Ndi chitukuko chachangu cha magalimoto zamagetsi ndi mphamvu kulankhulana zigawo, kopitilira muyeso-wokhuthala mkuwa zojambulazo dera matabwa a 12oz ndi pamwamba pang'onopang'ono kukhala mtundu wapadera matabwa PCB ndi chiyembekezo yotakata msika, amene amakopa chidwi kwambiri opanga ndi chidwi;Ndi ntchito yaikulu ya matabwa ozungulira osindikizidwa m'munda wamagetsi, zofunikira zogwirira ntchito za zida zikuchulukirachulukira.Mapulani osindikizira osindikizira samangopereka malumikizano amagetsi ofunikira ndi chithandizo chamagetsi pazigawo zamagetsi, komanso pang'onopang'ono adzapatsidwa zambiri Ndi ntchito zowonjezera, matabwa osindikizira a mkuwa omwe amatha kuphatikizira magwero a magetsi, amapereka mphamvu zamakono komanso zodalirika kwambiri zakhala zodziwika pang'onopang'ono. zopangidwa ndi makampani PCB ndi ziyembekezo yotakata.

Pakadali pano, akatswiri ofufuza ndi chitukuko m'makampani apanga bwino a mbali ziwiri zosindikizidwa dera bolodi ndi makulidwe a mkuwa omalizidwa a 10oz kudzera munjira yosanjikiza yotsatizana yakuya motsatizana kwa mkuwa wa electroplated + thandizo losindikiza la ma solder angapo.Komabe, pali malipoti ochepa okhudza kupanga mkuwa wochuluka kwambiri matabwa ambiri osindikizidwa ndi makulidwe amkuwa omalizidwa a 12oz ndi kupitilira apo;nkhaniyi makamaka ikuyang'ana pa kafukufuku wotheka wa kupanga 12oz kopitilira muyeso-wokhuthala mkuwa multilayer matabwa osindikizidwa.Ukadaulo wokhuthala wamkuwa pang'onopang'ono wowongolera mwakuya + ukadaulo wopangira ma lamination, kuzindikira bwino kukonza ndi kupanga 12oz ultra-thick copper multilayer matabwa osindikizidwa.

Njira yopanga

2.1 Kupanga kotukuka

Ichi ndi 4 wosanjikiza, Kunja / mkati cooper makulidwe 12 oz, mphindi m'lifupi / danga 20/20mil, sungani monga pansipa:

2.1 Kuwunika kwa zovuta zogwirira ntchito

❶ Ukadaulo wopaka mkuwa wokhuthala kwambiri (zojambula zamkuwa ndi zokhuthala kwambiri, zovuta kuziyika): gulani zida zapadera za 12OZ, gwiritsani ntchito ukadaulo wakuya komanso woyipa wowongolera kuti muzindikire kukhazikika kwa mabwalo amkuwa okhuthala kwambiri.

❷ Ukadaulo wothirira wamkuwa wochuluka kwambiri: Ukadaulo waukadaulo wowongolera mbali imodzi-woyang'aniridwa mozama ndi vacuum ndi kudzaza kumagwiritsidwa ntchito kuti muchepetse zovuta za kukanikiza.Pa nthawi yomweyo, kumathandiza kukanikiza silikoni PAD + epoxy PAD kuthetsa vuto kopitilira muyeso-wokhuthala mkuwa laminate Mavuto luso monga mawanga woyera ndi lamination.

❸ Kuwongolera kolondola kwa mizere iwiri ya mzere wofanana wa mizere: kuyeza kwa kukulitsa ndi kutsika pambuyo pa kuyanika, kusintha kwa kukulitsidwa ndi kubweza malipiro a mzere;nthawi yomweyo, kupanga mzere kumagwiritsa ntchito LDI laser kujambula mwachindunji kuonetsetsa kuti pali kulondola kwazithunzi ziwirizi.

❹ Ukadaulo wobowola mkuwa wokhuthala kwambiri: Mwa kukhathamiritsa liwiro lozungulira, liwiro la chakudya, liwiro la kubwerera, moyo wa kubowola, ndi zina zambiri, kuwonetsetsa kuti kubowola bwino.

2.3 Mayendedwe a ndondomeko (tenga 4-wosanjikiza bolodi monga chitsanzo)

2.4 Njira

Chifukwa cha zojambula zamkuwa zokhuthala kwambiri, palibe 12oz wandiweyani wazitsulo zamkuwa pamsika.Ngati bolodi pachimake mwachindunji unakhuthala kwa 12oz, etching dera ndi kovuta kwambiri, ndipo etching khalidwe n'zovuta kutsimikizira;panthawi imodzimodziyo, kuvutika kwa kukanikiza dera pambuyo pa kuumba kwa nthawi imodzi kumawonjezekanso kwambiri., Kukumana ndi vuto lalikulu laukadaulo.

Pofuna kuthetsa mavuto omwe ali pamwambawa, pokonza mkuwa wochuluka kwambiri, zida zapadera za 12oz zamkuwa zimagulidwa mwachindunji pamapangidwe ake.Dera limatenga ukadaulo wowongolera pang'onopang'ono, ndiye kuti, zojambula zamkuwa zimakhazikika 1/2 makulidwe kumbali yakumbuyo → kukanikizidwa kuti mupange bolodi lamkuwa lakuda → etching kutsogolo kuti mupeze wosanjikiza wamkati. chitsanzo cha dera.Chifukwa cha kutsetsereka kwapang'onopang'ono, vuto la etching limachepetsedwa kwambiri, ndipo vuto la kukanikiza limachepetsanso.

❶ Mapangidwe a fayilo
Ma seti awiri a mafayilo amapangidwira gawo lililonse la dera.Fayilo yoyamba yolakwika iyenera kuwonetsedwa kuti iwonetsetse kuti dera liri pamalo omwewo panthawi ya kutsogolo / kumbuyo kuwongolera mozama, ndipo sipadzakhala kusokoneza.

❷ Sinthani kuwongolera mwakuya kwazithunzi zozungulira

❸ Kuwongolera kulondola kwazithunzi zachiwiri
Pofuna kuonetsetsa kuti mizere iwiriyi ikugwirizana, chiwerengero cha kukula ndi kutsika kuyenera kuyesedwa pambuyo pa lamination yoyamba, ndipo kukula kwa mzere ndi malipiro ochepetsera kuyenera kusinthidwa;nthawi yomweyo,

Kuyanjanitsa kwachidziwitso cha LDI laser imaging kumathandizira kulondola kwamayendedwe.Pambuyo kukhathamiritsa, kulondola kwa mayikidwe kumatha kuwongoleredwa mkati mwa 25um.

❹ Kuwongolera kwamtundu wapamwamba kwambiri kwa mkuwa
Pofuna kupititsa patsogolo kutsekemera kwa mabwalo amkuwa okhuthala kwambiri, njira ziwiri za etching ya alkaline ndi etching ya asidi zidagwiritsidwa ntchito poyesa kufananiza.Pambuyo potsimikizira, dera lokhala ndi asidi limakhala ndi ma burrs ang'onoang'ono komanso kulondola kwa mzere wapamwamba, womwe umatha kukwaniritsa zofunikira za mkuwa wokhuthala kwambiri.Zotsatira zake zikuwonetsedwa mu Table 1.

Ndi ubwino wa tsatane-tsatane ankalamulira etching kwambiri, ngakhale kuti vuto lamination yafupika kwambiri, ngati njira ochiritsira ntchito lamination, komabe akukumana ndi mavuto ambiri, ndipo n'zosavuta kubala zobisika khalidwe mavuto monga lamination. mawanga oyera ndi lamination delamination.Pachifukwachi, pambuyo poyerekezera mayeso ndondomeko ntchito silikoni PAD kukanikiza kungachepetse laminating mawanga oyera, koma bolodi pamwamba ndi wosagwirizana ndi kugawa chitsanzo, zomwe zimakhudza maonekedwe ndi khalidwe la filimu;ngati epoxy pad imathandizidwanso, kukanikiza kwabwino kumakhala bwino kwambiri, Kutha kukwaniritsa zofunikira za mkuwa wochuluka kwambiri.

❶ Njira yoyatsira mkuwa wokhuthala kwambiri

❷ Mtundu wapamwamba kwambiri wa copper laminate

Poyang'ana mkhalidwe wa magawo a laminated, dera limadzaza mokwanira, popanda ma micro-slit thovu, ndipo gawo lonse lozama kwambiri limakhala lokhazikika mu utomoni;nthawi yomweyo, chifukwa cha vuto la ultra-thick copper side etching, pamwamba mzere m'lifupi mwake ndi wokulirapo kuposa wopapatiza mzere m'lifupi pakati Pa pafupifupi 20um, mawonekedwe awa amafanana ndi "makwerero otembenuzidwa", omwe adzawonjezera kugwira kukanikiza, zomwe ndi zodabwitsa.

❷ Ukadaulo womanga mkuwa wochuluka kwambiri

Pogwiritsa ntchito njira zomwe tazitchulazi pang'onopang'ono zoyendetsedwa mozama zaukadaulo + wowongolera, zigawo zitha kuonjezedwa motsatizana kuti zizindikire kukonza ndi kupanga matabwa opangidwa ndi mkuwa wambiri wosanjikiza;nthawi yomweyo, pamene wosanjikiza wakunja wapangidwa, makulidwe amkuwa ndi pafupifupi pafupifupi.6oz, mumitundu yosiyanasiyana ya njira yopangira solder chigoba, imachepetsa kwambiri vuto la kupanga chigoba cha solder ndikufupikitsa kuzungulira kwa kupanga chigoba cha solder.

Kubowola mkuwa kochuluka kwambiri

Pambuyo kukanikiza kwathunthu, makulidwe a mbale yomalizidwa ndi 3.0mm, ndipo makulidwe onse amkuwa amafika 160um, zomwe zimapangitsa kuti zikhale zovuta kubowola.Panthawiyi, pofuna kuonetsetsa kuti kubowola bwino, magawo obowola adasinthidwa mwapadera m'deralo.Pambuyo kukhathamiritsa, kagawo kusanthula anasonyeza kuti kubowola alibe chilema monga misomali mitu ndi mabowo coarse, ndipo zotsatira zake ndi zabwino.

Chidule
Kudzera mu kafukufuku ndondomeko ndi chitukuko cha kopitilira muyeso-wokhuthala mkuwa multilayer kusindikizidwa bolodi, zabwino ndi zoipa ankalamulira kwambiri etching luso ntchito, ndi silikoni PAD + epoxy PAD ntchito kusintha khalidwe lamination pa lamination, amene bwino kuthetsa zovuta etching kopitilira muyeso-wokhuthala mkuwa dera Mavuto Common luso mu makampani, monga kopitilira muyeso-wokhuthala laminate mawanga woyera ndi angapo kusindikiza kwa solder chigoba, akwanitsa anazindikira processing ndi kupanga kopitilira muyeso-wokhuthala mkuwa multilayer kusindikizidwa matabwa;ntchito yake yatsimikiziridwa kukhala yodalirika, ndipo yakhutiritsa makasitomala 'Kufuna kwapadera kwamakono.

❶ Kuwongolera pang'onopang'ono ukadaulo wakuya wa mizere yabwino ndi yoyipa: kuthetsa bwino vuto la zokongoletsedwa ndi mizere yamkuwa yokhuthala kwambiri;
❷ Ukadaulo wowongolera mizere yolondola komanso yoyipa: kuwongolera bwino kulondola kwazithunzi ziwirizi;
❸ Ukadaulo wokulirapo kwambiri wamkuwa womanga mkuwa: umazindikira bwino kukonza ndi kupanga ma board osindikizidwa amitundu yambiri yamkuwa.

Mapeto
Mapulani osindikizidwa a mkuwa ochuluka kwambiri amagwiritsidwa ntchito kwambiri m'ma modules akuluakulu oyendetsa zipangizo zamagetsi chifukwa cha machitidwe awo amakono.Makamaka ndikukula kosalekeza kwa magwiridwe antchito ambiri, matabwa osindikizidwa kwambiri amkuwa akuyenera kuyang'anizana ndi chiyembekezo cha Msika.Nkhaniyi ndi yongotengera anzanu.
