Iphaneli ye-PCBImigaqo kunye neendlela
1. Ngokweemfuno zenkqubo zeemveliso zendibano ezahlukeneyo, ubungakanani obukhulu kunye nobuncinci bephaneli kufuneka buqondwe ngokucacileyo. Ngokubanzi, i-PCB incinci kune-80x80mm kufuneka ibe yipaneli, kwaye ubungakanani obukhulu buxhomekeke kumthamo wokwenziwa komzi-mveliso. Ngamafutshane, ubungakanani be-PCB kufuneka bafezekise imfuneko yeIzixhobo zeSMTIzinto ezifanelekileyo, ezilungele ukuqhubekeka kwe-SMT ye-SMT kunye nokunceda ukuthatha isigqibo seBhodi yePCB.
2. Indibano kunye neqela elincinci kufuneka zifezekise iimfuno ze-DFM kunye ne-DFA, kwaye kwangaxeshanye iqinisekise ukuba iNdibano yePCB ilungisiwe kwaye ayikho kangako emva kokuba ibekwe kumgaqo. I-Groove eyahlulahluliweyo phakathi kweepaneli kufuneka ihlangane neemfuno zeflethi yomphezuluI-PCBAukuqhubekeka kwe-chip.
I-3. Kwipaneli ye-PCBuyilo. Ukusetyenziswa kwendawo yephaneli yaphambi kwexesha kunokunciphisa ubume bemfazwe kunye nokusetyenziswa ngexesha ukwahlukana kwebhodi, kwaye unciphise uxinzelelo kwizinto. Ubuncinci, zama ukungabeki ixabisoizintoOkulandelayokwicala lenkqubo.
4. Ubukhulu kunye nohlobo lwephaneli zisingathwa ngokweprojekthi ethile, kwaye uyilo lokubonakala lusondele kwisikwere kangangoko kunokwenzeka. Kucetyiswa ngamandla ukusebenzisa i-2 × 2 okanye i-3 × indlela yepaneli. Akucetyiswa ukudibanisa iin kunye neephaneli zang ukuba akunyanzelekanga;
5. Xa ulwalamano lomnxibelelanisi weBhodi ludlula phakathi kweebhodi ezidibeneyo ezininzi, iconjululwe ngokujikeleza i-dibang + icala lenkqubo yokuthintela umgangatho ombi womonakalo okanye inkqubo yokuphathaemva kwe-welding.
6. Emva koyilo lwepaneli, kufuneka uqinisekiswe ukuba umda wendawo ebonisa iBhodi enkulu ubude i-3.5mm ukusuka kumda weBhodi. SUKUFUMANA IINDAWO ZOKUGQIBELA ESIMISEBENZI
7. Xa ubukhulu beIbhodi yePCBIngaphantsi kwe-1.0mm, amandla eBhodi yePaneli yonke iya kuncitshiswa kakhulu (ubuthathaka) xa i-roove edibeneyo isetyenziselwa ukomelela, kuba i-v-cuting ye-vber isetyenziselwa ukwaphuka kwamandla. Ukuba ayixhaswa yi-jig, iya kuyichaphazela le nkqubo ingezantsi kwe-PCBA.
8. Xa kukhoIminwe yegolideKwi-PCB, ngokubanzi Beka iminwe yegolide ngaphandle kweBhodi kwicala lendawo engeyiyo i-splint. Umda womnwe wegolide awunakuqhutywa okanye ukwenziwa.
