Njengomyili we-hardware, umsebenzi kukuphuhlisa ii-PCBs ngexesha kunye nohlahlo lwabiwo-mali, kwaye kufuneka zikwazi ukusebenza ngokuqhelekileyo! Kule nqaku, ndiya kuchaza indlela yokuqwalasela imiba yokuvelisa ibhodi yesekethe kuyilo, ukwenzela ukuba iindleko zebhodi yesiphaluka ziphantsi ngaphandle kokuchaphazela ukusebenza. Nceda ukhumbule ukuba ezininzi zezi ndlela zilandelayo zisenokunganeli iimfuno zakho zokwenyani, kodwa ukuba iimeko ziyakuvumela, ziyindlela elungileyo yokunciphisa iindleko.
Gcina onke amacandelo e-surface mount (SMT) kwicala elinye lebhodi yesekethe
Ukuba kukho indawo eyaneleyo ekhoyo, onke amacandelo e-SMT anokubekwa kwicala elinye lebhodi yesekethe. Ngale ndlela, ibhodi yesekethe idinga kuphela ukuba idlule kwinkqubo yokwenziwa kwe-SMT kube kanye. Ukuba kukho amacandelo kumacala omabini ebhodi yesekethe, kufuneka idlule kabini. Ngokuphelisa i-SMT yesibini, ixesha lokuvelisa kunye neendleko zinokugcinwa.
Khetha iindawo ekulula ukuzitshintsha
Xa ukhetha amacandelo, khetha amacandelo ekulula ukuwatshintsha. Nangona oku akuyi kusindisa naziphi na iindleko zokwenyani zokuvelisa, nokuba iindawo ezinokuthi zithathelwe indawo ziphelile, akukho mfuneko yokuyila ngokutsha kunye nohlengahlengiso lwebhodi yesekethe. Njengoko uninzi lweenjineli zisazi, kusemdleni wakhe wonke umntu ukunqanda ukuyila ngokutsha!
Nanga amanye amacebiso okukhetha amalungu atshintshayo alula:
Khetha iinxalenye ezinemilinganiselo eqhelekileyo ukunqanda isidingo sokutshintsha uyilo ngalo lonke ixesha inxalenye iphelelwa lixesha. Ukuba imveliso yokutshintsha inophawu olufanayo, kufuneka utshintshe indawo entsha ukuze uyigqibe!
Phambi kokukhetha izinto, nceda undwendwele iiwebhusayithi zomenzi ukuze ubone ukuba ngaba nawaphi na amacandelo aphawulwe njenge "aphelelwe lixesha" okanye "awacetyiswanga kuyilo olutsha."
Khetha icandelo elinobungakanani be-0402 okanye ngaphezulu
Ukukhetha amacandelo amancinci kugcina indawo yebhodi ebalulekileyo, kodwa olu khetho loyilo lune-drawback. Bafuna ixesha elininzi kunye nomgudu wokubekwa kunye nokubekwa ngokuchanekileyo. Oku kukhokelela kwiindleko eziphezulu zokuvelisa.
Kufana nomtoli otola utolo oluziimitha ezili-10 ububanzi aze alubethe ngaphandle kokunikela ingqalelo kakhulu. Abatoli banokudubula ngokuqhubekayo ngaphandle kokuchitha ixesha elininzi kunye namandla. Nangona kunjalo, ukuba ithagethi yakho iyancipha ukuya kwi-intshi ezi-6 kuphela, ngoko umtoli kufuneka agxininise kwaye achithe ixesha elithile ukuze abethe ithagethi ngokuchanekileyo. Ngoko ke, iinxalenye ezincinci kune-0402 zifuna ixesha elininzi kunye nomgudu wokugqiba ukufakela, oku kuthetha ukuba iindleko ziya kuba phezulu.
Qonda kwaye ulandele imigangatho yemveliso yomenzi
Landela imigangatho enikwe ngumenzi. Uya kugcina ixabiso liphantsi. Iiprojekthi ezintsonkothileyo zihlala zixabisa ngaphezulu ukwenziwa.
Xa uyila iprojekthi, kufuneka ukwazi oku kulandelayo:
Sebenzisa isitaki esisemgangathweni kunye nezixhobo eziqhelekileyo.
Zama ukusebenzisa 2-4 umaleko PCB.
Gcina ubuncinci besithuba somkhondo/isikhewu phakathi kwezithuba ezisemgangathweni.
Kuphephe ukongeza iimfuno ezizodwa kangangoko.
