I. Iphedi liyagqagqana
1. Ukugqagqana kwamaphedi (ngaphezu kwamaphedi okunamathisela angaphezulu) kusho ukuthi ukunqwabelana kwezimbobo, enqubweni yokubhoboza kuzoholela embotsheni ephukile ngenxa yokubhoboza okuningi endaweni eyodwa, okuholela ekulimaleni kwembobo.
2. Ibhodi le-Multilayer emigodini emibili iyagqagqana, njengembobo yediski yokuhlukanisa, enye imbobo yediski yokuxhuma (ama-flower pads), ukuze ngemva kokudweba ukusebenza okungalungile kwediski yokuhlukanisa, okuholela ekulahlekeni.
II.Ukuhlukunyezwa kwesendlalelo sezithombe
1. Kwezinye ihluzo ungqimba ukwenza ezinye uxhumano engenamsebenzi, ekuqaleni ezine ungqimba ibhodi kodwa yakhelwe izingqimba ezingaphezu kwezinhlanu zomugqa, ukuze imbangela yokungaqondi.
2. Idizayina ukonga isikhathi, isofthiwe ye-Protel, isibonelo, kuzo zonke izingqimba zomugqa onesendlalelo Sebhodi ozodwetshwa, kanye nosendlalelo Sebhodi ukuze klwelwe umugqa welebula, ukuze uma idatha yomdwebo wokukhanya, ngenxa yokuthi ungqimba Lwebhodi alukhethiwe, iphuthelwe ukuxhumeka nokuphuka, noma izofinyezwa ngenxa yokukhethwa kwesendlalelo Sebhodi yomugqa welebula, ngakho-ke idizayini yokugcina ubuqotho bongqimba lwezithombe futhi icacile.
3. Ngokumelene nomklamo ovamile, njengokuklanywa kwengxenye yendawo engaphansi kwesendlalelo se-Bottom, i-welding surface design Phezulu, okubangela ukuphazamiseka.
III.Umlingiswa wokubekwa kwesiphithiphithi
1. Ikhava yohlamvu pads SMD solder lug, ebhodini ephrintiwe ngokusebenzisa ukuhlolwa kanye ingxenye welding ukuphazamiseka.
2. Idizayini yomlingiswa incane kakhulu, idala ubunzima kuhleloumshini wokuphrinta isikriniukuphrinta, kukhulu kakhulu ukwenza izinhlamvu zidlulelane, kube nzima ukuzihlukanisa.
IV.Izilungiselelo zokuvula iphedi elinohlangothi olulodwa
1. Amaphedi anohlangothi olulodwa ngokuvamile awabhojwa, uma imbobo idinga ukumakwa, indawo yayo yokuvula kufanele yakhelwe ku-zero.Uma inani lenzelwe ukuthi lapho idatha yokumba ikhiqizwa, lesi sikhundla sivela kuzixhumanisi zembobo, kanye nenkinga.
2. Amaphedi anohlangothi olulodwa njengokubhola kufanele amakwe ngokukhethekile.
V. Ngebhulokhi yokugcwalisa ukudweba amaphedi
Ngomdwebo womdwebo we-filler block ekwakhiweni komugqa ungadlula isheke le-DRC, kodwa ukucubungula akunakwenzeka, ngakho-ke i-pad yeklasi ayikwazi ukukhiqiza ngokuqondile idatha yokumelana ne-solder, lapho ku-solder ukumelana, indawo ye-filler block izombozwa i-solder imelana, okuholela ebunzimeni bokunamathisela idivayisi.
VI.Isendlalelo somhlaba kagesi sibuye sibe yiphedi lembali futhi sixhunywe kulayini
Ngenxa yokuthi ukunikezwa kwamandla okuklanyelwe njengendlela ye-flower pad, ungqimba lomhlabathi kanye nesithombe sangempela ebhodini eliphrintiwe liphambene, yonke imigqa yokuxhuma iyimigqa engayodwa, okumele umklami acace kakhulu.Lapha ngendlela, ukudweba amaqembu amaningana amandla noma umugqa wokuhlukanisa umhlabathi amaningana kufanele uqaphele ukuthi ungashiyi igebe, ukuze amaqembu amabili amandla amancane-wesifunda, futhi angabangela ukuxhumana kwendawo kuvinjiwe (ukuze iqembu le amandla ahlukene).
