Okwu mmalite nke ihe na ọrụ nke akpa mgbochi static maka bọọdụ PCB:

The PCB osisi mgbochi static akpa adopts abụọ oyi akwa ma ọ bụ anọ mejupụtara mejupụtara: (VMPET/CPE ma ọ bụ PET/AL/NY/CPE). The PCB osisi mgbochi static akpa nwere magburu onwe mgbochi static, mgbochi redio ugboro, waterproof vapo penetration, na ọtụtụ ọrụ ndị ọzọ.
