请参考图2和图3，图2为本申请所提供的一种具体实施方式中DMD器件固定组件的结构爆破图，图3为图2所示的DMD器件固定组件的剖面示意图。
在本具体实施方式中，一种DMD器件固定组件，包括DMD定位件1、LGA连接器3、FPCB4、压板6、连接件7、第一弹性件8，其中，LGA连接器3用于安装DMD器件10， LGA连接器3与DMD器件10相连接并且LGA连接器3与FPCB4相连接，连接件7依次穿过散热器3的连接孔、压板6的连接孔和FPCB4的连接孔并与DMD定位件1相连接；第一弹性件8一端与压板6相连接，第一弹性件8的另一端与FPCB4相抵接。
与现有技术相比，由于LGA连接器3与FPCB4之间存在弹性连接点，LGA连接器3与DMD器件10之间也存在弹性连接点，采用第一弹性件8与FPCB4进行弹性抵接，如此可以提高LGA连接器3与FPCB4之间连接的可靠性以及LGA连接器3与DMD器件10之间连接的可靠性。利用压板6对第一弹性件8进行安装，并通过连接件7实现压板6的安装，便于安装。
需要说明的是，在本具体实施方式中，压板6的具体厚度在不影响整体的安装高度的前提下根据实际的使用需求进行确定。
此外，为了便于对第一弹性件8进行安装，在本具体实施方式中，压板6设置有安装槽，第一弹性件8安装于安装槽内。如此，通过利用安装槽对第一弹性件8进行安装，可以保证第一弹性件8安装地牢固性。
需要说明的是，在本具体实施方式中，第一弹性件8安装于安装槽内，当然也不排除采用其他的连接方式，如第一弹性件粘结于压板等。

需要说明的是，散热器10的具体型号和尺寸根据实际的使用需求确定。
在进一步的方案中，DMD器件固定组件还包括第二弹性件9，第二弹性件9套设于连接件7的外侧，且第二弹性件9的一端与连接件7相连接，第二弹性件9的另一端与散热器2相抵接。如此，将第二弹性件9套设于连接件7的外侧，第二弹性件9的两端分别与散热器2和连接件7相抵接，且连接件7与DMD定位件1相连接，如此可以提高散热器2与DMD器件10之间连接的可靠性，从而保证散热器2与DMD器件10充分接触，可以提高散热效果。
需要说明的是，在本具体实施方式中，由于第二弹性件9套设于连接件7的外侧，因此在第二弹性件9的弹性作用下，可以保证各个部件之间连接的紧固性，消除由于部件的生产误差而造成的影响，从而可以进一步提高安装的可靠性。
需要进一步说明的是，在本具体实施方式中，第二弹性件9优选的为弹簧，当然，也不排除根据实际的使用需求选择其他弹性件。

需要说明的是，在本具体实施方式中，为了便于连接件7的第一段部伸入至第一孔内，第一孔的孔径不小于第一段部的直径，为了实现连接件7的第一台阶面与第一孔和第二孔形成台阶面相抵接，第二孔的孔径小于第一段部的直径且不小于第二段部的直径。当然，第一孔的孔径和第二孔的孔径根据实际的生产需求进行确定。
此外，在本具体实施方式中，散热器2设置有至少两个连接孔，连接件7分别置于散热器2的安装孔内，如此，压板6的连接孔的设置数目、FPCB4的连接孔的设置数目以及DMD定位件1的连接孔的设置数目与散热器2的连接孔的设置数目相同，且上述三个部件的连接孔与散热器2的连接孔一一相对应设置。如此，可以进一步提高安装的可靠性。

需要说明的是，在本具体实施方式中，安装槽沿着压板6的宽度方向开设，安装槽的槽宽是指安装槽沿着压板6的长度方向延伸的距离，当然，安装槽的具体尺寸根据实际的使用需求进行确定。

还需要说明的是，对安装槽两个部分的再命名只是为了便于进行描述，也不排除采用其他的命名方式。
为了保证散热效果，在本具体实施方式中，DMD器件固定组件还包括导热垫片5，导热垫片5置于散热器2和DMD器件10之间。如此，通过设置导热垫片，可以保证散热器2与DMD器件10充分接触，提高散热效果。
