Mawu oyamba

Ngakhale kukula kwachangu kwa PCB ukadaulo, opanga ma PCB ambiri amaganizira za kupanga bolodi la HDI, bolodi lolimba, ndege ndi zina zamagulu ovuta, komabe pali ma PCBS ena okhala ndi dera losavuta, kukula kocheperako komanso mawonekedwe ovuta mumsika womwe ulipo, ndi osachepera kukula kwa ma PCBS ena ndi ochepa ngati 3-4mm. Chifukwa chake, kukula kwa mbale yama kalasi ndikocheperako, ndipo mabowo oyika sangapangidwe pakapangidwe kazomaliza. N’zosavuta kutulutsa mbale m’mphepete otukukira kunja (monga akuwonetsera CHITSANZO. 1) pogwiritsa ntchito njira yokhazikitsira yakunja, phukusi la PCB pokonza, kulolerana kosaletseka, kupanga kotsika pang’ono ndi mavuto ena. Pepala ili, kupanga kwa PCB yaying’ono kwambiri kumawerengedwa ndikuyesedwa mozama, njira yopangira mawonekedwe imakonzedweratu, ndipo zotsatira zake ndizotsatira ziwiri ndi theka loyeserera pakupanga.

1. Kusanthula Mkhalidwe

Kusankha mawonekedwe mawonekedwe Machining ndi zokhudzana ndi ulamuliro mawonekedwe kulolerana, mawonekedwe mtengo Machining, mawonekedwe dzuwa Machining ndi zina zotero. Pakadali pano, njira zomwe anthu amagwiritsa ntchito popanga mawonekedwe ndikupera.

1.1 mphero mawonekedwe

Kunena zoona, mawonekedwe a mbale yosinthidwa ndi mawonekedwe a mphero ndiabwino, ndipo kulondola kwake kumakhala kwakukulu. Komabe, chifukwa cha kukula kwake kwa mbaleyo, kulondola kwake kwa mawonekedwe amphero kumakhala kovuta kuwongolera. Pogwiritsa ntchito mphero, chifukwa chachitsulo mkati mwa arc, gong Angle mkati mwa kukula kwa kukula ndi poyambira, kusankha kwa wodula kumakhala ndi malire ambiri, nthawi zambiri amatha kusankha 1.2 mm ndi 1.0 mm, 0.8 mm kapena wodula mphero kwa processing, chifukwa cha kudula chida ndi chochepa kwambiri, malire kudya liwiro, kuyambitsa dzuwa kupanga ndi otsika, ndi kupanga ndalama ndi ndi mkulu, kotero okha oyenera pang’ono, Maonekedwe osavuta, palibe zovuta zamkati zamkati za PCB.

1.2 a

Pakuchuluka kwa PCB yaying’ono, zotsatira zake zimakhala zochepa kwambiri kuposa momwe zimakhudzira mphero, pankhaniyi, njira yokhayo yotengera kufa. Nthawi yomweyo, pazitsulo zamkati za PCB, makasitomala ena amafunika kukonzedwa pamakona oyenera, ndipo ndizovuta kukwaniritsa zofunikira pobowola ndi kugaya, makamaka ma PCB omwe ali ndi zofunikira kwambiri pakulekerera ndi mawonekedwe osasintha, ndikofunikira kutengera mtundu wopondaponda. Kugwiritsa ntchito njira zopangira zokha kumakulitsa mtengo wopangira.

2 Kuyesa Koyeserera

Kutengera ndi zomwe takumana nazo pakupanga kwa PCB kotereku, tachita kafukufuku wakuya ndi zoyeserera kuchokera kuzinthu zopangira mawonekedwe a mphero, kufa kufa, V-kudula ndi zina zotero. Dongosolo loyesera lenileni likuwonetsedwa mu Gulu 1 pansipa:

3. Njira Yoyesera

3.1 chiwembu 1 – mkombero wa makina achitsulo achitsulo

Mtundu wa PCB yaying’ono kwambiri imakhala yopanda mawonekedwe amkati, zomwe zimafunikira mabowo owonjezera mu unit (CHITSANZO. 2). Pakutha kwa mbali zitatu za zingwe, mbali yomaliza ya zingwe, pali malo otseguka mozungulira bolodi, kotero kuti chosemera sichingagwedezeke, chinthu chomalizidwa chonse ndi chitsogozo cha chopangira mphero , kotero kuti chinthu chomalizidwa mu mawonekedwe a chodulira chimakhala chodziwikiratu. Chifukwa mbali zonse zakhala zikulowa m’malo oimitsidwa, palibe kuthandizira, motero kukulitsa mwayi waziphuphu ndi ma burr. Pofuna kupewa kusakhazikika kwamtunduwu, ndikofunikira kukhatitsa lamba wa gong pobowola mbale kawiri, kugaya gawo lililonse poyamba kuti zitsimikizire kuti pakadali zolumikizana pambuyo pokonza kulumikiza fayilo yonse ya mbiri (CHITSANZO. 3).

