印刷电路板油墨印刷用定位撑脚
摘要：
本发明公开了一种印刷电路板油墨印刷用定位撑脚，由上支撑和下定位销构成，上支撑为圆台形，下定位销为圆锥形，上支撑的上平面小于下平面，下定位销的锥尖朝下，下定位销自上支撑的下平面向下一体延伸而成，下定位销插于垫板的定位孔中，上支撑的上平面支撑印刷电路板，该定位撑脚在实现印刷电路板的架高及定位的同时，由于上支撑的上平面面积较小，减少了与印刷电路板的接触面积，因此还可避免油墨沾黏。
摘要（英）：

The invention discloses a positioning support leg for printed circuit board ink printing. The positioning support leg is formed by an upper support and a lower positioning pin, wherein the upper support is truncated-cone-shaped, and the lower positioning pin is conical. The upper plane of the upper support is smaller than the lower plane of the upper support. The conical tip of the lower positioning pin faces downwards, the lower positioning pin is formed by downwards integrally extending from the lower plane of the upper support and is inserted into a positioning hole of a base plate, and the upper plane of the upper support supports a printed circuit board. The positioning support leg achieves elevating and positioning of the printed circuit board, reduces the contact area of the support leg and the printed circuit board due to the fact that the area of the upper plane of the upper support is small, and can avoid ink sticking.
