Final answer:
It is FALSE that both quad flatpack and PLCC packages have pins on all four sides; a quad flatpack does, but a PLCC usually does not.
Step-by-step explanation:
It is FALSE that both a quad flatpack and a PLCC (Plastic Leaded Chip Carrier) package have pins on all four sides of the package. A quad flatpack indeed has pins on all four sides. However, a PLCC typically has pins on just two opposing sides or on a J-shaped configuration, which is not equivalent to having pins on all four sides of the package. Knowing the characteristics of various IC packages is important when designing circuits or replacing components in electronic devices.
