4. Board Bending Strength for Board Material
(1) Test Method
Solder the chip to the test board. Then bend the board
using the method illustrated below, to measure
capacitance.
(2) Test Samples
GRM21 5C/R7/F5 Characteristics T=0.6mm typical
(3) Acceptance Criteria
Products should be determined to be defective if the
change in capacitance has exceeded the values specified
in Table 4.
