Piav Flying Test of Circuit Court board hauv kev nthuav dav

Lub hauv paus ntsiab lus ntawm Circuit board board tus pin xeem yog yooj yim heev. Nws tsuas yog xav tau ob qhov kev tshuaj xyuas kom txav x, y thiab Z txhawm rau ntsuas ob qhov kawg ntawm txhua qhov Circuit Court ib tus los ntawm ib qho, yog li tsis tas yuav ua lwm qhov khoom siv kim. Txawm li cas los xij, vim qhov ntsuas qhov kawg, ntsuas nrawm yog qeeb heev, kwv yees li 10 ~ 40 cov ntsiab lus / feeb, yog li nws haum dua rau kev kuaj thiab cov khoom me me; Hais txog kev ntsuas ntom ntom, kev ntsuas koob ya tuaj yeem siv rau cov laug cam siab heev, xws li MCM.

Lub hauv paus ntsiab lus ntawm kev ntsuas rab koob: nws yog siv plaub qhov kev ntsuas los ntsuas qhov hluav taws xob hluav taws xob thiab kev tiv thaiv kev tiv thaiv qis (ntsuas qhov qhib Circuit Court thiab luv Circuit Court ntawm kab) rau lub rooj tsav xwm hauv Circuit Court, tsuav yog daim ntawv xeem tau tsim los ntawm tus neeg siv khoom qub thiab peb cov qauv kev tsim vaj tsev.

Tom qab qhov kev xeem, muaj plaub qhov laj thawj rau luv Circuit Court thiab qhib Circuit:

1. Cov neeg siv cov ntaub ntawv: tus ntsuas tsuas tuaj yeem sib piv, tsis txheeb xyuas

2. Cov kab ntau lawm: warpage, solder tsis kam thiab cov yam ntxwv tsis zoo ntawm PCB board

3. Txheej txheem hloov pauv cov ntaub ntawv: peb lub tuam txhab txais yuav cov qauv kev xeem engineering, thiab qee cov ntaub ntawv (ntawm) ntawm cov qauv kev tsim vaj tsev raug rho tawm

4. Yam khoom siv: teeb meem software thiab kho vajtse

Thaum peb tau txais lub rooj tsavxwm uas dhau peb qhov kev xeem thiab muab nws tso rau, peb ntsib qhov kev txhaws los ntawm qhov. Kuv tsis paub dab tsi ua rau nws. Peb yuam kev xav tias nws yog peb qhov kev sim, tab sis nws kuj tau xa tuaj. Qhov tseeb, muaj ntau yam laj thawj rau qhov hla qhov.

Muaj plaub qhov laj thawj rau qhov no:

1. Cov teeb meem tshwm sim los ntawm kev khawb: lub phaj yog ua los ntawm epoxy resin iav fiber. Tom qab drilling, muaj cov hmoov av seem hauv lub qhov, uas tsis tau ntxuav, thiab tooj liab tsis tuaj yeem tso tom qab kho tau. Feem ntau, peb yuav sim nws hauv qhov ntsuas ntsuas ya.

2. Cov teeb meem tshwm sim los ntawm kev tso tooj liab: lub sij hawm tso tooj liab luv dhau, lub qhov tooj liab tsis puv, thiab lub qhov tooj liab tsis puv thaum siv cov tin, ua rau muaj xwm txheej tsis zoo. (hauv tshuaj lom tooj liab tso tawm, muaj teeb meem hauv ib qhov txuas ntawm cov kua nplaum tshem tawm, tshem tawm cov roj alkaline, tshem tawm me me, ua kom nrawm dua thiab tso tooj liab, txhim kho tsis muaj qhov kawg, tshem tawm ntau dhau, thiab cov tshuaj uas seem hauv qhov tsis ntxuav kom huv. Cov kev sib txuas tshwj xeeb raug tshuaj xyuas kom ntxaws)

3. Circuit board vias xav tau tam sim no ntau dhau thiab tsis tau qhia ua ntej ntawm qhov xav tau los ua kom lub qhov tooj liab tuab. Qhov teeb meem no feem ntau tshwm sim thaum qhov tam sim no loj dhau los yaj lub qhov tooj liab tom qab fais fab tuag. Qhov tam sim no ntawm tus nqi theoretical tsis sib piv rau qhov tseeb tam sim no, ua rau muaj kev sib txuas ncaj qha ntawm lub qhov tooj liab tom qab lub zog qhib, ua rau tsis txuas ntxiv ntawm kev sib txuas, uas yuam kev xav tias qhov ntsuas tsis tau ua tiav.

4. Qhov tsis zoo tshwm sim los ntawm qhov ua tau zoo thiab thev naus laus zis ntawm SMT tin: lub sijhawm nyob ntev hauv lub cub tawg thaum lub sij hawm siv vuam ua rau yaj ntawm qhov tooj liab, uas ua rau muaj qhov tsis xws luag. Cov neeg koom tes tshiab tsis yog qhov tseeb hauv kev txiav txim cov khoom raws li kev tswj lub sijhawm, thiab ua yuam kev hauv cov khoom ntawm qhov kub, uas ua rau qhov tsis ua tiav ntawm qhov tooj liab yaj. Lub tshuab phaj tam sim no tuaj yeem ua qhov ntsuas ntsuas ya ntawm cov qauv, yog li yog phaj ua tseem tseem nrhiav tau 100% kev ntsuas koob ya kom tsis txhob muaj teeb meem pom hauv txhais tes ntawm phaj.

Xaus: los ntawm kev kawm, peb yuav paub ntau ntxiv txog cov ncauj lus me me ntawm kev ntsuas koob ya thiab paub mus qhov twg hauv peb txoj haujlwm.
