Multilayer Ceramic Chip Capacitors
Surface Mounting Information
Mounting Design
The chip could crack if the PCB warps during processing after the chip has been soldered.
Recommended chip position on PCB to minimize stress from PCB warpage
(Not recommended)
(Ideal)
Actual Mounting
1) If the position of the vacuum nozzle is too low, a large force may be applied to the chip capacitor during mounting, resulting in cracking.
2) During mounting, set the nozzle pressure to a static load of 100 to 300 gf.
3) To minimize the shock of the vaccum nozzle, provide a support pin on the back of the PCB to minimize PCB flexture.
(Not recommended)
(Ideal)
Crack
Support pin
4) Bottom position of pick up nozzle should be adjusted to the top surface of a substrate which camber is corrected.
5) To reduce the possibility of chipping and cracks, minimize vibration to chips stored in a bulk case.
6) The discharge pressure must be adjusted to the part size. Verify the pressure during setup to avoid fracturing or cracking the chips capacitors.
Resin Mold
1) If a large amount of resin is used for molding the chip, cracks may occur due to contraction stress during curing. To avoid such cracks, use
a low shrinkage resin.
2) The insulation resistance of the chip will degrade due to moisture absorption. Use a low moisture absorption resin.
3) Check carefully that the resin does not generate a decomposition gas or reaction gas during the curing process or during normal storage.
Such gases may crack the chip capacitor or damage the device itself.
