Mugihe hakenewe gusimbuza IC mubishushanyo byumuzunguruko, reka dusangire inama mugihe dusimbuye IC kugirango dufashe abashushanya neza muburyo bwumuzunguruko.

1. Gusimbuza neza
Gusimbuza mu buryo butaziguye bivuga gusimbuza imbuga y'umwimerere hamwe nandi mes ntaho bihindura, kandi imikorere nyamukuru n'ibipimo by'imashini ntibizagira ingaruka nyuma yo gusimburwa.

Ihame ryo gusimbuza ni: imikorere, indangagaciro, imiterere ya paki, Gukoresha pin, numero ya PIN hamwe nintera yo gusimbuza IC NIMWE. Igikorwa kimwe cya IC ntabwo bivuga gusa kumikorere imwe gusa, ariko nanone polarike imwe, ni ukuvuga ibisohoka hamwe na polarique, voltage, hamwe nubushobozi bwa none bigomba kuba bimwe. Ibipimo ngenderwaho bivuga bivuga ibipimo ngenderwaho by'icyuma (cyangwa umurongo w'ingenzi uranga), dispitation ntarengwa, intera ndende, hamwe n'ibimenyetso bitandukanye by'ibimenyetso hamwe n'ibisohoka ku mpingane y'ic. Gusimburwa nimbaraga nke zigomba kongera ubushyuhe.

01
Gusimbuza ubwoko bumwe bwa IC
Gusimbuza ubwoko bumwe bwa IC ni Mubisanzwe. Mugihe ushyiraho umuzunguruko uhujwe na PCB, witondere kudakora amakosa mu cyerekezo, bitabaye ibyo, imizunguruko ihuriweho na PCB ishobora gutwikwa mugihe imbaraga zifunguye. Imbaraga zimwe zumurongo wa Amplifier ics zifite icyitegererezo kimwe, imikorere, nibiranga, ariko icyerekezo cya gahunda ya PIN kiratandukanye. Kurugero, imbaraga zibiri-zo mu miyoboro ya amplifier icla4507 zifite "nziza" na "ibibi bya pin (oudix, kandi inkenga ni" et.

02
Gusimbuza ics hamwe ninyuguti imwe yibanze hamwe numubare utandukanye
Igihe cyose ibikorwa bya pin byubwoko nkubu usimbuye ni kimwe, progaramu yumuzunguruko wimbere hamwe namashanyarazi aratandukanye gato, kandi birashobora kandi gusimburwa. Kurugero: Icla1363 na La1365 bashyizwe mu majwi, aba nyuma bongera kuri diode yimbere mu iC 5 kurenza iyambere, nabandi birasa.

Muri rusange, ibaruwa yibanze yerekana uwukora nicyiciro cyumuzunguruko wa PCB. Umubare nyuma yinyuguti yibanze nimwe, kandi benshi muribo barashobora gusimburwa mu buryo butaziguye. Ariko hariho kandi imanza zidasanzwe. Nubwo imibare ari imwe, imikorere iratandukanye rwose. Kurugero, ha1364 nijwi ryumvikana, na UPC1364 ni ibara ritagira ibara IC; Umubare ni 4558, 8-pin ni ugukora amplifier yimikorere NJM4558, na 14-pin ni CD4558 ya Digital PCB; Kubwibyo, bombi ntibashobora gusimburwa na gato. Tugomba rero kureba imikorere ya PIN.

Abakora bamwe bamenyekanisha amashusho ya ICYUMWE no kubitunganya kubicuruzwa byitwa uruganda, nibicuruzwa bimwe byateje imbere kugirango batezimbere ibipimo bimwe. Ibicuruzwa bikunze kwita hamwe nuburyo butandukanye cyangwa gutandukanya icyitegererezo. Kurugero, A380 na UPC1380 birashobora gusimburwa mu buryo butaziguye, na AN5620, icyayi5620, DG5620, nibindi birashobora gusimburwa mu buryo butaziguye.

2. Gusimburwa bitaziguye
Gusimbuza bitaziguye bivuga uburyo ic idashobora gusimburwa mu buryo butaziguye nuburyo bwo guhindura gato umuzunguruko wa peripherale pcb, guhinduranya gahunda yumwimerere pcb cyangwa yongeyeho cyangwa yongeraho ibice byihariye, nibindi.

Ihame ryo gusimbuza: ICC ikoreshwa mugusimbuza irashobora gutandukana nicyuma cyumwimerere hamwe nibikorwa bitandukanye bya pin no kugaragara bitandukanye, ariko imikorere igomba kuba imwe nibiranga bigomba kuba bisa nibisa; Imikorere yimashini yumwimerere ntigomba kugira ingaruka nyuma yo gusimburwa.

