PCB News - Cutting process of circuit board factory

Cutting is the cutting of large-size plates to the size required for actual production. It is a very important beginning in our circuit board production process. Our circuit board factory is becoming more concentrated, and circuit board production has become a part of the entire industry. Keep up Let's take a look at the pace of the editor.

The cutting of the circuit board factory is to cut the large-size copper clad laminate raw material (sheet) into small-size (panel) production boards, and perform rounding and edge grinding to prevent the sharp corners and burrs of the board during the processing. Scratch the printed circuit board or the operator, and then bake the board to eliminate the internal stress in the copper clad laminate to reduce the deformation of the board in the subsequent processing. Our Shenzhen circuit board factories use the most when cutting Raw materials for copper plates.

So what is the legendary copper clad laminate in the circuit board factory where the circuit board is concentrated? The copper clad laminate is a material made by impregnating a strengthening material with resin, covering one or both sides with copper foil, and pressing it together. Mainly play the role of conduction, insulation and support. The English name Copper Clad Uminate, abbreviated as CCt, is a full-blown copper clad laminate, or copper clad laminate for short. It can be covered with copper foil on one or both sides, called single-sided copper clad laminate or double-sided clad laminate.

Our circuit board factory will use a cutting and cutting machine when cutting. Each board will be cut by the machine and appear flat in front of everyone. After the cutting edge of the cutting board is blunt, it can be removed for grinding and then restarted. use. The life of the cutter is related to the type of cutting and turning. It is undoubtedly the former when cutting glass fiber cloth-containing copper clad laminates and thick copper clad copper clad laminates compared to cutting paper-based clad laminates and thin copper clad copper clad laminates. The cutter life is shorter. In addition to the thickness of the board, the blade gap of the cutting machine is also related to the material of the board substrate.

The operators of our circuit board factory are very dedicated. Every time the cutting machine is changed, the cumulative cutting board area must be recorded from 0. When the specified area is reached, the cutting knife is replaced; in addition, if there is When there is obvious lifting or severe burrs, the cutting knife should also be checked or replaced to prevent errors from causing problems with the board.
