Geedi socodka PCB habaynta, laga bilaabo substrate PCB ilaa wareejinta hannaankii wareegga gudaha iyada oo loo marayo dhowr jeer oo la cadaadiyo ilaa inta laga wareejinayo hannaanka wareegga dibadda, diiqada iyo dunta looxa ayaa balaadhi doona oo u yaraan doona jihooyin kala duwan. Laga soo bilaabo shaxda socodka-soo-saarka PCB-ga oo dhan, waxaan ka ogaan karnaa sababaha iyo nidaamyada sababi kara ballaarinta aan caadiga ahayn iyo hoos u dhaca qaybaha guddiga iyo joogteynta cabbirka liita:

Degganaanshaha cabbirka ee PCB substrate -ka, gaar ahaan joogtaynta cabbirka u dhexeeya mid kasta oo dahaadhaya CYCLE ee alaab -qeybiyaha. In kasta oo xasilloonida cabbirka substrate-ka PCB ee wareegyada kala duwan ee isla qeexitaannada ay dhammaantood ku jiraan shuruudaha qeexitaanka, joogtaynta liidata ee u dhaxaysa ayaa laga yaabaa inay keento dulqaad-ka-baxa cabbirka garaafka ee soo-saarka dufcadda dambe ee PCB sababtoo ah farqiga u dhexeeya dufcado kala duwan oo ka mid ah guddiga ka dib magdhowga lakabka gudaha ee macquulka ah waxaa lagu go’aamiyaa soosaarka tijaabada ee guddiga koowaad. Isla mar ahaantaana, waxaa sidoo kale jira cillad maaddo ah oo ku jirta geeddi-socodka garaafyada dibedda ee u wareejinta qaabka dhimista saxanka. Habka wax-soo-saarka, waxaa la ogaaday in ballaca guddiga iyo dhererka qaybta gaarsiinta ay si xun u xumaadeen saamiga wareejinta sawirada dibadda, oo gaaraya 3.6mil / 10inch. Baaritaanka ka dib, cabbiraadda raajada iyo saamiga wareejinta garaafyada dibadda ee dufcaddii aan caadiga ahayn ee taarikada ka dib lakabka cadaadiska dibadda ayaa labaduba ku jira xadka xakamaynta. Waqtigan xaadirka ah, hab ka wanaagsan oo la socodka ayaan laga helin la socodka habka.

Naqshadeynta guddida caadiga ahi waa mid simmetrical ah oo aan wax saamayn ah ku lahayn cabbirka garaafka ee PCB-ga la dhammeeyey iyadoo loo eegayo xaaladda saamiga wareejinta garaafyada caadiga ah. Si kastaba ha ahaatee, si loo hagaajiyo heerka isticmaalka ee guddiga oo loo yareeyo kharashka, qayb ka mid ah guddiga ayaa isticmaala naqshadeynta qaab-dhismeedka asymmetric, taas oo keeni doonta saameyn aad u muuqda oo ku saabsan joogteynta sawirada iyo cabbirka PCB-ga la dhammeeyey ee qaybinta kala duwan. meelaha. Xataa in habka of processing PCB, waxaan ka heli kartaa in lays sida design asymmetric ee guddiga waa ka adag tahay in la xakameeyo oo la hagaajiyo marka loo eego guddiga caadiga ah ee link kasta ee habka laysarka dalool dalool indha la’aan iyo soo-gaadhista garaafyada dibadda / alxanka. iska caabin soo-gaadhista/daabacaadda dabeecadda.

Qodobbada habka wareejinta garaafka lakabka gudaha Habka wareejinta garaafka lakabka gudaha ayaa door muhiim ah ka ciyaara in cabbirka guddiga PCB-ga la dhammeeyay uu buuxiyo shuruudaha macaamiisha. Haddii ay jirto leexasho weyn oo ku saabsan magdhowga saamiga filimka ee lagu bixiyo wareejinta sawirada lakabka gudaha, ma aha oo kaliya inay si toos ah u horseedi karto cabbirka sawirada PCB ee la dhammeeyey oo aan awoodin in la buuxiyo shuruudaha macaamiisha, laakiin sidoo kale waxay keenaysaa isku-dhafka aan caadiga ahayn ee u dhexeeya indhoolaha laser. daloolka iyo saxanka isku xirka hoose Si aad u keento waxqabadka dahaarka ee lakabka-lakabka Si aad hoos u dhigto iyo xitaa wareegga gaaban. Iyo dhibaatada toosinta godka indha la’aanta ee habka wareejinta sawirada dibadda.

