I would like to know if it exist a croos reference book for marking code on smt device? I'm fixing a unit now and try to know what are the following devices: The look like mosfet and are mark like that "A2sKG",there are a horizontal line on top of "s

If it is necessary to define the type SMD semiconductors on its code of the marking (marking code, top mark) - visit the site (no www!)http://users.zebratelecom.ru/~smd_marking The having read article "rules of the marking" you get the full pres

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

Steve, I finally played with it enough that it is working again. I ended up with Edge Threshold: 19; Intensity Threshold: 60; Offset: 200; Gain: 16 The problem seemed to be with the Intensity Threshold. I was not getting an error code on the screen

Chuck: Your best resource is the Symbology Research Center in Huntsville AL. In is a research and development facility run by RVSI Acuity CiMatrix, the folks who invented the Data matrix (DM) 2-D code. This facility is unbiased as to technologies and

We use an Intermec 3240 Thermal transfer printer and print on polyimid label material that survives the reflow and wave solder (top side only) process without turning black. Labels run around 3-4 cents per depending on the size (We found Imtec label

Hi! We're noticing white spots on 2 PCBAs after the selective soldering & DI Wash processes. ----Facts---- 1) The marking is on all boards, irrespective of date code 2) It only happens on leads that have been selective soldered 3) The pattern of w