01
Gusimbuza ics zitandukanye
Kuri ic chip yubwoko bumwe, ariko hamwe nuburyo butandukanye, amapine yibikoresho bishya bigomba kubakwa ukurikije imiterere na gahunda yibikoresho byihariye. Kurugero, aftpcb yumuzunguruko ca3064 na ca306e, ibyambere ni paki yimodoka: Ibiranga imbere ni bibiri bya plastike, kandi birashobora guhuzwa ukurikije imikorere ya PIN. Ibice bibiri A ANOREmen An5620 yo muri ANOREmekana mu mujyi wa 16-PIN hamwe n'ubushyuhe n'icyayi5620 dual mu murongo wa 18-PIN. Amapine 9 na 10 iherereye kuruhande rwiburyo bwumuzunguruko wa PCB, bihwanye nubushyuhe bwa AN520. Ibindi bipano byombi birateguwe muburyo bumwe. Huza pin ya 9 na 10 hasi kugirango ukoreshe.

02
Ibikorwa byumuzunguruko bya PCB nibikorwa bimwe ariko umuntu kugiti cye nibisimbuza LC itandukanye
Gusimbuza birashobora gukorwa ukurikije ibipimo byihariye n'amabwiriza ya buri bwoko bwa IC. Kurugero, agc na videwo ibimenyetso byerekana kuri TV bifite itandukaniro riri hagati ya polarity nziza kandi mbi, igihe cyose inverter ifitanye isano nibisohoka kuri terminal, irashobora gusimburwa.

03
Gusimbuza ics hamwe na plastiki imwe ariko ibitandukanye
Ubu buryo bwo gusimburwa bugomba guhindura umuzunguruko wa peripherale na PIN, bisaba ubumenyi bumwe na bumwe, amakuru yuzuye, hamwe nubunararibonye bufatika nubuhanga bukize.

04
Ibirenge byubusa ntibigomba kuba bifite uburenganzira
Bimwe mubyo biyobora muri PCB byumuzunguruko byimbere bya PCB hamwe na Porogaramu ya Porogaramu ya PCB itarangwa. Iyo hari amapine yo kuyobora, ntibagomba gushingira ku burenganzira. Aya mapano ayobora ni asimburana cyangwa ngo akize, kandi rimwe na rimwe nayo ikoreshwa nkamahuza imbere.

05
Gusimbuza
Gusimbuza guhuza ni ukutera kwamazi ya PCB byumuzunguruko byangiritse bya ics nyinshi byicyitegererezo kimwe kugirango dusimbuze ic. Birakoreshwa cyane mugihe umwimerere IC idahari. Ariko birasabwa ko umuzunguruko mwiza wa PCB imbere ya IC ugomba kugira interineti PI.

Urufunguzo rwo gusimburwa butaziguye nukumenya ibipimo byibanze bya ics yasimbuwe, bihwanye byimbere pcb, imikorere ya buri pin, hamwe numubano wihuza hagati yibice bya IC. Witondere ibikorwa nyabyo.

.
. Niba ingufu za voltage mukarere ka PCB yumwimerere ari ndende, gerageza kugabanya voltage; Niba voltage ari make, biterwa nuko gusimburwa IC bishobora gukora;
(4) Nyuma yo gusimburwa, gukora akazi ka ICC bigomba gupimwa. Niba ikigezweho kinini kuruta agaciro gasanzwe, bivuze ko umuzunguruko wa PCB ashobora kwishima. Muri iki gihe, harakenewe gutesha agaciro no guhinduka birakenewe. Niba inyungu zitandukanye numwimerere, kurwanya kurwanya ibitekerezo birashobora guhinduka;
. Reba ubushobozi bwa kabiri;

Simbuza ic hamwe nibikoresho byangiritse
Rimwe na rimwe, ibice bishobora gukoreshwa kugirango bisimbure igice cyangiritse cyo kugarura imikorere yacyo. Mbere yo gusimburwa, ugomba kumva ihame ryimbere rya IC, voltage isanzwe ya buri pin, igishushanyo cya saveforme hamwe nihame ryumuzunguruko wa PCB hamwe nibigize. Tekereza kandi:

.
. Niba icllifier ya hagati yangiritse, uhereye kubisanzwe PCB Umuzunguruko na PCRice yumuryango wa PCB, igizwe na amplifier ya Audio, ivangura ryinshi ninshuro zizamura. Uburyo bwo kwinjiza ibimenyetso burashobora gukoreshwa mugushakisha igice cyangiritse. Niba igice cya Aumelifier igice cyangiritse, ibice bifatika birashobora gukoreshwa aho.
