Ubunzima beCopper kwi-PCB Manufacturing: Isikhokelo esiSiseko

Iibhodi zesekethe eziprintiweyo (PCBs) ziyinxalenye ye-electronics yanamhlanje. Basebenza njengomqolo wezixhobo zombane, ukubonelela ngeqonga lokudityaniswa kwezinto zombane.Ubhedu lugqwesileyo lokuqhuba umbane kwaye lusetyenziswa kakhulu kwimveliso yePCB.

Kwinkqubo yokwenziwa kwePCB, ubunzima bobhedu budlala indima ebalulekileyo.Ubunzima bobhedu bubhekisela kubunzima okanye ubuninzi bobhedu obusetyenziswe kumphezulu webhodi yesiphaluka. Ubunzima bobhedu olusetyenziswa kwimveliso ye-PCB buchaphazela ngokuthe ngqo iipropati zombane kunye nezomatshini zebhodi. Kule bhlog, siza kuphonononga ubunzima bobhedu obahlukeneyo obusetyenziswa kwimveliso yePCB kunye nokubaluleka kwabo.

Ukuqonda ubunzima beCopper kwi-PCB Manufacturing

Ubunzima bobhedu buqhele ukulinganiswa ngee-ounces ngesikwere sonyawo (oz/ft²). Awona matye obunzima bobhedu asetyenziswa kakhulu kwi-PCB yokuvelisa asusela kwi-0.5 oz/square foot (17 µm) ukuya kwi-3 oz/square foot (105 µm). Ezi zisindo zigqiba ukutyeba kobhedu lweeleya zangaphandle zePCB, iileya zangaphakathi, kunye nemingxuma yobhedu ecayiweyo.

Ukukhethwa kobunzima bobhedu kuxhomekeke kwizinto ezifana nokusebenza kombane okufunekayo, amandla omatshini kunye neendleko. Makhe

jonga nzulu kwiintsimbi ezahlukeneyo zobhedu kunye nokusetyenziswa kwazo kwimveliso yePCB.

1. 0.5 oz/ft2 (17 µm) Ubunzima bobhedu:
Obu bubunzima bobhedu obukhaphukhaphu obusetyenziswa kwimveliso yePCB. Idla ngokusetyenziswa kwizicelo ezilula nezikhaphukhaphu zePCB. Ezi bhodi zidla ngokusetyenziswa kwi-electronics yabathengi apho iindleko kunye nobunzima zizinto eziphambili zokuqwalaselwa. Nangona kunjalo, ukucuthwa kobhedu obuncitshisiweyo buchaphazela ukukwazi ukuthwala imisinga ephezulu kwaye kunokubangela ukwanda kokumelana.

2. 1 oz/square foot (35 µm) ubunzima bobhedu:
Esi sesona sisindo sobhedu sisetyenziswa kakhulu kwimveliso yePCB. Ibeka ibhalansi phakathi kokusebenza kunye nokusebenza kakuhle kweendleko. IiPCB ezine-1 oz/sq. I-ft. ubunzima bobhedu bunokusingatha imisinga ephakathi kwaye ifanelekile kwiintlobo ezahlukeneyo zezicelo, kubandakanywa unxibelelwano lwe-telecommunications, i-automotive and industrial electronics.

3. 2 oz/square foot (70 µm) ubunzima bobhedu:
Njengoko imfuno ephezulu yokuthwala yangoku isanda, ii-PCB ezinobunzima bobhedu bee-ounces ezi-2 / unyawo lwesikwere zibalulekile. Eyaziwayo ngokuphuculwa kwe-thermal conductivity, ezi bhodi ziqhele ukusetyenziswa kwi-electronics yamandla, i-amplifiers yamandla aphezulu, iinkqubo ze-UPS kunye nezinye izicelo ezifuna ukukwazi ukuthwala ngoku.

4. 3 oz/ft2 (105 µm) Ubunzima bobhedu:
IiPCB ezinobunzima bobhedu bee-ounces ezi-3 ngonyawo lwesikwere zithathwa njengeebhodi zobhedu ezinzima. Ezi bhodi zisetyenziselwa izicelo ezifuna amandla amakhulu okuphatha ngoku okanye ukutshatyalaliswa kobushushu obungcono. Eminye imizekelo ibandakanya iinkqubo zokuhambisa amandla, iitshaja zebhetri zangoku eziphezulu, kunye nezilawuli zeemoto.

Ukubaluleka kobunzima beCopper kwi-PCB Manufacturing

Ukukhetha ubunzima bobhedu obufanelekileyo bubalulekile ekuqinisekiseni ukusebenza kwePCB kunye nokuthembeka. Nantsi eminye imiba ephambili eqaqambisa ukubaluleka kobunzima bobhedu:

1. Ukusebenza kombane:
Ubunzima bobhedu bumisela ukukwazi kwePCB ukuthwala okwangoku ngaphandle kokudala ukuxhathisa okugqithisileyo. Ubunzima bobhedu obungonelanga bunokubangela ukuchasana nokunyuka, okukhokelela ekunciphiseni kwamandla ombane kunye nokushisa kwebhodi. Ngakolunye uhlangothi, ubunzima bobhedu obuphezulu buvumela ukuphathwa kakuhle kwangoku kunye nokuchasana okuphantsi.

2. Amandla oomatshini:
Ukongeza ekuqhutyweni kombane, ubhedu lukwabonelela ngokuqiniswa koomatshini kwi-PCB. Ubunzima bobhedu obufanelekileyo bongeza amandla kunye nokuqina kwibhodi yesekethe, evumela ukuba ixhathise ukugoba, ukulwa, okanye olunye uxinzelelo lomzimba.

3. Ulawulo lobushushu:
Ubhedu ngumqhubi obalaseleyo wobushushu. Ubunzima bobhedu olwaneleyo bunceda ukutshabalalisa ngokufanelekileyo ubushushu obuveliswa ngamacandelo afakwe kwi-PCB. Oku kuthintela uxinzelelo lwe-thermal okanye ukungaphumeleli kwecandelo ngenxa yokushisa, ukuqinisekisa ixesha elide kunye nokuthembeka kwebhodi.

4. Khangela ububanzi kunye nezikhokelo zezithuba:
Ubunzima bobhedu buchaphazela ububanzi bomkhondo kunye nezikhokelo zezithuba ngexesha loyilo lwePCB kunye noyilo. Ubunzima bobhedu obuphezulu bufuna ububanzi bomkhondo obanzi kunye nezithuba ukuvumela ukuhamba ngoku ngokufanelekileyo kwaye kuthintelwe ukunyuka kwamaqondo obushushu.

Ukuququmbela

Isishwankathelo,ukukhetha ubunzima bobhedu obufanelekileyo kubalulekile ekuyileni ukusebenza okuphezulu kunye ne-PCB ethembekileyo.Ukhetho luxhomekeke kwiimfuno ezithile zesicelo, kuthathelwa ingqalelo ukusebenza kombane, amandla omatshini kunye neemfuno zolawulo lwe-thermal. Nokuba zizinto zombane ezikhaphukhaphu zabathengi okanye usetyenziso lwamashishini anamandla amakhulu, ubunzima bobhedu budlala indima ebalulekileyo kwimveliso yePCB kwaye kufuneka buqwalaselwe ngononophelo ngexesha loyilo.
