* This is a green soldermask medical device with the 4/4 mil Min. line width and space . For the rigid boards, we can make up to 36 layers for the prototyping and 28 layers for the production with the Min. line width and space being 3/2.5 mil.* This is a impedance control board with its single impedance being 50 Ohm. For the impedance control boards, we will have a impedance testing and generate a report before they are shipped.* The board thickness of the board is 0.093″. We can make upmost 7 mm.
* For the surface finish, we provide not only ENIG but also many other regular surface finish like immersion Tin, HASL LF, OSP and so on.
