Hauv kev ua haujlwm ntawm pcb, tus nqi ntawm kev txiav txim loj yog cuam tshuam los ntawm ntau yam, thiab muaj qhov sib txawv ntawm tus nqi ntawm cov khoom sib txawv. Cov kev sib txawv no tsis yog cov lej xwb, tab sis yog qhov tshwm sim los ntawm kev sib xyaw ua ke ntawm ntau yam xws li kev tsim khoom thiab kev pabcuam.
Qhov cuam tshuam ntawm kev xaiv raw khoom ntawm tus nqi
Cov ntaub ntawv raw yog lub hauv paus ntawm kev ua pcb, thiab lawv cov kev xaiv ncaj qha cuam tshuam rau cov nqi, uas cuam tshuam rau tus nqi. Cov neeg muag khoom sib txawv muaj cov kev sib txawv ntawm kev yuav khoom rau cov khoom siv raw thiab qib ntawm cov neeg muab khoom sib koom tes. Cov lag luam uas tsim kom ntev ntev - lub sij hawm ruaj khov kev sib raug zoo nrog high- cov khoom siv raw khoom zoo feem ntau tuaj yeem tau txais cov khoom zoo li - cov ntaub ntawv zoo xws li tooj liab - clad laminates thiab tooj liab foils ntawm tus nqi tsim nyog. Nyob rau tib lub sijhawm, hauv kev xaiv cov khoom siv tshwj xeeb, cov qauv tsim nyog thiab cov khoom siv tau raug xaiv kom raug raws li qhov xav tau tiag tiag ntawm ntau qhov kev txiav txim, tsis txhob raug nqi pov tseg los ntawm kev nrhiav siab heev ntawm - cov ntaub ntawv ua tau zoo thiab ua rau cov nqi sib tw. Yog li ntawd, thaum sib piv cov nqi, kev saib xyuas yuav tsum tau them rau qhov zoo thiab kev hloov pauv ntawm cov khoom siv raw siv los ntawm cov neeg muag khoom, tsis yog saib ntawm tus nqi ntawm tus nqi.
Qhov cuam tshuam ntawm cov txheej txheem ntau lawm thiab kev lag luam ntawm nplai
Cov qib siab tshaj plaws ntawm kev tsim cov thev naus laus zis thiab qhov loj ntawm cov nplais ntau lawm muaj feem cuam tshuam rau tus nqi loj - nplai pcb ua. Cov neeg muag khoom nrog cov txheej txheem ntau lawm tuaj yeem txhim kho kev tsim khoom, txo kev siv hluav taws xob thiab cov khoom siv poob rau ib chav tsev ntawm cov khoom, thiab yog li tau txais tus nqi kom zoo dua. Piv txwv li, kev siv cov kab ntau lawm tuaj yeem txo cov nqi ua haujlwm, txhim kho cov khoom sib xws, txo tus nqi rov ua haujlwm, thiab txo qis tus nqi.
Tsis tas li ntawd, cov neeg muag khoom nrog cov nplai ntau lawm tuaj yeem ua tau zoo dua kev lag luam ntawm cov nplai thaum ua cov khoom loj ntawm kev txiav txim. Kev siv cov cuab yeej siv tau siab, thiab cov nqi tas li faib rau txhua yam khoom (xws li cov khoom siv depreciation, Hoobkas leasing, thiab lwm yam) kuj qis, yog li muaj ntau chav rau kev hloov kho nqi. Cov chaw muag khoom me me, ntawm qhov tod tes, tej zaum yuav muaj cov nqi tsev siab dua thiab tsis muaj nqi zoo thaum ua cov xaj loj vim muaj cov khoom siv tsawg.
Qhov sib txawv ntawm kev pabcuam thiab tus nqi ntxiv
Tus nqi sib piv ntawm loj - nplai pcb ua tsis tuaj yeem tsis quav ntsej qhov sib txawv ntawm kev pabcuam thiab tus nqi ntxiv. Qee tus neeg muag khoom tuaj yeem muab cov kev pabcuam zoo tshaj -cov kev pabcuam zoo thoob plaws hauv tag nrho cov txheej txheem los ntawm kev lees paub qhov kev txiav txim mus rau tom qab- kev muag khoom, xws li cov lus teb ceev rau cov kev xav tau ntawm kev txiav txim, tiag- sijhawm taug qab ntawm kev tsim khoom, thiab kev pab daws teeb meem uas yuav tshwm sim thaum siv tom qab. Txawm hais tias cov kev pabcuam no tsis raug cuam tshuam ncaj qha rau hauv tus nqi ua haujlwm, lawv tuaj yeem txuag cov neeg siv khoom lub sijhawm thiab lub zog, txo cov nqi kev sib txuas lus thiab kev pheej hmoo, thiab tag nrho txhim kho tus nqi- kev koom tes zoo.
Tsis tas li ntawd, qee tus neeg muag khoom kuj tseem tuaj yeem muab cov kev pabcuam ntxiv, xws li kev pabcuam hauv kev ua kom zoo dua qub thiab muab cov ntaub ntawv xeem, uas tuaj yeem cuam tshuam rau cov neeg siv khoom txiav txim siab ntawm tus nqi. Thaum sib piv cov nqi, nws yog ib qho tsim nyog yuav tsum tau soj ntsuam xyuas seb cov kev pabcuam no thiab cov nqi ntxiv puas tuaj yeem ua tau raws li tus kheej xav tau, thiab tom qab ntawd txiav txim qhov tsim nyog ntawm tus nqi.
Lub manifestation ntawm kev tswj cov saw khoom muaj peev xwm
Cov neeg muag khoom uas muaj peev xwm tswj tau cov saw hlau muaj zog tuaj yeem tswj tau cov nqi zoo dua hauv kev ua haujlwm loj - pcb, ua rau cov nqi ua tau zoo dua. Kev tswj cov saw hlau tau zoo tuaj yeem ua kom cov khoom siv raw khoom raws sij hawm, txo cov khoom lag luam stagnation los ntawm cov khoom siv tsis txaus, thiab txo cov nqi khoom muag thiab kev poob los ntawm kev tsim khoom qeeb. Nyob rau tib lub sijhawm, kev soj ntsuam zoo thiab kev tswj xyuas cov neeg siv khoom tuaj yeem ua kom muaj kev ruaj ntseg ntawm cov khoom siv raw zoo, txo cov khoom siv rov ua dua tshiab thiab pov tseg los ntawm cov khoom siv teeb meem, tsis ncaj qha tswj cov nqi ua haujlwm, thiab ua rau cov nqi sib tw.
