Surface
The surface of the printed circuit board refers to the finish of the connection surfaces in the conductor pattern. The surface protects the copper from oxidation and determines which connecti
PCB connectors
PCB connector usually means one of two types of connectors: board-to-board connector and wire-to-board connector. Board-to-board connectors usually make the unit easier to maintain whe
Laser Direct Imaging
Laser Direct Imaging is a new technology in printed circuit board production. Conductive images can be exposed without going through a film master. The high resolution of the pro
Z-axis milling
Z-axis milling is a variant of milling that does not break through the entire circuit board thickness. The milling machine for this has a depth regulator. Multiple height levels are po
Micro Via
Micro vias are blind vias in HDI circuit boards. They usually have hole diameters <=150µm, pads <=350µm and drilled holes (mostly by laser) with an aspect ratio of almost 1:1.
