2. Land Dimensions
2-1. Chip capacitors can be cracked due to the stress
of PCB bending , etc. if the land area is larger than
needed and has an excess amount of solder.
Please refer to the land dimensions in table 1
for flow soldering, table 2 for reflow soldering.
Please confirm the suitable land dimension by
evaluating of the actual SET / PCB.
Table 1 Flow Soldering Method
Dimensions
Part Number
Flow soldering can only be used for products with a chip size of 1.6x0.8mm to 3.2x1.6mm.
