Zvisinei nekukurumidza kukura kwe PCB tekinoroji, vazhinji vePBB vagadziri vanotarisisa kugadzirwa kweiyo HDI bhodhi, yakaoma bhajeti bhodhi, backplane uye zvimwe zvakaoma bhodhi zvikamu, asi kuchine mamwe maPCBS ane dunhu rakareruka, diki diki yeyuniti saizi uye chimiro chakaomarara mumusika uripo, uye hushoma saizi yemamwe maPCBS akatomboita kunge diki se3mmmm. Naizvozvo, chiyero cheyuniti yemaplate ekirasi idiki kwazvo, uye maburi ekumisikidza haakwanise kugadzirwa panguva yekumberi-kumagumo dhizaini. Zviri nyore kuburitsa ndiro yekumucheto convex mapoinzi (sezvakaratidzwa muFIG. 1) nekushandisa nzira yekunze yekumisikidza, vacu pcb panguva yekugadzirisa, isingadzoreke chimiro shiviriro, kushomeka kwekugadzira kugona uye mamwe matambudziko. Mune bepa iri, kugadzirwa kweiyo diki-diki saizi pcb inodzidziswa uye kuyedzwa zvakadzama, iyo nzira yekugadzirisa nzira yakagadziridzwa, uye mhedzisiro yacho yakapetwa kaviri mhedzisiro nehafu yekuyedza mukugadzirwa chaiko.

1. Mamiriro Ekuongorora

Sarudzo yechimiro machining modhi inoenderana nechimiro kushivirira kudzora, chimiro machining mutengo, chimiro machining kugona uye zvichingodaro. Parizvino, zvakajairika chimiro kugadzirisa nzira vari azvikuya chimiro uye vofa.

1.1 azvikuya chimiro

Kazhinji kutaura, chitarisiko mhando cheplate chakagadziriswa nekugaya chimiro chakanaka, uye iko kweyechokwadi kukwirira kwakakwirira. Nekudaro, nekuda kweiyo diki saizi yeplate, iyo yechipiri kurongeka kweyekugaya chimiro kunonetsa kudzora. Kana uchikuya chimiro, nekuda kwegong mukati me arc, gong Angle mukati memuganhu wehukuru uye groove upamhi, sarudzo yeakacheka saizi ine zvipingamupinyi zvakakura, yakawanda yenguva inogona kungosarudza 1.2 mm uye 1.0 mm, 0.8 mm kana kunyange yekucheka cheka yekugadzirisa, nekuda kwekucheka chishandiso idiki kwazvo, iyo yekumhanyisa kumhanyisa miganho, inotungamira mukugadzirwa kwekugadzira yakaderera, uye iyo yekugadzira mutengo iri yakanyanya kukwirira, saka inokodzera chete shoma shoma, Chitarisiko chakareruka, hapana chakaomarara chemukati gongs PCB chitarisiko chekugadzirisa.

1.2 iyo

Mukuita kwehuwandu hwakawanda hweiyo diki saizi pcb, kukanganisa kwekushomeka kwekugadzira kwakakwirira zvakanyanya kupfuura iko kukanganisa kwemakorari ekugaya mutengo, mune ino kesi, ndiyo chete nzira yekutora iyo kufa. Panguva imwecheteyo, yezvigunwe zvemukati zviri muPCB, vamwe vatengi vanoda kuti zvigadziriswe mumakona akakodzera, uye zvinonetsa kuzadzikisa zvinodikanwa nekuchera nekugaya, kunyanya kune avo vePCB vane zvakakwirira zvinodiwa zvechimiro shiviriro uye chimiro kusagadzikana, iyo zvinonyanya kudikanwa kutora iyo yekutsika nzira. Uchishandisa iyo yekufa yekuumba maitiro chete ichawedzera iyo yekugadzira mutengo.

2 Ongororo Dhizaini

Kubva pane yedu yekugadzira ruzivo rwemhando iyi yePCB, isu takaita zvakadzama kutsvagisa uye kuyedza kubva kumativi ekugaya chimiro kugadzirisa, kutsika kufa, V-kutemwa zvichingodaro. Iyo chaiyo chirongwa chekuyedza inoratidzwa muTafura 1 pazasi:

3. Maitiro Ekuyedza

3.1 Scheme 1 —- gwara re gong muchina hwokugaya

Rudzi urwu rudiki-saizi pcb inowanzo isina mamiriro emukati, ayo anoda mamwe maburi ekumisikidza muchikamu (FIG. 2). Kana panoperera mativi matatu ematinji, iro rekupedzisira gongs, pane nzvimbo dzakashama dzakakomberedza bhodhi, kuitira kuti mucheki asagone kusimbiswa, chigadzirwa chakapedzwa sechirevo nekutungamira kweyekuchera cutter offset , Saka kuti chigadzirwa chakapedzwa muchimiro checheki poindi yakajeka convex poindi. Nekuti mativi ese anga achikuya mune yakamiswa nyika, hapana rutsigiro, nekudaro ichiwedzera mukana wemaputi nemabhureki. Kuti udzivise hunhu uhu husina kumira zvakanaka, zvinodikanwa kukwidziridza bhandi regong nekugaya ndiro kaviri, kugaya chikamu cheyuniti yega kutanga kuona kuti kuchine mabhatani ekubatanidza mushure mekugadzirisa kubatanidza yakazara faira faira (CHIVA. 3).

