Abstract
The utility model relates to an element slot on a circuit board, which comprises the circuit board and has the technical points that two transition holes are drilled on the circuit board; and a connecting groove for communicating the two transition holes is arranged between the two transition holes. The accuracy of the integral element slot disclosed by the utility model is obviously improved. Compared with the accuracy of plus and minus 5mil of the existing common element slot, the accuracy of the element slot disclosed by the utility model is greatly improved, and thus, the requirement on the accuracy of the circuit board can be met under the condition of not improving the production cost, so that the requirement of a client is met. The element slot has a simple manufacturing process.
Description
[technical field]
The utility model relates to the element slot on a kind of circuit board.
[background technology]
Circuit board is widely used in electronic applications, like printed circuit board (PCB), flexible PCB etc.Supply the slot of peripheral element (like CPU) expansion to be called Slot usually on the circuit board.Because the development of electronic horizon, the speed of service of computer is accelerated, and is also higher to the required precision of these slots on the circuit board.The highest tolerance of its precision of the element slot that existing general processing mode processes is ± 5mil, can't reach the demand precision of existing development, thereby can not meet customer need.Improve precision if desired and must adopt accurate more processing instrument, will inevitably improve the production and processing cost like this.
[utility model content]
The purpose of the utility model is the deficiency that overcomes prior art, provides a kind of manufacture craft simple, and production cost is low, the element slot on the high circuit board of precision.
In order to address the above problem, the utility model adopts following technical scheme:
A kind of circuit board component slot comprises circuit board, it is characterized in that: describedly on circuit board, be drilled with two transitional pores, be provided with the link slot that is communicated with two described transitional pores between two described transitional pores.
Aforesaid circuit board component slot is characterized in that: described transitional pore is a circular hole, and described link slot is a square groove.
Aforesaid circuit board component slot is characterized in that: described transitional pore tolerance is ± 3mil.
The beneficial effect of the utility model has: 2 circular holes of subdrilling on circuit board, because the machining accuracy of boring circular hole is higher than the precision of direct processing groove, so the precision of whole element slot will be improved significantly.
[description of drawings]
Fig. 1 is the front view of the utility model;
Fig. 2 is the stereogram of the utility model.
[embodiment]
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Like Fig. 1, shown in Figure 2, the element slot on a kind of circuit board comprises circuit board 1, on circuit board 1, is drilled with two transitional pores 2, and transitional pore 2 hole tolerances are ± 3mil, and mil is a long measure, and 1mil equals 0.001 inch, is equivalent to 0.0254mm.Be provided with the link slot 3 that is communicated with two transitional pores 2 between two transitional pores 2.Transitional pore 2 is a circular hole, and link slot 3 is a square groove.Because the machining accuracy of boring circular hole is higher than the precision of direct processing groove, so that the precision of whole element slot will be improved significantly.Be greatly improved than existing general element slot precision ± 5mil, will under the situation that does not improve production cost, satisfy the circuit board required precision, thereby meet customer need like this.
Claims (3)
1. a circuit board component slot comprises circuit board (1), it is characterized in that: described two transitional pores (2) that on circuit board (1), are drilled with are provided with the link slot (3) that is communicated with two described transitional pores (2) between two described transitional pores (2).
2. circuit board component slot according to claim 1 is characterized in that: described transitional pore (2) is a circular hole, and described link slot (3) is a square groove.
3. circuit board component slot according to claim 1 is characterized in that: described transitional pore (2) tolerance is ± 3mil.
