Isakhiwo Izindlela Ezingcono Kakhulu: Ubuqotho Besiginali kanye Nokuphatha Okushisayo

Isakhiwo singenye yezinto ezibalulekile ekwakhiweni kwe-PCBA ukuze kuqinisekiswe ubuqotho besignali nokuphathwa okushisayo kwebhodi.Nazi ezinye izinqubo ezihamba phambili zesakhiwo ekwakhiweni kwe-PCBA ukuze kuqinisekiswe ubuqotho besignali nokuphathwa kokushisa:

Imikhuba Engcono Kakhulu Yobuqotho Besiginali

1. Isakhiwo Esinezingqimba: Sebenzisa ama-PCB anezendlalelo eziningi ukuze uhlukanise izendlalelo zesignali ezihlukene futhi unciphise ukuphazamiseka kwesignali.Amandla ahlukene, izendlalelo zomhlabathi kanye nezimpawu zokuqinisekisa ukuzinza kwamandla nobuqotho besignali.

2. Izindlela Zesiginali Ezimfushane Neqondile: Nciphisa izindlela zesiginali ngangokunokwenzeka ukuze unciphise ukubambezeleka nokulahlekelwa ekudluliselweni kwesignali.Gwema izindlela zesignali ezinde, ezigobile.

3. I-Differential Signal Cabling: Kumasiginali anesivinini esikhulu, sebenzisa ikhebula yesignali ehlukile ukuze unciphise i-crosstalk nomsindo.Qinisekisa ukuthi ubude bendlela phakathi kwamapheya ahlukene buyafana.

4. Indiza ephansi: Qinisekisa indawo eyanele yendiza yaphansi ukuze unciphise izindlela zokubuya zesignali futhi unciphise umsindo wesignali nemisebe.

5. ama-bypass kanye nama-decoupling capacitor: beka ama-bypass capacitor phakathi kwezikhonkwane zokuphakela amandla kanye nomhlabathi ukuze uzinze amandla kagesi.Engeza ama-decoupling capacitor lapho kudingeka khona ukunciphisa umsindo.

6. I-symmetry yokuhlukanisa okuhlukile kwesivinini esiphezulu: Gcina ubude bendlela kanye nokulinganisa kwesakhiwo kwamapheya ahlukene ukuze uqinisekise ukudluliswa kwesignali okulinganiselwe.

I-Thermal Management Best Practices

1. Idizayini eshisayo: Nikeza osinki okushisa abanele nezindlela zokupholisa zezingxenye zamandla aphezulu ukuze zikhiphe ukushisa ngempumelelo.Sebenzisa amaphedi ashisayo noma osinki bokushisa ukuze uthuthukise ukunqanyulwa kokushisa.

2. Isakhiwo sezingxenye ezizwelayo ku-thermal: Beka izingxenye ezizwelayo ku-thermal (isb, amaphrosesa, ama-FPGA, njll.) ezindaweni ezifanele ku-PCB ukuze unciphise ukwakheka kokushisa.

3. Isikhala sokungenisa umoya nesikhipha ukushisa: Qinisekisa ukuthi i-chassis noma indawo evalekile ye-PCB inezikhala ezanele nendawo yokukhipha ukushisa ukuze kuthuthukiswe ukujikeleza komoya kanye nokukhipha ukushisa.

4. Izinto zokudlulisa ukushisa: Sebenzisa izinto zokudlulisa ukushisa, njengamasinki okushisa nama-thermal pads, ezindaweni lapho ukukhishwa kokushisa kuyadingeka ukuze kuthuthukiswe ukusebenza kahle kokukhipha ukushisa.

5. Izinzwa Zezinga Lokushisa: Engeza izinzwa zokushisa ezindaweni ezibalulekile ukuze ugade izinga lokushisa le-PCB.Lokhu kungasetshenziswa ukuqapha nokulawula isistimu eshisayo ngesikhathi sangempela.

6. Ukulingisa okushisayo: Sebenzisa isofthiwe yokulingisa okushisayo ukuze ulingise ukusatshalaliswa okushisayo kwe-PCB ukusiza ukuthuthukisa isakhiwo kanye nomklamo oshisayo.

7. Ukugwema Izindawo Ezishisayo: Gwema ukunqwabelanisa izingxenye zamandla aphezulu ukuze uvimbele izindawo ezishisayo, okungase kuholele ekushiseni ngokweqile nasekuhlulekeni.

Kafushane, ukwakheka ekwakhiweni kwe-PCBA kubalulekile kubuqotho besignali nokuphatha okushisayo.Ngokulandela izinqubo ezihamba phambili ezichazwe ngenhla, ungathuthukisa ukusebenza nokuthembeka kwezinto zikagesi zakho ngokuqinisekisa ukuthi amasiginali adluliswa ngokulinganayo kuyo yonke ibhodi nokuthi ukushisa kulawulwa ngempumelelo.Ukusebenzisa ukulingisa kwesekethe namathuluzi okuhlaziya okushisayo phakathi nenqubo yokuklama kungasiza ukuthuthukisa isakhiwo nokuxazulula izinkinga ezingaba khona.Ngaphezu kwalokho, ukusebenzisana eduze nomkhiqizi we-PCBA kuyisihluthulelo sokuqinisekisa ukwenziwa ngempumelelo komklamo.

I-Zhejiang NeoDen Technology Co., Ltd. ibikhiqiza futhi ithumela kwamanye amazwe imishini emincane yokukhetha nendawo kusukela ngo-2010. Isebenzisa i-R&D yethu ecebile enokuhlangenwe nakho, ukukhiqizwa okuqeqeshwe kahle, i-NeoDen izuza idumela elihle kumakhasimende omhlaba wonke.

ngokuba khona komhlaba wonke emazweni angaphezu kwe-130, ukusebenza okuhle kakhulu, ukunemba okuphezulu nokuthembeka kwemishini ye-NeoDen PNP kuyenza ifanelekele i-R&D, i-prototyping yobungcweti kanye nokukhiqizwa kwenqwaba encane kuya kwemaphakathi.Sihlinzeka ngesixazululo sochwepheshe semishini yokumisa eyodwa ye-SMT.

Sikholelwa ukuthi abantu abakhulu nozakwethu benza i-NeoDen inkampani enhle futhi ukuzibophezela kwethu Ekusunguleni, Ukuhlukahluka kanye Nokusimama kuqinisekisa ukuthi i-SMT automation ifinyeleleka kuwo wonke umuntu wokuzilibazisa yonke indawo.
