Gulu la madera ozungulira limatanthawuza kugwiritsa ntchito mzere wabwino / kutalika kwa mabowo, mabowo a mabowo, mphete yamtundu wapafupi (kapena palibe mabowo akhungu kuti akwaniritse kuchuluka kwambiri.
Kulondola kwambiri kumatanthauza kuti chifukwa cha "chabwino, chaching'ono, chopapatiza, ndipo zoonda" zimapangitsa kuti zikhale zofunikira kwambiri. Tengani chingwe m'lifupi mwake:
0,20mm mzere, 0.16 ~ 0.24mm yopangidwa molingana ndi malamulo ndi oyenerera, ndipo cholakwika ndi (0,20 ± 0,04) mm; Mzerewo ukukula ndi 0.10mm, cholakwika ndi (0.1 ± 0,02) mm, mwachiwonekere sizovuta kuzimvetsetsa za 1, motero sizovuta kwambiri kuzimvetsetsa, choncho zolondola kwambiri sizikuvuta kuzimva. Koma ndi vuto lotchuka pakupanga ukadaulo wopanga.
Ukadaulo wocheperako
M'tsogolomu, mzere wambiri wokwera / phula udzakhala wochokera ku 0,20mm-0.13mm-0.08mm kuti mukwaniritse zofunikira za SMT ndi Phukusi la TIP-TIPIP, MCITIPIP). Chifukwa chake, ukadaulo wotsatirawu ndi wofunikira.
①sswate
Kugwiritsa ntchito zojambula zowonda kapena zowonda kwambiri (<18um) gawo lalikulu la mankhwala.
②process
Kugwiritsa ntchito filimu yowonda komanso yonyowa yothina, filimu yowuma komanso yabwino yowuma imatha kuchepetsa kukula ndi zolakwika. Filimu yonyowa imatha kudzaza mipata yaying'ono ya mpweya, kunjezeka zotsatsa, ndikusintha umphumphu wa waya komanso kulondola.
③electrodeepreactist filimu
Electro-yoyikiridwa (Ed) imagwiritsidwa ntchito. Makulidwe ake amatha kuwongoleredwa mu mitundu ya 5-30 / UM, ndipo imatha kupanga mawaya abwino abwino. Ndioyenera kwambiri mphete yopapatiza, palibe mphete yofananira ndi magetsi athunthu. Pakadali pano, pali mizere yoposa khumi padziko lapansi.
④ kufanana ndi ukadaulo wowonekera
Kugwiritsa ntchito ukadaulo wofanana ndi ukadaulo. Popeza kuwonekera kwa kuwala kofanana kumatha kuthana ndi vuto la mzere wamtali wobwera chifukwa cha zotupa za "point" Komabe, zida zofananira zofananira ndizokwera mtengo, ndalamazo ndizokwera, ndipo zimafunikira kugwira ntchito yoyera.
⑤automatic maluso owoneka bwino
Kugwiritsa ntchito makina oyeserera owunikira. Tekinolojeyi yakhala njira yofunikira kwambiri pakupanga mawaya abwino, ndipo akudalitsidwa mwachangu, ndikugwiritsidwa ntchito.

Tekinoloji yopanda ukadaulo
Mabowo a mabodi omwe amagwiritsidwa ntchito popanga ukadaulo wa tizilombo mwamphamvu amagwiritsidwa ntchito makamaka pamagetsi amagetsi amagwiritsidwa ntchito makamaka pamagetsi amagetsi, zomwe zimapangitsa kuti kugwiritsa ntchito ukadaulo wa tizilombo kofunika kwambiri ndikofunika kwambiri. Pogwiritsa ntchito zida zokumba zobowola ndi makina obama a CNC kuti atulutse mabowo ang'onoang'ono ali ndi zolephera zambiri komanso ndalama zambiri.
Chifukwa chake, kuchuluka kwa mabodi osindikizidwa kumangoyang'ana kwambiri maaya ndi mapepala. Ngakhale zotsatira zabwino zakwaniritsidwa, kuthekera kwake kuli ndi malire. Kupititsa patsogolo kachulukidwe (monga mawaya ochepera 0.08mm), mtengo wake ukukulira. , Chifukwa chake tembenuzani kugwiritsa ntchito ma Microsent kuti musinthe kachikwama.
M'zaka zaposachedwa, makina oyendetsa ma Bizinesi amabowola ndi ukadaulo wa micro-bomba lamisala wapanga zopukutira, ndipo motero ukadaulo wa micro Ichi ndiye gawo lalikulu kwambiri pakupanga kwa PCB.
M'tsogolomu, ukadaulo wopanga mabowo amadalira makina apamwamba a CNC ndi mitu yayikulu kwambiri, ndipo mabomba ang'onoang'ono amapangidwa ndi makina a laser a laser omwe amapangidwa ndi makina ogulitsa a CNC kuchokera pamtengo ndi bowo.
