hello, i have a faulty board with SOT-23-5 component on it marked APKK. excluded everything else. does anyone know what component this may be? I cant find it online...

Is the same marking protocol used when identifying 0603, 0402, etc.. components? For instance, would a 27.4K ohm 1% resistor still have four (4) characters to identify if the body color is black? Any feedback is appreciated. Thanks.

Hi, Do you know if there is any standard that specify that a component manufacturer shall mark a BGA component in the corner where you have the ball A1? Best Regards, Lars

The alternatives are ink-jet and laser and you'll spend way over $20,000 for that solution! Screen printing is still the best at ROI when doing multiple panels and lot's of legends. We used a rubber stamp inked with Hysol for smaller quantities and o

Interesting. We are placing a camera that the marking is on the bottom..... No place to put it on top! The problem with the question is the word shall! I think the answer to the question is yes there is a standard but..... no law to enforce it....jus

Available on the web, JEDEC PUBLICATION 95, DESIGN GUIDE 4.14, Ball Grid Array Package (BGA), Figure 4.14-3, Note 10: A1 corner must be identified by chamfer, ink, mark, metalized markings, indentation or other feature of package body, lid or integra

we are considering laser marking all boards in a panel with a unique identifier that will eventually tie in all the component data used on the board. We were wondering what numbering schemes are used in our industry other than a unique MSN (manufactu

If this component is laser marked, you could just spray conformal coat on it and the marking will disappear.

Any ol' acrylic or urethane will work. It's possible to remove these conformal coatings. We've never removed coating from components to determine if the marking is still unlegible

Steve, According to the Yageo site a .1% 0805 component would have a 4-digit code just as the 1% do. Jerry