Marka loo eego falanqaynta kor ku xusan, waxaan qaadi karnaa tallaabooyin ku habboon si aan ula soconno oo loo hagaajiyo kuwa aan caadiga ahayn;

La socoshada xasilloonida cabbirka ee PCB substrate-ka soo galaya iyo joogtaynta cabbirka u dhexeeya dufcadaha Deggenaanshaha cabbirka ee PCB substrate-ka ay bixiyeen alaab-qeybiyeyaasha kala duwan ayaa si joogto ah loo tijaabiyaa, taas oo laga soocayo farqiga xogta loolka-loolka u dhexeeya dufanno kala duwan oo ka mid ah guddiga qeexidda xogta imtixaanka ee PCB substrate waxaa lagu falanqeyn karaa farsamooyinka tirakoobka habboon. Sidan, alaab-qeybiyeyaal leh tayo xasiloon ayaa lagu heli karaa, iyo xogta xulashada alaab-qeybiyaha oo faahfaahsan ayaa la siin karaa SQE iyo waaxda wax iibsiga. Sida balaarinta ba’an iyo foosha ee qaybaha guddiga ka dib wareejinta garaafyada dibadda ay sababto xasilloonida cabbirka liidata ee substrate PCB ee dufcadaha shaqsiga, waxaa kaliya oo laga heli karaa iyada oo loo marayo cabbirka guddiga ugu horreeya ee wax soo saarka qaabka ama kormeerka shixnadaha. . Si kastaba ha noqotee, kan dambe wuxuu leeyahay shuruudo sare oo loogu talagalay maaraynta dufcadaha, wayna fududahay in la arko saxan isku dhafan marka tiro cayiman la soo saaro tiro badan.

Naqshadaynta qaab-dhismeedka summeedka waa in la qaataa ilaa inta suurtogalka ah si balaadhinta iyo foosha unug kasta oo shixnad ah oo ku jira sabuuradda jigsaw ay u ahaato mid joogto ah. Haddii ay suurtagal tahay, macmiilka waa in lagula taliyaa inuu oggolaado aqoonsiga gaarka ah ee goobta qayb kasta oo shixnad oo ku taal guddiga iyada oo la dhejinayo/aqoonsiga xarfaha cidhifka nidaamka ee looxa. Habkani habka saamaynta design asymmetric waa ka cad in guddiga, xitaa haddii kasta oo qurxiyo gudaha garaafyada asymmetrical sababa size unit shaqsi ka baxsan-dulqaadka, xitaa keeni kartaa in dalool indho la’aan hoose xiriir hoose ka reeban noqon kartaa mid aad u habboon in la go’aamiyo aan caadi ahayn. unug oo gacanta si aad u soo qaadato ka hor inta aan la rarin, ma aha qulqulka ay sababto xirid aan caadi ahayn oo keentey cabasho.

3. Samee taranka ugu horreeya, si cilmiyeysan u go’aamiya isku -dhufashada lakabyada gudaha ee wareejinta saxanka ugu horreeya, si cilmiyeysan u go’aamiya isku dhufashada garaafyada lakabka gudaha ee saxanka wax -soo -saarka iyada oo loo marayo saxanka koowaad; Tani waxay si gaar ah muhiim u tahay marka laga bedelayo substrate -ka PCB ama xaashiyaha P ee alaab -qeybiyeyaasha kale si loo yareeyo kharashaadka wax -soo -saarka. Marka la ogaado in saxanku ka baxsan yahay xakamaynta xakamaynta, waa in laga baaraandegaa iyada oo loo eegayo in daloolka tuubada unuggu yahay qodis labaad. Haddii ay tahay geedi socod wax qabad oo caadi ah, saxanka waxaa loo sii dayn karaa lakabka dibedda sida waafaqsan xaaladda dhabta ah waxaana loo wareejin karaa saamiga filimka si loo habeeyo habboon; Marka la eego taarikada sare ee la qoday, taxadar gaar ah waa in lagu sameeyaa daaweynta taarikada aan caadiga ahayn si loo hubiyo cabbirka garaafka ee taarikada la dhammeeyey iyo masaafada u jirta bartilmaameedka ilaa godka tuubada (godadka labaad ee la qoday); Waxa ku lifaaqan liiska saamiga ugu horreeya ee ururinta saxanka ee taarikada sare. 4. La soco habka samaynta guddiga PCB adiga oo isticmaalaya xogta bartilmaameedka gudaha ee taarikada dibadda ama hoose ee lagu cabbiray inta lagu guda jiro wax soo saarka raajada ee godad godad godad godad ka dib si loo falanqeeyo haddii ay ku jirto xadka gacanta iyo barbar dhig u dhigma. xogta ay soo ururiyeen taariko hore oo aqoon u leh si ay u qiimeeyaan in cabbirka taarikada uu yahay mid aan caadi ahayn marka loo eego ballaarinta iyo foosha; Marka loo eego xisaabinta aragtiyeed, isku-dhufashada halkan waa in lagu xakameeyaa gudaha +/- 0.025% si loo buuxiyo shuruudaha cabbirka ee taargooyinka caadiga ah.

Marka la falanqeeyo sababaha balaadhinta cabbirka PCB-ga iyo foosha, waxaan ogaan karnaa hababka la socodka iyo hagaajinta ee la heli karo, anagoo rajaynayna in badi dhakhaatiirta PCB ay arrintan ka heli karaan dhiirigelin, oo ay helaan qorshaha hagaajinta ee ku habboon shirkadahooda si waafaqsan tooda dhabta ah. xaalad.
