I don't own a laser printer right now. I sent samples to some vendors and I couldn't read the codes. Have pictures of 2D codes on white solder mask? Thanks

I agree. The bar coded label you use should not be affected by the solder mask of the board. The label should have sharp contrast between the segments of the code to modulate the returned light and allow the reader to discriminate between light and

Trying to find a laser marking machine. Thing is that most of my pcbs have white solder mask, so the when trying to read the 2D code is difficult due to the lack of contrast. Any idea? a different technology? regards

Our AOI machine can save various views of the same part number since we all know that different manufacturers will mark parts differently, some manufacturers vary their own marks. We get parts from the same manufacturer but different date codes that

On big chips, we use a tape printing device, I think it is a Brother PT1750. We have a small device, though, that is in an SO8 package, and the only thing we've come up with is to scratch a product letter code and the program date with a stylus. Th

Hi Robert, Try looking at www.marsport.demon.co.uk/smd/ This site contains a list of html files with all marking codes known at this moment. Your example of a transistor with marking code 8A can be a 3V3 zener diode or a npn general purpose transi

I am in need of some help. I was wondering if anyone knew of a site or book that I can get that will tell me what the marking codes on smt components are. Such as diodes and transistors. Any help offered is greatly appreciated
