PCB Circuit Coffic Boards yog dav siv nyob rau hauv ntau yam khoom siv hluav taws xob hauv hnub no kev lag luam hauv ntiaj teb niaj hnub no. Raws li kev lag luam sib txawv, cov xim, cov duab, qhov loj me, txheej, thiab cov khoom ntawm PCB Circuit Cots yog qhov sib txawv. Yog li, cov ntsiab lus tseem ceeb yuav tsum tau nyob rau hauv kev tsim ntawm PCB Circuit Coffs, lwm yam kev to taub muaj feem yuav tshwm sim. Cov lus no ua ntu lus sab saum toj tsis xws raws cov teeb meem hauv cov txheej txheem tsim qauv ntawm PCB Circuit Court boards.
1. Cov lus txhais ntawm kev ua tiav qib tsis meej
Cov rooj tsavxwm sab-pawg yog tsim nyob rau ntawm txheej sab saum toj. Yog tias tsis muaj kev qhia ua nws pem hauv ntej thiab nraub qaum, nws yuav nyuaj rau cov pab pawg thawj coj nrog nws.
2. Qhov kev ncua deb ntawm thaj chaw loj tooj liab ntawv ci thiab cov ncej sab nraud yog ib yam nkaus
Qhov kev ncua deb ntawm thaj chaw loj tooj liab ntawv ci thiab cov ncej sab nraud yuav tsum muaj tsawg kawg 0.2 hli, vim tias thaum lub tshuab tooj liab, vim tias thaum lub tshuab raj loj los tiv thaiv kom poob.
3. Siv cov chaw ua haujlwm kom kos cov ntaub qhwv
Daim duab ncoo nrog cov thawv ntim cov thawv tuaj yeem hla cov drc tshuaj xyuas thaum tsim kev hloov tsheb, tab sis tsis yog ua. Yog li, xws li cov ntaub qhwv tsis ncaj qha tsim cov ntaub ntawv npog ntsej muag. Thaum kev tiv thaiv tawm tsam yog thov, thaj tsam ntawm cov chaw muab cov chaw muab rau los ntawm kev sib tsoo tiv thaiv, ua rau lub cuab yeej vuam yog qhov nyuaj.
4. Lub hauv av hauv av txheej yog lub paj ncoo thiab kev sib txuas
Vim tias nws tau tsim los ua lub zog hluav taws xob hauv daim ntawv ntawm cov ntaub qhwv, cov av hauv av yog qhov sib txawv ntawm cov duab ntawm cov ntawv luam tawm tiag tiag, thiab txhua txoj kab sib txuas tau raug cais cov kab. Ceev faj ob txoj kev teeb tsa cov khoom siv hluav taws xob lossis ntau txoj kab kev cais tawm, thiab tsis txhob tso cov kab sib cais ua kom ob pab neeg tsis tuaj yeem ua rau thaj chaw sib txuas.
5. Cov cim tsis raug
SMD Pads ntawm lub cim npog cov ntaub qhwv rau kev sim ntsuas ntawm cov ntawv luam tawm thiab sib ntaus sib tua. Yog hais tias tus qauv tsim tau me me heev, nws yuav ua kom vijtsam dhau los, thiab yog tias nws loj dhau lawm, cov cim yuav sib tshooj sib txawv, ua rau nws nyuaj rau kev paub qhov txawv.
6.Surface Mount Khoom Siv Cov Ncauj Lus yog luv heev
Qhov no yog rau kev xeem tawm. Rau cov khoom siv ntom ntom ntom ntom ntom ntom ntom nti, qhov kev ncua deb ntawm ob lub pins yog qhov me me heev, thiab cov ntaub qhwv tseem yuag heev. Thaum txhim kho cov pins ntsuas, lawv yuav tsum yog qhov tsis txaus siab thiab qis dua. Yog tias lub ncoo tsim tau luv heev, txawm hais tias nws tsis yog nws yuav cuam tshuam rau lub installation ntawm lub cuab yeej, tab sis nws yuav ua rau kev sim pins tsis muaj kev sib luag.
7. Tib sab-sab ntim aperture chaw
Ib leeg seem seem yog feem ntau tsis yog drilling. Yog hais tias lub qhov ntxa yuav tsum tau cim, lub aperture yuav tsum tsim raws li xoom. Yog tias tus nqi tsim, tom qab ntawd thaum cov ntaub ntawv drilling yog tsim tawm, lub qhov sib txuas tes yuav tshwm sim ntawm txoj haujlwm no, thiab teeb meem yuav tshwm sim. Ib sab-sided pads xws li drilled lub qhov yuav tsum tau cim tshwj xeeb.
8. Ncaim Overlap
Thaum lub sijhawm drilling, lub laum me ntsis yuav tawg vim ntau qhov chaw nyob hauv ib qho chaw, ua rau lub qhov kev puas tsuaj. Qhov ob lub qhov nyob hauv ntau txheej board sib tshooj, thiab tom qab qhov tsis zoo yog kos, nws yuav tshwm sim raws li daim phaj cais, ua rau seem.
9. Muaj ntau ntau txoj kev sib sau hauv cov qauv tsim lossis cov puv txhaws tau muaj cov kab nyias nyias
Cov ntaub ntawv yees duab yog ploj, thiab cov duab yees duab tsis tiav. Vim tias txhaws ib qho los ntawm ib qho los ntawm ib qho ntawm lub teeb nqus cov ntaub ntawv ua, yog li cov ntaub ntawv teeb duab tsim yog heev loj, uas nce cov kev nyuaj ntawm cov ntaub ntawv kev ua haujlwm.
10. Daim duab txheej txheem kev tsim txom
Qee qhov kev sib txuas tsis zoo tau ua rau qee cov duab duab. Nws yog thawj zaug plaub-txheej pawg thawj coj tab sis ntau dua tsib txheej ntawm cov voj voog tau tsim, uas ua rau tsis muaj kev nkag siab. Kev ua txhaum ntawm kev tsim qauv. Cov duab txheej txheej yuav tsum khaws cia kom zoo thiab meej thaum tsim.
