Ma board ozungulira a PCB amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana zamagetsi m'maiko otukuka masiku ano.Malinga ndi mafakitale osiyanasiyana, mtundu, mawonekedwe, kukula, wosanjikiza, ndi zinthu za matabwa ozungulira PCB ndizosiyana.Chifukwa chake, chidziwitso chomveka bwino chimafunikira pamapangidwe a matabwa ozungulira PCB, apo ayi, kusamvetsetsana kumatha kuchitika.Nkhaniyi mwachidule pamwamba zilema khumi zochokera mavuto mu ndondomeko kamangidwe ka matabwa PCB dera.
1. Tanthauzo la msinkhu wa processing silikudziwika bwino
Bolodi lambali imodzi limapangidwa pa TOP layer.Ngati palibe malangizo ochitira kutsogolo ndi kumbuyo, zingakhale zovuta kugulitsa bolodi ndi zipangizo.
2. Mtunda pakati pa malo akuluakulu zojambulazo zamkuwa ndi chimango chakunja uli pafupi kwambiri
Mtunda pakati pa zojambulazo zamkuwa zazikuluzikulu ndi chimango chakunja uyenera kukhala osachepera 0.2mm, chifukwa pogaya mawonekedwe, ngati agayidwa pazitsulo zamkuwa, n'zosavuta kuchititsa kuti zojambulazo zikhale zozungulira ndikupangitsa kuti solder ikane. kugwa.
3. Gwiritsani ntchito ma filler blocks kujambula mapepala
Mapadi ojambula okhala ndi midadada yodzaza amatha kudutsa kuyendera ku DRC popanga mabwalo, koma osati pokonza.Chifukwa chake, mapepala otere sangathe kupanga deta yachigoba cha solder.Pamene kukana kwa solder kumagwiritsidwa ntchito, malo a filler block adzaphimbidwa ndi solder resist, zomwe zimapangitsa kuti chipangizocho Kuwotcherera kumakhala kovuta.
4. Gawo lamagetsi lamagetsi ndi maluwa a maluwa ndi kugwirizana
Chifukwa chakuti amapangidwa ngati mphamvu yopangira mphamvu mu mawonekedwe a mapepala, nthaka yosanjikiza imatsutsana ndi chithunzi pa bolodi losindikizidwa, ndipo kugwirizana konse kuli mizere yodzipatula.Samalani pojambula magetsi angapo kapena mizere yambiri yodzipatula, ndipo musasiye mipata kuti mupange magulu awiriwa Kuzungulira kochepa kwa magetsi sikungapangitse kuti malo olumikizira atsekedwe.
5. Makhalidwe olakwika
Ma SMD pads a zilembo zophimba zilembo amabweretsa zovuta pakuyesa pa bolodi losindikizidwa ndi kuwotcherera mbali.Ngati mawonekedwe ake ndi ochepa kwambiri, apangitsa kuti kusindikiza kwa skrini kukhala kovuta, ndipo ngati kuli kwakukulu, zilembozo zimalumikizana, zomwe zimapangitsa kuti zikhale zovuta kusiyanitsa.
6.surface phiri chipangizo ziyangoyango ndi zazifupi kwambiri
Izi ndi zoyezetsa popanda ntchito.Pazida zowundana kwambiri zapamtunda, mtunda wapakati pa mapini awiriwo ndi wocheperako, ndipo mapadiwo amakhala owonda kwambiri.Mukayika zikhomo zoyesera, ziyenera kugwedezeka mmwamba ndi pansi.Ngati pad mapangidwe ndi lalifupi kwambiri, ngakhale si Izo zidzakhudza kuyika kwa chipangizo, koma zipangitsa zikhomo zoyesa kusalekanitsidwa.
7. Kuyika pabowo lapadindo la mbali imodzi
Mapadi a mbali imodzi nthawi zambiri sabowola.Ngati mabowo obowola akuyenera kulembedwa, pobowo ayenera kupangidwa ngati ziro.Ngati mtengo wapangidwa, ndiye kuti deta yobowola ikapangidwa, makonzedwe a dzenje adzawonekera pamalo awa, ndipo mavuto adzauka.Mapadi a mbali imodzi monga mabowo obowola ayenera kulembedwa mwapadera.
8. Padi palimodzi
Pobowola, chobowolacho chidzasweka chifukwa cha kubowola kangapo pamalo amodzi, zomwe zimapangitsa kuti dzenje liwonongeke.Mabowo awiri pa bolodi lamitundu yambiri amalumikizana, ndipo choyipacho chikakokedwa, chidzawoneka ngati mbale yodzipatula, zomwe zimapangitsa kuti zikhale zotsalira.
9. Pali midadada yodzaza kwambiri pamapangidwe kapena zodzaza zimadzazidwa ndi mizere yopyapyala kwambiri
Deta yojambula zithunzi imatayika, ndipo deta yojambula zithunzi sikwanira.Chifukwa chipika chodzaza chimakokedwa m'modzi ndi m'modzi pakujambula kwa data, ndiye kuchuluka kwa zojambula zowala kwambiri zomwe zimapangidwira, zomwe zimawonjezera zovuta pakukonza deta.
10. nkhanza wosanjikiza
Malumikizidwe ena opanda pake apangidwa pazithunzi zina.Poyamba anali bolodi la magawo anayi koma magawo opitilira asanu adapangidwa, zomwe zidayambitsa kusamvana.Kuphwanya mapangidwe ochiritsira.Zosanjikiza zazithunzi ziyenera kusungidwa bwino komanso zomveka bwino popanga.
