify a chip?
    This chip is placed in a socket and uses a clipped corner to prevent improper insertion. Notice that the dot is on the side rather than in a corner. This marks pin 1 and the other pins are numbered counterclockwise from this pin. The other chips are DIPs and the dot marks pin 1.

    What are IC clock markings?
    ICs are available in various package types (DIP, DIL, SDIP, SO, SOIC, SOJ, SOP, SSOP, and TSOP). Below are the typical IC clock markings: Notch: If the chip has a notch or a scallop on one end, pin 1 is located at the bottom left corner of the chip when the notch is on the left side. Pin 1 marking on an IC using a notch.

    What does a black dot mean on a hcpl-181-000e?
    The larger black dot denotes pin 1 for HCPL-181-000E. Often pin 1 is in a corner of the chip, and it’s only that corner — not the pin itself –that is marked by the small circle or triangle. When someone get a new component, one of the first questions they often ask us is “what’s the pinout?”.

    How do I know if a Broadcom chip is notched?
    The white silkscreen on the circuit board shows an exaggerated picture of this notching, by the lower-left corner. The 486 is a good example of a chip with a notched corner, while the 68030 has a gold stripe to indicate pin 1. This Broadcom chip has a dot by the corner with pin 1, but that’s a pretty subtle mark.

    How do I know if my IC is pin 1?
    Pin 1 marking on an IC using a notch. Bottom-side beveled edge/chamfering: If there are no distinctive markings on the chip, check for one edge of the chip to have a chamfer or bevel at a 45-degree angle. Position the chip with the chamfered edge as the bottom edge. Pin 1 is at the lower-left corner.
