1. Waa markii ugu horeysay ee aan awoodno inaan tan sameyno. 2

PCB habka dahaadhay

1. Makiinada cadaadiska ee Autoclave

Laminates waa weel ay ka buuxaan heerkul sarreeya oo uumiga biyaha ka buuxo, wuxuuna saari karaa cadaadis sare, wuxuu dhejiyaa muunada, oo lagu dhex ridaa in muddo ah, biyaha lagu qasbo saxanka, ka dibna wuxuu soo saaraa saxanka oo la saaraa dusha sare ee Daasad dhalaalaysa heer-kulka sare, cabbiraadda sifooyinka “iska caabinta lamination”. Eraygani waxa uu leeyahay magac kale oo la mid ah Makiinada Culayska waxaana caadi ahaan loo adeegsadaa warshadaha. Intaa waxaa dheer, waxaa jira nooc ka mid ah “habka cadaadiska qolka” oo lagu sameeyay heerkulka sare iyo cadaadiska sare ee kaarboon dioxide ee habka lamination, kaas oo sidoo kale iska leh nooca Autoclave Press.

2. Kabka Lamination

“Lakabka sare” ee MLB waa la dahaadhay oo lagu riixay substrates maqaar ah oo khafiif ah oo hal dhinac ah. Ma ahayn ilaa dhamaadkii 1984-kii, markii wax soo saarka MLB uu si aad ah u kordhay, in habka hadda jira ee maqaar-maqaar-weyn ama bulk lamination (Mss Lam) la qaatay. Cadaadiskan hore ee MLB iyadoo la adeegsanayo hal maqaar oo khafiif ah oo naxaas ah ayaa loo yaqaan Cap LaminaTion.

3. Caul Plate

Marka saxanadda lakabka badan la riixo, inta u dhaxaysa Furitaanka sariirta sariirta (Furitaanka), inta badan waxaa lagu dhejiyaa “buugaagta” badan si loo riixo walxo dabacsan (sida 8 ~ 10), inta u dhaxaysa qayb kasta oo ah “wax dabacsan” (Buug) , waa in lagu kala saaraa saxan bir ah oo siman oo adag, Muraayada noocaan ah ee aan birta lahayn waxaa loo yaqaanaa Caul Plate ama Plate gooni ah. AISI 430 ama AISI 630 ayaa inta badan la isticmaalaa hadda.

4. Crease

Cadaadiska laminate-ka, inta badan waxaa loola jeedaa maqaarka naxaasta ee ka shaqeynta burooyinka. Maqaar khafiif ah oo naxaas ah oo ka yar 0.5 oz ayaa aad ugu nugul cilladan marka lagu cadaadiyo lakabyo badan.

5. Diid

Waxay tilmaamaysaa dabacsanaanta iyo xitaa hoos-u-dhaca dusha naxaasta ah, kaas oo laga yaabo inay sababto soo-baxa baruurta leh ee saxanka birta ee loo isticmaalo cadaadiska. Haddii cidhifka saxanku uu si nadiif ah u dhaco si qalad ah, waxa loo yaqaan Dish Down. Cilladahan, haddii nasiib darro looga tago khadka ka dib markii naxaasta lagu dhejiyo, waxay sababi doontaa xasillooni darrada xawaaraha sare ee signalka gudbinta, iyo buuqa. Sidaa darteed, dusha sare ee naxaasta ee substrate-ka waa in laga fogaadaa sida ugu macquulsan.

6. Foil LaminaTion

Waxa loola jeedaa guddiga multilayer wax soo saarka Mass, lakabka sare ee kaas oo lagu riixo bireed naxaas ah iyo filim si toos ah iyo lakabka gudaha ee loo yaqaan Mass Lam guddiga multilayer, beddelaya habka dhaqanka ee substrate hal khafiif ah marxaladda hore.

