Ukusebenza okuphezulu kokufakwa kwe-interlayer kwe-PCB enezingqimba eziningi

Kulokhu okuthunyelwe kwebhulogi, sizohlola amasu namasu ahlukahlukene okuthola ukusebenza kahle kokufakwa ngaphakathiama-PCB anezingqimba eziningi.

Ama-PCB angama-Multilayer asetshenziswa kakhulu emishinini ye-elekthronikhi ehlukahlukene ngenxa yokuminyana kwabo okuphezulu kanye nokwakheka okuhlangene. Kodwa-ke, isici esibalulekile sokuklama nokukhiqiza lawa mabhodi esekethe ayinkimbinkimbi ukuqinisekisa ukuthi izakhiwo zawo zokufakwa kwe-interlayer zihlangabezana nezidingo ezidingekayo.

I-insulation ibalulekile kuma-PCB anezingqimba eziningi njengoba ivimbela ukuphazamiseka kwesignali futhi iqinisekisa ukusebenza kahle kwesekethe. Ukwahlukanisa okungalungile phakathi kwezendlalelo kungaholela ekuvuzeni kwesignali, i-crosstalk, futhi ekugcineni ukwehluleka kwedivayisi ye-elekthronikhi. Ngakho-ke, kubalulekile ukucabangela nokusebenzisa izinyathelo ezilandelayo ngesikhathi sokuklama nokukhiqiza:

1. Khetha impahla efanele:

Ukukhethwa kwezinto ezisetshenziswa esakhiweni se-PCB ye-multilayer kuthinta kakhulu izakhiwo zayo zokufakwa kwe-interlayer. Izinto zokuvikela izinto ezifana ne-prepreg ne-core materials kufanele zibe ne-voltage ephezulu yokuwohloka, i-dielectric engaguquki ephansi kanye nesici esiphansi sokulahla. Ukwengeza, ukucabangela izinto ezinokumelana okuhle komswakama kanye nokuzinza kokushisa kubalulekile ekugcineni izakhiwo zokushisa isikhathi eside.

2. Idizayini ye-impedance elawulekayo:

Ukulawulwa okufanele kwamazinga e-impedance kumiklamo ye-PCB ye-multilayer kubalulekile ukuze kuqinisekiswe ubuqotho besignali obuphelele nokugwema ukuhlanekezelwa kwesignali. Ngokubala ngokucophelela ububanzi bokulandelela, izikhala, nogqinsi lwesendlalelo, ubungozi bokuvuza kwesignali ngenxa yokufakwa okungalungile kungancishiswa kakhulu. Finyelela amanani we-impedance anembile futhi angaguquki ngesibali se-impedance kanye nemithetho yokuklama enikezwe isoftware yokukhiqiza ye-PCB.

3. Ugqinsi lwesendlalelo se-insulation kwanele:

Ugqinsi lwesendlalelo sokuhlukanisa phakathi kwezendlalelo zethusi eziseduze ludlala indima ebalulekile ekuvimbeleni ukuvuza kanye nokuthuthukisa ukusebenza kokuhlanganisa kukonke. Imihlahlandlela yedizayini incoma ukuthi kugcinwe ukujiya okuncane kokufakwa ukuze kunqandwe ukuwohloka kukagesi. Kubalulekile ukulinganisa ukujiya ukuze kuhlangatshezwane nezidingo zokufakelwa ngaphandle kokuthikameze kabi ukushuba okuphelele nokuguquguquka kwe-PCB.

4. Ukuqondanisa nokubhaliswa okufanele:

Ngesikhathi se-lamination, ukuqondanisa okulungile nokubhaliswa phakathi kwezingqimba eziyinhloko kanye nezangaphambi kokulungiswa kufanele kuqinisekiswe. Ukungaqondi kahle kahle noma amaphutha okubhalisa angaholela ezikhala zomoya ezingalingani noma ukushuba kokufakwa kwe-insulation, kugcine kuphazamise ukusebenza kokufakwa kwe-interlayer. Ukusebenzisa amasistimu wokuqondanisa okuzenzakalelayo okuzenzakalelayo kungathuthukisa ngokuphawulekayo ukunemba nokuvumelana kwenqubo yakho yokucwasa.

5. Inqubo yokufakwa kwe-lamination elawulwayo:

Inqubo ye-lamination iyisinyathelo esibalulekile ekukhiqizeni i-PCB enezingqimba eziningi, okuthinta ngokuqondile ukusebenza kokufakwa kwe-interlayer. Imingcele yokulawula inqubo eqinile njengokucindezela, izinga lokushisa kanye nesikhathi kufanele kusetshenziswe ukuze kuzuzwe ukwahlukanisa okufanayo nokuthembekile kuzo zonke izendlalelo. Ukuqapha njalo nokuqinisekisa inqubo ye-lamination kuqinisekisa ukuhambisana kwekhwalithi yokufakelwa kuyo yonke inqubo yokukhiqiza.

6. Ukuhlola nokuhlola:

Ukuqinisekisa ukuthi ukusebenza kokufakwa kwe-interlayer kwama-PCB anezingqimba eziningi kuhlangabezana nezindinganiso ezidingekayo, ukuhlolwa okuqinile nezinqubo zokuhlola kufanele zisetshenziswe. Ukusebenza kwe-insulation ngokuvamile kuhlolwa kusetshenziswa ukuhlolwa kwamandla kagesi aphezulu, izilinganiso zokumelana nokufakwa kwe-insulation, nokuhlola umjikelezo oshisayo. Noma yimaphi amabhodi anesici noma izendlalelo kufanele zihlonzwe futhi zilungiswe ngaphambi kokucubungula okwengeziwe noma ukuthunyelwa.

Ngokugxila kulezi zici ezibucayi, abaklami nabakhiqizi bangaqinisekisa ukuthi ukusebenza kwe-interlayer insulation yama-PCB amaningi ahlangabezana nezidingo ezidingekayo. Ukutshala isikhathi nezinsiza ekukhetheni izinto ezifanele, idizayini ye-impedance elawulwayo, ukushuba okwanele kokufakwa, ukuqondanisa okunembayo, i-lamination elawulwayo, nokuhlolwa okuqinile kuzoholela ku-PCB enezingqimba eziningi ethembekile, esebenza kahle kakhulu.

Ngokufigqiwe

Ukuzuza ukusebenza kahle kokufakwa kwe-interlayer kubalulekile ekusebenzeni okuthembekile kwama-PCB anezingqimba eziningi kumishini kagesi. Ukusebenzisa amasu namasu okuxoxwe ngawo ngesikhathi sokuklama kanye nenqubo yokukhiqiza kuzosiza ukunciphisa ukuphazamiseka kwesignali, i-crosstalk, kanye nokwehluleka okungenzeka. Khumbula, ukwahlukanisa okufanele kuyisisekelo somklamo we-PCB osebenza kahle, oqinile.
