Cov chaw lag luam rau PCBA muaj qhov siab xav tau rau qhov chaw ntim khoom ntawm cov khoom siv hluav taws xob thiab cov khoom hauv Tshuag, tshwj xeeb yog rau av noo. Cov av noo ntau dhau yuav ua rau muaj kev phom sij rau cov khoom siv hluav taws xob thiab SMT nti ua cov khoom siv, cov khoom siv sib dhos thiab lwm yam. Nws tau tshaj tawm tias ntau tshaj li ntawm 1/4 ntawm cov khoom lag luam tsim muaj qhov tsis zoo thoob ntiaj teb muaj feem xyuam nrog kev phom sij ntawm ya raws. Vaum yog qhov teeb meem tseem ceeb cuam tshuam rau cov khoom zoo, yog li vim li cas qhov kev phom sij ntawm noo noo zoo heev? Luv luv piav qhia qhov mob ntawm noo noo rau ntau yam khoom siv thiab khoom siv.
1. Kev sib xyaw ua ke: Kev ya raws tuaj yeem nkag mus rau hauv IC los ntawm IC' s lub pob yas thiab los ntawm qhov khoob xws li pins, ua rau IC noo noo nqus. Tom qab ntawd, dej nqus pa dej yog tsim thaum lub sijhawm vuam cua kub cov txheej txheem ntawm SMT thaj ua, uas thaum kawg ua rau tawg thiab sab hauv oxidation ntawm IC resin pob ua rau cov khoom lag luam tsis ua tiav.
2. Cov khoom siv ua kua siv hluav taws xob: Txawm hais tias cov iav substrates, polarizers, thiab lim lub iav ntawm cov kua siv hluav taws xob xws li cov kua siv lead ua kua tau ntxuav thiab ziab hauv cov txheej txheem ntau lawm, lawv tseem yuav cuam tshuam los ntawm ya raws tom qab qhov kub qis, uas yuav ua rau txo qis hauv kev tsim nyog cov khoom lag luam.
3. Lwm cov khoom siv hluav taws xob: cov twj siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom sib txuas, cov hloov hluav taws xob, cov muag, PCBs, muaju, silicon wafers, quartz oscillators, SMT kua nplaum, cov khoom siv hluav taws xob nplaum, hluav taws xob hluav taws xob, cov khoom siv hluav taws xob siab thiab lwm yam khoom siv tau tag nrho cov ya raws.
4. Cov khoom siv hluav taws xob thaum lub sijhawm ua haujlwm: nruab nrab ntawm cov khoom lag luam ib nrab hauv pob thiab cov txheej txheem txuas ntxiv; nruab nrab ntawm PCBA pob thiab tom qab cov pob khoom mus rau lub hwj huam; IC, BGA, PCB, thiab lwm yam tom qab tsis rub tawm tab sis tseem tsis tau siv; tos soldering hauv qhov cub hluav taws xob pab kiag li lawm; cov cuab yeej ua kom sov tom qab ci; cov khoom tiav uas tsis tau ntim khoom, thiab lwm yam, yog raug ya raws.
5. Lub tshuab hluav taws xob ua tiav tiav kuj tseem yuav raug mob los ntawm ya raws thaum khaws cia hauv PCBA Hoobkas.
Cov av noo ntawm kev tsim khoom thiab ntim ib puag ncig ntawm PCBA Hoobkas yuav tsum qis dua 40%. Qee hom kuj xav tau qis av noo.
