How to Choose the Materials for Low-Temperature PCB Assembly?

Guide to cryogenic PCB design: Balance CTE, Tg, moisture resistance. Material selection (ceramics/polyimides), FPGA alternatives, testing per IPC-6012 for Arctic/space tech.
When to Choose FPGA Over a Microcontroller?

FPGAs excel in parallel processing, real-time tasks, and hardware flexibility; microcontrollers suit simpler, sequential apps. Compare needs vs. development costs.
