To remove the Resistance Value Marking on R-Chip sizes 0603/0805/1206 for the purposes of reducing unnecessary chemical usages for environmental protections. To identify the product resistance value each single reel is labeled with all relevant data and will continue serving the purposes. As for the product, performance, features, specifications, manufacturing process and location remain the same. So, the elimination of the marking on top of the product itself has no impact on the product functionality and reliability and customer can use it for all current and future applications as already done.

Yageo has provided no resistance marking on R Chip 0402/0201/01005 and on the entire MLCC family ever since. Given Yageo has been devoted to being eco-friendly, we decide to eliminate the marking on the R Chip of the sizes of 0603, 0805 and 1206 as soon as possible. There will be a short period of time that both types of the products, with marking and without marking, co exist while we are changing the production lines one by one. We highly appreciate your understanding that we may ship the products in parallel for some time. Yageo commits that we will make full efforts to shorten the overlapping period as much as we can.

One of the FAB boards I submitted looked great on Eagle screen.  But when I got my “real” boards back, I see that silkscreen text was too large, and overlapped on some of the components.  What happened?

It seems I forgot to change the text type to “vector” from “proportional”. So it looked great and fits in the space alloted when viewing my board in Eagle. If I had viewed my gerber files, I would have discovered the problem.

So began the quest to find a Gerber Viewer for OSX… which I discovered was difficult. I spent too much time chasing dead end leads. Of course, #1 priority was the price….. FREE.