Makina okwera ma ①cnc
Pakadali pano, ukadaulo wa makina obowola a CNC adapanga zopambana ndi kupita patsogolo. Ndipo adapanga m'badwo watsopano wa makina okwera ma CNC omwe amadziwika ndi kubowola timabowo.
Kuchita bwino kwa mabowo ang'onoang'ono (ochepera 0.50mm) mwa maboti a micro-hole okwera pamakina obangula a CNC, ndi zolephera zochepa, ndipo liwiro lozungulira ndi 11-15r / Min; Itha kubowola 0,1-0.2mm micro-mabowo, pogwiritsa ntchito mitengo yapamwamba kwambiri. Kubowoleza pang'ono pang'ono kumatha kubowola mbale zitatu (1.6mm / block) yolumikizidwa pamwamba pa wina ndi mnzake. Pamene kubowola pang'ono kwasweka, kumatha kuyimitsidwa ndikulongosola malowo, sinthani mabowo pang'ono ndikuwongoleredwa (mabowo akhungu amathanso kukhala ndi mabowo? Tebulo pamwamba pamakina a CNC amatengera mtundu wa mpweya ndi maginito, omwe amatha kusuntha mwachangu, ndikupepuka pang'ono osakanda patebulo.
Makina obowola oterewa ali pofunikira, monga Mega 4600 kuchokera ku Italy, mndandanda wa zigawo za ku United States, ndi zinthu zatsopano zochokera ku Switzerland ndi Germany.
②laser amabowola
Pali mavuto ambiri omwe ali ndi makina wamba a CNC Yalepheretsa kupita patsogolo kwaukadaulo wa micro-hole, kotero kuti laserlation ya laser yakopa chidwi, kafukufuku ndi ntchito.
Koma pali zolakwa zakufa, ndiye kuti, mapangidwe a bowo la lipenga, lomwe limakhala lalikulu kwambiri pamene makulidwe a mbale amawonjezeka. Kuphatikiza ndi kuwonongeka kwa kutentha kwambiri (makamaka mabomu a mitundu), moyo ndi kukonza mabowo, mabowo a mafumu ophuka, ndipo mtengo wake, ukukwezedwa ndi mabowo osindikizidwa. Komabe, kupukutira kwa laser kumagwiritsidwabe ntchito mbale zowonda komanso zazitali, makamaka mu ukadaulo wapamwamba (HDI) ukwati (HDI) .
Kupanga kwa kuyika kwa Viads kokulirapo kwambiri mabatani amisala okhala ndi malo oikidwa ndi nyumba zakhungu kungagwiritsidwenso ntchito. Komabe, chifukwa cha chitukuko ndi kusintha makonzedwe a CNC Chifukwa chake, kugwiritsa ntchito laser kumabowola m'matumbo a madera okwera sikungapangitse malo olamulira. Koma ilinso ndi malo m'munda wina.
Wosankhidwa, wakhungu, komanso kudzera mwaukadaulo
Kuikidwa m'manda, khungu, komanso mwapang'onopang'ono. Nthawi zambiri, oyikidwa m'manda ndi mabowo akhungu ndi mabowo ang'onoang'ono. Kuphatikiza pa kuchuluka kwa luntha pa bolodi, mabowo oyikidwa m'maso amalumikizidwa ndi "mawonekedwe a" omwe amachepetsa kuchuluka kwa mabowo, ndipo akuwonjezera kuchuluka kwa mabowo, ndikusintha kachulukidwe.
Chifukwa chake, bolodi lamitundu yambiri yosiyidwa, khungu, ndi kudzera m'mabowo nthawi zambiri zimakhala ndi kachulukidwe kakang'ono kambiri kuposa kuchuluka kwa bolodi. Ngati kuyikidwa m'maso, khungu, kukula kwa matabwa osindikizidwa ndi mabowo adzachepetsedwa kwambiri kapena kuchuluka kwa zigawo kudzachepa kwambiri.
Chifukwa chake, mokweza kwambiri mabodi osindikizidwa, adayikidwa m'manda ndi matekilolo omwe amapezeka pa makompyuta ambiri, zida zolankhulirana, ndi zina zambiri. Zagwiritsidwanso ntchito kwambiri m'munda, ngakhale m'matabwa ena opyapyala, monga pcmcia, makhadi a IC ndi mabodi ena owonda asanu ndi asanu ndi atatu.
Mabwalo osindikizidwa ndi mabwalo osindikizidwa nthawi zambiri amatsirizidwa ndi "sub-board", zomwe zikutanthauza kuti ayenera kumaliza kupsinjika, kubowola, ndi kuyika mabowo, moyenera kwambiri ndikofunikira.