VII.Izinga lokucubungula alichazwanga ngokucacile
1. Idizayini yephaneli eyodwa kungqimba lwe-TOP, njengokungangezi incazelo yento enhle nebi, mhlawumbe eyenziwe ngebhodi efakwe kudivayisi hhayi ukushisela okuhle.
2. isibonelo, umklamo webhodi onezingqimba ezine usebenzisa i-TOP mid1, i-mid2 ezansi izendlalelo ezine, kodwa ukucubungula akubekwa ngale ndlela, okudinga imiyalelo.
VIII.Idizayini yebhulokhi yokugcwalisa kakhulu noma ibhulokhi yokugcwalisa ngokugcwaliswa komugqa omncane kakhulu
1. Kukhona ukulahleka kwedatha yokudweba ukukhanya ekhiqiziwe, idatha yokudweba ukukhanya ayiphelele.
2. Ngenxa yokuthi ibhulokhi yokugcwalisa ekusetshenzisweni kwedatha yokudweba ukukhanya isetshenziswa umugqa ngomugqa ukudweba, ngakho-ke inani ledatha yokudweba ukukhanya elikhiqizwa likhulu kakhulu, landisa ubunzima bokucubungula idatha.
IX.Iphedi yedivayisi yokukhweza ebusweni ifushane kakhulu
Lokhu okokuhlolwa kokudlula nokudlula, kwedivayisi yokukhweza eminyene kakhulu, isikhala phakathi kwezinyawo zayo ezimbili sincane kakhulu, iphedi nayo incane kakhulu, inaliti yokuhlola yokufaka, kufanele ibe phezulu naphansi (kwesokunxele nakwesokudla) indawo enyakazayo, njengokuthi idizayini yephedi yimfushane kakhulu, nakuba ingathinti ukufakwa kwedivayisi, kodwa izokwenza inaliti yokuhlola ingalungile ukuthi ingavuli indawo.
X. Isikhala segridi yendawo enkulu sincane kakhulu
Ukwakheka komugqa wegridi yendawo enkulu enomugqa phakathi konqenqema kuncane kakhulu (ngaphansi kuka-0.3mm), ekukhiqizeni ibhodi lesifunda eliphrintiwe, inqubo yokudlulisa izibalo ngemuva kokuthuthukiswa kwesithunzi kulula ukukhiqiza ifilimu eningi ephukile. enamathiselwe ebhodini, okuholela emigqeni ephukile.
XI.I-foil yethusi yendawo enkulu esuka kuhlaka lwangaphandle lwebanga iseduze kakhulu
Indawo enkulu icwecwe lethusi elisuka kuhlaka lwangaphandle kufanele libe okungenani isikhala esingu-0.2mm, ngoba esimweni sokugaya, njengokugaya kucwecwe lethusi kulula ukubangela ukungqubuzana kwe-foil yethusi futhi kubangelwa inkinga yokumelana ne-solder off.
XII.Ukuma komklamo womngcele akucacile
Amanye amakhasimende kusendlalelo se-Keep, isendlalelo Sebhodi, isendlalelo esingaphezulu phezu, njll. aklanywe umugqa wokuma futhi le migqa yomumo ayidluleli, okuholela ekutheni abakhiqizi be-pcb kube nzima ukunquma ukuthi yimuphi umucu womumo ozophumelela.
XIII.Idizayini yesithombe engalingani
Isendlalelo sokuplating esingalingani lapho ihluzo ze-plating zithinta ikhwalithi.
XIV.Indawo yokubeka ithusi inkulu kakhulu uma kusetshenziswa imigqa yegridi, ukugwema amabhamuza e-SMT.
