Za
PCB apanga kuchokera wosanjikiza umodzi mpaka iwiri-mbali, Mipikisano wosanjikiza ndi kusinthasintha matabwa, ndipo mosalekeza kukula mu malangizo mwatsatanetsatane mkulu, kachulukidwe mkulu ndi kudalirika mkulu.Kuchepetsa kukula, kuchepetsa mtengo, komanso kuwongolera magwiridwe antchito kumapangitsa gulu losindikizidwa ladera kukhalabe lolimba pakupanga zinthu zamagetsi m'tsogolomu.M'tsogolomu, chitukuko cha makina osindikizira gulu kupanga gulu ndi kukhala molunjika kwa kachulukidwe mkulu, mwatsatanetsatane mkulu, kabowo kakang'ono, waya woonda, phula laling'ono, kudalirika mkulu, Mipikisano wosanjikiza, mkulu-liwiro kufala, kulemera kuwala ndi mawonekedwe owonda.
Tsatanetsatane wa njira zodzitetezera pakupanga kwa PCB
1. Kupanga
Ntchito yopangira isanayambe, PCB iyenera kupangidwa / kukonzedwa ndi wogwiritsa ntchito CAD kutengera dongosolo la dera logwira ntchito.Kachitidwe kamangidwe kakadzatha, zolemba zambiri zimaperekedwa kwa wopanga PCB.Mafayilo a Gerber akuphatikizidwa muzolemba, zomwe zimaphatikizapo kasinthidwe kagawo-ndi-wosanjikiza, mafayilo obowoleza, sankhani ndikuyika deta, ndi zolemba zolemba.Kukonza zipsera, kupereka malangizo processing zofunika kupanga, zonse PCB specifications, miyeso ndi kulolerana.
2. Kukonzekera musanayambe kupanga
Nyumba ya PCB ikalandira phukusi la fayilo la wopanga, akhoza kuyamba kupanga ndondomeko yopangira zinthu ndi phukusi lazojambula.Mafotokozedwe opangira amatsimikizira dongosololo polemba zinthu monga mtundu wa zinthu, kumaliza kwapamwamba, plating, gulu la mapanelo ogwirira ntchito, njira zopangira, ndi zina zambiri.Kuphatikiza apo, seti ya zojambulajambula zowoneka bwino zitha kupangidwa kudzera mwa wojambula filimu.Zojambulazo zidzaphatikizapo zigawo zonse za PCB komanso zojambulajambula za soldermask ndi chizindikiro cha mawu.
3. Kukonzekera zinthu
Mafotokozedwe a PCB omwe mlengi amafunikira amasankha mtundu wazinthu, makulidwe apakati ndi kulemera kwa mkuwa komwe kumagwiritsidwa ntchito poyambitsa kukonza zinthu.Ma PCB ambali imodzi komanso olimba omwe ali ndi mbali ziwiri safuna kusanjikiza kwamkati ndikupita molunjika pobowola.Ngati PCB ili ndi mitundu yambiri, kukonzekera kwazinthu zofananako kudzachitika, koma mwa mawonekedwe a zigawo zamkati, zomwe nthawi zambiri zimakhala zowonda kwambiri ndipo zimatha kumangidwa mpaka makulidwe omaliza okonzedweratu (stackup).
Kukula kwa gulu lodziwika bwino ndi 18 ″ x24 ″, koma kukula kulikonse kuyenera kugwiritsidwa ntchito bola kuli mkati mwa PCB yopanga.
4. Multilayer PCB yekha - mkati wosanjikiza processing
Pambuyo pa miyeso yoyenera, mtundu wazinthu, makulidwe apakati ndi kulemera kwa mkuwa wa wosanjikiza wamkati zakonzedwa, zimatumizidwa kubowola mabowo opangidwa ndi makina ndikusindikiza.Mbali zonse ziwiri za zigawozi zimakutidwa ndi photoresist.Gwirizanitsani mbalizo pogwiritsa ntchito zojambula zamkati ndi mabowo a zida, kenaka muwonetseni mbali iliyonse ku kuwala kwa UV kufotokoza za mawonekedwe ndi mawonekedwe omwe atchulidwa pamndandandawo.Kuwala kwa UV komwe kumagwera pa photoresist kumamangirira mankhwala kumtunda wa mkuwa, ndipo mankhwala otsala osawonekera amachotsedwa mubafa lomwe likukula.
Chotsatira ndikuchotsa mkuwa wowonekera kudzera munjira yolumikizira.Izi zimasiya zizindikiro zamkuwa zobisika pansi pa photoresist wosanjikiza.Panthawi ya etching, zonse zomwe zili mu etchant ndi nthawi yowonetsera ndizofunika kwambiri.Kukaniza kumavulidwa, ndikusiya mawonekedwe ndi mawonekedwe amkati.
Otsatsa ambiri a PCB amagwiritsa ntchito makina oyendera okha kuti ayang'ane zigawo ndi nkhonya zapambuyo kuti ziwongolere mabowo a zida zoyatsira.
