Description

一种屏蔽框钢网开口方法、装置、电子设备及存储介质 技术领域
本发明属于印制电路板技术领域，具体涉及一种屏蔽框钢网开口方法、装置、电子设备及存储介质。

电子制造业的快速发展使得高集成、高密度的电子产品应用越来越广泛，因此也引发了很多电磁干扰的问题，为了解决此类问题因此需要在硬件设计中使用屏蔽罩来防止对外辐射和被辐射干扰。屏蔽罩是用来屏蔽电子信号的工具。作用就是屏蔽外界电磁波对内部电路的影响和内部产生的电磁波向外辐射。

具体实施方式
下面结合具体实施例对本发明做进一步详细的描述，但本发明的实施方式不限于此。
实施例一
请参见图1和图2，图1是本发明实施例提供的一种屏蔽框钢网开口方法的流程示意图，图2是本发明实施例提供的另一种屏蔽框钢网开口方法的流程示意图，本实施例提供了一种屏蔽框钢网开口方法，该屏蔽框钢网开口方法可以包括步骤1至步骤3，其中：
步骤1、获取第一屏蔽框钢网开口，第一屏蔽框钢网开口在第一预设方向上与水平方向或垂直方向平行。
具体地，第一屏蔽框钢网开口的尺寸应能满足焊接的质量，且第一屏蔽框钢网开口在第一预设方向上与水平方向或垂直方向平行，第一预设方向即为第一屏蔽框钢网开口在某一方向上与水平方向或垂直方向平行的方向，例如请参见图3，当PCB板为矩形时，只要保证第一屏蔽框钢网开口与PCB板平行即可，因此当PCB板为矩形时，仅需保证PCB板和第一屏蔽框钢网开口某条边平行即可，而当PCB板为其它形状，例如圆形时，只要保证第一屏蔽框钢网开口与水平方向或垂直方向平行即可，其可以根据具体情况进行设计，在此不再赘述。
在一个具体实施例中，步骤1可以具体包括步骤1.1至步骤1.3，其中：
步骤1.1、获取第一初始屏蔽框钢网开口。
具体地，从PCB设计数据中获取出所有焊盘信息，包含器件坐标、外框、图像信息等，并将屏蔽框焊盘信息从PCB设计数据中取出，以得到第一初始 屏蔽框钢网开口，第一初始屏蔽框钢网开口即初始设计的PCB设计数据中的屏蔽框的钢网开口数据。
步骤1.2、判断第一初始屏蔽框钢网开口在第一预设方向上与水平方向或垂直方向是否平行，若不平行，则将第一初始屏蔽框钢网开口沿第一方向旋转角度G，得到第二初始屏蔽框钢网开口，且第二初始屏蔽框钢网开口在第一预设方向上与水平方向或垂直方向平行，若平行，则第一初始屏蔽框钢网开口即为第二初始屏蔽框钢网开口。
具体地，在实际使用时，第一初始屏蔽框钢网开口可能与水平方向或垂直方向没有处于平行状态，即第一初始屏蔽框钢网开口呈倾斜状态，与水平方向或垂直方向平行存在一定的角度，此时则需要沿某一方向(即第一方向)对第一初始屏蔽框钢网开口进行旋转，旋转的角度为G，旋转角度G后的第一初始屏蔽框钢网开口应与水平方向或垂直方向平行，旋转角度G后的第一初始屏蔽框钢网开口即为第二初始屏蔽框钢网开口，其中，第一方向为顺时针方向或者逆时针方向。另外，当第一初始屏蔽框钢网开口与水平方向或垂直方向平行时，则不需要对第一初始屏蔽框钢网开口进行旋转处理，此时，第一初始屏蔽框钢网开口即为第二初始屏蔽框钢网开口。
步骤1.3、根据第二初始屏蔽框钢网开口得到第一屏蔽框钢网开口。
具体地，当第二初始屏蔽框钢网开口的尺寸能够满足焊接的质量，能保证焊接牢固时，则不需要对第二初始屏蔽框钢网开口进行处理，此时可以直接将第二初始屏蔽框钢网开口作为第一屏蔽框钢网开口，但是一般情况下，因初始设计的屏蔽框钢网开口的尺寸不能满足焊接质量的要求，因此需要对初始设计的屏蔽框钢网开口进行外扩处理，即：
在第二预设方向上，将第二初始屏蔽框钢网开口沿内、外分别外扩预 设距离，得到第一屏蔽框钢网开口。
