Xa kukho isidingo sokutshintsha i-IC kwi-ICB kuyilo lwesekethe, masibe nenxaxheba kwiingcebiso xa kuthatha indawo ye-I I-I II ukunceda abaqulunqi boyilo ngakumbi kuyilo lwesekethe.
1. Faka ngokuthe ngqo
Ukufakelwa ngokuthe ngqo kubhekisa ngokuthe ngqo kutshintsha ngokuthe ngqo i-IC ye-IC kunye nezinye ii-IC ngaphandle kotshintsho, kwaye umsebenzi ophambili kunye nezihlobo zomatshini aziyi kuchaphazeleka emva kokufakwa endaweni.
Umgaqo-siseko wokutshintshwa ngu: Umsebenzi, isalathiso sentsebenzo, ifomu yephakheji, ukusetyenziswa kwePIN, inombolo yePIN kunye nexesha lokuphumla kwe-IC Umsebenzi ofanayo we-IC awubhekiseli nje kumsebenzi omnye, kodwa kunye ne-logic efanayo yelogic, oko kukuthi, iziphumo kunye nenqanaba le-intengared, i-intertage, kunye ne-interlity ye-interlity kufuneka ifane. Izalathi zeNtsebenzo zibhekisa kwiiparamitha eziphambili ze-Ic's Abathathi-nxaxheba ngamandla asezantsi kufuneka banyuse ubushushu.
01
Ukufakwa endaweni yohlobo olufanayo lwe-IC
Ukutshintshwa kohlobo olufanayo lwe-Ic kuxhomekeke ngokubanzi. Xa ufaka isekethe edityanisiweyo ye-PCB, yilumkele ukuba ungazenzi impazamo kwicala, kungenjalo, isekethe elidityanisiweyo lePCB lingatshiswa xa amandla evuliwe. Elinye i-Amplimine yoMgca we-Amplimie I-I-I-I-I-I-I-I-I-I-I-I-I-ICWISI YOKUGQIBELA, NOWOW NOKWENZA, kodwa umkhombandlela we-imeyile yePIN wahlukile. Umzekelo, i-Amlifier ye-Amlifier ICLA4507 ine "i-pins" engathandekiyo, kunye nezikhokelo ze-pin (amachaphaza amachaphaza), i-IC, njl.
02
Ukufakwa kwe-ICS ngeleta efanayo ye-prefix kunye neenombolo ezahlukeneyo
Ngalo lonke ixesha imisebenzi yolu hlobo lokufaka endaweni iyafana, i-PCB yesekethe yangaphakathi kunye neepakethi zombane zahlukile kancinane, kwaye zinokufakwa ngqo omnye komnye. Umzekelo: I-ICLA1363 kwaye i-LA1365 ifakwe kwisandi, eli Lalter Yongeza i-lerner diode ngaphakathi kwi-PIN 5 kunangaphambili, kwaye abanye banjalo.
Ngokubanzi, ileta yangaphambili ibonisa umenzi kunye nodidi lwesekethe ye-PCB. Amanani emva kokuba ileta yangaphambili iyafana, kwaye uninzi lwazo lunokutshintshwa ngokuthe ngqo. Kodwa kukho namatyala akhethekileyo akhethekileyo. Nangona amanani ayafana, imisebenzi yahluke ngokupheleleyo. Umzekelo, i-HA1364 i-IC, kunye ne-upc1364 yi-ICKI YOKUZIPHATHA; Inani lingama-4558, iPIN ye-8 i-Amplifier NJM458, kwaye iPIN ye-14 ye-CD4558 yedijithali ye-CBB; Ke ngoko, bobabini abanakuthathelwa indawo konke konke. Ke kufuneka sijonge umsebenzi we-PIN.
Abanye abavelisi bangenzi iitshipsi ezingenzi i-ic kwaye baziqhube kwimveliso ebizwa emva komzi-mveliso, kunye nezinye iimveliso eziphuculweyo ukuphucula iparamitha ethile. Ezi mveliso zihlala zibizwa ngeemodeli ezahlukeneyo okanye zahlula-hlulwa zizimamva zemodeli. Umzekelo, i-A380 kunye ne-UPC1380 inokutshintshwa ngokuthe ngqo, kwaye i-A5620, iti5620, i-DG5620, njl njl.
2. Ukufakwa ngokungathanga ngqo
Ukufakwa ngokungathanga ngqo kubhekisele kwindlela enokuthi ithathelwe indawo ngqo yindlela yokuguqula i-PCB yePCB yePCB, iguqula okanye isuse izinto ezizezona, njl njl.
Umgaqo-siseko wokufakwa endaweni: I-IC esetyenziswe endaweni inokuthi yahluke kwi-IC yoqobo ye-IC enemisebenzi eyahlukeneyo yePIN kunye nembonakalo eyahlukeneyo, kodwa imisebenzi kufuneka ifane; Ukusebenza komatshini wokuqala akufuneki kuchaphazeleke emva kokufakwa endaweni.