5. Multilayer PCB yokha - Laminate
Mulu wokonzedweratu wa ndondomekoyi umakhazikitsidwa panthawi ya mapangidwe.Njira yopangira lamination imachitika m'chipinda choyera chokhala ndi chosanjikiza chathunthu chamkati, prepreg, zojambula zamkuwa, mbale zosindikizira, mapini, spacers zitsulo zosapanga dzimbiri ndi mbale zothandizira.Makina osindikizira aliwonse amatha kukhala ndi matabwa 4 mpaka 6 pakutsegula kwa atolankhani, kutengera makulidwe a PCB yomalizidwa.Chitsanzo cha 4-layer board stackup chingakhale: platen, separator zitsulo, zojambula zamkuwa (4th layer), prepreg, core 3-2 layers, prepreg, copper foil, ndi kubwereza.Pambuyo 4 mpaka 6 ma PCB asonkhanitsidwa, tetezani mbale yapamwamba ndikuyiyika mu makina osindikizira.Makina osindikizira amakwera mpaka pamakona ndikugwiritsa ntchito kukakamiza mpaka utomoni usungunuke, pomwe prepreg imayenda, kulumikiza zigawozo palimodzi, ndipo makinawo amazizira.Akatulutsidwa ndikukonzekera
6. Kubowola
Kubowola kumachitidwa ndi makina obowola a CNC oyendetsedwa ndi malo ambiri omwe amagwiritsa ntchito spindle yapamwamba ya RPM ndi kabowo ka carbide opangidwira pobowola PCB.Vis wamba amatha kukhala ang'onoang'ono ngati 0.006 ″ mpaka 0.008 ″ okhometsedwa pa liwiro la 100K RPM.
Kubowola kumapanga khoma loyera, losalala la dzenje lomwe silingawononge zigawo zamkati, koma kubowola kumapereka njira yolumikizira zigawo zamkati mutatha kuyika, ndipo dzenje losadutsa limatha kukhala kunyumba kupita ku zigawo za dzenje.
Mabowo osakutidwa nthawi zambiri amabowoledwa ngati ntchito yachiwiri.
7. Kupaka mkuwa
Electroplating imagwiritsidwa ntchito kwambiri pakupanga kwa PCB komwe kumafunikira mabowo.Cholinga chake ndi kuyika mkuwa pagawo lothandizira pogwiritsa ntchito mankhwala osiyanasiyana, kenako kudzera mu njira zotsatizana ndi electroplating kuti muchuluke makulidwe a mkuwawo mpaka makulidwe ake, nthawi zambiri 1 mil kapena kupitilira apo.
8. Akunja wosanjikiza mankhwala
Kukonzekera kwakunja kosanjikiza kwenikweni kumakhala kofanana ndi njira yomwe idafotokozedwera kale pagawo lamkati.Mbali zonse za pamwamba ndi pansi zimakutidwa ndi photoresist.Gwirizanitsani mbalizo pogwiritsa ntchito zojambula zakunja ndi mabowo a zida, kenaka yikani mbali iliyonse ku kuwala kwa UV kuti mufotokoze mwatsatanetsatane mawonekedwe olakwika a mawonekedwe ndi mawonekedwe.Kuwala kwa UV komwe kumagwera pa photoresist kumamangirira mankhwala kumtunda wa mkuwa, ndipo mankhwala otsala osawonekera amachotsedwa mu bafa lomwe likukula.Chotsatira ndikuchotsa mkuwa wowonekera kudzera munjira yolumikizira.Izi zimasiya zizindikiro zamkuwa zobisika pansi pa photoresist wosanjikiza.Kukaniza kumavulidwa, ndikusiya mawonekedwe ndi mawonekedwe akunja.Zowonongeka zakunja zimatha kupezeka pamaso pa solder chigoba pogwiritsa ntchito makina owonera.
9. Phala la solder
Kugwiritsa ntchito chigoba cha Solder ndikofanana ndi njira zamkati ndi zakunja.Kusiyana kwakukulu ndiko kugwiritsa ntchito chigoba chojambula zithunzi m'malo mwa photoresist pamtunda wonse wa gulu lopanga.Kenako gwiritsani ntchito zojambulajambula kuti mujambule zithunzi pamwamba ndi pansi.Pambuyo powonekera, chigobacho chimachotsedwa m'malo ojambulidwa.Cholinga chake ndikuwonetsa malo okhawo omwe zigawozo zidzayikidwe ndikugulitsidwa.Chigobacho chimachepetsanso kutha kwa PCB kumalo owonekera.
10. Chithandizo chapamwamba
Pali zosankha zingapo zomaliza pamwamba.Golide, siliva, OSP, solder wopanda lead, solder yokhala ndi lead, etc. Zonsezi ndizovomerezeka, koma wiritsani kwenikweni pazofunikira zopanga.Golide ndi siliva amagwiritsidwa ntchito ndi electroplating, pomwe ma solder opanda lead komanso okhala ndi lead amapangidwa mopingasa ndi solder yotentha.
11. Mayina
Ma PCB ambiri amatetezedwa pazolemba pamwamba pawo.Zolembazi zimagwiritsidwa ntchito makamaka pakusonkhanitsa ndipo zimaphatikizapo zitsanzo monga zolembera ndi zolembera za polarity.Zolemba zina zitha kukhala zophweka ngati chizindikiritso cha gawo kapena ma code amasiku opanga.
12. Gulu laling'ono
Ma PCB amapangidwa m'mapanelo athunthu omwe amafunikira kuchotsedwa pamapangidwe awo.Ma PCB ambiri amakhazikitsidwa m'magulu kuti apititse patsogolo luso la msonkhano.Pakhoza kukhala chiwerengero chopanda malire cha magulu awa.Sindingathe kufotokoza.
Zambiri zimayikidwa pa mphero ya CNC pogwiritsa ntchito zida za carbide kapena kugoletsa pogwiritsa ntchito zida zokutidwa ndi diamondi.Njira zonsezi ndi zovomerezeka, ndipo kusankha njira nthawi zambiri kumatsimikiziridwa ndi gulu la msonkhano, lomwe nthawi zambiri limavomereza gulu lomwe linamangidwa pakali pano.
13. Mayeso
Opanga PCB nthawi zambiri amagwiritsa ntchito kafukufuku wowuluka kapena bedi la kuyesa misomali.Njira yoyesera yotsimikiziridwa ndi kuchuluka kwazinthu ndi/kapena zida zomwe zilipo
