HDI PCB circuit board first and second order and third order how to distinguish

by:Rocket PCB     2020-08-04
First-order HDI PCB circuit boards, simpler process and process control. Second order began to trouble HDI PCB circuit boards, a counterpoint, a punch and copper plating problem. There are many types of the design of the second order, one is the order stagger position, needs to connect when adjacent layer through a conductor in the middle tier is equivalent to two first-order HDI. The second is that the overlap of two first-order hole, by superimposing way to realize the second order, two first-order processing is similar, but there are many key points to control, which is mentioned above. The third is directly from the outer punch to layer 3 ( Or N - Layer 2) , craft and there are many different front, the difficulty of the punch. For the third order to second-order analogy is. For example: 6 layers PCB in order, second order is according to need of laser drilling for PCB board, namely the HDI board. 6 layers PCB first-order HDI board refers to the blind hole: 1 - 2, 2 - 5, 5 - 6. The 1 - 2, 5 - 6 laser drilling. 6 layers PCB second-order HDI board refers to the blind hole: 1 - 2, 2 - 3, 3 - 4, 4 - 5, 5 - 6. That is 2 times the laser punch. Drill 3 - in the first place 4 buried hole, then pressing 2 - 5, then drill 2 - for the first time 3, 4 - 5 laser hole, then time pressing 1-2 6, then drill 1 - for the second time 2, 5 - 6 laser hole. The last to drill hole. Thus the second order twice pressing after the HDI board, two laser drilling. Second-order HDI board also is divided into: wrong hole second-order HDI board and fold the second-order HDI board, wrong hole second-order HDI board is refers to the blind hole 1 - 2 and 2 - 3 is staggered, and fold the second-order HDI board is refers to the blind hole hole 1 - 2 and 2 - 3 fold together, for example: blind: 1 - 3, 3 - 4, 4 - 6. So on the third order black oil HDI PCB, fourth order & # 8230; … Are the same. A few order number refers to the pressure. First-order PCB, a press fit into, namely can imagine to the most common PCB circuit board. Second order PCB, pressing twice, with eight layer circuit boards, for example, blind hole buried do 2 - first 7 layers of PCB, good pressure, 2 - at this moment 7 hole buried hole is ready, add 1 and 8 layer press, 1 - 8 hole, make the whole board. The third order PCB is more complex than the above, press 3 - first 6 layer, plus 2 and 7 layer, then add 1 to 8 layer, a total of three times in the pressing, general PCB manufacturer can't do it.
