Blind Holes FR4 PCB Buried Holes 6 Layer TG170 TG140 for Medical Instrument
Linked Electronics manufactures double sided and multilayer PCB boards for more than 2 decades. With a wide range of potential applications including telecommunications, aviation, automotive and defence, our products are exported around the world, including the Europe USA, Australia, and New Zealand
Blind and buired holes PCB is one of our best sellers, and if you are interested, let's talk about your request with our sales team.
Blind and buried holes are used to connect between layers of a PCB where space is at a premium. A blind hole connects an external layer into one or more inner layers but does not go through the all the layers. A buried holes connects at least two or more inner layers but does not go into any outer layer of the PCB board.
Following Techniques on the PCB boards is within our capabilities.
