Ubushushu obuveliswe zizixhobo ze-elektroniki ngexesha lokusebenza zibangela ukuba amaqondo obushushu angaphakathi kwezixhobo anyuke ngokukhawuleza. Ukuba ubushushu abukhali ngexesha, izixhobo ziya kuqhubeka nokukhumbula, icebo liya kusilela ngenxa yokugxeka, kwaye ukuthembeka kwezixhobo ze-elektroniki ziya kuhla. Ke ngoko, kubaluleke kakhulu ukuqaqambisa ubushushu kwibhodi yesekethe.

Uhlalutyo lweFaratoration of Iarhed Ukunyuka kweBhodi yeSekethe eprintiweyo

Isizathu ngqo sobushushu obunyukayo seBhodi ePriple kuLube zizixhobo zokusetyenziswa kwamandla esiphathwayo, kunye nezixhobo ze-elektroniki zinezinto zokusebenzisa amandla, kunye neenguqu zobushushu kunye nokusetyenziswa kwamandla.

Ii-phenomena ezimbini zobushushu ziphakama kwiibhodi eziprintiweyo:
(1) iqondo lobushushu lendawo linyuka okanye iqondo elikhulu lendawo linyuka;
(2) Ukunyuka kweqondo lobushushu ixesha elifutshane okanye ukunyuka kweqondo lobushushu ixesha elide.

Xa uhlalutya ukusetyenziswa kwamandla e-PCB, ngokubanzi kwezi zinto zilandelayo.

Ukusetyenziswa kwamandla ombane
(1) hlalutya ukusetyenziswa kwamandla kwindawo nganye;
(2) Hlaziya ukusasazwa kokusetyenziswa kwamandla kwiBhodi yeSekethe yePCB.

2. Ulwakhiwo lweBhodi ePriple
(1) Ubungakanani beBhodi ePrinta;
(2) Izixhobo zeBhodi ePrinta.

I-3. Indlela yokufaka yeBhodi eprintiweyo
(1) Indlela yokufaka (efana nokufakelwa nkqo kunye nokufakwa ngokuthe ngqo);
(2) imeko yokutywina kunye nomgama ukusuka kwi-cher.

4. Imitha ye-thermal
(1) Ukusasaza komhlaba webhodi eprintiweyo;
(2) Umahluko wobushushu phakathi kwebhodi eprintiweyo kunye nomphezulu ocacileyo kunye nobushushu babo obugqibeleleyo;

5. Ukuqulunqwa kobushushu
(1) Faka i-radiator;
(2) Ukuqulunqwa kwezinye iinxalenye zoFakelo.

6. Intuthuzelo ye-thermal
(1) Ingqungquthela yendalo;
(2) Ukunyanzeliswa okupholisayo.

Uhlalutyo lwezi zinto zingasentla kwi-PCB yindlela esebenzayo yokusombulula ubushushu beBhodi eprintiweyo. Ezi zinto zihlala zinxulumene kwaye zixhomekeke kwimveliso nakwinkqubo. Uninzi lwezinto kufuneka luhlaziywe ngokwemeko yokwenyani, kuphela kwimeko ethile. Kuyo kuphela kule meko kuphela apho iiparamitha zeqondo lokushisa kunye nokusetyenziswa kwamandla zibaliwe okanye kuqikelelwa ngokuchanekileyo.

Indlela yokupholisa iBhodi yeSekethi yeSekethi

I-1. Isixhobo esivela kubushushu esivelisa ubushushu kunye ne-shart sink kunye neplate yokusebenza kobushushu
Xa izixhobo ezimbalwa kwi-PCB zivelisa inani elikhulu lobushushu (ngaphantsi kwe-3), isinki esitshisayo okanye umbhobho wobushushu ongongezwa kwisixhobo esivelisa ubushushu. Xa iqondo lobushushu alinakho ukuthotywa, i-fan etshisayo i-fan ingasetyenziselwa ukuphucula isiphumo se-Heb. Xa kukho izixhobo zokufudumeza (ngaphezulu kwe-3), ikhava ye-Servipation enkulu (iBhodi) inokusetyenziswa. I-radiator ekhethekileyo ngokwesiko ngokwesiko kunye nokuphakama kwesixhobo sokufudumeza kwibhodi ye-PCB okanye kwi-radiator enkulu efihlakeleyo yokususa ubude bezinto ezahlukeneyo. Qinisa ikhava yokulahla inkunkuma kwindawo yecandelo, kwaye uqhagamshelane necandelo ngalinye ukuze ubushushu bubushushu. Nangona kunjalo, ngenxa yokungqinelana kakubi kwamacandelo ngexesha lokuhlangana kunye ne-welding, isiphumo sokushisa ubushushu asilunganga. Ngokwesiqhelo isigaba senqanaba le-thermal yenqanaba le-thermal yongezwa kwicandelo lokuphucula isiphumo se-Heat.

