Production of High frequency Crystals.
Hi Group!
My question is about the production of high frequency quartz crystal blanks. I have lapping and polishing machines with me, i made quite a few number of crystal blanks with frequency upto 20 MHz but above that around 30 to 40 MHz the blanks tend to break a lot, so i would like to get some expert advice regarding which powder to use in lapping, which carriers and other machine parameters. The machine I have is Lapping machine from Hamai. Hope Someone can come up with some good suggestions. Thanks in Advance. |