7. Cadaadiska dhunkashada

Marka looxa multilayer la riixo, marka taarikada ku yaal furitaanka kasta la dhigo oo la dhigo, waxay bilaabataa inay kor u kacdo oo kor uga qaaddo saxanka kulul ee hoose oo leh tiir sare oo biyo ah (Ram) si aad u riixdo alaabta dabacsan ee furitaanka kasta si loogu xiro . Waqtigaan oo lagu daray filimka (Prepreg) wuxuu bilaabay inuu si tartiib tartiib ah u jilciyo xitaa qulqulka, sidaas darteed cadaadiska loo isticmaalo extrusion sare ma noqon karo mid aad u weyn, si looga fogaado in saxan ama xabagta qulqulka aad u badan. Cadaadiskan hoose ee bilowga ah (15 ilaa 50 PSI) waxa loo yaqaan “cadaadis dhunkasho”. Laakiin marka xabagta ee alaabta bulk filimka waxaa jilciyey kulaylka iyo gelatinized, iyo adkaan doonaa, taas oo ah, si ay u kordhiyaan cadaadiska buuxa (300 ~ 500 PSI), si ay wax bulk ah si loo gaaro isku darka dhow iyo samaynta a guddi lakabyo badan oo adag.

8. Waraaqda Kraft

Warqadda Kraft waxaa loo isticmaalaa sidii kayd wareejinta kulaylka si loogu dhejiyo looxa lakabyo badan ama looxa substrate-ka. Waxaa la dhigaa inta u dhaxaysa saxanka kulul (Platern) ee saxaafadda iyo saxanka birta si loo dhexdhexaadiyo qalooca kuleyliyaha ee ugu dhow alaabta badan. Inta u dhaxaysa substrate badan ama taariko badan oo la cadaadiyo. Ilaa inta suurtogalka ah in la xiro farqiga heerkulka u dhexeeya lakabyada kala duwan ee saxanka, sifooyinka caadiga ah ee la isticmaalo waa 90 ilaa 150 rodol. Sababtoo ah heerkulka sare iyo cadaadiska sare, fiber-ka warqadda waa la jebiyey, hadda ma laha adkeysi iyo adag tahay in la ciyaaro door, markaa waa inaan isku daynaa inaan bedelno. This kraft paper is a mixture of pine and a variety of strong alkali boiled, after the volatiles escape and acid removal, then washed and precipitation; When it becomes pulp, it can be pressed again to become a rough and cheap paper.

9. Dhig

Ka hor inta aan la cadaadin laminate ama substrate, waxaa lagama maarmaan ah in la isku hagaajiyo, la dhaco, ama la dhigo lakabka gudaha, filimka, naxaasta iyo walxaha kale ee badan ee leh taarikada birta, qalabka waraaqaha kraft, iwm, si taxadar leh loogu quudiyo mashiinka riixaya ee cadaadis kulul. Diyaarinta noocaan ah waxaa loo yaqaannaa laying Up. Si loo hagaajiyo tayada guddiga multilayer, ma aha oo kaliya shaqadan “isku-dhafka ah” ee lagu sameeyo xakamaynta heerkulka iyo qoyaanka qolka boodhka, laakiin sidoo kale si loo kordhiyo xawaaraha wax soo saarka iyo tayada, guud ahaan siddeedda lakab ee soo socda. Waxaa la qaatay habka saxanka cadaadiska weyn (Mass Lam), oo xitaa u baahan yihiin in la isticmaalo habka “otomaatigga ah”, si loo yareeyo khaladaadka iyo khasaaraha aadanaha. Si loo badbaadiyo warshadda loona wadaago qalabka, warshadda guud waxay noqon doontaa mid aad u badan oo “isku-dhafan” iyo “boodhka laalaabida” labaduba waxay ku milmi doonaan unug farsamayneed oo dhammaystiran, sidaa darteed injineernimada otomaatiga ah waa mid aad u adag.