2. Ukuhlanjwa kobushushu ngebhodi ye-PCB ngokwayo
Okwangoku, iipleyiti ezisetyenziswa ngokubanzi ze-PCB i-Copper-Class / i-Epoxy Glass Clout okanye i-Epoxy Glass okanye i-phenolin restin resestic ares, kunye nenani elincinci le-copper esetyenziswayo. Nangona la matyala anengxaki yokusebenza egqwesileyo kunye nokusebenza okusebenzayo, banamafutha obushushu obungalunganga. Njengendlela yokuphumelela kobushushu kumacandelo aphezulu okuvelisa ubushushu, i-PCB ngokwayo ayinakulindeleka ukuba iqhube ishushu kwi-PCB, kodwa ukubuphatha ubushushu kumphezulu wecandelo lomoya ojikelezileyo. Nangona kunjalo, njengoko iimveliso ze-elektroniki zingene kwi-mineatherition yamacandelo, ufakelo oluphezulu, kunye nendibano-ephezulu yobushushu, akwanelanga ukuxhomekeka kumphezulu wezinto ezinokubufumana ubushushu. Kwangelo xesha, ngenxa yokusetyenziswa okukhulu kwamacandelo aphezulu anjenge-QFP kunye ne-BGA, ubushushu obuveliswe ngamacandelo budluliselwe kwibhodi ye-PCB ngezixa ezikhulu. Ke ngoko, eyona ndlela ilungileyo yokusombulula ukungasebenzi kobushushu kukuphucula amandla obushushu be-PCB ngokudibana ngqo nento yokufudumeza. Indlela yokuziphatha okanye ukukhupha.

3. Ukwamkela uyilo olufanelekileyo lokuqalisa ukufezekisa i-SURP
Kuba ukuqhubela kwe-shirrm ye-resin kwiphepha alilunganga, kwaye imingxunya yobhedu imingxunya nemingxunya isebenza kakuhle i-spectionres, ukuphucula imingxunya yolungelelwaniso lwe-therper yeyona ndlela iphambili yokuhlaselwa kobushushu.
Ukuvavanya ukwakha amandla obushushu kwi-PCB, kuyimfuneko ukubala ukuqhutywa kwe-PARMY NOKUGQIBELA

I-4. Kwizixhobo ezisebenzisa ukupholisa umoya zasimahla, kungcono ukucwangcisa isekethe ehlanganisiweyo (okanye ezinye izixhobo) ngokuthe nkqo okanye ngokuthe tye.

5. Izixhobo kwiBhodi enye eprintiweyo kufuneka zicwangciswe ngokobushushu bomshushu kunye nobushushu kangangoko kunokwenzeka. Izixhobo ezinesizukulwana esincinci sesishushu okanye ukungavisisani kobushushu (ezinjengohambo oluhlangeneyo, iisekethe ezincinci, iisekethe ezihlanganisiweyo (ezinjengeempazamo ezihlangeneyo, njl njl.)

I-6. Kwindlela ethe tyaba, izixhobo ezinamandla amandla kufuneka zibekwe kufutshane kangangoko kuthi vala iBhodi eprintiweyo ukuba inciphise indlela yokudluliselwa kobushushu; Kwindlela ethe nkqo, izixhobo ezinamandla ezinamandla kufuneka zibekwe ecaleni kweBhodi eprintiweyo ukunciphisa ubushushu bezi zixhobo xa zisebenza kwezinye iimpembelelo.

I-7. Isixhobo esinobuthathaka ubushushu sibekwe kwindawo enamaqondo obushushu asezantsi (njengasezantsi kwesixhobo). Ungaze uyibeke ngqo ngaphezulu kwesixhobo esivelisa ubushushu. Izixhobo ezininzi kukhethwa ukuba ubotshwe kwindiza ethe tyaba.

8. Ukuhlanjwa kobushushu kwiBhodi ePriple kwizixhobo ikakhulu kuxhomekeke kuhambo lomoya, ke indlela yokuhamba komoya kufuneka ifundwe kuyilo, kwaye iBhodi yeSekethe eprintiweyo iprintwe ngokufanelekileyo. Xa umoya uqukuqeyo, uhlala udla ngokuhamba apho ukumelana nawo kuncinanana, ke xa kuthelekiswa izixhobo kwiBhodi yeSiphako eprintiweyo, kuyimfuneko ukuthintela ukuya kwindawo ethile. Uqwalaselo lweebhodi zesekethe ezininzi eziprintiweyo kulo matshini uphela kufuneka unikele ingqalelo kwingxaki enye.

9. Kulumkele ukugxininiswa kwamabala ashushu kwi-PCB, hambisa amandla ngokulinganayo kwi-PCB kangangoko kunokwenzeka, kwaye ugcine ukusebenza kobushushu be-PCB engaphezulu kwaye iyahambelana. Kuhlala kunzima ukufezekisa ukusasazwa ngokungqongqo kwenkqubo yoyilo, kodwa kuyimfuneko ukuthintela iindawo ezinobunzima obuninzi kakhulu ukuthintela ukusebenza kwesiqhelo. Ukuba iimeko zemvume, uhlalutyo oluqhelekileyo lokusebenza kwesekethe elishicilelweyo liyimfuneko. Umzekelo, ukuhlalutya kwenkqubo ye-Irmal ye-Irmal ye-Irmal yenkqubo eyongeziweyo kwisoftware yoyilo lobungcali ye-PCB kunganceda ukuyilwa ukwenza uyilo lwesekethe.
