Kev tiv thaiv kev nyab xeeb ntawm kev khiav haujlwm BGA rov ua haujlwm

1.Tsis txhob siv kiv cua lossis lwm yam khoom siv ncaj qha rau lub chaw nres tsheb kho plaub hau thaum nws ua haujlwm, txwv tsis pub nws yuav ua rau muaj kev cuam tshuam tsis zoo cua sov phaj saum npoo, hlawv cov haujlwm tawm.

2.Thaum lub tshuab ua haujlwm, chaw ua haujlwm siab-cua kub tsis tuaj yeem tsis muaj kev sib txuas lus ncaj qha rau ntawm qhov khoom, nws yuav ua rau muaj hluav taws lossis tawg, thiab cov haujlwm PCB yuav tsum muab tso rau ntawm PCB qhov chaw txhawb nqa.

3.Tsis txhob co chaw nres tsheb rework, thiab maj mam txav mus

4.Tsis txhob chwv thaj chaw kub taub hau siab, txwv tsis pub koj yuav hlawv

5.Thaum muab, tsis txhob siv cov nplaim tawg, kua lossis kua roj nyob ze ntawm chaw nres tsheb kho

6.Tsis txhob sim kho qhov chaw nres tsheb rov ua haujlwm, txwv tsis pub nws yuav ua hluav taws lossis hluav taws xob

7.Electrical lub thawv muaj cov khoom ntim siab, tsis txhob sim rhuav tshem

8.Yog hais tias cov khoom siv hlau lossis kua dej poob rau hauv qhov chaw nres tsheb thaum nws ua haujlwm, tam sim ntawd tshem tawm lub hwj chim, tshem tawm lub hwj chim txuas kom txog thaum lub tshuab txias, tom qab ntawd tshem tawm cov khib nyiab, av; yog tias av tawm mus, muaj qhov ntxhiab tsw thaum rov tsim dua

9.Thaum cov cua kub tsis zoo lossis haus luam yeeb, txiav tawm lub hwj chim tam sim ntawd, thiab qhia cov kev pabcuam kev pabcuam kom kho nws yuav tsum tau txiav cov xov hluav taws xob ntawm lub thawv hluav taws xob thiab lub tshuab ua haujlwm, thiab yuav tsum tuav lub ntsaws, txwv tsis pub nws coj mus rau qhov tsis zoo, thiab tsis tsis ua haujlwm

10.Ntawm tias qhov chaw nres tsheb tsis txhob nyem lossis khiav hla lwm cov khoom siv hluav taws xob lossis hluav taws xob lossis kab txuas lus, thiab nws yuav ua rau lub tshuab ua haujlwm tsis raug lossis ua rau hluav taws lossis hluav taws xob

11. Ua ntej siv chaw nres tsheb rework, koj yuav tsum nyeem phau ntawv no kom zoo
