Teach you how to quickly identify PCB board layers [PCB copy board]
Update date：2012-9-15
General customers send pictures over to allow us to assess the cost of the copy board, often we will ask how Laminates, often many customers do not know how to judge, teach you some tips.
Skills I understand the number of PCB layers, common layer of general PCB single panel, dual-panel, 4-layer, 6 layers, 8 shelves, 10 shelves. Usually layers are even engaged in the industry for so long, rarely seen odd PCB board.
Skills, in this light look. The substrate of the PCB itself is insulated, not easy to bend the material produced. Fine line material can be seen on the surface is a copper foil, the original copper foil is to cover the entire PCB board, part of the manufacturing process to be etched to dispose of, the left part of it becomes mesh of fine lines a. These lines are called wire or wiring, and is used to provide a circuit connection of the PCB board parts.
Single-sided and double panel better distinguish between the side of the cable head, the other side does not, then this board is a single panel. The double panel permeability through the light of this surface to see the other side, no line in the middle, and the board on both sides and lines, then proved to be double-sided.
Three techniques, in fact, difficult to judge plywood, this time by virtue of experience, multilayer circuit connection is through the the buried hole and blind hole, most of the motherboard and graphics card using a 4-layer PCB board, also some 6,8 layer, or even 10 layers PCB board. To see how many layers of PCB can be recognized by observing the pilot hole, because the 4-layer board is used on the motherboard and graphics card 1, 4-layer alignment layers otherwise use (ground and power). So, with a two-layer board, the pilot hole penetrated PCB board. If any pilot hole in the front of the PCB board, but the opposite can not find, then it must be a 6/8 laminates.