也就是说，在第二预设方向上将第二初始屏蔽框钢网开口向内外扩预设距离T，同时向外外扩预设距离T，由此可以在第二预设方向上加宽屏蔽框钢网开口的尺寸，这样可以保证锡膏量，从而使得焊接牢固，另外可以保证爬锡高度，从而提高焊接质量，其中，请参见图3，第二预设方向为宽度方向，对于屏蔽框钢网开口的上下两条边框，其宽度方向为图3中的宽度方向1，对于屏蔽框钢网开口的左右两条边框，其宽度方向为图3中的宽度方向2。
进一步地，为了保证焊接质量，预设距离T的取值范围为：0.1mm≤T≤0.3mm。
步骤2、根据距拐角点适配距离和第一屏蔽框钢网开口的夹角拐角对第一屏蔽框钢网开口的夹角拐角进行架桥处理，得到第二屏蔽框钢网开口。
具体地，当屏蔽框钢网开口中存在夹角拐角时，可能存在刮刀印锡后，脱模时锡膏产生毛刺或脱锡困难的问题，因此为了防止上述问题，本实施例以距拐角点适配距离作为分界点，对第一屏蔽框钢网开口的夹角拐角进行架桥处理，从而达到防止刮刀印锡后，脱模时锡膏产生毛刺或脱锡困难的问题出现。其中，架桥就是将连续的地方分割开。另外，夹角拐角例如为图3的直角拐角，也可以为其它角度的夹角，其与具体设计有关，在此不再。
在一个具体实施例中，步骤2可以具体包括步骤2.1至步骤2.3，其中：
步骤2.1、获取第一屏蔽框钢网开口的夹角拐角，例如图4至图7中的点b分别为处于左上角、右上角、右下角和左下角的夹角拐角处的点。
步骤2.2、根据第一屏蔽框钢网开口的夹角拐角的位置和相邻两点的位 置得到第一距离和第二距离。
具体地，第一距离和第二距离为处于夹角拐角的点与相邻两个点之间的距离，例如请参见图4，当夹角拐角为左上角时，获取到a点坐标(x1，y1)，b点坐标(x2，y2)，c点坐标(x3，y3)，那么第一距离A＝|y1-y2|，第二距离B＝|x3-x2|；例如请参见图5，当夹角拐角为右上角时，获取到a点坐标(x1，y1)，b点坐标(x2，y2)，c点坐标(x3，y3)，那么第一距离A＝|x1-x2|，第二距离B＝|y3-y2|；例如请参见图6，当夹角拐角为右下角时，获取到a点坐标(x1，y1)，b点坐标(x2，y2)，c点坐标(x3，y3)，那么第一距离A＝|y1-y2|，第二距离B＝|x3-x2|；例如请参见图7，当夹角拐角为左下角时，获取到a点坐标(x1，y1)，b点坐标(x2，y2)，c点坐标(x3，y3)，那么第一距离A＝|x1-x2|，第二距离B＝|y3-y2|。
步骤2.3、根据第一距离、第二距离和距拐角点适配距离的关系对第一屏蔽框钢网开口的夹角拐角进行架桥处理，得到第二屏蔽框钢网开口。
具体地，本实施例基于第一距离、第二距离和距拐角点适配距离的关系，对第一屏蔽框钢网开口中的每个夹角拐角进行架桥处理，所有夹角拐角均处理完毕后，便可以得到第二屏蔽框钢网开口。在本实施例中，将第一距离记为A，第二距离记为B，距拐角点适配距离记为U。
在一个具体实施例中，步骤2.3可以包括如下四种情况：
情况1：当第一距离、第二距离均小于或者等于距拐角点适配距离时，则在第一距离和第二距离中的最短距离侧的夹角拐角处进行架桥处理，其中，最短距离为第一距离和第二距离中值较小的那一个，则当第一距离小于第二距离时，在靠近第一距离侧架桥，当第一距离大于第二距离时，在靠近第二距离侧架桥，即桥的一边处于夹角拐角处，桥的另一边位于最短 距离侧
也就是说，当A≤U，B≤U,则在靠近更短的(min{A，B})那侧架桥，架桥宽度为p。例如，请参见图8，如B<A，则在靠近B的那侧架桥，即桥的一边处于拐角处，另一边靠近B。
另外，请参见图9，架桥角度的设计方法为：外轮廓拐角点和内轮廓拐角点的连线与水平方向形成的角度，即架桥角度的计算方式为：arctan(|y2-y6|/|x2-x6|)。
情况2：当第一距离小于或者等于距拐角点适配距离、且第二距离大于距拐角点适配距离时，则在第二距离侧的夹角拐角处进行架桥处理，即桥的一边处于夹角拐角处，桥的另一边位于第二距离侧。
