Cov teeb meem yuav tsum tau them nyiaj mloog thaum ntsaws cov khoom hauvPCB Assemblytxheej txheem

Cov Cheebtsam ntawm PCB yuav tsum raug xaiv kom raug rau ntawm qhov chaw ua tau raws li qhov yuav tsum tau ua hauv Circuit Court.Nws yuav tsum tau muab sau tseg tias qhov rhiab heev voltage pib ntawm cov khoom uas muaj tib lub luag hauj lwm, cov qauv thiab cov khoom sib txawv yuav muaj qhov sib txawv loj.Yog li, cov teeb meem dab tsi peb yuav tsum tau them sai sai rau thaum tso cov khoom hauv PCB?

1. Txwv cov zis tam sim no kom tsis txhob xauv cov nyhuv ntawm CMOS Circuit Court

Cov nyhuv xauv yog qhov tshwj xeeb tsis ua haujlwm ntawm CMOS Circuit Court, vim tias muaj kab mob PNP transistor thiab NPN transistor nyob rau hauv cov qauv sab hauv ntawm CMOS Circuit Court, thiab lawv tsim cov kab mob parasitic PNPN thyristor qauv, yog li qhov ntsuas phoo ntawm CMOS Circuit Court yog. kuj hu ua "thyristor effect".

2. Siv cov ntxaij lim dej

Qee lub sij hawm xav tau ib txoj kab txuas ntev ntev ntawm CMOS Circuit Court thiab cov neeg kho tshuab kev sib cuag, uas ua rau muaj kev cuam tshuam ntawm electromagnetic cuam tshuam.Yog li, lim network yuav tsum xav txog.

3. RC network

Qhov twg nws muaj peev xwm ua tau, rau qhov kev nkag siab ntawm cov khoom siv bipolar, RC network tsim los ntawm cov resistors nrog cov tsis kam loj dua thiab cov capacitors nrog tsawg kawg 100pF tuaj yeem txo qhov cuam tshuam ntawm electrostatic paug.

4. Zam tus pin ntawm input raj rau CMOS raug tshem tawm.

Tsis txhob hnov ​​​​qab tias cov khoom siv kawg ntawm CMOS soldered ntawm lub rooj tsav xwm Circuit Court raug tshem tawm.Nyob rau tib lub sijhawm, nws yuav tsum tau them sai sai rau txhua qhov kev tawm tswv yim tsis tsim nyog ntawm CMOS ntaus ntawv tsis raug tso cai raug ncua.Vim tias ib zaug cov tswv yim raug tshem tawm, lub peev xwm tawm tswv yim yuav nyob rau hauv lub xeev tsis ruaj khov.

Cov saum toj no yog cov ntsiab lus ntawm cov teeb meem uas yuav tsum tau them sai sai rau hauv cov txheej txheem ntawm kev ntxig cov khoom rau hauv PCB.Kuv vam tias nws yuav pab tau koj.Yog xav paub ntxiv, thov mus saib peb lub vev xaib www.pcbfuture.com
