Ungqingqwa kangakanani ubhedu kwiiPCB ezibhetyebhetye?

Xa kuziwa kwii-PCB eziguquguqukayo (iibhodi zesekethe eziprintiweyo), enye yezinto eziphambili ekufuneka ziqwalaselwe bubunzima bobhedu. Ubhedu ludlala indima ebalulekileyo ekusebenzeni kunye nokuqina kwee-PCB eziguquguqukayo kwaye ngoko ke ngumba obalulekileyo omele uqondwe.Kwesi sithuba sebhlog, siza kungena nzulu kumxholo wokuqina kobhedu kwiiPCB eziguquguqukayo, kwaye iShenzhen Capel Technology Co., Ltd. ixhasa ukubhitya kobhedu, sixoxa ngokubaluleka kwayo kunye nendlela echaphazela ngayo ukusebenza kwebhodi iyonke.

Ukubaluleka kobunzima bobhedu kwi-PCB eguquguqukayo

Ubhedu lukhetho lokuqala kwiiPCBs ngenxa yokuhanjiswa kombane okugqwesileyo kunye nokumelana nomhlwa.Kwii-PCB eziguquguqukayo, ubhedu lusetyenziswa njengento eqhubayo evumela ukuba umbane ujikeleze kwisekethe. Ubukhulu bobhedu buchaphazela ngokuthe ngqo ukusebenza kunye nokusebenza kwe-PCB eguquguqukayo. Nasi isizathu sokuba ubukhulu bobhedu bubalulekile:

1. Umthamo wokuthwala wangoku: Ubukhulu bobhedu bumisela ukuba ingakanani yangoku i-PCB inokuthwala ngokukhuselekileyo ngaphandle kokutshisa okanye ukubangela iingxaki zombane.Iileya zobhedu ezityebileyo zinokuphatha ngokufanelekileyo imisinga ephezulu, iqinisekisa ukusebenza kakuhle kwesekethe ye-flex.

2. Ukunyaniseka komqondiso: IiPCB eziguquguqukayo zihlala zisetyenziswa kwizicelo ezifuna imfezeko yomqondiso ophezulu, njenge-aerospace, izixhobo zonyango, kunye nonxibelelwano.Ubunzima bobhedu buchaphazela i-impedance ye-trace, iqinisekisa ukuba iimpawu zisasazeka ngokuchanekileyo kunye nokulahlekelwa okuncinci okanye ukuphazamiseka.

3. Amandla omatshini: Iibhodi zeesekethe eziprintiweyo eziguquguqukayo zenzelwe ukuba ziguquguquke, oku kuthetha ukuba zibonakaliswe ngokugoba rhoqo, ukugoba kunye nokudibanisa.Uluhlu lobhedu lunika amandla omatshini kwisekethe kwaye luthintele ukuqhekeka okanye ukuphuka kwiindlela zokuqhuba. Ukutyeba okwaneleyo kobhedu kuqinisekisa ukuba iPCB ihlala yomelele kwaye yomelele ubomi bayo bonke.

Funda malunga nomlinganiselo wobunzima bobhedu

Kwilizwe le-PCB elibhetyebhetye, ubukhulu bobhedu buqhele ukulinganiswa ngee-ounces ngesikwere sonyawo (oz/ft²) okanye iimicrometers (μm). Olona khetho luqhelekileyo lokutyeba kobhedu kwiiPCB ezibhetyebhetye yi-0.5 oz (17.5 µm), 1 oz (35 µm), 2 oz (70 µm), kunye ne-3 oz (105 µm). Ukukhethwa kobunzima bobhedu kuxhomekeke kwiimfuno ezithile zesicelo ezifana nokuthwala kwangoku kunye namandla omatshini.

Izinto ezichaphazela ukukhetha ubukhulu bobhedu

Izinto ezininzi zinefuthe ekukhetheni ukutyeba kobhedu kwiPCB ebhetyebhetye, kubandakanya:

1. Iimfuno zangoku: Usetyenziso oluphezulu lwangoku lufuna imigangatho yobhedu engqindilili ukuqinisekisa ukuthwala okusebenzayo ngoku.Ukuqwalaselwa kufuneka kunikwe ubuninzi bangoku isiphaluka esiya kudibana nokuphepha ukugqithiswa kobhedu okanye ukuhla kwamandla ombane.

2. Izithintelo zesithuba: Izixhobo ezincinci, ezixineneyo zinokufuna iileya zobhedu ezibhityileyo ukuze zilingane kwindawo ekhoyo ekhoyo.Nangona kunjalo, esi sigqibo kufuneka silinganiswe ngononophelo ngokuchasene nomthamo wangoku kunye neemfuno zamandla oomatshini.

3. Ukuguquguquka: Ukuguquguquka kwePCB kuchaphazeleka bubunzima bobhedu.Iingqimba zobhedu ezityebileyo ziqhelekile ukuba nzima, zinciphisa ukuguquguquka okupheleleyo kwesekethe. Kwizicelo eziguquguqukayo kakhulu, ubukhulu bobhedu obuphantsi bukhethwayo.

Amanyathelo okuthintela ukwenziwa

Iinkqubo zokwenziwa kwe-PCB eziguquguqukayo zenzelwe ukulungiselela uluhlu olubanzi lokutyeba kobhedu. Nangona kunjalo, ubukhulu bobhedu oluthile bunokufuna izilumkiso ezongezelelweyo okanye ubuchule obukhethekileyo ngexesha lenkqubo yokuvelisa. Iileya zobhedu ezishinyeneyo zinokufuna amaxesha amade okuhombisa ukufezekisa ipateni yesekethe efunekayo, ngelixa iileya ezibhityileyo zobhedu zifuna ukucutshungulwa okuthe kratya ukunqanda umonakalo ngexesha lendibano.

Ukusebenza ngokusondeleyo nomvelisi we-PCB kubalulekile ukuqonda nayiphi na imida okanye iingqwalasela ezithe ngqo kubunzima bobhedu olufunekayo. Oku kuqinisekisa inkqubo yokuvelisa ngempumelelo ngaphandle kokuchaphazela ukusebenza kwePCB.
