PCB Inkqubo yokuqhubekeka kwentambo

Kumacala amabini PCB Ibhodi, xa uqhagamshelo luwele, kungasetyenziselwa ukubamba iintambo ezintle nezingalunganga. Kuyilo lwebhodi yesekethe esecaleni elinye, eminye imigca ayinakho ukuqhagamshelwa, ihlala isebenzisa i-jumper wiring, kubaqalayo, ii-jumper wiring zihlala zinobundlongondlongo, zide kwaye zimfutshane, eziya kuzisa ukuphazamiseka kwimveliso. Xa ubeka i-jumper wiring, ukungaphantsi kohlobo, kungcono, zihlala zibeka kuphela i-6mm, 8mm, 10mm ezintathu, ngaphaya kolu luhlu ziya kuzisa ukuphazamiseka kwimveliso. Ukongeza, ezi ndlela zilandelayo zinokusetyenziselwa ukwenza ukuba iingcingo ziwele ukufezekisa indima yokudibanisa i-jumper.

1, Yongeza umgca wokuwela okanye ukumelana no-ohmic. Idityaniswe ngocingo kwibhodi yesekethe ibizwa ngokuba ngumnqamlezo, ibhodi yesekethe efanayo ukuba ubude bomgca womnqamlezo abunifomati buya kuchaphazela ukubonakala, ubude bomgca wokuwela kunye nezinto ezincinci (ezinje ngokuxhathisa) ezingqinelana ngcono. Ukuba ukufakwa kwe-zero ohmic ukumelana kucocekile, ukuze abantu bangaziva ubukho bomnqamlezo.
2. Indlela yokubuyisela endaweni yecandelo. Umzekelo, ukuba umnqamlezo wocingo uqhagamshelwe kuthotho kunye ne-18K or resistor, ukuxhathisa ngoku kutshintshelwe ku-15K ω, kunye ne-3K ω Resistor efakwe kwintambo yomnqamlezo. Ixabiso lilonke lise-18K ω, kwaye ucingo lomnqamlezo lurhoxisiwe.
3, ukuprinta emgceni. Iphaneli enye kunye nomgca wokuprinta onqamlezileyo unokufezekiswa emva komnqamlezo woqhagamshelo, kodwa iindleko zebhodi yokuprinta ziya kuba ngaphezulu.
I-4, i-labyrinth ye-wiring, kwisantya esisezantsi sesekethe yedijithali, ukuze ikwazi ukwenza ucingo kwibhodi enye, inokusebenzisa indlela ye-labyrinth ye-wiring rhoqo kumgama wemingxunya emibini isondele kakhulu phakathi kwe-shuttle edibeneyo. Ngenxa yoxinano lwelayini ephezulu kunye nobubanzi bomgca omxinwa, umlinganiso webhodi yesekethe kufuneka ubemkhulu ngokwentelekiso.
