Kwibhodi yekopi ye-pcb, ukungakhathali okuncinci kunokubangela ukuba ipleyiti engezantsi ikhubazeke. Ukuba ayiphuculwanga, iya kuchaphazela umgangatho kunye nokusebenza kwebhodi yekopi ye-pcb. Ukuba ilahlwa ngokuthe ngqo, iya kubangela ilahleko yeendleko. Nazi ezinye iindlela zokulungisa i-deformation ye-plate ephantsi.
01Ukuqhawula
Kwimizobo enemigca elula, ububanzi bemigca emikhulu kunye nezithuba, kunye nokukhubazeka okungaqhelekanga, sike inxalenye ekhubazekileyo yefilimu engalunganga, uphinde uyidibanise ngokuchasene neendawo zomngxuma webhodi yokuvavanya, uze uyikopishe. Kunjalo, oku yeyemigca egogekileyo Lula, ububanzi belayini enkulu kunye nesithuba, imizobo egogekileyo; ayilungelanga iinegatives ezinoxinaniso oluphezulu lwecingo kunye nobubanzi bomgca kunye nesithuba esingaphantsi kwe-0.2mm. Xa udibanisa, kufuneka uhlawule kancinci kangangoko ukonakalisa iingcingo kwaye kungekhona iipads. Xa uhlaziywa inguqulelo emva kokudibanisa kunye nokukopisha, nikela ingqalelo ekuchanekeni kobudlelwane boxhulumaniso. Le ndlela ifanelekile kwifilimu engaxutywanga kakhulu kwaye ukuguqulwa koluhlu ngalunye lwefilimu aluhambelani, kwaye lusebenza ngokukodwa ukulungiswa kwefilimu ye-mask ye-solder kunye nefilimu yombane wombane webhodi ye-multilayer. .
02PCB ikopi ibhodi utshintsho umngxuma isikhundla indlela
Phantsi kobume bobuchule bokusebenza kwesixhobo sokucwangcisa idijithali, kuqala uthelekise ifilimu engalunganga kunye nebhodi yovavanyo lokomba, ulinganise kwaye urekhode ubude nobubanzi bebhodi yovavanyo lokomba ngokulandelelana, kwaye ke kwisixhobo sokucwangcisa idijithali, ngokutsho kwayo. ubude kunye nobubanzi ezimbini Ubungakanani deformation, lungisa indawo umngxuma, kwaye ulungelelanise ibhodi yokuvavanya ukomba oluhlengahlengisiweyo ukuhlangabezana negative ekhubazekileyo. Inzuzo yale ndlela kukuba iphelisa umsebenzi onzima wokuhlela izinto ezimbi, kwaye inokuqinisekisa ukuthembeka kunye nokuchaneka kwemizobo. Ukungalungi kukuba ukulungiswa kwefilimu engalunganga kunye ne-deformation yendawo enzulu kakhulu kunye ne-deformation engalinganiyo ayilungile. Ukusebenzisa le ndlela, kufuneka uqale ulawule ukusebenza kwesixhobo sokwenza inkqubo yedijithali. Emva kokuba isixhobo seprogram sisetyenziselwa ukwandisa okanye ukunciphisa indawo yomngxuma, indawo yokuphuma ngaphandle kokunyamezela kufuneka isetyenziswe kwakhona ukuqinisekisa ukuchaneka. Le ndlela ifanelekile ukulungiswa kwefilimu kunye nemigca edibeneyo okanye i-deformation deformation yefilimu.
03Indlela yokudibana komhlaba
Yandisa imingxuma kwibhodi yovavanyo kwiipads ukuze zigqithe kwaye uguqule isiqwenga sesekethe ukuze uqinisekise ubuncinci beemfuno zobugcisa zeringi. Emva kokuba ikopi edibeneyo, i-pad i-elliptical, kwaye emva kwekopi edibeneyo, umda womgca kunye nediski iya kuba yi-halo kunye ne-deformed. Ukuba umsebenzisi uneemfuno ezingqongqo kakhulu kwinkangeleko yebhodi yePCB, nceda uyisebenzise ngononophelo. Le ndlela ifanelekile kwifilimu enobubanzi bomgca kunye nesithuba esingaphezu kwe-0.30mm kwaye imigca yepateni ayixinene kakhulu.
04Ukufota
Sebenzisa nje ikhamera ukwandisa okanye ukunciphisa imizobo engalunganga. Ngokubanzi, ilahleko yefilimu iphezulu kakhulu, kwaye kuyafuneka ukulungisa impazamo ngamaxesha amaninzi ukufumana ipateni yesekethe eyanelisayo. Xa uthatha imifanekiso, ugxininiso kufuneka luchanekile ukuthintela ukugqwethwa kwemigca. Le ndlela ifanelekile kuphela kwifilimu yetyuwa yesilivere, kwaye ingasetyenziselwa xa kungenakulungeleka ukubhola ibhodi yokuvavanya kwakhona kunye nomlinganiselo we-deformation kwiindlela zobude kunye nobubanzi befilimu efanayo.
05Indlela yokuxhoma
Ngenxa yesiganeko somzimba ukuba ifilimu engalunganga iyatshintsha kunye nobushushu bendalo kunye nomswakama, thabatha ifilimu engafanelekanga kwisikhwama esitywiniweyo ngaphambi kokuba uyikopishe, kwaye uyixhome iiyure ezingama-4-8 phantsi kweemeko zendalo yokusebenza, ukwenzela ukuba ifilimu engafanelekanga ibe ikhubazekile phambi kokukopa. Emva kokukopa, ithuba lokuguqulwa lincinci kakhulu.
Kwii-negatives esele zikhubazekile, kufuneka kuthathwe amanye amanyathelo. Ngenxa yokuba ifilimu engalunganga iya kutshintsha kunye nokutshintsha kobushushu bendalo kunye nomswakama, xa uxhoma ifilimu engafanelekanga, qiniseka ukuba umswakama kunye nobushushu bendawo yokomisa kunye nendawo yokusebenza iyafana, kwaye kufuneka ibe kwindawo enomoya kunye nobumnyama. ukuthintela ifilimu engalunganga ukuba ingcoliseke. Le ndlela ifanelekile kwii-negatives ezingaguqukiyo kwaye inokuthintela izinto ezingalunganga ukuba zingahambi emva kokuba zikhutshelwe.
