Dear all customers, Kindly reminding that the Chinese festival holiday in Weller is 1st Feb to 19th Feb and production will be closed then, please schedule your order beforehand to avoid any production delay due to our holiday.

Any other RF substrate like taconics, etc. that we can use to fill copper inton via hole?

Sorry taconics material is not OK as it is a soft feature material which can be randomly “expanded” by filled copper.
