Embonini ye-elekthronikhi, amabhodi esekethe e-PCB anezingqimba eziningi abe ingxenye eyinhloko yamadivayisi amaningi kagesi asezingeni eliphezulu anezakhiwo zawo ezididiyelwe kakhulu neziyinkimbinkimbi. Kodwa-ke, ukwakheka kwayo okunezingqimba eziningi nakho kuletha uchungechunge lwezinselelo zokuhlola nokuhlaziya.
1. Izici ze-multi-layer PCB circuit board structure
Amabhodi wesekethe we-Multilayer PCB ngokuvamile akhiwa izendlalelo eziningi ezishintshayo ezishintshayo nezifaka insulating, futhi izakhiwo zazo ziyinkimbinkimbi futhi ziminyene. Lesi sakhiwo esinezendlalelo eziningi sinezici ezilandelayo ezibalulekile:
Ukuhlanganiswa okuphezulu: Ikwazi ukuhlanganisa inani elikhulu lezingxenye ze-elekthronikhi namasekethe endaweni elinganiselwe ukuze kuhlangatshezwane nezidingo zemishini yesimanje ye-elekthronikhi yokwenza i-miniaturization nokusebenza okuphezulu.
Ukudluliswa kwesignali okuzinzile: Ngokuklama izintambo ezifanele, ukuphazamiseka kwesignali nomsindo kungancishiswa, futhi ikhwalithi nokuzinza kokudluliswa kwesignali kungathuthukiswa.
Ukusebenza okuhle kokukhipha ukushisa: Isakhiwo esinezingqimba eziningi singahlakaza kangcono ukushisa, sinciphise izinga lokushisa lokusebenza kwezingxenye ze-elekthronikhi, futhi sithuthukise ukwethembeka nokuphila kwezinto zokusebenza.
2. Ukubaluleka kokuhlolwa kwesakhiwo sezendlalelo eziningi zamabhodi esekethe e-PCB anezingqimba eziningi
Qinisekisa ikhwalithi yomkhiqizo: Ngokuhlola uhlaka olunezingqimba eziningi zamabhodi wesekethe we-PCB anezingqimba eziningi, izinkinga zekhwalithi ezingaba khona, njengamasekhethi amafushane, amasekhethi avulekile, ukuxhumana okungekuhle kwe-inter-layer, njll., kungatholwa ngesikhathi, ngaleyo ndlela kuqinisekiswe ikhwalithi yomkhiqizo. kanye nokwethembeka.
Isixazululo sedizayini esilungiselelwe: Imiphumela yokuhlolwa inganikeza impendulo yokuklama kwebhodi lesifunda, isize abaklami balungiselele ukwakheka kwezintambo, bakhethe izinto ezisetshenziswayo nezinqubo ezifanele, futhi bathuthukise ukusebenza kwebhodi lesifunda kanye nokwenza.
Yehlisa izindleko zokukhiqiza: Ukuhlola okusebenzayo ngesikhathi senqubo yokukhiqiza kunganciphisa izinga le-scrap kanye nenani lokusetshenzwa kabusha, kunciphise izindleko zokukhiqiza, futhi kuthuthukise ukusebenza kahle kokukhiqiza.
3. Indlela yokuhlola yesakhiwo se-PCB enezingqimba eziningi
Ukuhlolwa kokusebenza kukagesi
Ukuhlolwa kokuqhubeka: Hlola ukuqhubeka phakathi kwemigqa ehlukahlukene ebhodini lesifunda ukuze uqiniseke ukuthi awekho amasekhethi amafushane noma amasekhethi avuliwe. Ungasebenzisa ama-multimeter, abahloli bokuqhubeka nezinye izisetshenziswa zokuhlola.
Ukuhlolwa kokumelana ne-insulation: Linganisa ukumelana nokufakwa kwe-insulation phakathi kwezingqimba ezihlukene ebhodini lesifunda naphakathi komugqa nomhlabathi ukuze unqume ukuthi ukusebenza kwe-insulation kuhle yini. Imvamisa ihlolwa kusetshenziswa isihloli sokumelana ne-insulation.
Ukuhlolwa kobuqotho besignali: Ngokuhlola amasignali anesivinini esiphezulu ebhodini lesifunda, ukuhlaziya ikhwalithi yokudlulisela, ukubonakaliswa, i-crosstalk neminye imingcele yesiginali ukuze kuqinisekiswe ubuqotho besiginali. Izisetshenziswa ezifana ne-oscilloscopes nezihlaziyi zesignali zingasetshenziselwa ukuhlola.
Ukuhlolwa kwesakhiwo somzimba
Isilinganiso sobukhulu be-Interlayer: Sebenzisa okokusebenza okufana nethuluzi lokulinganisa ukujiya ukuze ulinganise ukujiya phakathi kwesendlalelo ngasinye sebhodi lesifunda le-PCB elinezingqimba eziningi ukuze uqinisekise ukuthi lihlangabezana nezidingo zedizayini.
