The rigid type of printed circuit board is the most popular and widely used kind, but the flex type is another type that you could consider adopting after becoming familiar with it, especially because it is now more readily available than ever before because more manufacturers are offering this type. Both connections and complete circuits built using components can be utilized with flex boards. And certainly, depending on the type of film material used, it can withstand the soldering heat much better than stiff ones with high temperatures. It has to do with complexity, the number of materials used, and the processes required in finishing your Flexible PCB. Along with additional stages, rigid PCB manufacturing also involves flex PCB production.
