1.有极性或方向的器件在布局上方向不一致，生产人员容易将元件装反；2.

1. The components with polarity or direction are inconsistent in the layout, and the production staff can easily install the components upside down; <br>2. Layout the heavier and taller components on the BOTTOM surface, and there is no glue fixed; 3. The <br>pads on the PCB The spacing is too small; <br>4. The components are too close to the edge of the board, and the force is damaged when the board is divided; <br>5. The components and the V-CUT line are perpendicular to the force and are easily lost;

1. Devices with polarity or direction are inconsistent in layout, and production personnel can easily install components in reverse;<br>2. The heavier, higher component layout is on the BOTTOM surface, and there is no glue fixing;<br>3. The pad spacing on the PCB is too small;<br>4. Components are too close to the edge of the board, when the plate is damaged by force;<br>5. Components and V-CUT line vertically vulnerable to force loss;

1. The devices with polarity or direction are not in the same direction in layout, so it is easy for the production personnel to install the components reversely;<br>2. The heavier and higher components are arranged on the bottom surface without gluing;<br>3. The pad spacing on PCB is too small;<br>4. The component is too close to the edge of the board, and it will be damaged when the board is divided;<br>5. Components perpendicular to V-CUT line are easy to suffer force loss;
