3.Maintenance of the Mounting (pick and place) Machine
1. Make sure that the following excessive forces are not applied to the capacitors.
ꢀCheck the mounting in the actual device under actual use conditions ahead of time.
1-1. In mounting the capacitors on the printed circuit board, any bending force against them shall be kept to a minimum to prevent them
from any damage or cracking. Please take into account the following precautions and recommendations for use in your process.
(1) Adjust the lowest position of the pickup nozzle so as not to bend the printed circuit board.

2. Dirt particles and dust accumulated in the suction nozzle and suction mechanism prevent the nozzle from moving smoothly.
This creates excessive force on the capacitor during mounting, causing cracked chips.
Also, the locating claw, when worn out, imposes uneven forces on the chip when positioning, causing cracked chips.
The suction nozzle and the locating claw must be maintained, checked and replaced periodically.
