1. Qhov tsim nyog ntawm PCBA Conformal Txheej
Qhov "peb" ntawm cov tsoos "peb pov thawj" yog hais txog cov dej tsis haum, pwm tsis kam, thiab tshuaj tsuag ntsev. Txawm li cas los xij, vim tias qhov zoo tshaj plaws thiab tsis kub tsis kam ntawm Conformal Txheej thiab tsim cov pob tshab tiv thaiv zaj duab xis rau saum npoo ntawm PCBA tom qab kho, nws kuj muaj qee yam haujlwm rau kev tiv thaiv plua plav, rwb thaiv tsev kom muaj zog, tiv thaiv sulfurization, thiab lwm yam tshuaj tiv thaiv corrosion. Txawm tias siv cov txheej txheem tshwj xeeb thiab cov txheej txheem tshwj xeeb tuaj yeem ua tiav cov dej tsis zoo.
Cov khoom lag luam thaum ntxov tau txais kev saib xyuas zoo los ntawm cov neeg siv, feem ntau ua haujlwm hauv tsev nrog kev tswj kub thiab av noo, thiab ib puag ncig zoo, yog li tsis muaj kev thov rau PCBA kev tiv thaiv. Tab sis nrog cov kev hloov pauv hauv daim ntawv thov kev xav tau thiab kev txhim kho ntawm cov cuab yeej siv kho vajtse, ntau thiab ntau cov khoom tau nce mus txog qhov chaw, thiab qhov chaw ua haujlwm yog qhov nyuaj thiab hnyav. Dampness, plua plav, ntsev pos huab, vulcanization, thiab lwm yam yuav dhau los ua cov neeg tua neeg zais uas cuam tshuam cov khoom lag luam. Txhawm rau txhim kho qhov kev hloov pauv ib puag ncig ntawm cov khoom lag luam thiab txhim kho nws txoj kev ntseeg tau, piv rau kev txhim kho qhov chaw ua haujlwm, ua kom cov khoom tsim kho kom zoo dua qub, lossis ntxiv dag zog rau kev soj ntsuam cov khoom, cov txheej txheem ntawm PCBA yog tus nqi siab heev - kev xaiv zoo, uas feem ntau ua tiav cov nqi qis, kev ua haujlwm siab, tsis tshua muaj txheej txheem nyuaj, thiab kev ua haujlwm zoo sib xws.
Tab sis PCBA's kuj muaj qhov tsis zoo.
Ib qho yog qhov muaj peev xwm hloov pauv siab - qhov ntsuas qhov ntsuas hluav taws xob tsis zoo lossis qhov ntsuas hluav taws xob microwave nrog cov impedance siab, ua rau txo qis hauv Circuit Court rhiab heev lossis kev ua haujlwm.
Qhov thib ob, tom qab ib lub sij hawm ntawm daim ntawv thov, ib tug me me ntawm ib tug me ntsis irritating tsw yuav evaporate los ntawm conformal txheej xim.
Thib peb, thaum PCBA ua haujlwm tsis zoo thiab yuav tsum tau kho, vim qhov nyuaj ntawm kev tshem tawm cov xim txheej txheej, qhov ua tau zoo thiab kev ua tiav ntawm kev kho PCBA tau raug txo qis rau qee yam.
2.Yuav ua li cas xaiv qhov tsim nyog Conformal Txheej raws li koj tus kheej xav tau?
Nws tsuas yog nyob ntawm cov khoom xav tau thiab batch loj. Yog tias qhov kev tiv thaiv yuav tsum muaj siab tshwj xeeb, cov khoom tsim tawm me me, thiab tus nqi tsis rhiab, Parylene tuaj yeem txiav txim siab. Cov nyhuv tiv thaiv yog qhov zoo tshaj plaws, thiab nws tuaj yeem ua haujlwm ib txwm txawm tias soaked hauv dej. Qhov tsis zoo yog kev ua haujlwm tsawg, uas tsis haum rau kev tsim khoom loj. Yog tias kev tiv thaiv kev tiv thaiv yog qhov dav dav thiab tus nqi rhiab heev, UV hom Conformal Txheej tuaj yeem xaiv, uas muaj kev tiv thaiv zoo thiab tus nqi qis dua li hom hnyav thiab Parylene. Kev ua haujlwm ntau lawm kuj yog siab dua Parylene, ua rau nws tsim nyog rau ntau lawm.
