Cov Lus Qhia no yuav qhia koj yuav npaj siv li cas thiab 2D kab ke xoo hluav taws xob txhawm rau tshuaj xyuas BGA, nrog rau qee cov lus qhia seb yuav saib dab tsi thaum ua BGA X-Ray tshuaj xyuas koj yuav xav tau:

X-hluav taws xob muaj peev xwm tuav PCB

PCB

ESD lub cev

ESD lub dab teg

Cov khau zoo ESD.

Kauj ruam 1: Txheeb xyuas

Txheeb xyuas cov txheej txheem tshuaj xyuas ntawm cov neeg siv khoom cog lus. IPC-A-610 cov txheej txheem tshuaj xyuas rau chav kawm ntawm kev sib dhos yog ib qho ntawm cov txheej txheem tsis raug. Tsis tas li, saib IPC-7095 kom tau txais koj tus kheej qhov kev lees paub rau X-Ray Kev Tshuaj Xyuas ntawm BGAs.

Kauj Ruam 2: Tshem tawm PCB

Tshem PCB los ntawm lub hnab tiv thaiv zoo li qub. Nco ntsoov tias koj tau ua haujlwm zoo thaum tuav cov khoom siv hluav taws xob raws li EOS/ESD 2020 cov lus qhia lossis cov txheej txheem hauv tuam txhab.

Kauj ruam 3: Npav

Txheeb xyuas thaj tsam ntawm kev txaus siab thiab kos nrog daim ntawv rov ua haujlwm ntawm thaj chaw lossis khoom siv uas txaus siab. Nws yuav pab nrhiav qhov chaw..

Kauj Ruam 4: Thauj khoom BGA rau hauv X-ray Chamber

Thauj lub PCB rau hauv chav xoo hluav taws xob. Nco ntsoov txhua qhov kev tiv thaiv tsim nyog tau ua ua ntej siv lub tshuab xoo hluav taws xob. Pib xoo hluav taws xob. Nco ntsoov tias muaj qhov sib txawv txaus hauv koj cov duab kom txhua qhov voids thiab qhib tau pom.

Siv lub tshuab pointer laser hauv txoj kab xoo hluav taws xob, tswj lub rooj xws li thaj tsam ntawm kev txaus siab tshwm sim ntawm tus neeg teb xov tooj interface x-ray screen.

Kauj Ruam 5: Kev Koom Tes ntawm Digital BGA X-ray Cov Ntaub Ntawv

Koj yuav zoo li yuav siv ntau cov duab ntawm BGA los ntawm ntau lub kaum ntse ntse, yog li ua kom ntseeg tau tias daim nplaub tshev rau ob qho duab thiab yees duab tau teeb tsa ua ntej tua. Muab cov duab tso rau hauv daim nplaub tshev tseeb rau kev khaws cia nrog txoj haujlwm.

Kauj Ruam 6: Tshawb xyuas cov duab BGA X-ray

Nrhiav BGA xav tau kev tshuaj xyuas xoo hluav taws xob. Txheeb xyuas qhov ua txhaum xws li luv, qhib, txuas hniav thiab zoo li no. Siv cov snapshots lossis cov vis dis aus ntawm cov tsis sib xws no

Txheeb xyuas tag nrho BGA tom qab ntawd nthuav dav rau "taug kev" ib puag ncig thaj chaw ntaus ntawv. Them daim ntawv ceeb toom kom zoo ib yam pob, sib npaug sib npaug, cov kab laug sab luv, cov khoom sib dhos thiab lwm yam tsis xws luag.

Zoom hauv los tshuaj xyuas qhov sib xws ntawm qhov ntau thiab tsawg ntawm pob, qhov sib txawv ntawm cov pob, qhov khoob thiab lwm yam teeb meem. Txheeb xyuas ib feem ntawm cov duab pob ntawm BGA hauv cov qauv tsim kom ntseeg tau tias koj npog tag nrho cov pob.

Kauj ruam 7: Qhib-Up

Thaum kuaj BGA xoo hluav taws xob tiav, tshem tawm PCB los ntawm chav xoo hluav taws xob. Tshem daim ntawv rov ua dua tshiab, tom qab ntawd tso rov qab rau hauv hnab tiv thaiv zoo li qub.
