Thanks a lot flipit, I am not directly involved in this "problem" but is my friend that have his CM rejecting PCBs because it says the "+" mark (spokes lengths) are out of tolerances. It seams CM bonder's require tolerance +/- 0,05(? not sure). I d

Hi i am looking for IC60 as shown. It's top mark is 4L1 L74 (two lines). 8 pin package.I suspect its somekind of comparator/amp http://s18.postimg.org/iw5ucp4qx/photo.jpg Many thanks in advance

Thanks for the info on the Hydra tubes that will be helpful. I found the answer from one of the Mydata techs. The Camera needs the hydra head to go slower then 1.9m/sec and the setting was at 1.8m/sec. They found out that even if the machine was set

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 transistors and are mark like that "8A"

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

Hi Scott, Mark Wang just manufactured a 8L(2+4+2) HDI pcb prototypes for me,the PCBs min trace width/space is 2.75/3mil,I worried about the quality very much when I place the pcb job to Mark.but in fact,the 8L(2+4+2) pcb's quality is very nice,I w

We have started switching all our PCB marking from labels to Laser marking. We have a silkscreen patch put on the boards then use a CO2 laser to burn the mark off to produce the barcode. Our marking downtime has gone from an average of 8 hours a we

Helllo, our company using yestesh BX AOI for board inspection. It is problematic to detect component description in characters that is rotated 45 degres (SO8 and other) with marking inspection, maybe someone can help how to fix it? Characters that ro

We measure the thickness of solder paste printed onto PCBs as a control of the printing process. Generally 6 thou stencils are used and give between 6.2 and 6.8 thou. What thicknesses do other users get? Cheers! Mark
