4. Cov ntsiab lus ntawm BGA Chips Reball Automatic Optic Align

 

Tsis siv neeg kho qhov muag kho qhov muag yog qhov tshwj xeeb ntawm qee lub tshuab reballing uas tso cai rau kev sib haum xeeb ntawm BGA

nti thaum lub sij hawm reballing txheej txheem. Lub tshuab siv lub koob yees duab thiab cov duab paub txog cov algorithms siab heev

lub nti zoo kawg nkaus nyob rau hauv nruab nrab ntawm lub hom phiaj cheeb tsam, yog li xyuas kom meej tias cov tshiab solder npas yuav siv tau nyob rau hauv lub

txoj hauj lwm raug.

 

Zuag qhia tag nrho, kev sib xyaw ua ke ntawm BGA nti reballing thiab tsis siv neeg kho qhov muag sib dhos tshuab yog lub cuab yeej muaj zog rau

kho thiab tswj cov khoom siv hluav taws xob, thiab tuaj yeem pab txuas ntxiv lawv lub neej thiab txo cov nqi cuam tshuam

nrog hloov.

11. Kev Paub Txog

 

Vim li cas qhov kev sib txuas ntawm hauv av thiab lub casing ntawm PCB (txuas rau lub ntiaj teb) yog qhov tsim nyog? Nws puas tuaj yeem siv cov capacitors nkaus xwb?

Cov lus teb uas twb muaj lawm tsis yog, yog li cia kuv piav qhia.

1, Kev sib txuas ntawm Capacitor:Los ntawm qhov kev xav ntawm EMS (Electromagnetic Immunity), lub capacitor no nyob ntawm qhov chaw uas PE (Protective Earth) txuas nrog rau hauv av. Qhov kev sib txuas no tuaj yeem txo qhov kev cuam tshuam ntau zaus hauv Circuit Court los ntawm kev muab cov ntaub ntawv siv rau hauv av. Cov txiaj ntsig yog txhawm rau txhawm rau hloov pauv qhov sib txawv-hom kev sib txawv ntawm lub voj voog thiab qhov cuam tshuam. Qhov zoo tshaj plaws, GND yuav tsum txuas ncaj qha rau PE, tab sis qhov no yuav tsis yog ib txwm ua tau lossis nyab xeeb. Piv txwv li, GND generated tom qab rectifying 220V AC tsis tuaj yeem txuas nrog PE, uas cuam tshuam rau txoj kev tsawg zaus thiab tso cai rau cov teeb liab ntau dhau. Los ntawm qhov kev xav ntawm EMI (electromagnetic cuam tshuam), muaj hlau casing txuas nrog PE kuj tuaj yeem pab kom tsis txhob muaj hluav taws xob ntau zaus.

2.1M Resistor Siv:1M resistor yog ib qho tseem ceeb rau ESD (electrostatic paug) kuaj. Vim tias lub kaw lus no txuas PE thiab GND los ntawm lub capacitor (floating system), thaum kuaj ESD, tus nqi uas tau tsav mus rau hauv Circuit Court nyob rau hauv kev ntsuam xyuas raug tso tawm maj mam, nce lossis txo qib ntawm GND txheeb ze rau PE. Yog tias qhov hluav taws xob sib txuas ntau dua qhov kev zam rau qhov tsis muaj zog ntawm cov hluav taws xob hluav taws xob ntawm PE thiab Circuit Court, nws yuav tawm ntawm GND thiab PE, ua rau kaum rau pua pua ntawm amps ntawm PCB hauv ob peb nanoseconds. Qhov tam sim no txaus rau kev puas tsuaj rau ib qho Circuit Court vim EMP (electromagnetic pulse) los yog los ntawm ib lub cuab yeej txuas PE rau lub teeb liab ntawm qhov hluav taws xob tsis muaj zog. Txawm li cas los xij, raws li tau hais dhau los, qee zaum kuv tsis tuaj yeem txuas ncaj qha PE thiab GND. Nyob rau hauv tas li ntawd, kuv siv ib tug 1-2M resistor maj mam tso tus nqi thiab tshem tawm qhov voltage txawv ntawm ob. Tus nqi ntawm 1-2M raug xaiv raws li ESD tus qauv xeem; Piv txwv li, qhov siab tshaj qhov rov ua dua tau teev tseg hauv IEC61000 tsuas yog 10 zaug ib ob. Yog tias tsis yog tus qauv ESD tso tawm tshwm sim ntawm 1000 zaug hauv ib ob, ces qhov kev tawm tsam 1-2M yuav tsis txaus los tso cov nqi ntxiv.

3, Capacitance tus nqi:Tus nqi capacitance qhia los ntawm qhov kev kawm yog loj heev; Feem ntau, tus nqi ntawm 1nF yog qhov tsim nyog. Yog tias lub peev xwm loj dua yog siv rau hauv cov khoom siv xws li inverters thiab servo tsav nrog hloov zaus ntawm 8-16 kHz, muaj kev pheej hmoo ntawm hluav taws xob poob siab thaum cov neeg siv kov lub qhov rooj sab nraud. Lub peev xwm loj tuaj yeem qhia qhov tsis txaus ntawm lwm qhov kev tsim hluav taws xob, yuav tsum muaj kev nce hauv qhov peev xwm no los daws qhov kev sim EMC.

Thaum kawg, cia kuv hais ntxiv: PE tsis ntseeg! Ntau tus neeg siv khoom hauv tsev yuav tsis muab kev sib txuas PE siv tau, txhais tau tias koj tsis tuaj yeem nyob ntawm PE los txhim kho EMS lossis txo EMI. Qhov teeb meem no tsis yog tag nrho cov neeg siv khoom txhaum; lawv cov chaw ua haujlwm, cov chaw tsim khoom, thiab chaw ua haujlwm feem ntau tsis ua raws li cov qauv hluav taws xob, tsis muaj kev cog lus zoo. Yog li ntawd, nkag siab txog qhov tsis muaj kev ntseeg siab ntawm PE, Kuv siv ntau yam txuj ci los txhim kho lub Circuit Court tsis kam mus kuaj EMS.
