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

Flow soldering can only be used for products with a chip size of 1.6x0.8mm to 3.2x1.6mm.
