Description

1286457 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to a printing [prior art] circuit board (PCB) and a method of manufacturing the same, in which a consumer electronic product is mass-produced. ESD) certification, due to static electricity generated I, /, hair pressure for printed circuit boards (PCB)

The electronic parts on the board will cause damage, so I 玟 on the printed circuit board (^: Do not take static electricity

The anti-thesis (ESD) measure not only extends the use of the tile in the mouth of the house, but also protects the personal safety of consumers when using electronic products. Please refer to Figure 2, Figure 2 is the cut surface of the printed circuit board (第) as seen in Figure 1 . The printed circuit board (PCB) 1G is formed by stacking a plurality of boards U to achieve electrostatic protection ( ESD), usually using a through hole (and grounded (GND) steel around the printed circuit board (pCB) i〇, to avoid static surge voltage (SUrge) will hit the electronic components 16 in the printed circuit board (pcB) Wearing 4 P-Plates (pcb) i〇, in addition to the hole design 15 provided in the printed circuit board (PCB) in addition to the circuit design, will also follow the printed circuit board (PCB) A plurality of through holes 13 are arranged around the base surface ι〇1, and copper 14 is placed around the hole 13 and the copper 14 is connected to the ground layer. Usually, the width of the hole 13 is 5 〇〇μη! 20 mil) to protect the printed circuit board (PCB) as electrostatic protection (ESD). Since the position error must be taken into consideration when setting the through hole, the outer frame of the printed circuit board (PCB) leaves a clearance 0535- A211 18TWF(N2); A05153; SHERRy 5 1286457 Area 12' in which copper 14 is electroplated on the clearance area 12 and the through holes l3. Typically, the clearance area 12 has a width of 25 0μπι(10πή1), as can be seen from the above, the through hole 13 and the clearance area 12 in the conventional printed circuit board (PCB) are used to achieve the area occupied by electrostatic discharge (ESD), if it is not in the printed circuit board The (PCB) 10 base surface 1〇1 is provided with a through hole 13 and copper plating, and the effect of electrostatic discharge (ESD) can still be achieved, thereby saving the through hole

The area occupied, and since the through hole 13 is not provided, the area saved by the r two area 12' does not have to be left for other circuit designs. SUMMARY OF THE INVENTION In order to improve the above disadvantages, the present invention provides a printed circuit board (PCB) and a method of fabricating the same. The monthly printed circuit board (PCB) includes a plurality of boards, one side and a tributary layer, the plurality of boards are stacked on each other, and the side surrounds the plurality of boards, and the metal layer is disposed on the side on. In an embodiment of the invention, the metal layer is plated on the side and the 5 ohm metal layer is a copper layer. The manufacturing method of the printed circuit board (PCB) of the present invention firstly provides a plurality of laminated plates, wherein the stacked plates comprise one side, and then a plurality of through holes are formed on the plates, and finally the plating is simultaneously performed. Hole and the side. The metal layer % is wound around the side of the printed circuit board (pcB) to provide complete static electricity H to protect various electronic components provided in the printed circuit board (pCB).
