Rau E-tester koob cim ntawm pcb

Nyob rau hauv tus txheej txheem ntawm PCB board manufacturing, thiaj li yuav xyuas kom meej tias tag nrho cov zoo raws li qhov yuav tsum tau, nws yog tsim nyog los ntsuam xyuas cov kev ua tau zoo ntawm hluav taws xob tsis thiab raws sij hawm nrhiav tau cov teeb meem txawv txav xws li luv luv-circuit resistance. Txhim kho PCB ntau lawm tawm los, txo qhov tsis tsim nyog poob. Kev ntsuam xyuas hluav taws xob yog txhawm rau ntsuas qhov tam sim no thiab qhov hluav taws xob ntawm cov khoom siv hluav taws xob txuas nrog lub rooj tsav xwm hauv Circuit Court kom paub tseeb tias qhov kev ua haujlwm ntawm lub rooj tsavxwm yog qhov qub. Yog hais tias lub clamping ceev ntawm lub fixture yog siab dhau lawm, qhov ceev ntawm lub flying koob sojntsuam yog ceev heev, thiab lub siab loj heev, lub xeem koob qhab nia yuav nyob rau hauv lub PCB board.

Needle mark teeb meem yog hais txog qhov teeb meem uas lub xeem koob yuav ua rau cov cim ntawm lub phaj tooj liab thaum lub sij hawm pcb kev ntsuam xyuas hluav taws xob. Qhov no yuav ua rau muaj kev hloov pauv ntawm lub peev xwm saum npoo ntawm lub rooj tsavxwm tooj liab, yog li cuam tshuam rau qhov tseeb ntawm cov khoom siv hluav taws xob hauv Circuit Court board. Txawm hais tias koob cim teeb meem feem ntau tshwm sim hauv kev kuaj hluav taws xob pcb, peb tuaj yeem zam lawv los ntawm qee txoj kev.

Tam sim no, txoj kev kho saum npoo feem ntau rau PCB boards suav nrog HASL thiab kub plating. Cov kev kho mob sib txawv yog cuam tshuam los ntawm cov khoom sib txawv, thiab lawv lub peev xwm los tiv thaiv hluav taws xob ntsuas kev ntsuas kev ua tau zoo kuj txawv. Kev ntsuas hluav taws xob PCB suav nrog kev sim koob txaj thiab kev sim rab koob ya. Thaum lub sij hawm xeem txheej txheem, kev ua tau zoo ntawm cov ntawv luam tawm Circuit Board tau cuam tshuam. Kev kho koob tshuaj yog ncaj qha ntsig txog kev kho saum npoo ntawm lwm qhov chaw kuaj. Qhov siab tshaj plaws ntawm koob kos npe ntawm HASL board yuav tsum tsawg dua 70um. Cov yam tseem ceeb uas cuam tshuam rau cov cim muaj xws li kev sojntsuam qauv, cov khoom siv, thiab txoj kev tswj xyuas.

Thaum lub sij hawm ntsuas hluav taws xob, nws yog ib qho tsim nyog yuav tsum tau tswj hwm qhov tsis sib xws xws li koob nqa qhov siab, lub cev muaj zog stepper, subdivision tsis, thiab pib ceev. Qhov kev sim no tau ua rau kev txo qis ntawm lub micro siab sensor ntawm lub tshuab sojntsuam, tab sis vim muaj kev cuam tshuam ntawm lub siab sensor, cov txheej txheem tsis tuaj yeem tswj tau thaum lub sijhawm sojntsuam, ua rau muaj ntau yam kab mob loj heev uas tsis tuaj yeem ua tau raws li kev soj ntsuam kev lag luam. Qhov kev sojntsuam kev sojntsuam cov qauv no tsis tuaj yeem ua tiav kev tswj xyuas zoo. Tam sim no, txoj kev tswj hwm qib siab dua tuaj yeem teeb tsa lub laser sensor ntawm qhov ntsuas ntsuas kom paub meej tias tsim nyog tswj cov koob cim.

Txhawm rau txhawm rau txhawm rau txheeb xyuas qhov teeb meem ntawm rab koob cim tau tsim thaum lub sij hawm ya davhlau soj ntsuam txheej txheem, peb tuaj yeem tsim cov phenomenon thiab thaum kawg txiav txim siab txog cov txheej txheem ntawm kos cim. Nyob rau tib lub sijhawm, peb tuaj yeem tswj tau qhov kev sojntsuam nrawm, txav nrawm, thiab qhov tob ntawm qhov vuam pad rauv chim ntawm qhov kev sojntsuam ya. Cov khawb yog cuam tshuam los ntawm kev siv rab phom tas li, muaj qhov tseem ceeb ntawm cov ntsiab lus ntsuas ntsuas hauv kab. Cov hauv paus ntsiab lus ntawm rab koob yog board thickness, rab koob nqa qhov siab, thiab sojntsuam txav ceev. Nws yog ib qho tsim nyog yuav tsum rov xav txog qhov tseem ceeb ntawm kev nqa qhov siab thiab kev txav nrawm tom qab lub rooj tsavxwm kom daws tau qhov teeb meem ntawm rab koob.

Tam sim no, kev sojntsuam ya davhlau suav nrog rab koob zoo li rab koob, rab koob zoo li rab koob, thiab rab koob tsis muaj zog, nrog ntau hom koob tsim cov koob sib txawv raws li tib yam.

Kev daws qhov ntsuas hluav taws xob ntsuas cov cim ntawm cov ntawv luam tawm Circuit Court yuav tsum muaj txheej txheem nyuaj uas yuav siv rau ntau yam. Los ntawm kev siv cov kev tiv thaiv tsim nyog, peb tuaj yeem txhim kho qhov zoo thiab kev ua tau zoo ntawm cov ntawv luam tawm Circuit Board thaum tswj kev tsim khoom thiab kev ntseeg tau.
