Mabhodhi edunhu akadhindwa (PCBs) chikamu chakakosha chemidziyo yemagetsi yemazuva ano, inoshanda semusana wezvikamu uye zvinongedzo zvinobvumira zvigadzirwa zvemagetsi kushanda nemazvo. PCB kugadzira, inozivikanwawo sePCB yekugadzira, inzira yakaoma inosanganisira akawanda matanho kubva pakugadzira kwekutanga kusvika pagungano rekupedzisira. Mune ino blog positi, isu tinotora zvakadzama muPCB yekugadzira maitiro, tichiongorora nhanho imwe neimwe uye kukosha kwayo.
1. Dhizaini uye marongero
Nhanho yekutanga mukugadzira PCB kugadzira marongerwo ebhodhi. Mainjiniya anoshandisa komputa-inobatsira dhizaini (CAD) software kugadzira schematic dhayagiramu inoratidza kubatana uye nzvimbo dzezvikamu. Kurongeka kunosanganisira kukwidziridza mamisikirwo ezviteshi, mapadhi, uye vias kuti ive nechokwadi chekukanganisika kushoma uye kuyerera kwechiratidzo.
2. Kusarudzwa kwezvinhu
Kusarudzwa kwezvinhu zvePCB kwakakosha pakuita kwayo uye kusimba. Zvishandiso zvakajairika zvinosanganisira fiberglass yakasimbiswa epoxy laminate, inowanzonzi FR-4. Iyo mhangura yemhangura pabhodhi redunhu yakakosha pakuitisa magetsi. Ukobvu uye hutano hwemhangura hunoshandiswa hunoenderana nezvinodiwa zvedunhu.
3. Gadzirira substrate
Kana imwe nguva dhizaini yakagadziriswa uye zvinhu zvakasarudzwa, nzira yekugadzira inotanga nekucheka substrate kune zviyero zvinodiwa. Iyo substrate inobva yacheneswa uye yakaputirwa nemhangura yemhangura, ichiita hwaro hwenzira dzekufambisa.
4. Etching
Mushure mekugadzirira substrate, danho rinotevera nderokubvisa mhangura yakawandisa kubva pabhodhi. Kuita uku, kunonzi etching, kunoitwa nekushandisa chinhu chisingachinji asidhi chinonzi mask kudzivirira maronda emhangura anodiwa. Iyo nzvimbo isina kuvharwa inobva yaiswa kune etching solution, iyo inonyungudutsa mhangura isingadiwi, ichisiya chete nzira inodiwa yedunhu.
5. Kuchera
Kuchera kunosanganisira kugadzira maburi kana vias mune substrate kubvumira chikamu kuiswa uye magetsi kubatana pakati peakasiyana akaturikidzana edunhu bhodhi. Michina yekuchera inomhanya yakashongedzerwa nemabhiti ekubooresa chaiwo anogona kukina aya maburi madiki. Mushure mekunge maitiro ekuchera apera, maburi anoputirwa nezvinhu zvinoitisa kuti ave nechokwadi chekubatana kwakakodzera.
6. Plating uye solder mask application
Mabhodhi akacheneswa akaputirwa nehutete hwakatsetseka hwemhangura kusimbisa hukama uye kupa kuchengetedzwa kwakachengeteka kune zvikamu. Mushure mekuputira, solder mask inoiswa kuchengetedza mitsara yemhangura kubva kune oxidation uye kutsanangura iyo solder nzvimbo. Rudzi rwemasolder mask rinowanzo girini, asi rinogona kusiyana zvichienderana nezvinodiwa nemugadziri.
7. Kuiswa kwechikamu
Munhanho iyi, PCB yakagadzirwa inotakurwa nezvinhu zvemagetsi. Izvo zvikamu zvakanyatsoiswa pamapadhi ekuona kurongeka kwakaringana uye kutaridzika. Maitiro acho anowanzo otomatiki achishandisa pick-ne-nzvimbo michina kuti ive nechokwadi uye kunyatsoita.
8. Welding
Soldering inhanho yekupedzisira muPCB yekugadzira maitiro. Inosanganisira kupisa zvinhu uye mapads kugadzira yakasimba uye yakavimbika yemagetsi kubatana. Izvi zvinogona kuitwa uchishandisa wave solder muchina, uko bhodhi rinopfuudzwa nesaisai yeakanyungudutswa solder, kana nemanyorero solder matekiniki ezvikamu zvakaomarara.
Iyo PCB yekugadzira maitiro inzira ine hunyanzvi inosanganisira akati wandei matanho ekushandura dhizaini kuita dhizaini redunhu rinoshanda. Kubva pakugadzirwa kwekutanga uye dhizaini kusvika pakuiswa kwechikamu uye solder, nhanho imwe neimwe inobatsira pakushanda kwese uye kuvimbika kwePCB. Nekunzwisisa kuomesesa kwemaitiro ekugadzira, tinogona kuonga kufambira mberi kweruzivo rwemichina uko kwakaita kuti michina yemazuva ano yemagetsi ive diki, nekukurumidza, uye inoshanda zvakanyanya.