也就是说，请参见图8，当A≤U，B＞U，架桥在夹角拐角偏B处，架桥宽度为P。
情况3：当第一距离大于距拐角点适配距离、且第二距离小于或者等于距拐角点适配距离时，则在第一距离侧的夹角拐角处进行架桥处理，即桥的一边处于夹角拐角处，桥的另一边位于第一距离侧。
也就是说，请参见图10，当A＞U，B≤U，架桥在夹角拐角偏A处，架桥宽度为P。
情况4：当第一距离和第二距离均大于距拐角点适配距离时，则在夹角拐角的中间处进行架桥处理，即桥的一边位于第一距离侧，桥的另一边位于第二距离侧，且桥的中心线处于夹角拐角处。
也就是说，请参见图11，当A＞U，B＞U，架桥拐角处正中间，架桥宽度P。
在本实施例中，经过大量的数据测试证明，距拐角点适配距离U的取值 范围为：2mm≤U≤4mm时，可以更好的防止刮刀印锡后，脱模时锡膏产生毛刺或脱锡困难的问题出现。
步骤3、根据第二屏蔽框钢网开口中每段钢网开口的预设长度、适配连续开口长度值和最小开口宽度值对第二屏蔽框钢网开口的钢网开口进行处理，得到第三屏蔽框钢网开口。
具体地，本实施例的第二屏蔽框钢网开口由若干段小的钢网开口组成，因此对于第二屏蔽框钢网开口中的每段钢网开口，本实施例基于钢网开口的预设长度、适配连续开口长度值和最小开口宽度值对每段钢网开口进行处理，当所有钢网开口均处理完毕后，便可以得到第三屏蔽框钢网开口。
在本实施例中，从步骤2更新完成的第二屏蔽框钢网开口中取出屏蔽框中闭合的段，一个闭合的段即为一段小的钢网开口，可以沿顺时针读取每个闭合的段，如从图3的左上角开始，获取用于计算钢网开口的预设长度的钢网开口的两个端点，由此便可以通过两个端点计算钢网开口的预设长度，请参见图12，如钢网开口的两个端点的坐标分别为d(x4，y4)、e(x5，y5)，那么钢网开口的预设长度L＝|x5-x4|，其中，请参见图3，钢网开口的预设长度为其长度方向的长度，对于屏蔽框钢网开口的上下两条边框，其长度方向为图3中的长度方向1，对于屏蔽框钢网开口的左右两条边框，其长度方向为图3中的长度方向2。在本实施例中，适配连续开口长度值记为K，试验得出每隔间距K，架桥宽度为P，可以使钢网张力达到40N/CM以上，一般适配连续开口长度值K会根据钢网的开口比、宽厚比等确定，优选地，适配连续开口长度值K的取值范围为：5mm≤K≤9mm，最小开口宽度值为钢网开口的最小宽度值，最小开口宽度值记为R，其中，钢网开口的宽度和钢网的厚度之比为宽厚比，如要求宽厚比小于1.5，由此便可以确定最小开口宽度 值，而最小开口宽度值可以根据的设计方案确定，本实施例对此不做具体限定。
在一个具体实施例中，步骤3可以包括如下四种情况：
情况1：当钢网开口的预设长度小于或者等于最小开口宽度值时，则去除钢网开口。
具体地，请参见图12，当L≤R,则去除这个钢网开口。
情况2：当钢网开口的预设长度大于最小开口宽度值、且小于或者等于适配连续开口长度值时，则钢网开口保持不变。
具体地，请参见图13，当R＜L≤K，则钢网开口保持不变。
情况3：当钢网开口的预设长度大于适配连续开口长度值、且小于预设倍数的适配连续开口长度值时，则在钢网开口的第一预设位置处进行架桥处理。
进一步地，在水平方向上，第一预设位置为(x4+L/2-P/2，y4)，在垂直方向上第一预设位置为(x4，y4-L/2+P/2)，其中(x4、y4)为钢网开口的上拐角坐标，上拐角即为处于钢网开口上端的拐角，例如，请参见图14，(x4、y4)为拐角处点d的坐标。
优选地，预设倍数为1.5。
具体地，对于处于屏蔽框钢网开口的上下两条边框的钢网开口，请参见图14，当K＜L≤1.5K，设左上角d点坐标为(x4，y4)，右上角e(x5，y5)，则L＝|x5-x4|，因此在水平方向上在(x4+L/2-P/2，y4)处架宽度为P的桥；对于处于屏蔽框钢网开口的左右两条边框的钢网开口，当K＜L≤1.5K，设右上角d点坐标为(x4，y4)，右下角e点坐标为(x5，y5)，则L＝|y5-y4|，因此在垂直方向上从(x4，y4-L/2+P/2)处架宽度为P的桥。
