Best Technology ndi mmodzi wa opanga bwino pcb ndi kusindikizidwa dera bolodi ogulitsa China
Mu gawo lalikulu la uinjiniya ndi kupanga, pali dziko lobisika la mabowo, lililonse liri ndi cholinga chake komanso malo ake. Mabowowa amagwira ntchito yofunika kwambiri pothandizira ntchito zosiyanasiyana zamakina ndi zamagetsi. Mu blog iyi, tiyamba ulendo wofufuza mitundu yosiyanasiyana ya mabowo mu bolodi losindikizidwa. Chifukwa chake, mangani malamba anu ndikulowa m'dziko losangalatsa la zinthu zaukadaulozi.
Mitundu Yodziwika Yamabowo mu PCB
Mukayang'ana bolodi loyang'anira dera, munthu amapeza mabowo angapo omwe amagwira ntchito zinazake. Izi zikuphatikizapo Via holes, PTH, NPTH, mabowo akhungu, mabowo okwiriridwa, mabowo a Counterbore, Countersunk mabowo, mabowo a Malo, ndi mabowo Fiducial. Mtundu uliwonse wa dzenje umakhala ndi gawo losiyana ndi ntchito zake mkati mwa PCB, zomwe zimapangitsa kuti zikhale kofunika kuti mudziwe bwino za mawonekedwe awo kuti muthandizire kupanga bwino kwa PCB.
1. Kudzera Mabowo
Kudzera mabowo ndi mipata ang'onoang'ono kulumikiza zigawo zosiyanasiyana za bolodi osindikizidwa dera (PCB). Amathandizira kuyenda kosasunthika kwa ma sigino ndi mphamvu pakati pa zigawo, zomwe zimapangitsa kuti pakhale mawonekedwe ozungulira komanso kufalitsa. Vias zitha kugawidwa m'mitundu iwiri: Yokutidwa Kupyolera-Mabowo (PTH) ndi Non-Plated Through-Holes (NPTH), iliyonse ikugwira ntchito zosiyanasiyana.
2. PTH (Yokutidwa ndi Bowo)
Plated Through-Holes (PTH) ndi vias ndi zinthu conductive ❖ kuyanika makoma amkati. Ma PTH amakhazikitsa kulumikizana kwamagetsi pakati pa magawo osiyanasiyana a PCB, kulola kudutsa kwa ma sign ndi mphamvu. Amagwira ntchito yofunika kwambiri pakulumikiza zigawo, kuwongolera kuyenda kwamagetsi, ndikuwonetsetsa kuti dera likuyenda bwino.
3. NPTH (Yosakutidwa ndi Bowo)
Non-Plated Through-Holes (NPTH) alibe zokutira zopangira pamakoma awo amkati, kuwapangitsa kukhala oyenera kumakina okha. Mabowowa amagwiritsidwa ntchito pothandizira makina, kuyanjanitsa, kapena ngati maupangiri oyika, osakhazikitsa zolumikizira zamagetsi. NPTHs imapereka bata ndi kulondola, kuonetsetsa kuti zigawozo zikhale zogwirizana ndi gulu la dera. Chosiyana kwambiri pakati pa PTH ndi NPTH ndichojambula chamkuwa chidzakutidwa pakhoma la dzenje pomwe NPTH sichifunikanso kupanga mbale.
4. Mabowo Akhungu
Mabowo akhungu ndi mabowo obowoledwa pang'ono omwe amalowera mbali imodzi yokha ya bolodi yozungulira. Amagwiritsidwa ntchito makamaka kuti alumikizane ndi gawo lakunja la bolodi ndi gawo lamkati, ndikupangitsa kuti gawo likhazikike mbali imodzi ndikubisala kwina. Mabowo akhungu amapereka kusinthasintha ndikuthandizira kukulitsa malo pamapangidwe ovuta a board board.
5. Mabowo Okwiriridwa
Mabowo okwiriridwa amatsekedwa kwathunthu mkati mwa bolodi lozungulira, kulumikiza zigawo zamkati popanda kupitilira ku zigawo zakunja. Mabowowa amabisika kumbali zonse za bolodi ndipo amathandiza kukhazikitsa kugwirizana ndi njira pakati pa zigawo zamkati. Mabowo okwiriridwa amalola mapangidwe a board board ocheperako, kuchepetsa zovuta zotsata njira ndikuwonjezera magwiridwe antchito a board. Amapereka njira yosasunthika komanso yophatikizika popanda kuwonekera kulikonse.
6. Mabowo a Counterbore
Mabowo a Counterbore ndi zotsalira za cylindrical zomwe zimapangidwira mitu ya mabawuti, mtedza, kapena zomangira. Amapereka phokoso lathyathyathya lomwe limalola zomangira kuti zikhale pansi kapena pansi pang'ono pamwamba pa zinthuzo. Ntchito yayikulu yamabowo a counterbore ndikupititsa patsogolo kukongola ndi magwiridwe antchito apangidwe popereka mawonekedwe osalala komanso owoneka bwino. Mabowowa amapezeka kawirikawiri muzopanga matabwa, zitsulo, ndi zomangamanga pomwe malo obisika kapena okulirapo amafunikira.
7. Mabowo a Countersunk
Mabowo a Countersunk ndi zipinda zamkati zomwe zimapangidwira kuti zikhale ndi mitu yopindika ya zomangira kapena zomangira. Amagwiritsidwa ntchito kuti awonetsetse kuti mitu ya screw ili pansi kapena pansi pang'ono. Mabowo a Countersunk amagwira ntchito zokongoletsa komanso zothandiza, kupereka mawonekedwe owoneka bwino komanso opanda cholakwika pomwe amachepetsa chiwopsezo cha ma snags kapena ma protrusions. Kusinthasintha kwawo kumawapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana, kuyambira kupanga mipando mpaka uinjiniya wamlengalenga.
8. Malo Mabowo
Malo Holes, omwe amadziwikanso kuti Reference Holes kapena Tooling Holes, amagwira ntchito ngati malo ofunikira pakuyanjanitsa ndi kuyika zigawo, magawo, kapena zosintha panthawi yopanga kapena kukonza. Mabowowa amaikidwa mwadongosolo kuti awonetsetse kuti akuyenda bwino komanso osasinthasintha, kuti azitha kusonkhanitsa bwino komanso kuchepetsa zolakwika.
9. Mabowo Fiducial
Ma Fiducial Holes, omwe amatchedwanso Fiducial Marks kapena Alignment Marks, ndi mabowo ang'onoang'ono olondola kapena zolemba zomwe zimayikidwa pamwamba kapena PCB (Bodi Yosindikizidwa). Mabowowa amakhala ngati malo owonetsera masomphenya, njira zopangira makina, kapena makamera owonera makina.
Pamene tikutsiriza ulendo wathu kudutsa dziko lochititsa chidwi la mabowo mu uinjiniya, tapeza chidziwitso chozama cha ntchito ndi malo a mabowo a counterbore, maenje otsukidwa, kudzera m'mabowo, PTH, NPTH, mabowo akhungu, ndi mabowo okwiriridwa. Mabowowa ndi zinthu zofunika m'mafakitale osiyanasiyana, zomwe zimathandizira kukongola, magwiridwe antchito, komanso luso la mapangidwe.
Pambuyo pofotokozera aliyense wa iwo, muyenera kumvetsa mozama za ntchito zawo, ndikuyembekeza izi ndizothandiza kwa inu mabowo apangidwe pa polojekiti yanu ya PCB !!
