Isicelo
Ake sethule ulwazi oluthile lwe-pcb yethusi ukujiya.
Icwecwe le-Copper njengomzimba oqhutshwayo we-pcb, ukunamathela kalula kungqimba lokufakwa ngaphakathi, iphethini yokugqwala yesekethe.Ugqinsi lwecwecwe lethusi zivezwa ngo-oz(oz), 1oz=1.4mil, futhi ukushuba okumaphakathi kwefoyili yethusi kuvezwa ngesisindo ngeyunithi ngayinye. indawo ngefomula: 1oz=28.35g/ FT2(FT2 yizinyawo eziyisikwele, unyawo-skwele olu-1 =0.09290304㎡).
International pcb zethusi ucwecwe evame ukusetshenziswa ukujiya: 17.5um, 35um, 50um, 70um. Ngokuvamile, amakhasimende awenzi amazwi akhethekile lapho enza i-pcb. Ugqinsi lwethusi lwezinhlangothi ezingashadile nezikabili ngokuvamile luyi-35um, okungukuthi, ithusi elingu-1 amp. Vele, amanye amabhodi aqondile azosebenzisa i-3OZ, 4OZ, 5OZ... 8OZ, njll., ngokuya ngezidingo zomkhiqizo ukukhetha ukujiya okufanele kwethusi.
Ugqinsi lwethusi olujwayelekile lwebhodi le-PCB eliseceleni elilodwa neliphindwe kabili licishe libe ngu-35um, kanti olunye ugqinsi lwethusi luyi-50um no-70um. Ugqinsi lwethusi olungaphezulu lwepuleti le-multilayer ngokuvamile luyi-35um, kanti ugqinsi lwethusi lwangaphakathi luyi-17.5um. Ukusetshenziswa Pcb ibhodi zethusi ukujiya ikakhulukazi incike ukusetshenziswa PCB kanye signal voltage, usayizi wamanje, 70% we ibhodi wesifunda isebenzisa 3535um ucwecwe yethusi ukujiya. Vele, ibhodi lesifunda lamanje likhulu kakhulu, ukujiya kwethusi kuzosetshenziswa 70um, 105um, 140um (okumbalwa kakhulu)
Ukusetshenziswa kwebhodi le-Pcb kuhlukile, ukusetshenziswa kokuqina kwethusi nakho kuhlukile. Njengemikhiqizo evamile yabathengi nezokuxhumana, sebenzisa i-0.5oz, 1oz, 2oz; Esikhathini esiningi samanje esikhulu, njengemikhiqizo yamandla kagesi aphezulu, ibhodi yokuphakela amandla neminye imikhiqizo, ngokuvamile kusetshenziswa ama-3oz noma ngaphezulu imikhiqizo yethusi ewugqinsi.
Inqubo ye-lamination yamabhodi wesifunda ngokuvamile imi kanje:
1. Ukulungiselela: Lungiselela umshini wokulahla kanye nezinto ezidingekayo (okuhlanganisa amabhodi wesifunda kanye nama-foil ethusi okuzokwenziwa i-laminated, amapuleti okucindezela, njll.).
2. Ukwelashwa kokuhlanza: Hlanza futhi ukhiphe i-deoxidize ingaphezulu lebhodi lesifunda kanye ne-copper foil ezocindezelwa ukuze kuqinisekiswe ukusebenza kahle kwe-soldering nokusebenza kokubopha.
3. Lamination: Laminate foil yethusi kanye nebhodi lesifunda ngokuvumelana nezidingo, ngokuvamile ungqimba olulodwa lwebhodi lesifunda kanye nongqimba olulodwa lwe-foil yethusi lupakishwa ngokushintshana, futhi ekugcineni kutholakala ibhodi lesifunda elinezingqimba eziningi.
4. Ukuma nokucindezela: faka ibhodi lesifunda elaminethiwe emshinini wokucindezela, bese ucindezela ibhodi lesifunda elinezingqimba eziningi ngokubeka ipuleti lokucindezela.
5. Inqubo yokucindezela: Ngaphansi kwesikhathi esinqunyiwe nokucindezela, ibhodi lesifunda kanye ne-foil yethusi kucindezela ndawonye ngomshini wokucindezela ukuze kuhlanganiswe ngokuqinile ndawonye.
6. Ukwelashwa kokupholisa: Beka ibhodi lesifunda elicindezelwe endaweni yokupholisa ukuze uthole ukwelashwa okupholisa, ukuze lifinyelele izinga lokushisa elizinzile kanye nesimo sokucindezela.
I-7.Ukucutshungulwa okulandelayo: Engeza izilondolozi ebusweni bebhodi lesifunda, wenze ukucubungula okulandelayo njengokumba, ukufaka iphini, njll., ukuqedela yonke inqubo yokukhiqiza yebhodi lesifunda.
Imibuzo Evame Ukubuzwa
Ugqinsi longqimba lwethusi olusetshenziswa ngokuvamile luncike kumanje odinga ukudlula ku-PCB. Ugqinsi lwethusi olujwayelekile lulinganiselwa ku-1.4 kuya ku-2.8 mils (1 kuya ku-2 oz)
Ubukhulu obuncane bekhopha be-PCB ku-laminate egqoke ithusi buzoba ngu-0.3 oz-0.5oz
I-PCB yogqinsi oluncane yigama elisetshenziselwa ukuchaza ukuthi ukushuba kwebhodi lesifunda eliphrintiwe lincane kakhulu kune-PCB evamile. Ubukhulu obujwayelekile bebhodi lesekethe okwamanje buyi-1.5mm. Ubukhulu obuncane bungu-0.2 mm kuningi lamabhodi esekethe.
Ezinye zezici ezibalulekile zihlanganisa: i-fire retardant, i-dielectric constant, factor yokulahlekelwa, amandla aqinile, amandla okugunda, izinga lokushisa lokushintsha kwengilazi, nokuthi bungakanani ugqinsi olushintshayo ngezinga lokushisa (i-coefficient ye-Z-axis yokwandisa).
Yinto ehlanganisayo ehlanganisa ama-cores aseduze, noma i-core nesendlalelo, kusitaki se-PCB. Imisebenzi eyisisekelo yama-prepregs ukuhlanganisa umongo komunye umgogodla, ukuhlanganisa umongo kungqimba, unikeze ukufakwa kwe-insulation, nokuvikela ibhodi lezendlalelo eziningi ekujikelezeni okufushane.