情况4：当钢网开口的预设长度大于预设倍数的适配连续开口长度值时，则在所钢网开口的第二预设位置处行架桥处理，直至第二屏蔽框钢网开口的所有钢网开口均满足预设条件，并按照预设条件处理完其对一个的钢网开口后，才完成对屏蔽框钢网开口的处理，其中，预设条件为步骤3中的情况1、情况2和情况3中的任意一种情况。
进一步地，在水平方向上，第二预设位置为(x4+K，y4)，在垂直方向上，第二预设位置为(x4，y4-K)，其中(x4、y4)为钢网开口的上拐角坐标，例如，请参见图15，(x4、y4)为拐角处点d的坐标。
具体地，对于处于屏蔽框钢网开口的上下两条边框的钢网开口，请参见图15，当L＞1.5K,设左上角d点坐标为(x4，y4)，则沿水平方向从(x4+K，y4)处架宽度为P的桥，对于该钢网开口剩余部分的部分继续按照上述方式进行判断；对于处于屏蔽框钢网开口的左右两条边框的钢网开口，当L＞1.5K,设左上角d点坐标为(x4，y4)，则沿垂直方向从(x4，y4-K)处架宽度为P的桥，对于该钢网开口剩余部分的部分继续按照上述方式进行判断，按照上述方式对每个钢网开口处理，直至每个钢网开口均满足预设条件为止。
在一个具体实施例中，因为某些初始设计的屏蔽框钢网开口与水平方向或垂直方向不平行，因此会将初始设计的屏蔽框钢网开口沿第一方向旋转角度G，因此再完成上述步骤后，还需要将旋转的屏蔽框钢网开口恢复至初始位置，因此在得到第三屏蔽框钢网开口之后，还包括：
将第三屏蔽框钢网开口沿第二方向旋转角度G，以得到旋转后的第三屏蔽框钢网开口，其中，第一方向和第二方向互逆。
在一个具体实施例中，在得到第三屏蔽框钢网开口之后或者再将第三屏蔽框钢网开口沿第二方向旋转角度G之后，还包括：
判断第三屏蔽框钢网开口中的钢网开口是否满足安全距离，若不满足，则去除不满足安全距离的钢网开口。
具体地，将更新好的第三屏蔽框钢网开口坐标信息与器件外框等坐标信息进行间距审查，应保证与其他器件、通孔、金边、镀金面，单独焊盘等保持J的安全距离；与测试点应保持M的安全距离，若更新好的第三屏蔽框钢网开口坐标信息不符合上述安全距离的要求，则将不满足安全距离部分的钢网开口去除，以生成最终的屏蔽框钢网开口，例如图16，为图3通过本实施例的屏蔽框钢网开口方法所最终得到的屏蔽框钢网开口设计方案，其中，安全距离J例如为0.2mm，安全距离M为0.4mm。
若夹角不是直角时，则以当前处理钢网开口为个体，开始旋转G1，使其与水平方向或垂直方向平行，再进行夹角拐角架桥处理,处理完成之后做归位处理。
本发明确定了一种新的屏蔽框钢网开口方法，该方法首先获取了一与水平方向或垂直方向平行的第一屏蔽框钢网开口，然后基于距拐角点适配距离和第一屏蔽框钢网开口的夹角拐角的关系，对第一屏蔽框钢网开口的夹角拐角进行架桥处理，之后再基于每段钢网开口的预设长度、适配连续开口长度值和最小开口宽度值的关系对每个钢网开口进行处理，由此可以使得最终生成的钢网开口方案的应力分布合理，脱锡方便，而且可以有效的避免屏蔽框与器件碰撞的隐患，避免了人为干预环节，减少了生产的出错率，降低了企业的生产成本，提升了产品的竞争力。
实施例二
为了更好地理解本发明提供的屏蔽框钢网开口方法，在上述实施例的基础上还提供一种具体地屏蔽框钢网开口方法，该屏蔽框钢网开口方法包 括：
S1、从PCB设计数据中获取出所有焊盘信息，包含器件坐标、外框、图像信息等。将屏蔽框焊盘信息取出，由于本实例中的屏蔽框焊盘处于水平状态所以不需要进行归零化处理，或归零化旋转角度为0度，将处理好的屏蔽框焊盘信息设置为预设屏蔽框钢网开口。
