PCB - Blind and buried holes pcb
Useful pcb when holes diameter, tracks and isolations are very critical
Due to many interconnections requirement, always more frequently it needs to engineer pcbs with blind and buried holes; this technology is for us possible thanks to our drilling machine with spindle with 180k rpm that allow to make accurate micro-drill checked with X-Ray system.
Note:
The printed circuits are also called differently depending on their characteristics, for example:
Single sided
Monolayer and Single side are different ways to identify a printed circuit with a single side or with a single layer of tracks.
Double sided
Double side and bilayer there are different ways to identify a printed circuit with dual sides or with the tracks on both surfaces.
Multilayer
Multilayer MLB are the names that are used to identify multilayer printed circuits with additional layers of internal tracks.
Solder
Solder resist or solder mask is what is called the usually green protective layer that limits the welding to only the pads and also leaves the comb connectors and mechanical contacts uncovered, it is often shortened to solder.
