"I can hardly disagree with you on that but I think some if not majority are counterfeit components because they are of less quality and risky"

Wale, still I didn't get what is counterfeit components. All components have their own identity, some with high quality and other with medium or low quality; which can satisfy all level of components. So customers have the choice to select all type of components based on their application requirements and thickness of wallet.

@Hailey: Also it is important to find out the response time as well. Errors do occur but if we cannot provide a solution in quick time then the service is poor. If the response time is good then the users will not feel the issues in a big manner.

@hailey: Yes what matters is the time frame of errors. If it's a constant issue that happens from time to time on a regular basis then it's a big issue indeed. After identifying the error rate the solution can be planned properly.

@Flyingscott, it would be interesting to figure out, based on how often problems occur, how long it takes to solve if the problems are marked and unmarked and how much is saved by not marking, whether it's a real savings to go without.

Having been through the troubleshooting phases of product development, I would say without component markings may lead to doubling development time! And it can be catastrophic at times.

>>It will only be an issue when there is a problem to solve and the component needs to be visually verified<<

That states the importance of color markings of the component. Unless there is a unique means of identification better than that, i dont think it should be unmarked for now. Any modern identification in offing?

"Quite surprising. How the quality check department of Digikey would have allowed these resistors or capacitors to go to the customer end. No wonder counterfeit is such a big industry globally."

SP, in certain cases counterfeit components are at par or more in quality than original components. W e cannot say such components are counterfeit because they can be substitute for the originals.

0402 and 0201 - can i see them?

Now, I need to use many of 0402 and 0201 in new design. These parts or so small, it is little difficult for me to see them.

I suggest some alternate method of identification. Like RF tag as suggested in some other blog.

Practically there is always a problem on the board when youa re trying to bring up the board. Markings are the must.