10. Mass LaminaTion (laminated)

Tani waa qaab dhismeed cusub oo ka tagaya “caarada toosinta” iyo qaadashada safaf badan oo taarikada ah oo isku mid ah. Laga soo bilaabo 1986, markii baahida afar iyo lix laminates kor u kacday, habka laminating multilaminates ayaa wax badan bedelay. Marxaladda hore, kaliya hal saxan oo shixnad ah ayaa lagu diyaariyey saxanka habsocodka si loo cadaadiyo. Habkan mid-mid ah waxa lagu jabiyay sharciga cusub, kaas oo loo bedeli karo laba-labo, ama afar afar ah, ama xitaa safaf badan oo taarikada ah oo la isku dhejiyo inta ay le’eg tahay. Midda labaad waa in la tirtiro dhammaan noocyada walxaha dabacsan (sida xaashida gudaha, filimka, xaashida dibadda, iwm.) ee caarada toosinta; The outer layer is changed to copper foil, and the “target” is pre-made on the inner layer plate, which is “swept” to get the target after pressing, and then the tool hole is drilled from the center, which can be set on the drilling machine for drilling. Sida lix ama siddeed lakab oo loox ah, filimka lakab kasta oo gudaha ah iyo sandwich waa la jeexjeexi karaa ka dibna lagu cadaadi karaa heerkulka sare. Waxa kale oo ay kordhin kartaa tirada “High” iyo Furitaanka si waafaqsan habka saxanka saldhigga. Ma yarayn karto oo kaliya shaqada iyo labanlaabida wax soo saarka, laakiin sidoo kale waxay fulisaa otomaatig ah. Habka platen ee fikradan cusub waxaa loo yaqaan “platelen weyn” ama “large platen”. Sanadihii la soo dhaafay, waxaa jiray ganacsiyo badan oo OEM ah oo riixaya Shiinaha.

11. Taarikada kulul ee Platen

Waa goob qaadis dhaqaaqi karta oo loogu talagalay mishiinka laminateerka lagu riixo ama saxanka salku soo saaro. Mesa bir ah oo bannaan oo ka mid ah baaxadda noocan oo kale ah, asal ahaan waa in la bixiyo cadaadiska iyo isha kulaylka looxa, sababtu waa inay weli sii wadi kartaa awoodda siman ee heerkulka sare si ay u tagto. Caadiyan saxan kasta oo kulul waxa uu ku dhex jiraa tuubada uumiga, tubbada kulul ama walxaha kulaylka iska caabinta, iyo cidhifka dibadda ee ku hareeraysan waa in sidoo kale lagu buuxiyaa walxo dahamiya, si loo yareeyo khasaaraha kulaylka, oo lagu qalabeeyo qalabka dareenka heerkulka si loo xakameeyo heerkulka.

12. Press Plate

Refers to the substrate or multilayer board in the pressing, used to separate each group of loose Book (refers to copper, film and inner layer of a Book, etc.). Saxan adag oo bir ah ayaa ah AISI 630 (adkeydka ilaa 420 VPN) ama AISI 440C (600 VPN) birta daawaha ah, dusha sare ma aha oo kaliya mid aad u adag, oo si taxadar leh loo iftiimiyay muraayadda, waxaa lagu cadaadin karaa substrate fidsan ama guddiga wareegga. . Sidaa darteed, waxaa sidoo kale loo yaqaannaa saxanka muraayadda, oo sidoo kale loo yaqaan ‘Carrier Plate’. Shuruudaha saxanka birta ah waa mid aad u adag, oogada sare waa inaysan u muuqan wax xoqan, jeexjeexyo ama dhejis ah, dhumucdiisu waa inay noqotaa mid isku mid ah, adkaanta waa inay ahaataa mid ku filan, waxayna u adkeysan kartaa etching kiimikaad ee ay soo saarto cadaadiska heerkulka sare. Qiimaha saxanka birta ah ee noocan oo kale ah waa mid aad qaali u ah sababtoo ah waxay awood u leedahay inay u adkeyso burushyada farsamada xooggan ka dib cadaadis kasta.

