The invention relates to a simple dissecting method for 0603 LED lamp beads, which comprises the following steps: pouring 96-98% of sulfuric acid into a container, putting undissected 0603 lamp beads into a sulfuric acid solution, completely immersing lenses of the lamp beads into the sulfuric acid solution, and taking out the lamp beads after immersing for 10 hours. Strong corrosive solution sulfuric acid is adopted, appropriate solution concentration is selected, a long-time soaking and dissolving mode is selected, and dissection of the 0603 lamp bead is achieved under the condition that a lamp bead chip, an electrode and a core particle structure are not damaged. Moreover, an operator can soak the lamp beads before going off work and take out the lamp beads when going to work next day, and the operator does not need to be on duty. 本申请涉及一种0603led灯珠简易解剖方法，包括如下步骤：将96-98％的硫酸倒入容器内，再将未解剖的0603灯珠放入硫酸溶液内，并使灯珠的透镜完全浸没在硫酸溶液内，浸泡10小时后取出。采用强腐蚀性溶液硫酸，并选取合适的溶液浓度，选择长时间浸泡溶解的方式，在不损伤灯珠芯片、电极、芯粒结构的情况下实现0603灯珠的解剖。并且，操作人员可以在下班前将灯珠浸
