158 / 221 page  7. Solder Heat Resistance (1) Test Method q Reflow soldering: Apply about 300 µm of solder paste over the alumina substrate. After reflow soldering, remove the chip and check for leaching that may have occurred on the outer electrode. w Flow soldering: After dipping the test sample with a pair of tweezers in wave solder (eutectic solder), check for leaching that may have occurred on the outer electrode. (2) Test samples GRM21: For flow/reflow soldering T=0.6mm (3) Acceptance criteria The starting time of leaching should be defined as the time when the outer electrode has lost 25% of the total edge length of A-B-C-D as illustrated: e Dip soldering: After dipping the test sample with a pair of tweezers in static solder (eutectic solder), check for leaching that may have occurred on the outer electrode. r Flux to be used: An ethanol solution of 25% rosin.