Isilinganiso sobubanzi bembobo: Hlola ububanzi bokubhola kanye nokunemba kwendawo ebhodini lesifunda ukuze uqinisekise ukufakwa okuthembekile nokuxhumeka kwezingxenye ze-elekthronikhi. Lokhu kungahlolwa kusetshenziswa i-boremeter.
Ukuhlolwa kokucaba komhlaba: Sebenzisa ithuluzi lokulinganisa ubucaba nezinye izisetshenziswa ukuze uthole ukucaba kwendawo yebhodi lesekethe ukuze uvimbele indawo engalingani ukuthi ithinte ikhwalithi yokushisela neyokufakwa kwezingxenye ze-elekthronikhi.
Ukuhlolwa kokwethembeka
Ukuhlolwa kokushaqeka kwe-thermal: Ibhodi lesifunda lifakwa ezindaweni zokushisa eziphakeme neziphansi futhi lijikelezwe ngokushintshana, futhi ukusebenza kwalo kuyashintsha phakathi nezinguquko zokushisa kuyabhekwa ukuze kuhlolwe ukwethembeka kwalo nokumelana nokushisa.
Ukuhlolwa kokudlidliza: Yenza ukuhlolwa kokudlidliza ebhodini lesekethe ukuze ulingise izimo zokudlidliza endaweni yokusetshenziswa yangempela futhi uhlole ukwethembeka kokuxhumeka kwalo nokuzinza kokusebenza ngaphansi kwezimo zokudlidliza.
Ukuhlolwa kwe-hot flash: Beka ibhodi lesekhethi endaweni enomswakama kanye nezinga lokushisa eliphezulu ukuze uhlole ukusebenza kwayo kokushisa nokumelana nokugqwala endaweni eshisayo.
4. Ukuhlaziywa kwesakhiwo se-multilayer PCB yebhodi lesifunda
Ukuhlaziywa kobuqotho besignali
Ngokuhlaziya imiphumela yokuhlolwa kobuqotho besignali, singaqonda ukudluliswa kwesignali ebhodini lesifunda, sithole izimbangela zokubonisa isignali, i-crosstalk nezinye izinkinga, futhi sithathe izinyathelo ezihambisanayo zokuthuthukisa. Isibonelo, ungalungisa ukwakheka kwezintambo, ukwandise ukumelana nokunqanyulwa, sebenzisa izinyathelo zokuvikela, njll. ukuze uthuthukise ikhwalithi nokuzinza kwesignali.
ukuhlaziya okushisayo
Usebenzisa isofthiwe yokuhlaziya okushisayo ukuze uhlaziye ukusebenza kokukhishwa kokushisa kwamabhodi esekethe e-PCB anezendlalelo eziningi, ungakwazi ukunquma ukusatshalaliswa kwezindawo ezishisayo ebhodini lesifunda, uthuthukise idizayini yokukhipha ukushisa, futhi uthuthukise ukwethembeka nempilo yebhodi lesifunda. Isibonelo, ungakwazi ukwengeza amasinki okushisa, ulungise ukuhlelwa kwezingxenye ze-elekthronikhi, ukhethe izinto ezinezici ezingcono zokushisa ukushisa, njll.
ukuhlaziya ukwethembeka
Ngokusekelwe emiphumeleni yokuhlolwa yokwethembeka, ukwethembeka kwebhodi lesifunda le-PCB elinezingqimba eziningi kuyahlolwa, izindlela zokuhluleka ezingaba khona kanye nezixhumanisi ezibuthakathaka ziyatholwa, futhi kuthathwa izinyathelo zokuthuthukisa ezihambisanayo. Isibonelo, ukwakheka kwesakhiwo samabhodi wesifunda kungaqiniswa, ikhwalithi nokumelana nokugqwala kwezinto kungathuthukiswa, futhi inqubo yokukhiqiza ingathuthukiswa.
Ukuhlolwa kwesakhiwo esinezingqimba eziningi kanye nokuhlaziywa kwamabhodi esekethe e-PCB anezingqimba eziningi kuyisinyathelo esibalulekile sokuqinisekisa ikhwalithi nokuthembeka kwemishini kagesi. Ngokusebenzisa izindlela zokuhlola eziphumelelayo nezindlela zokuhlaziya, izinkinga eziphakama ngesikhathi sokuklama, ukukhiqizwa kanye nokusetshenziswa kwamabhodi esekethe zingatholwa futhi zixazululwe ngesikhathi, ukuthuthukisa ukusebenza nokukhiqizwa kwamabhodi esekethe, ukunciphisa izindleko zokukhiqiza, nokuhlinzeka ngokusekela okuqinile ukuthuthukiswa kwemboni yezogesi. ukusekela.
