Kumsebenzi wam, ndiyaqinisekisa ukuba I-PCB Assembly ayinazo iimpazamo ezinjalo. Ngokudibanisa amakhulu ezinto ezincinci kunye, i-PCB yomelele kancinci kunokuba ungacinga. Ukuba ayiphathwanga kakuhle, unokufumana izikhalazo ezivela kubafakeli beenkqubo abanganelisekanga kuba iisekethe zisenokungasebenzi kakuhle.

Ngaba abayili be-PCB kufuneka bakhathalele ukuphatha i-PCB?

Amathuba kukuba, usenokungafuni ukwenza amakhulukhulu ee-PCBS uyilo lwakho. Abantu abaya kuqhagamshelana nale PCBS ngabahlanganisi, iinjineli zovavanyo, abafaki, kunye nabasebenzi bokugcina.

Inyaniso yokuba awuzukubandakanyeka kwinkqubo yasemva kwemveliso ayithethi ukuba ungonwabi malunga nokuphathwa kwePCB. Kubalulekile ukuqonda inkqubo echanekileyo yokuphatha i-PCB, kungenjalo inokubangela ukusilela kwesekethe.

Okubaluleke ngakumbi, abayili be-PCB kufuneka bayazi ngendima yabo ekuphuculeni ubeko lwe-PCB ukunciphisa iingxaki ezinxulumene nokuphathwa kwe-PCB. Into yokugqibela ofuna ukuyenza kukuphinda wenze i-PCB yakho esele ikho xa kufuneka ucelomngeni kwiprojekthi elandelayo.

Ukuphatha ngokungafanelekanga kwe-PCB kukhokelela njani kumonakalo

Ngokunikwa ukhetho, ndingathanda ukujongana ne-porcelain eyonakeleyo kuneengxaki ezibangelwa kukusingathwa kwePCB engafanelekanga. Ngelixa eyokuqala icacile, umonakalo obangelwa ziingxaki zokusingathwa kwePCB awunakuthelekiswa nanto. Ngokuqhelekileyo akukho miqondiso icacileyo yokuba i-PCB ayiyi kusebenza ngokufanelekileyo emva kokuthunyelwa.

Ingxaki eqhelekileyo iqatshelwe xa ukuphathwa ngokungakhathali kwePCBS kukusilela kwezinto ezisebenzayo ngenxa yokukhutshwa kombane ngombane (ESD). Oku kwenzeka xa kusingathwa i-PCBS kwindawo engakhuselekanga ye-ESD. Kwizinto ezibuthathaka ze-ESD, zingaphantsi kwe-3,000 volts ezifunekayo ukonakalisa isekethe yazo yangaphakathi.

Ukuba ujonga ngokusondeleyo kwi-PCB ene-welding, uya kubona ukuba i-solder encinci ibambe indibano yonyuso (SMD) kwi-pad. Izinto ezinje ngee-capacitors ze-SMD zinokubangela ukuba enye yeepads zayo iphule xa amandla oomatshini esetyenziswa ngokuhambelana nePCB.

Ngamanye amagama, xa uzama ukuyithatha i-PCB ngesandla esinye, ucinezela i-PCB ngokwakho. Oku kunokubangela ukuba i-PCB igobe kancinci kwaye inokubangela ukuba ezinye izinto ziwe pad yayo. Ukuthintela oku, ngumkhwa olungileyo ukuthatha i-PCB ngezandla zozibini.

Ii-PCBS zihlala zenziwa iipaneli ukunciphisa iindleko kunye nokuphucula ukusebenza kakuhle. Xa sele uhlanganisile, kufuneka uchithe iPCB. Nokuba baxhaswa ngamanqaku amancinci e-V, kusafuneka usebenzise amandla ukuze ubatsale. Le nkqubo inokonakalisa ngengozi ii-welds zamacandelo athile.

Akunqabile, kodwa ngamanye amaxesha ungakhathali, kwaye uyilahla i-PCB ngokungathi kukwisitya sase China. Impembelelo yequbuliso inokonakalisa izinto ezinkulu, ezinje ngee-electrolytic capacitors, okanye iipads.

Iindlela zokuyila ukunciphisa iingxaki zokuphatha i-PCB

Abayili be-PCB abalulutho kwaphela xa kufikwa kumba wokujongana neengxaki zokuphathwa kwe-PCB. Ukuya kuthi ga kwinqanaba elithile, ukumiliselwa kwesicwangciso esiliqili sokuyila kunokunceda ukunciphisa iziphene ezinxulumene nokuphathwa kwePCB.

Ukukhuselwa kwe-Electrostatic

Ukuthintela izinto ezinobuthathaka ukuba zonakaliswe yi-ESD, kuya kufuneka ukongeze izinto ezikhuselayo ukucinezela okwethutyana ngexesha lokukhutshwa kwe-ESD. IiVaristors kunye neZener diode zihlala zisetyenziselwa ukuphatha ukuphuma ngokukhawuleza kwe-ESD. Ukongeza, kukho izixhobo ezikhuselweyo ze-ESD ezinokubonelela ngokhuseleko olungcono kule nto.

Ukubekwa kwecandelo

Awunakho ukukhusela i-PCB kuxinzelelo loomatshini. Nangona kunjalo, unokuzinciphisa iingxaki ezinjalo ngokuqinisekisa ukuba izinto zibekwa ngendlela ethile. Umzekelo, uyazi ukuba ukubeka ii-capacitors ze-SMD kwindawo ehambelana nokuqhekeka kwamandla asetyenzisiweyo ngexesha lokwenza i-decarbonisation kwandisa umngcipheko wokwahlulwa kwe-solder.

Ke ngoko, kuya kufuneka ubeke i-SMD capacitor okanye iinxalenye ezifanayo ezinxulumene nomgca owaphukileyo ukunciphisa isiphumo samandla afakiweyo. Kwakhona, kuphephe ukubeka amacandelo kufutshane ugobile okanye umgca ijika le PCB, kwaye kuthintele ukubeka amacandelo kufutshane ulwandlalo lwebhodi.
