Njengenxalenye eyimfuneko yazo zonke izixhobo zombane, eyona teknoloji idumileyo ehlabathini ifuna epheleleyo PCB uyilo. Nangona kunjalo, inkqubo ngokwayo ngamanye amaxesha ayinanto. Ithambile kwaye intsonkothile, iimpazamo zihlala zisenzeka kwinkqubo yoyilo lwePCB. Ngenxa yokulibaziseka kwemveliso okubangelwa yi-reflow board yesekethe, ezi zilandelayo ziimpazamo ezintathu zePCB eziqhelekileyo ekufuneka ziqatshelwe ukuphepha iimpazamo zokusebenza.

1.) Indlela yokufika

Nangona uninzi lwesoftware yoyilo lwePCB lubandakanya iilayibrari zecandelo loMbane ngokuBanzi, iisimboli zabo zeskim kunye neepateni zokumisa, ezinye iibhodi zesekethe ziya kufuna abayili ukuba bazizobe ngesandla. Ukuba impazamo ingaphantsi kwesiqingatha semilimitha, injineli kufuneka ibe ngqongqo kakhulu ukuqinisekisa isithuba esifanelekileyo phakathi kweepads. Iimpazamo ezenziwe ngeli nqanaba lemveliso ziya kwenza i-welding ibe nzima okanye ingenzeki. Ukuphinda kusetyenzwe kwakhona okuyimfuneko kuya kubangela ukulibaziseka okunendleko enkulu.

2.) Sebenzisa i-vias eyimfama/engcwatyiweyo

Kwiimarike zezixhobo ezijwayele ukusebenzisa i-IoT namhlanje, iimveliso ezincinci kunye ezincinci ziyaqhubeka zisebenzisa impembelelo enkulu. Xa izixhobo ezincinci zifuna ii-PCB ezincinci, iinjineli ezininzi zikhetha ukusebenzisa i-vias eyimfama kwaye ingcwatywe ukunciphisa unyawo lwebhodi yesekethe ukuqhagamshela umaleko wangaphakathi nangaphandle. Nangona umngxuma odlulayo unokunciphisa ngokufanelekileyo indawo yePCB, iyayinciphisa indawo yocingo, kwaye njengoko inani lezongezo lisanda, linokuba nzima, nto leyo eyenza ukuba ezinye iibhodi zibe zibiza kwaye zingenzeki.

3.) Landela ububanzi

Ukuze wenze ubungakanani bebhodi buncinci kwaye buncinci, injongo yenjineli kukwenza umkhondo ube mxinwa ngokusemandleni. Ukumisela ububanzi bomkhondo we-PCB kubandakanya izinto ezininzi eziguquguqukayo, nto leyo eyenza kube nzima, ngoko ke kuyimfuneko ukuqonda ngokupheleleyo ukuba zingaphi ii-milliamps eziya kufuneka. Kwiimeko ezininzi, imfuneko yobubanzi obuncinane ayanelanga. Sincoma ukusebenzisa i-calculator yobubanzi ukumisela ubukhulu obufanelekileyo kunye nokuqinisekisa ukuchaneka koyilo.
