CHAPTER 3 SOLDERING CONDITIONS


3.1 Solderability
3.1.4 Solderability following high-temperature storage

Figure 3-1-6 shows the solderability when high-temperature baking (150°C) is performed for up to 500 hours.
These results indicate stable solderability with the wet time remaining unchanged even after 500 hours.
