Military and aerospace-grade PCBs are the most rugged, efficient, and reliable printed circuit boards on the market. These pcb army  products are often subjected to high pressure and pressure, which means that they will often require high-temperature substrates, such as high-temperature resistant laminates, copper, or aluminum. Military printed circuit board supplier must produce military PCBs that are resistant to thermally induced oxidation and designed to dissipate heat efficiently at a low weight.
