Infineon is a broad semiconductor supplier that offers a wide range of intelligence products. Many of them are in BGA packages, such as their TC397XX256F300SBDKXUMA2 microcontroller. We’ve had some questions recently on how to solder these products and whether hand soldering is possible for them. What does Infineon have to say?
Hand soldering for BGA package products is not recommended. There’s no real good way to accomplish this. For other methods and recommendations for soldering these devices, Infineon has a handy Board Assembly guide for this product type, here: Infineon Board Assembly Recommendations for BGA Products.