Kufuridzirwa kwe gong machining kuyedza pane convex poindi: mhando mbiri dziri pamusoro dze gong bhandi dzakagadziriswa, zvidimbu gumi zveplate yakapera zvakasarudzwa zvakasarudzika pasi pechimwe nechimwe mamiriro, uye povex point yakayerwa uchishandisa quadratic element. Ikoji yakakosha saizi yeiyo yakapera ndiro yakagadziriswa neyekutanga gong bhandi rakakura uye rinoda kugadziriswa kwebhuku. Iyo convex poindi inogona kunyatso kudzivirirwa nekushandisa yakagadziriswa machining gongs. 0.1mm, sangana nezvinodiwa zvemhando yepamusoro (ona Tafura 2), chimiro chinoratidzwa muMufananidzo 4, 5.

3.2 Plan 2 – Fine achiita zvokutemera muchina wekugaya chimiro

Sezvo michina yekuveza isingagone kumiswa panguva yekugadzirisa, bhanhire regong muChifananidzo 3 harigone kuiswa. Sekureva kwekugadzirwa kwebhandi gong muMufananidzo 2, nekuda kweiyo diki yekugadzirisa saizi, kuitira kuti dziva rakapedzwa ribviswe panguva yekugadzirisa, zvinofanirwa kudzima kutsvaira panguva yekugadzirisa, uye shandisa ndiro. dota kuti uigadzirise, kuitira kuti udzikise kugadzirwa kwemapoinzi enongedzo.

Mhedzisiro yeakanaka kuveza kugadzirisa kuyedza pane convex poindi: iyo convex poindi saizi inogona kudzikiswa nekugadziriswa zvinoenderana nenzira iri pamusoro yekugadzirisa. Ikoji yekukwirisa inoratidzwa muTafura 3. Iyo povex poindi haigone kusangana nehunhu hunodiwa, saka inoda kugadziriswa kwebhuku. Kuonekwa kunoratidzwa muMufananidzo 6:

3.3 Scheme 3 —- Laser chimiro chekuongorora

Sarudza zvigadzirwa zvine online zvekunze zviyero zve1 * 3mm yekuyedza, gadzira mafaera emafaira e laser pamwe nemitsara yekunze, zvinoenderana nematanho ari muTafura 4, dzima kutsvaira (kudzivirira ndiro kuti isayamwa panguva yekugadzirisa), uye kuitisa zvakapetwa -sides laser chimiro.

Kukurukurirana pane chimiro dhizaini yemhando yepamusoro uye diki saizi pcb

Mhedzisiro: chimiro che laser kugadziriswa pabhodhi pasina mapundu zvigadzirwa, saizi yekugadzirisa inogona kusangana nezvinodiwa, asi laser mushure mechimiro chechinhu chakapedzwa che laser kabhoni dema pamusoro pekusvibisa, uye rudzi urwu rwekusvibisa nekuda kwehukuru hwacho hudiki, haugone shandisa plasma kuchenesa, shandisa doro kuchenesa haigone kubata (ona mufananidzo 7), mhedzisiro yekugadzirisa iyi inogona kusangana nezvinodiwa nevatengi.

3.4 Scheme 4 —- Mhedzisiro yekusimbisa kufa

Kugadziriswa kwekufa kunovimbisa iko kwehukuru uye chimiro chezvikamu zvekutsika, uye hapana povex point (sezvakaratidzwa muFIG. 8). Nekudaro, mukuita kwemuchina, zviri nyore kuburitsa isina kujairika yekumanikidza kukona (sezvakaratidzwa muFIG. 9). Kukanganisa kwakasarudzika kwakadaro hakugamuchirwe.

4. Mhedziso

Iri bepa rinotarisa kumatambudziko ari akakwirira-chaiwo uye madiki-saizi pcb gongs ane chimiro chaicho kushivirira kwe +/- 0.1mm. Chero bedzi zvine musoro dhizaini inoitwa mukuita kweinjiniya dhata uye chaiyo yekugadzirisa modhi inosarudzwa zvinoenderana nezvinhu zvePCB uye zvinodiwa nevatengi, matambudziko mazhinji achagadziriswa zviri nyore.
