A reputable supplier will identify the level CLEARLY on the packaging and in the datasheet as well. If they are KNOWN to be MSDs, I'd be suspicious if they aren't marked. Or, they may not be MSDs. I don't think it's required to ID them as "M1" if n

An ICT solution seems to be overkill for what you've described. What kind of volumes are you hand building? How many components are not marked? What is your current yield with the process you are using? What is/was your yield prior to implementing m

Hi All, I would like to ask some help from you. It would be very important for me to identify a bad IC. It is located in a 2,4GHz radio frequency receiver, maybe the IC is some kind of low noise amplifier, but I'm not sure about it. It has 5-pin, see

Hello guys I am back! Guys I have a problem with the laser marker here, we use the laser to mark a 2D barcode on the pcbs for traceability, but for some reason since yesterday every time it tries to connect to the database to get the serial codes an

I think you are going to struggle without a laser designed for PCBAs (Asys, XJ Link etc) as they are designed to just burn into the resist and give good defininition, then readback to know you have a good mark. Key tips for our experience: Datama

Wow - 11,000. We have 8K-9K, and we have had three people working on it for the last 6mos, around their other duties. We aren't done. Some MFR's changed PN's. Some add G, some add LF, some add NOPB, some add Z, Some add a "+", etc. Some have no d

I tried to look for "H890" on Internet and went nuts, (Thanks to Google) I would think H890 is part of a diode manufacturer part number. Have you tested it for a diode function? or maybe you have this is why you want a replacement. Tantalum capacito

We do the following things: 1.) RoHS PCB:s is marked with a code. This is to identify that the PCB:s itself are RoHS compliant. 2.) If it is a true RoHS PCBA; we put a printed label with a green "texture" on the PCBA. 3.) If it is a mixed PB free/PB;

| I'm doing some basic research in trying to understand the purpose | and drivers that cause bar code (or other) marking of PCBs. I would appreciate any knowledgable volunteers willing to speak with me -your name, number, the best time for the call-
