Uyilo yenye yezinto eziphambili kuyilo PCBA ukuqinisekisa imfezeko uphawu kunye nolawulo thermal ebhodini.Nazi ezinye iindlela zoyilo ezilungileyo kuyilo lwePCBA ukuqinisekisa imfezeko yomqondiso kunye nolawulo lobushushu:
Iimpawu zeMfezeko zoMqondiso
1. Uyilo oluLayiweyo: Sebenzisa ii-PCB zomaleko amaninzi ukwahlula iileya ezahlukeneyo zesignali kunye nokunciphisa ukuphazamiseka kwesiginali.Ukwahlula amandla, umhlaba kunye neengqimba zomqondiso ukuqinisekisa uzinzo lwamandla kunye nokuthembeka komqondiso.
2. Iindlela zoMqondiso eziMfutshane nezithe Tye: Nciphisa iindlela zomqondiso kangangoko kunokwenzeka ukunciphisa ukulibaziseka kunye nelahleko ekuhanjisweni komqondiso.Ziphephe iindlela zomqondiso ezinde, ezigoso.
3. I-Differential Signal Cabling: Kwimiqondiso enesantya esiphezulu, sebenzisa i-differential signal cabling ukunciphisa i-crosstalk kunye nengxolo.Qinisekisa ukuba ubude bendlela phakathi kwezibini ezidityanisiweyo ziyahambelana.
4. Inqwelomoya ephantsi: Qinisekisa indawo yenqwelomoya eyaneleyo yokunciphisa iindlela zokubuya komqondiso kunye nokunciphisa ingxolo yomqondiso kunye nemitha.
5. I-bypass kunye ne-decoupling capacitors: i-capacitors beka i-bypass phakathi kwezikhonkwane zokubonelela umbane kunye nomhlaba ukuze uzinzise umbane wokubonelela.Yongeza i-decoupling capacitors apho kufunekayo ukunciphisa ingxolo.
6. I-Speed-Speed Different pair symmetry: Gcina ubude bendlela kunye ne-symmetry ye-layout ye-different pairs ukuqinisekisa ukuhanjiswa kwesignali elinganayo.
Ulawulo lwe-Thermal Best Practices
1. Uyilo lwe-Thermal: Ukubonelela ngeesinki zokushisa ezaneleyo kunye neendlela zokupholisa kumacandelo ombane aphezulu ukutshabalalisa ubushushu ngokufanelekileyo.Sebenzisa i-thermal pads okanye i-heat sinks ukuphucula ukuchithwa kobushushu.
2. Uyilo lwamalungu anovakalelo lwe-thermal: Beka amacandelo abuthathaka kwi-thermal (umzekelo, iiprosesa, ii-FPGAs, njl.njl.) kwiindawo ezifanelekileyo kwi-PCB ukunciphisa ukwakheka kobushushu.
3. Ukungena komoya kunye nendawo yokutshatyalaliswa kobushushu: Qinisekisa ukuba i-chassis okanye i-enclosure ye-PCB ine-vents eyaneleyo kunye nendawo yokutshatyalaliswa kobushushu ukukhuthaza ukujikeleza komoya kunye nokutshatyalaliswa kobushushu.
4. Izinto zokufudumeza ubushushu: Sebenzisa izinto zokuhambisa ubushushu, ezifana ne-heat sinks kunye ne-thermal pads, kwiindawo apho kufuneka ukutshatyalaliswa kobushushu ukuze kuphuculwe ukusebenza kakuhle kokushisa.
5. IiSensors zobushushu: Yongeza iinzwa zobushushu kwiindawo eziphambili ukujonga ubushushu bePCB.Oku kungasetyenziselwa ukubeka iliso kunye nokulawula inkqubo ye-thermal ngexesha langempela.
6. Ukulinganisa kwe-Thermal: Sebenzisa isofthiwe yokulinganisa i-thermal ukulinganisa ukuhanjiswa kwe-thermal ye-PCB ukunceda ukulungelelanisa uyilo kunye noyilo lwe-thermal.
7. Ukuphepha iindawo ezishushu: Gwema ukupakisha izixhobo zamandla aphezulu kunye ukuze uthintele iindawo ezishushu, ezinokukhokelela ekugqithiseni kwecandelo kunye nokusilela.
Isishwankathelo, uyilo kuyilo lwe-PCBA lubalulekile kumqondiso wemfezeko kunye nolawulo lobushushu.Ngokulandela iindlela ezingcono ezichazwe ngasentla, unokuphucula ukusebenza kunye nokuthembeka kwe-electronics yakho ngokuqinisekisa ukuba iimpawu zihanjiswa rhoqo kwibhodi kwaye ubushushu bulawulwa ngokufanelekileyo.Ukusebenzisa i-circuit simulation kunye nezixhobo zokuhlalutya kwe-thermal ngexesha lenkqubo yoyilo kunokunceda ukunyusa ukwakheka kunye nokusombulula imiba enokubakho.Ukongeza, intsebenziswano esondeleyo kunye nomvelisi wePCBA ngundoqo ekuqinisekiseni ukuphunyezwa ngempumelelo koyilo.
I-Zhejiang NeoDen Technology Co., Ltd. ibisenza kwaye ithumela ngaphandle koomatshini abancinci abancinci bokukhetha kunye nendawo ukusukela ngo-2010. Ukuthatha ithuba le-R&D yethu enamava, imveliso eqeqeshwe kakuhle, iNeoDen iphumelela igama elihle kubathengi behlabathi ngokubanzi.
kunye nobukho behlabathi kumazwe angaphezu kwe-130, ukusebenza okugqwesileyo, ukuchaneka okuphezulu kunye nokuthembeka koomatshini be-NeoDen PNP kubenza bagqibelele kwi-R&D, iprototyping yobuchwephesha kunye nemveliso yebhetshi encinci ukuya ephakathi.Sinikezela ngesisombululo sobungcali sesixhobo esinye sokumisa i-SMT.
Sikholelwa ukuba abantu abakhulu kunye namahlakani enza iNeoDen ibe yinkampani enkulu kwaye ukuzinikela kwethu kwiNguqu, iyantlukwano kunye noZinzo kuqinisekisa ukuba i-SMT automation iyafikeleleka kuye wonke umntu othanda ukuzonwabisa kuyo yonke indawo.