13. Ku daabac

Awoodda cadaadiska (PSI) ee loo isticmaalo marka saxanka la dhejiyay uu aad u weyn yahay, sidaas darteed resins badan ayaa laga soo saarayaa saxanka, taas oo keentay in maqaarka naxaasta ah si toos ah loogu cadaadiyo marada galaaska, xitaa marada dhalada ah ayaa la siman oo qallafsan, sidaas awgeed. in dhumucda saxanku aysan ku filneyn, xasilloonida cabbirka ayaa liidata, iyo xariiqda gudaha ayaa lagu cadaadiyaa qaabka iyo cilladaha kale. Xaalado halis ah, aasaaska siligga wuxuu inta badan xiriir toos ah la leeyahay marada faybarka galaaska, isagoo aasaya welwelka daadinta “Fiber galaas ConductTIve”. CAF). Xalka aasaasiga ah waa sida waafaqsan mabda’a qulqulka Miisaanka leh, riixitaanka aagga weyn waa inuu isticmaalo xoojinta cadaadiska weyn, dusha sare ee saxan yar oo isticmaala xoojinta cadaadiska yar; Cadaadiska iyo xoogga hawlgalka goobta waxaa lagu xisaabiyaa iyadoo la isticmaalayo 1.16PSI/in2 ama 1.16Lb/in4 sida gundhig ahaan.

14. Relamination (RE-LAM) saxan dahaadhay

Lakabka gudaha ee substrate khafiifka ah, wuxuu ka samaysan yahay alaab-qeybiyeyaal substrate iyadoo la adeegsanayo filim iyo naxaas la isku riixay, warshadda guddiga wareegga waxay iibsadeen substrate khafiif ah oo ka samaysan guddiga wareegga gudaha, laakiin sidoo kale filimka si loo cadaadiyo guddiga multilayer synthetic, mararka qaarkood ayaa inta badan xoogga la saarayaa oo loo yaqaan ” dib loo wada riixay”, oo loo yaqaan re-LAM. Dhab ahaantii, waa nooc ka mid ah “Draven” oo loogu talagalay alwaax dahaaran, oo aan macne kale lahayn.

15. Resin Recession, Resin Retreat

Saxanka Sandwich ee B – marxaladda filimka resin ama boodhka BoJi (sababta) ee hore, weli si buuxda uma adkaan karin ka dib markii la riixo (taas oo ah, la’aanta shahaadada polymerization), buuxi daloolka tiirka daasadaha, marka Baadhitaano, la ogaaday in gidaarka naxaasta ah ee godka ka dambeeya la’aanta resin polymerization gaar ah, ka soo muuqan doona gidaarka naxaasta dib u madhan, “subsidence resin” waxaa loola jeedaa. Ciladdan waa in loo kala saaraa sida dhibaatada guud ee habka ama saxanka, taas oo ka sii daran cilladaha farsamada ee xoqitaanka dusha sare, sababtana waa in si taxadar leh loo baadho.

16. Tijaabada socodka miisaanka

It is a method of detecting the amount of glue in the film (Prepreg) when the laminate is pressed.Sidoo kale waa hab tijaabo ah oo loogu talagalay qulqulka Resin ee heerkul sarreeya iyo cadaadis sare. Fiiri qaybta 2.3.18 ee IPC-TM-650 wax qabad faahfaahsan, oo arag PCB Information Journal, No. 14, P.42 si aad u hesho sharaxaad aragti iyo nuxur

17. Saxanka kala saara, saxan muraayadda

Marka saxanka salka ama saxanka badan la riixo, saxanka adag ee birta ah (410,420, iwm.) ee loo isticmaalo in lagu kala saaro Buugaag kasta oo furan (Iftiinka) ee saxaafadda. Si looga hortago adhesion, dusha sare ayaa si gaar ah loogu daaweeyaa inuu yahay mid aad u fidsan oo dhalaalaya, sidaas darteed waxaa sidoo kale loo yaqaannaa Plate Mirror.

18. Lamination isku xigxiga

Waxa ay tilmaamaysaa isku xidhka lakabyada looxa badan oo aan isku mar samayn balse isku mar isku mar ah qaab godadka indhoolaha ah ama la aasay. Habkani wuxuu badbaadin karaa dusha sare ee looxa waa in laga soo saaraa godka buuxa. Looxyo dheeraad ah ayaa la heli karaa si loo kordhiyo tirada fiilooyinka iyo SMDS, laakiin habka wax soo saarka ayaa dib u dhac weyn ku yimid.

