PCB Capability
Sebelum melakukan desain, sebaiknya mempelajari terlebih dahulu spesifikasi PCB yang dapat diproduksi oleh vendor PCB. Tujuannya agar ketika desain sudah selesai dan siap diproduksi bisa segera diproses tanpa perlu melakukan revisi sesuai persyaratan yang diminta oleh bagian manufaktur. Berikut ini spesifikasi PCB yang dapat kami produksi oleh divisi TMN Custom:
