Bolodi lowongolera bwino kwambiri limatanthawuza kugwiritsa ntchito mizere yabwino m'lifupi / katayanitsidwe, mabowo ang'onoang'ono, m'lifupi mwake (kapena opanda mphete m'lifupi) ndi maenje okwiriridwa ndi akhungu kuti mukwaniritse kachulukidwe kwambiri.

Kulondola kwambiri kumatanthauza kuti zotsatira za "zabwino, zazing'ono, zopapatiza, ndi zoonda" zidzatsogolera kulondola kwapamwamba. Tengani kukula kwa mzere monga chitsanzo:

0.20mm mzere m'lifupi, 0.16 ~ 0.24mm opangidwa mogwirizana ndi malamulo ndi oyenerera, ndipo cholakwika ndi (0.20±0.04) mm; pamene mzere wa mzere wa 0.10mm, cholakwikacho ndi (0.1 ± 0.02) mm, mwachiwonekere Kulondola kwachindunji kumawonjezeka ndi chinthu cha 1, ndi zina zotero sizovuta kumvetsa, kotero kuti zofunikira zolondola kwambiri sizidzakambidwa. mosiyana. Koma ndivuto lalikulu muukadaulo wopanga.

Ukadaulo wamawaya ang'onoang'ono komanso wandiweyani

M'tsogolomu, kukula kwa mzere wokwera kwambiri / phula kudzakhala kuchokera ku 0.20mm-0.13mm-0.08mm-0.005mm kuti akwaniritse zofunikira za SMT ndi multi-chip package (Mulitichip Package, MCP). Choncho, teknoloji yotsatirayi ikufunika.
①Substrate

Pogwiritsa ntchito zojambulazo zowonda kapena zowonda kwambiri zamkuwa (<18um) gawo lapansi ndiukadaulo wamankhwala apamwamba.
②Njira

Pogwiritsa ntchito filimu yowonda kwambiri komanso yonyowa, filimu yowonda komanso yabwino yowuma imatha kuchepetsa kupotoza kwa mzere ndi zolakwika. Kanema wonyowa amatha kudzaza mipata yaying'ono ya mpweya, kukulitsa mawonekedwe omatira, ndikuwongolera kukhulupirika kwa waya ndi kulondola.
③Kanema wa Electrodeposited Photoresist

Electro-deposited Photoresist (ED) imagwiritsidwa ntchito. Makulidwe ake amatha kuyendetsedwa mumitundu ya 5-30/um, ndipo imatha kupanga mawaya abwino kwambiri. Ndi oyenera makamaka yopapatiza mphete m'lifupi, palibe mphete m'lifupi ndi mbale zonse electroplating. Pakadali pano, pali mizere yopitilira khumi yopanga ED padziko lapansi.
④ Ukadaulo wowonetsa kuwala kofananira

Kugwiritsa ntchito ukadaulo wowonetsa kuwala kofananira. Popeza kuwala kofananirako kumatha kuthana ndi chikoka cha kusiyanasiyana kwa m'lifupi mwake chifukwa cha kuwala kwa oblique kwa gwero la "point", waya wabwino wokhala ndi kukula kwake kwa mzere ndi m'mbali zosalala atha kupezeka. Komabe, zida zowonetsera zofananira ndizokwera mtengo, ndalama ndizokwera, ndipo zimafunika kugwira ntchito pamalo aukhondo kwambiri.
⑤Ukadaulo wodziwikiratu wowunikira

Kugwiritsa ntchito ukadaulo wa automatic Optical inspection. Tekinoloje iyi yakhala njira yofunika kwambiri yodziwira popanga mawaya abwino, ndipo ikulimbikitsidwa, kugwiritsidwa ntchito ndikupangidwa mwachangu.

Ukadaulo wa Microporous

Mabowo ogwira ntchito a matabwa osindikizidwa omwe amagwiritsidwa ntchito pakukwera pamwamba pa teknoloji ya microporous amagwiritsidwa ntchito makamaka pogwirizanitsa magetsi, zomwe zimapangitsa kuti teknoloji ya microporous ikhale yofunika kwambiri. Kugwiritsa ntchito zipangizo ochiritsira kubowola ndi CNC pobowola makina kubala mabowo ting'onoting'ono ndi zolephera zambiri ndi mtengo wapamwamba.

Chifukwa chake, kuchuluka kwakukulu kwa matabwa osindikizidwa kumayang'ana kwambiri pakuwongolera mawaya ndi mapepala. Ngakhale zotsatira zazikulu zapezeka, kuthekera kwake kuli kochepa. Kuti mupititse patsogolo kachulukidwe (monga mawaya osakwana 0.08mm), mtengo wake ukukulirakulira. , Chifukwa chake tembenukirani kugwiritsa ntchito ma micropores kuti muwonjezere kachulukidwe.

M'zaka zaposachedwa, makina obowola manambala ndi ukadaulo wobowola yaying'ono apambana, motero ukadaulo wa micro-hole wakula mwachangu. Ichi ndiye gawo lalikulu kwambiri pakupanga kwaposachedwa kwa PCB.

M'tsogolomu, luso lopanga mabowo laling'ono lidzadalira kwambiri makina obowola a CNC ndi mitu yaying'ono, ndipo mabowo ang'onoang'ono opangidwa ndi ukadaulo wa laser akadali otsika kuposa omwe amapangidwa ndi makina obowola a CNC potengera mtengo ndi mtundu wa dzenje. .
① CNC pobowola makina

Pakali pano, luso CNC pobowola makina wapanga zopambana zatsopano ndi kupita patsogolo. Ndipo anapanga mbadwo watsopano wa CNC pobowola makina yodziwika ndi kubowola mabowo ting'onoting'ono.

Kugwiritsa ntchito bwino pobowola mabowo ang'onoang'ono (osakwana 0.50mm) a makina obowola ang'onoang'ono ndi 1 nthawi yayitali kuposa makina ochiritsira a CNC, osalephera pang'ono, ndipo liwiro lozungulira ndi 11-15r / min; imatha kubowola mabowo ang'onoang'ono a 0.1-0.2mm, pogwiritsa ntchito cobalt wambiri. Chobowola chaching'ono chapamwamba kwambiri chimatha kubowola mbale zitatu (1.6mm / chipika) zolumikizidwa pamwamba pa mzake. Chobowolacho chikathyoka, chimatha kuyimitsa ndikuwonetsa momwe chilili, chosinthira chobowolacho ndikuwunika m'mimba mwake (laibulale yazida imatha kusunga mazana a zidutswa), ndipo imatha kuwongolera mtunda wokhazikika pakati pa nsonga yobowola ndi chivundikiro. ndi kuya kwa kubowola, kotero mabowo akhungu akhoza kubowoledwa , Sizidzawononga countertop. Pamwamba pa tebulo la makina obowola a CNC amatengera mpweya ndi maginito levitation mtundu, omwe amatha kuyenda mwachangu, mopepuka komanso molondola kwambiri popanda kukanda tebulo.

Makina obowola oterowo akufunika pakadali pano, monga Mega 4600 ochokera ku Prurite ku Italy, mndandanda wa Excellon 2000 ku United States, ndi zinthu za m'badwo watsopano wochokera ku Switzerland ndi Germany.
②Kubowola kwa laser

Palidi mavuto ambiri ndi makina obowola a CNC ndi tizibowo tobowola mabowo ang'onoang'ono. Zalepheretsa kupita patsogolo kwaukadaulo wamabowo ang'onoang'ono, kotero kutulutsa kwa laser kwakopa chidwi, kafukufuku ndikugwiritsa ntchito.

Koma pali cholakwika chakupha, ndiko kuti, kupanga dzenje la nyanga, komwe kumakhala koopsa kwambiri pamene makulidwe a mbale akuwonjezeka. Kuphatikizidwa ndi kuwonongeka kwa kutentha kwapamwamba (makamaka matabwa ambiri), moyo ndi kukonza gwero la kuwala, kubwerezabwereza kwa mabowo owonongeka, ndi mtengo wake, kukwezedwa ndi kugwiritsa ntchito mabowo ang'onoang'ono popanga matabwa osindikizidwa kwaletsedwa. . Komabe, laser ablation imagwiritsidwabe ntchito mu mbale zoonda komanso zolimba kwambiri, makamaka muukadaulo wa MCM-L high-density interconnect (HDI), monga etching film polyester ndi kuyika zitsulo mu MCM. (Sputtering technology) imagwiritsidwa ntchito polumikizana kwambiri.

Mapangidwe a vias okwiriridwa m'mabwalo apamwamba kwambiri olumikizana ndi multilayer omwe amaikidwa m'manda komanso osawona kudzera m'mapangidwe angagwiritsidwenso ntchito. Komabe, chifukwa cha chitukuko ndi luso lamakono la makina obowola a CNC ndi ma micro-bowola, adalimbikitsidwa ndikugwiritsidwa ntchito mwamsanga. Chifukwa chake, kugwiritsa ntchito kubowola kwa laser pama board ozungulira okwera sikungapange malo apamwamba. Koma ikadali ndi malo mu gawo linalake.

③Ukadaulo wokwiriridwa, wakhungu, komanso pobowola

Kukwiriridwa, akhungu, komanso ukadaulo wophatikizira mabowo ndi njira yofunikira yowonjezerera kuchuluka kwa mabwalo osindikizidwa. Nthawi zambiri, mabowo okwiriridwa ndi osawona ndi timabowo tating'ono. Kuphatikiza pa kuchuluka kwa mawaya pa bolodi, mabowo okwiriridwa ndi akhungu amalumikizidwa ndi "pafupi" wosanjikiza wamkati, womwe umachepetsa kwambiri kuchuluka kwa maenje opangidwa, ndipo kudzipatula disk kudzakhalanso Kuchepetsa, potero kukulitsa chiwerengero cha mawaya ogwira mtima ndi kulumikiza kwapakati-wosanjikiza mu bolodi, ndikuwongolera kachulukidwe kakulumikizana.

Choncho, Mipikisano wosanjikiza bolodi ndi kuphatikiza kukwiriridwa, akhungu, ndi kudzera-mabowo ali osachepera 3 nthawi apamwamba interconnection kachulukidwe kuposa ochiritsira ochiritsira zonse-dzenje bolodi dongosolo pansi pa kukula ndi chiwerengero cha zigawo. Ngati m'manda, akhungu, Kukula kwa matabwa osindikizidwa pamodzi ndi mabowo adzakhala kwambiri yafupika kapena chiwerengero cha zigawo adzakhala kwambiri yafupika.

Choncho, m'magulu osindikizidwa opangidwa ndipamwamba kwambiri, matekinoloje okwiriridwa ndi osawona akhala akugwiritsidwa ntchito kwambiri, osati pamapepala osindikizidwa pamwamba pa makompyuta akuluakulu, zipangizo zoyankhulirana, ndi zina zotero, komanso ntchito za boma ndi mafakitale. Amagwiritsidwanso ntchito kwambiri m'munda, ngakhale m'ma board ena owonda, monga PCMCIA, Smart, IC makadi ndi ma board ena owonda asanu ndi limodzi.

Ma board ozungulira osindikizidwa okhala ndi mabowo okwiriridwa komanso osawona nthawi zambiri amamalizidwa ndi njira zopangira "sub-board", zomwe zikutanthauza kuti ziyenera kumalizidwa ndikukanikizira kangapo, kubowola, ndi kubowola mabowo, kotero kuyika bwino ndikofunikira kwambiri.
