◆Splitting of PCB
◆Mechanical considerations
◆Storage
If capacitors are stored in a high temperature and humidity environment, it might rapidly cause poor solderability due to terminal oxidation and quality loss of taping/
packaging materials. For this reason, capacitors shall be used within 6 months from the time of delivery. If exceeding the above period, please check solderability be-
fore using the capacitors.
1. When PCBs are cleaned after capacitors mounting, Please select the appropriate cleaning solution in accordance with the intended use of the cleaning. （e.g. to
2. Cleaning condition shall be determined after it is verified by using actual cleaning machine that the cleaning process does not affect capacitor's characteristics.
1. The use of inappropriate cleaning solutions can cause foreign substances such as flux residue to adhere to capacitors or deteriorate their outer coating, resulting in
2. Inappropriate cleaning conditions （insufficient or excessive cleaning） may adversely affect the performance of the capacitors.
1. With some type of resins, decomposition gas or chemical reaction vapor may remain inside the resin during the hardening period or while left under normal stor-
2. When a resin's hardening temperature is higher than capacitor's operating temperature, the stresses generated by the excessive heat may lead to damage or
1. When PCBs are split after components mounting, care shall be taken so as not to give any stresses of deflection or twisting to the board.
2. Board separation shall not be done manually, but by using the appropriate devices.
Be careful not to subject capacitors to excessive mechanical shocks.
1. To maintain the solderability of terminal electrodes and to keep packaging materials in good condition, care must be taken to control temperature and humidity in
2. The capacitance values of high dielectric constant capacitors will gradually decrease with the passage of time, So care shall be taken to design circuits . Even if
（1） If ceramic capacitors are dropped onto a floor or a hard surface, they shall not be used.
（2） Please be careful that the mounted components do not come in contact with or bump against other boards or components.
・Recommended conditions
・Ceramic chip capacitors shall be kept where no chlorine or sulfur exists in the air.
