(1) Example of a suitable jig

[In the case of Single-side Mounting]

An outline of the board separation jig is shown as follows.

Recommended example: Stress on the component mounting position can be minimized by holding the

portion close to the jig, and bend in the direction towards the side where the capacitors are mounted.

Not recommended example: The risk of cracks occurring in the capacitors increases due to large stress

being applied to the component mounting position, if the portion away from the jig is held and bent in the

direction opposite the side where the capacitors are mounted.

[Hand Separation]

[In the case of Double-sided Mounting]

Since components are mounted on both sides of the board, the risk of cracks occurring can not be avoided with the

above method. Therefore, implement the following measures to prevent stress from being applied to the components.

　 (Measures)

(1) Consider introducing a router type separator.

　

　If it is difficult to introduce a router type separator, implement the following measures.

(Refer to item 1. Mounting Position)

(2) Mount the components parallel to the board separation surface.

(3) When mounting components near the board separation point, add slits in the separation position

near the component.

(4) Keep the mounting position of the components away from the board separation point.

(2) Example of a Disc Separator

An outline of a disc separator is shown as follows. As shown in the Principle of Operation, the top

blade and bottom blade are aligned with the V-grooves on the printed circuit board to separate the board.

In the following case, board deflection stress will be applied and cause cracks in the capacitors.

(1) When the adjustment of the top and bottom blades are misaligned, such as deviating in the top-bottom,

left-right or front-rear directions

(2) The angle of the V groove is too low, depth of the V groove is too shallow, or the V groove is misaligned

top-bottom

IF V groove is too deep, it is possible to brake when you handle and carry it. Carefully design depth of the

V groove with consideration about strength of material of the printed circuit board.
