specific Embodiment approach 1

[0026] Specific implementation mode one: see figure 1 Describe this embodiment, a method for drawing an adaptive asymmetric pin type chip described in this embodiment, the method includes the following steps:

[0027] Step 1: Draw the rectangular outline of the chip body according to the measured chip body parameters. At this time, the position of the chip body defaults to the initial position; the measured chip body parameters include the dimension X of the rectangular profile in the X-axis direction. body and Y axis dimension Y body ; The length direction of the rectangular profile is the X-axis direction, and the width direction is the Y-axis direction;

[0028] Step 2: Draw the pins on each side of the chip body in turn according to the number of pins on each side of the chip body, the length of the pins, the width of the pins, and the distance between adjacent pins; the length of the pins is equal to The sum of the length of the root of the pin and the length of the foo...

specific Embodiment approach 2

[0032] Specific implementation mode two: see figure 1 This embodiment is described. The difference between this embodiment and the method for drawing an adaptive asymmetric pin-type chip described in the first embodiment is that the method of drawing the rectangular outline of the chip body according to the actual measured chip body parameters The specific process is as follows: according to the parameters of the chip body, the openGL graphics program interface function is used to draw a closed line segment, so as to obtain the rectangular outline of the chip body.

specific Embodiment approach 3

[0033] Specific implementation mode three: see figure 1 and figure 2 Describe this embodiment, the difference between this embodiment and the drawing method of an adaptive asymmetric pin type chip described in the first embodiment is that in the second step, according to the actual measurement of the pins on each side of the chip body The specific process of drawing the pins on each side of the chip body in order of number, pin length, pin width and adjacent pin spacing is as follows:

[0034] Step 21: Define the right, upper, left, and lower sides of the chip body as sides No. 1 to No. 4, and use the openGL graphics program interface function for the pins on sides No. 1 to No. 4 in turn. Step 2 and 4 draw, when the number of pins on any side is greater than or equal to 2, draw the pins on the side from top to bottom;

[0035]Step 2 and 2: judge whether the number of side pins to be drawn is greater than 0, if the judgment result is yes, perform steps 2 and 3, if the judgme...

Abstract

The invention provides an adaptive asymmetric pin type chip drawing method, relates to an asymmetric pin chip drawing method, and solves the problems that the present chip information acquisition system cannot visually observe the accuracy of the acquired chip parameter information. The method comprises the steps that step one: the rectangular contour of a chip body is drawn according to the actually measured parameters of the chip body, wherein the position of the chip body is the initial position by default at the moment; step two: the pins of each edge of the chip body are drawn in turn according to the actually measured number of the pins of each edge of the chip body, the pin length, the pin width and the space between the adjacent pins, wherein the pin length is equal to the sum of the root length of each pin and the foot length of each pin; and step three: the completely drawn chip body and the pins are integrally translated and rotated according to the actually measured chip deviation and the rotating angle so as to complete drawing of the asymmetric pin type chip. The adaptive asymmetric pin type chip drawing method is mainly used for drawing of the asymmetric pins.

Description

technical field [0001] The invention relates to a drawing method of an asymmetric lead chip. Background technique [0002] In the mounting process of the placement machine, the chip is placed on the designated position of the PCB board, and whether the chip is placed in the designated position accurately and the data fed back by the system is particularly important for the placement process of the entire placement machine. The acquisition system collects pictures of the mounted chips on the PCB and solves the calculated chip information. The chip information includes the size of the chip body, the number of chip pins, the length and width of the pins, the pitch of the pins, and the rotation angle of the chip. And the offset in the X and Y directions, etc., the accuracy of these data directly affects the accuracy of placement. [0003] During the placement process, it is necessary to continuously adjust the position of the chip and use a high-precision acquisition system to ...