S2、在宽度方向上，将获取到的预设屏蔽框钢网开口沿内外分别外扩0.1mm，以更新预设屏蔽框钢网开口。
S3、从S2更新后的预设屏蔽框钢网开口中按照顺时针方向，从左上方开始取出屏蔽框中内夹角为夹角的坐标，按照上述架桥规则依次架桥为：
取屏蔽框钢网外框左上角点的坐标为(75.34，83.42)，对应的内轮廓拐角坐标为(72.34，80.42)，该左上角点对应的逆时针方向连续段的坐标点为(75.34，81.7)，该左上角点对应的顺时针方向连续段的坐标点为(79.72，83.42)，距拐角点适配距离记为U取3.5，那么A＝|83.34-81.7|＝1.72mm，则A≤3.5mm；B＝|79.72-75.34|＝4.38mm，B>3.5mm，所以在偏水平方向架设角度为arctan(|83.42-80.42|/|75.34-72.34|)＝45度的过桥，其宽度为0.5mm；
取屏蔽框钢网外框右上角点的坐标为(126.4，83.42)，对应的内轮廓拐角点坐标为(123.4，80.42)，该右上角点对应的逆时针方向连续段的坐标点为(121.9，83.42)，该右上角点对应的顺时针方向连续段的坐标点为(126.4，40.6，那么A＝|126.6-121.9|＝4.5mm，A>3.5mm；B＝|40.6-83.42|＝42.82mm，B>3.5mm，因此在夹角拐点中间架设角度为arctan(|126.4-123.4|/|83.42-80.42|)＝45度的过桥，其宽度为0.5mm；
取屏蔽框钢网外框右下角点的坐标为(126.4，18)，对应的内轮廓拐角点坐标为(123.4，15)，该右下角点对应的逆时针方向连续段的坐标点为 (126.4，36.8)，该右下角点对应的顺时针方向连续段的坐标点为(75.34，18)，那么A＝|18-36.8|＝18.8mm，A>3.5mm；B＝|75.34-36.8|＝51.06mm，B>3.5mm，因此在夹角点中间架设角度为arctan(|126.4-123.4|/|18-15|)＝45度的过桥，其宽度为0.5mm；
取屏蔽框钢网外框左下角点的坐标为(75.34，18)，对应的内轮廓拐角点坐标为(72.34，15)，该左下角点对应的逆时针方向连续段的坐标点为(126.4，18)，该左下角点对应的顺时针方向连续段的坐标点为(75.34，80.3)，那么A＝|75.34-126.4|＝51.06mm，A>3.5mm；B＝|80.3-18|＝62.3mm，B>3.5mm，因此在夹角点中间架设角度为arctan(|75.34-72.34|/|18-15|)＝45度的过桥，其宽度为0.5mm。
S4、沿顺时针方向从S3更新完成的屏蔽框钢网开口中取出屏蔽框中闭合的段，从左上角第一个钢网开口开始，获取每个钢网开口的预设长度，当预设长度为3mm时，由于1mm<3mm<7mm，所以本钢网开口不做改变，其中1mm为最小开口宽度值，7mm为适配连续开口长度值，依次获取其他剩余闭合的段，按照下面的规则处理每个钢网开口，即：
①当L≤1mm,去除这个钢网开口；
②当1mm＜L≤7mm，钢网开口不变(此处K＝7)；
③当7mm＜L≤10.5mm，在中心处架宽度为1.2mm的桥；
④当L＞10.5mm，每隔距离为7mm处架一个宽为1.2mm的桥，将架桥分割后的部分继续按照上述方法进行处理，当满足①、②或③条件时，按照①、②或③方式处理完之后，继续按照上述方式处理下一段钢网开口。
S5、按照S4的方式完成分割架桥后将钢网开口反向旋转角度0度，完成 角度补充处理。
S6、将S4更新好的钢网开口坐标信息与器件外框等坐标信息进行间距审查，应保证与其他器件、通孔、金边、镀金面，单独焊盘等保持0.2mm的安全距离；与测试点应保持0.4mm安全距离；经过检测本次生成的钢网开口符合距离检查标准。
