History for many years；Its design is mainly layout design；Major advantage using circuit board is to greatly reduce wiring and assembling
Mistake, improve the gentle productive labor rate of Automated water.According to the wiring board number of plies can be divided into single sided board, dual platen, four laminates,
Six laminates and other multilayer circuit boards.Dual platen is intermediate one layer of medium, and two sides is all wiring layer.Multi-layer board is exactly laminates
Line layer is dielectric layer between every two layers, and dielectric layer can be made thin, multilayer circuit board at least three-layer routing layer, wherein two
Layer is in outer surface, and remaining one layer is combined in insulation board, and the electrical connection between them is typically by circuit board horizontal stroke
What the plated-through-hole on section was realized.Since circuit integration density is high and internal layer is closed, for the heat dissipation of plated-through-hole extremely
Close important, there are two types of existing radiating modes, water cooling and air-cooled, but both are radiated from outside, for thicker
For multilayer circuit board, internal temperature radiates not in time, and to plated-through-hole, thermal damage is larger, reduces the service life, therefore we carry
Go out a kind of PBC circuit boards.
