Kuyilo lwe-PCB kunye nemveliso yokugqibela ye-PCB, I-PCB Assembly ikwayinto ebaluleke kakhulu, engabandakanyi kuphela umgangatho webhodi ye-PCB, kodwa ichaphazela neendleko zemveliso ye-PCB. Ungaqinisekisa njani ukuba ibhodi ye-PCB esemgangathweni, indibano esengqiqweni nesebenzayo, ukonga izinto ezingavunyelwanga, inkampani yemveliso ibambelela kubaluleke kakhulu ekusombululeni ingxaki.

1. Imowudi yoqhagamshelo lweCollage

Zimbini iindlela zekhonkco zePCB, enye yiV-cut, enye ikhonkco lomngxunya wesitampu. I-V-cut ngokubanzi ilungele i-PCB enemilo yoxande, ebonakaliswa ngococeko emva kokwahlukana kunye nexabiso eliphantsi lokuqhubekeka, ke kuyacetyiswa ukuba uyisebenzise kuqala. Umngxuma wesitampu ngokubanzi ulungele ukuhlangana okungaqhelekanga kwepleyiti, umzekelo, ubume besakhelo sepleyiti ye-MID “L” ihlala yamkela imo yekhonkco yemingxuma yesitampu yokuhlanganisa ipleyiti.

2. Inani lekholaji:

Ubungakanani bebhodi iphela kufuneka ibalwe ngokobungakanani bebhodi enye yePCB. Ubungakanani bebhodi iphela akufuneki bugqithe kubungakanani obukhulu bePCB (ubude bebhodi yePCB mabungabi ngaphezu kwe250mm). Iibhodi ezininzi kakhulu ziya kuchaphazela ukuchaneka kwendawo yebhodi kunye nokuchaneka kwe-chip. Ngokubanzi, ibhodi ephambili yeklasi ye-MID ziibhodi ezi-2, kwaye ibhodi encinci yebhodi yezitshixo kunye nebhodi yeLCD ayikho ngaphezulu kweebhodi ezi-6. Ibhodi encinci yommandla okhethekileyo imiselwe ngokwemeko ethile.

3, iimfuno umngxuma bar link ikhonkco

Kwi-PCB kaMoses, inani lemivalo yekhonkco kufuneka ilunge, ngokubanzi imivalo ye-2-3, ukuze amandla e-PCB akwazi ukuhlangabezana neemfuno zenkqubo yemveliso, kwaye angophuli ngokulula. Xa ibha yekhonkco iyilelwe, kuye kufuneke ukuba kuyilwe ubude be-4-5mm, umngxunya ongagungqiyo, ubukhulu ubukhulu ngokubanzi bungu-0.3mm-0.5mm, isithuba phakathi kwemingxunya si-0.8-1.2mm;

Icandelo lenkqubo

Xa ibhodi ubukhulu becala, indawo yebhodi yomda ilinganiselwe, isidingo sokwandisa umda wenkqubo, esetyenziselwa ukuhambisa ibhodi ye-SMT ye-SMT, ngokubanzi i-3-5mm. Ngokubanzi, umngxunya wokubekwa kwindawo nganye uyongezwe kwikona nganye yomda wenkqubo, kwaye iindawo zokubekwa ezibonakalayo zongezwa kwiikona ezintathu ukomeleza ukubekwa komatshini.
