- (2) Components location on PCB separation 

It is effective to implement the following measures, to reduce stress in separating the board. 

It is best to implement all of the following three measures; however, implement as many measures as possible to reduce stress. 

|Contents of measures|Stress level|
|---|---|
|(1) Turn the mounting direction of the component parallel to the<br>board separation surface.|A > D*1|
|(2)Add slits in the board separationpart.|A > B|
|(3) Keep the mounting position of the component away from the<br>board separation surface.|A > C|
|*1 A > D is valid when stress is added vertically to the perforation as with hand separation.<br>If a cuttingdisc is used, stress will be diagonal to the PCB, therefore A > D is invalid.||



- (3) Mounting components near screw holes 

When a component is mounted near a screw hole, it may be affected by the board deflection that occurs during the tightening of the screw. 

Mount the component in a position as far away from the screw holes as possible. 

## **11.7 Handling of substrate** 

After mounting products on a substrate, do not apply any stress to the product caused by bending or twisting to the substrate when cropping the substrate, inserting and removing a connector from the substrate or tightening screw to the substrate.
