Raws li cov PCB siv los ntawm ntau yam khoom siv hluav taws xob dhau los ua ntau dua thiab ntse dua, tshawb pom qhov ua txhaum ntawm PCB rov qab siv tus kheej tsis yog qhov nyuaj tab sis kuj tseem muaj kev ntseeg tau tsawg. AUTOMATIC tester rau PCB rov qab raws li PLD qhia hauv daim ntawv no tuaj yeem txhim kho kev ua haujlwm tau zoo thiab ua kom ntseeg tau tias muaj kev ntseeg tau.

Nrog kev txhim kho sai ntawm cov thev naus laus zis thev naus laus zis, tau siv dav hauv ntau hom khoom siv hluav taws xob tsim cov ntawv luam tawm Circuit Board (PCB) tau nce ntau, cov neeg ua haujlwm tshaj lij yuav tsum tau txiav txim siab sai tom qab ntawm luv Circuit Court, qhib kev ua txhaum lossis kho ntau dhau ntawm kev tiv thaiv, yog tias vam khom rau kev tshawb nrhiav dag yog qhov nyuaj heev, thiab kev ntseeg tau qis, yog li lub rooj sib tham hauv Circuit Court rov qab ua kom muaj kev thov ntau ntawm kev sim tsis siv neeg. Hauv daim ntawv no, ib txoj hauv kev ntsuas qhov ntsuas tsis siv neeg rau PCB rov qab raws EPM7128 tswj kev xaiv ntau txoj kev hloov pauv ADG732 tau thov, thiab nws tau muab rau. Nws tau ua pov thawj tias txoj kev xeem tau nrawm thiab muaj txiaj ntsig zoo tom qab siv rau PCB kev sim rov qab.

Txheej txheem kho vajtse muaj pes tsawg leeg

Cov txheej txheem txheej txheem ntawm kev ntsuas tsis siv neeg tau qhia hauv daim duab 1, uas suav nrog microcomputer, USB npav DIO interface daim npav, PLD tswj thaiv, ntau txoj hauv kev xaiv hloov, ntsuas kev sib tw thiab lwm yam.Lub kaw lus tuaj yeem sim qhib sai thiab luv luv ua txhaum ntawm ib leeg, ob npaug thiab ntau txheej PCB thaub qab.

Microcomputers tsis muaj qhov tshwj xeeb xav tau, thiab feem ntau tuaj yeem siv computer zoo tib yam. Cov txheej txheem txheej txheem txais yuav pheej yig USB-7802ADIO kev tswj hwm tus qauv tsim los ntawm Hongtop Measurement and Control Technology Co., LTD. Cov tswv yim thiab tso tawm qhov hluav taws xob yog 0 ~ 5V, nyob rau hauv kab nrog USB npav +5V tus qauv. Usb-7802a yog 32-channel thoob ntiaj teb digital TTL qib tswv yim/tso tawm pawg thawj coj, nrog 4 8-ntsis digital cov chaw nres nkoj thiab 4 8-ntsis cov lej tso tawm latch chaw nres nkoj, tag nrho ntawm 32 nkag thiab 32 tawm; Muab win95/98/2000/NT hauv qab qhov kev xeem thiab qhov txuas txuas txuas txuas (DLL).Txij li nws yog lub tsheb npav USB, USB raws tu qauv tau txiav txim siab qhov chaw nyob ntawm pawg thawj coj.