01
Ukufaka i-iCIC ezipakishwe
Kwiitshipsi ze-IC zohlobo olufanayo, kodwa ngeemilo ezahlukeneyo zephakheji, kuphela izikhonkwane zesixhobo esitsha kufuneka siphinde siphinde siphinde siphinde siphinde siphinde siphinde siphinde siphinde siphinde siphinde siphinde siphinde siphinde sibe nemilo. Umzekelo, isekefiki ye-AftPCB ye-ASTPPCB CA3064 kunye ne-CA3064E, owayeyiphayisela iphakheji enemibhobho ye-radial: I-radter yiphakheji yeProteyisi ye-intanethi, kwaye zinokuqhagamshelwa ngokomsebenzi wePiney. I-ICan-Row-Rood7114, i-AN7115 ne-LA411102 zifana nefomathi yephakheji, kwaye i-show kunye ne-swink i-dainks ziyi-180. I-A520 ye-APME -20 yoMgca-kwi-16 yePIN ene-spin-pin-pinki ye-SIT kunye neti ye-Tea5620 in-intanethi ye-Intanethi. Izikhonkwane 9 ne-10 zikwicala lasekunene lesekethe elihlanganisiweyo le-PCB, elilingana nobushushu be-A5620. Ezinye izikhonkwane zalowo mbini zilungiselelwe ngendlela efanayo. Qhagamshela i-9ti kunye ne-10 ye-pins emhlabeni oza kuyisebenzisa.
02
Imisebenzi yesekethe i-PCB iyafana kodwa imisebenzi ye-pin nganye ye-LC eyahlukileyo
Ukutshintshwa kunokwenziwa ngokwemigangatho ethile kunye nemiyalelo yohlobo ngalunye lwe-IC. Umzekelo, imveliso yomqondiso ye-AGC kunye nevidiyo kwiTV inomahluko phakathi kwe-polacy elungileyo nengalunganga, lo gama nje i-inverter iqhagamshelwe kwi-terminal yemveliso, inokutshintshwa.
03
Ukufakwa kwe-ICS ngeplastiki enye kodwa imisebenzi eyahlukeneyo
Olu hlobo lokufaka endaweni kufuneka lutshintshe i-Piphe PCB kunye nolungiselelo lwePIN, lufuna ulwazi oluthile lwethiyori, olugqibeleleyo, kunye namava axabisekileyo kunye nezakhono.
04
Ezinye iinyawo ezingenanto azifanele zibekwe ngaphandle kwemvume
Ezinye zepins ezikhokelayo kwisekethe yangaphakathi yePCB kunye nesekethe yesicelo sePCB ayiphawulwanga. Xa zininzi izikhonkwane eziphithizelayo, akufuneki zibekwe phantsi ngaphandle kogunyaziso. Ezi zikhonkwane zikhokelayo zitshintshile okanye izikhonkwane zendawo, kwaye ngamanye amaxesha zisetyenziswa njengonxibelelwano lwangaphakathi.
05
Ukudibanisa okukhoyo
Ukutshintshwa kokutshintshwa kwakhona kukuphinda-phinda iinxalenye zesekethe ezingabonakaliyo ze-ic ezininzi zemodeli efanayo yokutshintsha i-IC ekusebenzeni kakuhle. Isebenza kakhulu xa i-ic ye-ntweni ayifumaneki. Kodwa kuyafuneka ukuba i-PCB yesekethe elungileyo ngaphakathi kwi-IC isetyenziswe kufuneka ibe nePIN.
Isitshixo sokungathanga ngqo kukufumanisa iiparamitha ezisisiseko ze-IC ezimbini ezithenjiweyo, isekethe yangaphakathi ye-PCB, umsebenzi wePIN nganye, kunye nolwalamano lwe-IC. Qaphela umsebenzi wokwenyani.
(1) Ukulandelelana kwenani lezikhonkwane zesekethe ezihlanganisiweyo zePCB akufuneki zidityaniswe ngendlela engeyiyo;
.
. Ukuba i-voltagen yokuhambisa amandla kwisekethe ye-PCB iphezulu, zama ukunciphisa i-voltage; Ukuba i-voltage iphantsi, kuxhomekeke ekubeni ingaba i-II i-IC enokusebenza;
(4) Emva kokutshintshwa, ukusebenza okukhoyo okwangoku kwee-IC kufuneka kulinganiswe. Ukuba okwangoku inkulu kakhulu kunexabiso eliqhelekileyo, oko kuthetha ukuba isekethe i-PCB ingaba uyazichwayitile. Ngeli xesha, ukucocwa kwe-decoupling kunye nohlengahlengiso kuyadingeka. Ukuba inzuzo yahlukile kwasekuqaleni, ukuxhathisa komphengululi wengxelo kungalungiswa;
(5) Emva kokutshintshwa, igalelo kunye nokunyanzeliswa kwe-IC kufuneka kutshatise isekethe ye-PCB; Jonga amandla ayo okuqhuba;

Guqula amacandelo e-IC
Ngamanye amaxesha izinto zakhanda zinokusetyenziselwa ukutshintsha indawo eyonakeleyo ye-IC ukubuyisela umsebenzi wayo. Ngaphambi kokuba kutshintshe imigaqo, kuya kufuneka uqonde uMgaqo-nkqubo waNgaphakathi we-IC, i-vortage eqhelekileyo yePIN nganye, umzobo we-wave kunye nomgaqo wokusebenzela kunye nomgaqo wokusebenzela wesekethe ye-PCB kunye nezinto eziphezulu. Kwakhona cinga:
.
. Ukuba i-ATPLIPID ye-AMPLPIIER iyonakalisiwe, kwisekethe eqhelekileyo yesicelo sePCB kunye nesekethe yangaphakathi ye-PCB, iqulunqwe i-AMPLBIP ephakathi, ukucalucaza rhoqo kunye nokuqhubela phambili. Indlela yokufaka umqondiso ingasetyenziselwa ukufumana indawo eyonakeleyo. Ukuba inxalenye ye-Audio Amlifier yonakalisiwe, izinto ezigqityiweyo zinokusetyenziswa endaweni yoko.
