PCBA rau lub hom phiaj - tseem ceeb siv: kev cia siab engineering thiab huab ib puag ncig kev yoog
Hauv cov nplais uas tsis ua haujlwm yog intolerable - tsheb, thiab cov khoom siv kho mob, thiab cov khoom siv kho mob hloov chaw kom dhau los ua ib qho linchpin ntawm kev nyab xeeb thiab ua haujlwm. Lub Hom Phiaj -} Cov chaw tseem ceeb tau thov kom muaj cov pcbas uas tiv thaiv kev ua kom txhua yam, thiab ntev}}}} kev ua haujlwm ua haujlwm rau txoj kev tswj hwm nruj. Tsab ntawv no rho tawm hauv cov ntsiab lus tshwj xeeb engineering, cov ntawv tsim kho tshiab uas txhais tau cov kev sib tw siab ntawm PCBA, nrog rau cov kev sib tw ntawm huab kev hloov kho.
Cov ntsiab cai tseem ceeb ntawm lub hom phiaj - tseem ceeb pcba tsim
Lub Hom Phiaj - Tus Qauv Tsim Qauv PCBA Qhov Tseem Ceeb Tshaj Tawm "Kev Nyab Xeeb Kev Nyab Xeeb, txav mus dhau kev tsim cov kev tsim khoom.
Kev ntseeg tau - centric tsim cov hau kev tsim qauv
Derating Engineering: Cheebtsam tau ua haujlwm hauv qab lawv cov kev ntsuas tshaj tawm (hluav taws xob ntau tshaj plaws (voltage, tam sim no, kub) kom txuas ntxiv lub neej pabcuam. Piv txwv li, capacitors hauv tsheb BMS los ntawm 30% rau voltage thiab 50% rau qhov kub thiab txias, ua haujlwm {xyoo ntawm kev ua haujlwm.
Rov qab kos duab: Qhov kev ntsuas tseem ceeb (piv txwv li, Aerospace navigation modules) sib txuas cov khoom sib cav thiab cov kev sib tw, ua rau lub cev tsis sib xws tsis muaj qhov system kaw.
Thermal -} kev lag luam coatevatory}}: Finite elite tsom xam (FEA) simulates thermal tsim kev tsis sib xws (piv txwv li cov kua muag pad) thiab sib xyaw ua ke kom txo kev ntxhov siab los ntawm qhov kub ntxhov.
Cov ntaub ntawv tshwj xeeb rau cov xwm txheej huab
High -} kub subtrates: Tsis txhob txheem ntawm tus qauv fr- 4 (ntau dua {} {} {} Epoxy, nrog tooj liab thicknesses ntawm 70-105μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μ5μm rau kev ua kom muaj peev xwm thiab thermal conductivity.
Corrosion - Tsis taus nto tiav: 沉金 (Electroless npib nyiaj kub, rau ESPs) lossis Enc Composite hloov kho cov tshuaj pleev kua txiv hauv cov roj av lossis chaw muaj kev lag luam.
Potting thiab uaformal tsho tiv no: Silicone lossis polyurethane poticting tebchaw teb, muab cov tshuab poob siab) thiab rwb thaiv tsev tiv thaiv ya raws, plua plav.
