Abstract
The invention discloses a method for preventing a sealing bag packaging a printed circuit board from damage. The method comprises the step of arranging the sharp corners of a printed circuit board into a smooth shape. The invention further discloses a printed circuit board of which the corners are smooth. According to the method and the printed circuit board, as the sharp corners of the printed circuit board are arranged into a smooth shape, a sealing bag can be prevented from being scratched by sharp corners, and therefore, the printed circuit board is well protected.
Description
Technical field
The present invention relates to printed-board technology, particularly relate to a kind of method and a kind of printed circuit board (PCB) of the sealing bag breakage that prevents packages printing circuit board.
Background technology
The manner of packing of printed circuit board (PCB) normally packs with antistatic bag, thereby guarantees that airborne moisture and oxygen can not enter packaging bag.The corner of traditional printed circuit board (PCB) is right angle, is just easy to puncture packaging bag, causes airborne moisture and oxygen to enter packaging bag, and the pad on oxidation printed circuit board (PCB), causes failure welding, causes packaging bag can not effectively protect printed circuit board (PCB).
Summary of the invention
Based on this, be necessary to provide a kind of method of the sealing bag breakage that prevents packages printing circuit board.
In addition, also provide a kind of printed circuit board (PCB).
A method that prevents the sealing bag breakage of packages printing circuit board, comprises the steps:
The sharp-pointed corner of described printed circuit board (PCB) is made as to level and smooth shape.
In an embodiment, the described sharp-pointed corner by printed circuit board (PCB) is made as level and smooth shape and is specially therein: be fillet by the sharp-pointed corner polishing of printed circuit board (PCB).
In an embodiment, described printed circuit board (PCB) is rectangle therein, and the described sharp-pointed corner by printed circuit board (PCB) is made as level and smooth shape and is specially: be fillet by four right angle polishings of printed circuit board (PCB).
In an embodiment, the described sharp-pointed corner by printed circuit board (PCB) is made as level and smooth shape and is specially therein: by sheathed the sharp-pointed corner of printed circuit board (PCB) level and smooth shape protective sleeve.
In an embodiment, described printed circuit board (PCB) is rectangle therein, and the described sharp-pointed corner by printed circuit board (PCB) is made as level and smooth shape and is specially: at the sheathed level and smooth shape protective sleeve in four right angles of printed circuit board (PCB).
A kind of printed circuit board (PCB), the corner of described printed circuit board (PCB) is level and smooth shape.
In an embodiment, the outstanding corner of described printed circuit board (PCB) is fillet therein.
In an embodiment, described printed circuit board (PCB) is rectangle therein, and four right angles of described printed circuit board (PCB) are fillet.
Therein in an embodiment, the sheathed level and smooth shape protective sleeve in the sharp-pointed corner of described printed circuit board (PCB).
Therein in an embodiment, the sheathed level and smooth shape protective sleeve in four right angles of described printed circuit board (PCB).
Said method and printed circuit board (PCB), be set to level and smooth shape by the corner of printed circuit board (PCB), can avoid sharp-pointed corner to scratch sealing bag, thereby also printed circuit board (PCB) played to good protective effect.
Accompanying drawing explanation
Fig. 1 is the printed circuit board (PCB) schematic diagram of an embodiment;
Fig. 2 is the printed circuit board (PCB) schematic diagram of another embodiment.
Embodiment
The method of the sealing bag breakage that prevents packages printing circuit board of one embodiment, comprises the steps: the sharp-pointed corner of described printed circuit board (PCB) to be made as level and smooth shape.Smoothly that the printed circuit board (PCB) that corner is level and smooth shape can not scratch sealing bag for sharp-pointed.Level and smooth shape can be various shape, such as circular arc, waveform etc.
In a preferred embodiment, when printed circuit board (PCB) is rectangle, it is specifically fillet by four right angle polishings of printed circuit board (PCB) that the sharp-pointed corner of described printed circuit board (PCB) is made as to level and smooth shape.Four jiaos be fillet printed circuit board (PCB) as shown in Figure 1.Polishing is that fillet is relatively simple, and anti-effect of scratching is also fine.In the time that printed circuit board (PCB) is other shapes, can, according to the mode of previous embodiment, be also fillet by the sharp-pointed corner polishing of printed circuit board (PCB).This just makes the outstanding corner of printed circuit board (PCB) be fillet.
In another preferred embodiment, when printed circuit board (PCB) is rectangle, at the sheathed level and smooth shape protective sleeve in four right angles of printed circuit board (PCB).As shown in Figure 2, at the sheathed level and smooth shape protective sleeve 200 in four angles of the plate body 100 of printed circuit board (PCB), the outer rim of protective sleeve 200 is more level and smooth, can be circular arc, waveform etc.The protective sleeve that preferred level and smooth shape protective sleeve 200 is fillet.In the time that printed circuit board (PCB) is other shapes, also can be according to the mode of previous embodiment, at the sheathed level and smooth shape protective sleeve in the sharp-pointed corner of printed circuit board (PCB).
By being fillet or the protective sleeve that level and smooth shape is set by the sharp-pointed corner polishing of printed circuit board (PCB), can avoid sharp-pointed corner to scratch sealing bag, thereby also printed circuit board (PCB) played to good protective effect.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
