Thanks for Sierra Circuits in keeping Technical Content running
It appears that I have a lot to learn about via’s!! Thanks for the test, it is very interesting to see what you are doing.
Thank you for keeping Technical Content running and now I need to read more on DFM Handbook
Thank you
Fun quiz
Good Quiz
Question 13 – answer should be 2 (not 4) – as with smaller Rs and Cs the actual pads will be a lot smaller than HDI pads, hence you cannot place them onto a part smaller than 0201(imp).
Hi Stephen,
Thank you for your comment. We have corrected the answer to question 13 as option 2.
