I-Multilayer PCB yakhiwe ngokuyinhloko nge-foil yethusi, ishidi eliphekwe kancane, ibhodi eliwumgogodla.Kunezinhlobo ezimbili zesakhiwo esilingana nokucindezelwa, okuyi-copper foil kanye ne-core board-fit structure kanye nebhodi eliwumgogodla kanye ne-core board-fit structure.I-foil yethusi ekhethwayo kanye nesakhiwo se-lamination esiyinhloko, amapuleti akhethekile (afana ne-Rogess44350, njll.) Ibhodi le-multilayer kanye nebhodi lesakhiwo somshini wokunyathelisa elixubile lingasetshenziswa isakhiwo esiyisisekelo sokuqothula.Qaphela ukuthi isakhiwo esicindezelwe (PCB Construction) kanye nomdwebo wokubhola wokulandelana kwebhodi elistakiwe (Izendlalelo zokupakisha) kuyimiqondo emibili ehlukene.Eyangaphambili ibhekisela ku-PCB ecindezelwe ndawonye lapho isakhiwo esistakiwe, esaziwa nangokuthi isakhiwo esistakiwe, lesi sakamuva sibhekisela kuhlelo lokupakisha lwe-PCB, olwaziwa nangokuthi i-oda lokupakisha.
1. Kucindezelwe ndawonye izidingo zomklamo wesakhiwo
Ukuze kuncishiswe ukwenzeka kwekhasi lempi le-PCB, i-PCB ecindezelwe ndawonye isakhiwo kufanele ihlangabezane nezidingo zokulinganisa, okungukuthi, ubukhulu befoyili yethusi, isigaba sesendlalelo semidiya nokuqina, uhlobo lokusatshalaliswa kwesithombe (ungqimba lomugqa, ungqimba lwendiza), sicindezelwe ndawonye isihlobo esilinganayo. enkabeni eqondile ye-PCB.
2. Ugqinsi lwethusi lwe-conductor
(1) ugqinsi lwethusi lwekhondatha oluphawulwe emidwebeni yogqinsi lwethusi oluqediwe, okungukuthi, ugqinsi lwethusi lwangaphandle logqinsi lwecwecwe lethusi elingaphansi kanye nogqinsi longqimba lokucwenga, ukujiya kwethusi kwangaphakathi kobukhulu bengaphakathi. ucwecwe lwethusi phansi.Ugqinsi lwethusi lwangaphandle emdwebeni luphawulwe ngokuthi “ugqinsi lwe-copper foil + plating, futhi ukujiya kwethusi kwangaphakathi kumakwe ngokuthi “ugqinsi lwe-foil yethusi”.
(2) I-2OZ nangaphezulu kokucatshangelwa kwesicelo sethusi esiphansi esiwugqinsi.
Kumele isetshenziswe ngokulinganayo kulo lonke uhlaka lwama-laminated.
Ukugwema ukubeka ungqimba lwe-L2 no-Ln-2 ngangokunokwenzeka, okungukuthi, Phezulu, Indawo ephansi yesendlalelo sangaphandle sesibili, ukuze ugweme ukungalingani kwe-PCB ebusweni, ukushwabana.
3. Izidingo zesakhiwo esicindezelwe
Inqubo yokucindezela iyinqubo eyisihluthulelo yokukhiqiza kwe-PCB, izikhathi eziningi izimbobo ezicindezelwe kanye nokunemba kokuqondanisa kwediski kuzoba kubi kakhulu, ukuguqulwa kwe-PCB okubucayi kakhulu, ikakhulukazi uma kucindezelwe i-asymmetric ndawonye.Izidingo zokucwangciswa kwe-lamination, njengokujiya kwethusi nokuqina kwemidiya kumele kuhambisane.
