A urip ngrancang bisa nggawe wong aran comfortable.Naturally, desain PCB ngrancang uga luwih mantepake, lan tata letak engineer bisa kurang detour.
Nomer lapisan saka Papan PCB umume ora ditemtokake ing advance, iku wis ngrancang dening Papan lengkap engineer kang, lan nomer total lapisan kasusun saka sawetara lapisan sinyal lan nomer saka lapisan saka sumber daya.
1. Planning saka sumber daya lan nomer stratum
Jumlah lapisan saka sumber daya utamané ditemtokake dening nomer jinis sumber daya, distribusi, kapasitas mbukak, indeks kinerja Papan siji lan biaya setelan board.The siji saka bidang daya perlu kanggo gawe marem loro kondisi: sumber daya ora interlaced.Avoid penting salib-bagean saka lapisan jejer.
Setelan nomer lapisan saka lemah ngirim mbayar manungsa waé kanggo nilai ing ngisor iki: piranti utama kudu bidang lemah relatif lengkap ing pasuryan saka lapisan liya; sinyal penting kayata kacepetan dhuwur, frekuensi dhuwur, jam, sumber daya etc.Main lan bidang lemah kopling nyenyet, ngurangi bidang daya impedansi lan ing.
2. Sinyal nomer lapisan planning
saluran Wiring biasané faktor penting sing nemtokake nomer sinyal layers.It penting kanggo ngerti apa ana BGA jero lan konektor ing Papan, lan ambane saka BGA lan let PIN saka BGA sing tombol kanggo nemtokake nomer BGA line.For conto, BGA saka 1.0mm bisa nglintasi loro garis biasane, 0.8mm BGA salib bolongan mung bisa ngliwati siji baris, lan nomer baris antarane loro garis banget konektor different.The utamané nganggep ambane, kang punika pasangan garis diferensial antarane rong bolongan.
Kapindho, kita kudu nimbang saluran sinyal dhuwur-kacepetan Papan wiring, amarga nalika syarat Processing sinyal-kacepetan dhuwur saka kahanan luwih, kudu nimbang taksih arupi seratan rintisan, let line, faktor kayata bidang referensi, dadi sampeyan perlu kanggo menehi prioritas kanggo saluran wiring cukup. 
Finally, the bottleneck area is planned. After the basic layout is processed, it is necessary to focus on the narrow bottleneck area.Considering the difference line, sensitive signal line, special signal topology, etc., how many lines can be calculated in the bottleneck area, and how many layers can be used to make all the necessary lines pass through this area.
Considering the above two points,basically not appear to go some parts of the line, some people say: pcb design is like a high-rise building building process, the layout of the wiring layer is one of the design drawings, planning well, the wiring naturally It can be done.
Sadurunge miwiti desain PCB, sampeyan kudu ngerti ukuran PCB: iki gumantung ing ukuran produk, lapisan PCB: liyane lapisan, sing liyane Komplek Manufaktur PCB bakal, Sing liyane lapisan PCB wis, liyane larang regane iku bakal Pabrik iku, KingSong PCB specilized ing nyediakake layanan PCB Manufaktur. Kita bisa ndhukung warna layanan Manufaktur papan sirkuit dicithak saka siji lapisan kanggo 36 lapisan kanggo ketemu PCB beda Panjenengan requirements.When rampung desain rancangan, sampeyan njaluk file Gerber, file iki bakal digunakake dening Produsèn PCB , Sanadyan ana akeh perusahaan sing nyedhiyani layanan iki, nanging kita bakal seneng menehi saran King-PCB.COM.