19. Xabagta gaajada

Erayga ku jira warshadaha guddida wareegga, ayaa si caadi ah loo adeegsaday isku xidhka guddiyada badan ee “koollo la’aanta” muujinta dhibaatada gaajada. Waxa loola jeedaa qulqulka xabagta xun, ama xaaladaha cadaadis leh oo aan habboonayn, taasoo keentay dhamaystirka guddiga multilayer, jidhka saxanka ee xabag la’aanta maxalliga ah.

20. Xariiqda dabaasha ayaa simbiriirixday

Dabbaalku waxa loola jeedaa dhaq-dhaqaaq simbiriirixan oo ah lakabka gudaha ee looxa lakabyo badan inta lagu jiro cadaadis. Tani waxay si dhow ula xiriirtaa dhererka “Gel Time” ee filimka la isticmaalay. Waqtigan xaadirka ah, warshaduhu waxay u janjeersadeen inay isticmaalaan waqti gaaban oo Gel Time ah, sidaas darteed dhibaatada aad ayaa loo yareeyay.

21. Daabacaadda sabbaynaysa ee Telegraphing, daabacaadda qarsoon

Si looga hortago dhibaatada xabagta, filim kulaylka u adkaysta (sida Tedlar) ayaa lagu daraa foornada naxaasta ah ama saxanka khafiifka ah ee walxaha kala firidhsan ee la isku dhejiyay, si ay u fududaato isticmaalka xoqidda ama qallafsanaanta ka dib. cadaadisid. Si kastaba ha noqotee, marka filimka loo isticmaalo saxanka dibadda uu yahay mid khafiif ah oo foornada naxaasta ah ay tahay 0.5 oz oo keliya, qaabka wareegga ee saxanka gudaha ayaa laga yaabaa in loo wareejiyo warqadda sii deynta cadaadis sare. Marka warqadda duminaysa dib loogu isticmaalo looxyo, waxay u badan tahay inay ku dul sabbayso qaabka asalka ah ee dusha naxaasta ah ee looxa cusub, dhacdadan waxaa loo yaqaan Telegraphing.

22. Profile Heerkulka

In warshadaha guddiga wareegga ee geeddi-socodka riixaya, ama shirka hoose ee infrared ama hawo kulul alxanka (Dib-u-qulqulaya) habka, oo dhan waxay u baahan yihiin in la raadiyo heerkulka ( dhidibka toosan ) iyo waqtiga ( dhidibka horizontal) isku dhafka ah ee ugu wanaagsan “qallooca heerkulka”, si kor loogu qaado tayada alxanka ee heerka wax soo saarka tirada badan.

23. Vacuum Lamination

Eraygu wuxuu inta badan ka soo muuqdaa warshadaha PCB ee ku xidhidhiyaha aflaanta iyo qalalan. Cadaadiska Vacuum ee looxa multilayer wuxuu u qaybsan yahay Vacuum outer Frame (Vacuum Frame), kaas oo ah “habka bamgareynta” ee leh saxafada asalka ah ee haydarooliga, iyo qolka Vacuum (Autoclave), taas oo ah “habka cadaadiska” ee isticmaalka sare heerkulka iyo cadaadiska sare ee carbon dioxide. Cadaadiska Hydralic Vacuum Pressing ayaa ka badan 90% suuqa sababtoo ah qalabkiisa fudud, qiimo jaban iyo hawlgal ku habboon. Tan dambe waa sababta oo ah qalabka iyo hawlgalku aad bay u adag yihiin, muggana aad buu u weyn yahay, oo lagu daray kharashka saadka loo baahan yahay oo ka qaalisan, sidaa darteed korsashadu maaha mid badan.

24. Laalaab, Laalaab

Badanaa waxaa loola jeedaa cadaadiska marka qulqulka xabagta ay aad u weyn tahay. 11. Laalaabku waxa ay sababtaa laalaabkii, kaas oo sababa in lakabka sare uu xoogaa daciifo xoog iyo adayg ahaan, sida 0.5oz naxaas foil ah oo loo yaqaano Laalaab. Erayga waxaa sidoo kale loo isticmaalaa meelo kale.
