Ceramic Capacitors FAQ

Mounting

Do you take any precautions for setting up the mounting machine when mounting capacitors?

Make sure that the following excessive forces are not applied to the capacitors.

  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 bending 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) Adjust the nozzle pressure within a static load of 1N to 3N during mounting.



  2. Dirt particles and dust accumulated between the suction nozzle and the cylinder inner wall prevent the nozzle from moving smoothly. This imposes greater force upon the chip 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.