Zokambirana pamapangidwe amakapangidwe apamwamba kwambiri ndi PCB yaying’ono

Mphamvu ya kuyesa kwa gong pamakina otukuka: mitundu iwiri ili pamwambapa idakonzedwa, zidutswa 10 za mbale yomalizidwa zidasankhidwa mwachisawawa munthawi iliyonse, ndipo malo otsekemera adayesedwa pogwiritsa ntchito quadratic element. Kukula kotukuka kwa mbale yomalizidwa yomwe idakonzedwa ndi lamba woyambayo ndi yayikulu ndipo imafunika kukonzedwa moyenera. Mfundo yotereyi imatha kupewedwa pogwiritsa ntchito tinthu tomwe timapanga. 0.1mm, mukwaniritse zofunikira (onani Gulu 2), mawonekedwewa akuwonetsedwa pa Chithunzi 4, 5.

3.2 Dongosolo 2 —- Fine chosema makina mphero mawonekedwe

Popeza zida zosema sizingayimitsidwe pokonza, lamba wachitsulo mu Chithunzi 3 sangathe kugwiritsidwa ntchito. Malinga ndi kupanga kwa lamba wachitsulo mu Chithunzi 2, chifukwa chakukula kwakanthawi kochepetsera, kuti titha kuteteza mbale yomalizidwa kuti isanyamuke pokonza, ndikofunikira kuti muzimitse kupukuta pakukonza, ndikugwiritsa ntchito mbaleyo phulusa kuti akonze, kuti muchepetse kamangidwe kazomwe zimakhazikika.

Zotsatira zoyeserera zokongola zokongola pamalingaliro otukukira kunja: kukula kwa malo otukuka kumatha kuchepetsedwa ndikuwongolera malinga ndi njira yomwe tatchulayi. Kukula kwamalo otukuka kukuwonetsedwa mu Gome 3. Malo otsekemera sangathe kukwaniritsa zofunikira pamtunduwu, chifukwa chake zimafunikira kukonzanso mwatsatanetsatane. Maonekedwewa akuwonetsedwa pa Chithunzi 6:

3.3 Scheme 3 —- Chidziwitso chazithunzi za Laser

Sankhani zinthu zomwe zili ndi matenthedwe akunja a 1 * 3mm kuti ayesedwe, pangani mafayilo amtundu wa laser pamizere yakunja, malinga ndi magawo omwe ali mu Gulu 4, zimitsani zotsukira (kuti mbale isayamwe pokonza), ndikuchita kawiri -makalata a laser.

Zokambirana pamapangidwe amakapangidwe apamwamba kwambiri ndi PCB yaying’ono

Zotsatira: mawonekedwe a kukonza kwa laser pa bolodi popanda zopunthira, kukula kwakukwaniritsa kungakwaniritse zofunikira, koma laser pambuyo pa mawonekedwe a chinthu chomalizidwa cha kuipitsa kwa mpweya wakuda wakuda, komanso kuipitsa kotere chifukwa chakukula ndikochepa kwambiri, sikungathe gwiritsani ntchito kuyeretsa madzi am’magazi, kumwa mowa kutsuka sikungagwire bwino (onani chithunzi 7), zotulukapo zoterezi zitha kukwaniritsa zomwe makasitomala amafuna.

3.4 Scheme 4 —- Kutsimikiza kwa kufa

Kukonzekera kwa kufa kumatsimikizira kulondola kwa kukula ndi mawonekedwe amitundu yopondaponda, ndipo palibe malo otukuka (monga akuwonetsera M’CHITSANZO. 8). Komabe, pakupanga makina, ndikosavuta kutulutsa zovulaza zapakona zosavomerezeka (monga zikuwonetsedwa mu CHITSANZO. 9). Zolakwika ngati izi sizilandiridwa.

4. Kutsiliza

Pepala ili limayang’ana mavuto omwe ali pazitsulo zazitali kwambiri za PCB ndi mawonekedwe ololera a +/- 0.1mm. Malingana ngati mapangidwe oyenerera amapangidwa pakupanga ukadaulo waukadaulo komanso njira yoyenera yosankhira imasankhidwa malinga ndi zida za PCB ndi zosowa zamakasitomala, mavuto ambiri adzathetsedwa mosavuta.
