DIP Uhlolojikelele
I-DIP iyi-plug-in. I-chip esebenzisa le ndlela yokupakisha inemigqa emibili yezikhonkwane, ezingathengiswa ngokuqondile kwisokhethi ye-chip enesakhiwo se-DIP noma endaweni yokunamathisela enenombolo efanayo yezimbobo ze-solder. Izici zayo ukuthi ikwazi ukubona kalula ukufakwa kwe-perforation kwebhodi le-PCB futhi inokuhambisana okuhle nebhodi lomama. Kodwa-ke, ngenxa yendawo yayo enkulu yokupakisha nokuqina, futhi izikhonkwane zonakaliswa kalula ngesikhathi se-plug-in kanye nenqubo yokukhipha, ukwethembeka akulungile.
I-DIP iyiphakheji ye-plug-in edume kakhulu, futhi ububanzi bohlelo lwayo lokusebenza buhlanganisa i-logic evamile ye-IC, imemori ye-LSI, amasekhethi e-microcomputer, njll. Iphakheji yohlaka oluncane (SOP). I-SOJ esuselwe (uhlobo lwe-J-pin yephakeji elincane lohlaka), i-TSOP (iphakheji elincane lohlaka), i-VSOP (iphakheji yohlaka encane kakhulu), i-SSOP (ukuncipha i-SOP), i-TSSOP (i-SOP encane eshwabene) kanye ne-SOT (i-transistor yohlaka oluncane), i-SOIC (isifunda esincane esihlanganisiwe sohlaka), njll.
Amaphutha edizayini yokuhlanganisa idivayisi ye-DIP
1. Imbobo enkulu yephakheji ye-PCB
Imbobo ye-plug-in kanye nephinikhodi yephakheji ye-PCB zidwetshwa ngokuya ngebhuku lemininingwane. Phakathi nenqubo yokwenza amapuleti, imbobo idinga ukufakwa ngethusi, futhi ukubekezelela okuvamile kuhlanganisa noma kususe 0.075mm. Uma imbobo yephakheji ye-PCB inkulu kunephinikhodi yedivayisi ephathekayo, izobangela ukuthi idivayisi ixege, ukuthayela okunganele, ukusoda okungenalutho, nezinye izinkinga zekhwalithi.
Bona isithombe esingezansi: Iphinikhodi yedivayisi ye-WJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) ingu-1.3mm, futhi imbobo yephakheji ye-PCB ingu-1.6mm. I-diameter yembobo enkulu iholela ekuhlanganisweni okungenalutho ngesikhathi sokufakwa kwamagagasi.
Ukuqhubeka kumfanekiso ongenhla, thenga izingxenye ze-WJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) ngokuya ngezidingo zokuklama, futhi iphinikhodi engu-1.3mm ilungile.
2. Imbobo encane yephakheji ye-PCB
- Imbobo kuphedi ye-solder yengxenye ye-plug-in ebhodini le-PCB incane, futhi ingxenye ayikwazi ukufakwa. Isixazululo kuphela sale nkinga ukukhulisa ububanzi bembobo bese ufaka ipulaki, kodwa ngeke libe khona ithusi emgodini. Le ndlela ingasetshenziswa uma ibhodi elinohlangothi olulodwa noma elinezinhlangothi ezimbili. Ungqimba lwangaphandle lwebhodi elinohlangothi olulodwa noma olunezinhlangothi ezimbili lusebenza ngogesi, futhi lungaqhutshwa ngemva kokuhlanganisa. Uma i-plug-in imbobo yebhodi enezingqimba eziningi incane futhi isendlalelo sangaphakathi sisebenza ngogesi, ibhodi le-PCB lingenziwa kabusha kuphela, ngoba ukuqhutshwa kwesendlalelo sangaphakathi akukwazi ukulungiswa ngokwandisa imbobo.
Bona isibalo esingezansi: Ngokwezidingo zokuklama, izingxenye ze-A2541Hwv-3P_A2541HWV-3P(CJT) ziyathengwa. Iphinikhodi ingu-1.0mm, futhi imbobo yephedi yephakheji ye-PCB ingu-0.7mm, okwenza kungenzeki ukulifaka.
Ukuqhubeka kulesi sibalo esingenhla, ngokwezidingo zokuklama, izakhi ze-A2541Hwv-3P_A2541HWV-3P(CJT) ziyathengwa. Iphinikhodi engu-1.0mm ilungile.
3. Ibanga phakathi kwamaphini ephakheji ye-PCB alifani nezingxenye
Amaphedi wephakheji we-PCB wedivayisi ye-DIP akagcini nje ngokuba nobubanzi bembobo obufanayo nezikhonkwane, kodwa futhi isikhala phakathi kwamaphini kufanele sibe ibanga elifanayo.
Ukungqubuzana phakathi kwesikhala sembobo yephini kanye nedivayisi kuzobangela ukuthi idivayisi ingakwazi ukufakwa, ngaphandle kwezingxenye ezinezikhala zephinikhodi ezilungisekayo.
Bheka umfanekiso ongezansi: Isikhala sembobo yephini yephakheji ye-PCB singu-7.6mm, futhi ingxenye ethengiwe yesikhala sembobo yephini ingu-5.0mm. Umehluko ongu-2.6mm wenza idivayisi ingasebenziseki.
4. Isikhala sembobo yephakheji ye-PCB sisondele kakhulu, okuholela ekusekeni okufushane kwethini
Lapho uklama futhi udweba iphakheji, udinga ukunaka ibanga phakathi kwezimbobo zephini. Ngisho noma ibhodi elingenalutho lingakhiqizwa ngesikhala esincane sembobo yephini, kulula ukubangela umjikelezo omfushane we-tin ngesikhathi se-wave soldering ngesikhathi somhlangano.
Bheka umfanekiso ongezansi: I-Tin short circuit ingase ibangwe ibanga elincane lephini. Kunezizathu eziningi ze-wave soldering tin short circuit. Uma ukuphela komklamo kungavimbela ukuhlangana kusengaphambili, izinga lokuvela kwenkinga lingancishiswa.
Ikesi langempela lethini elinganele kuphinikhodi yedivayisi ye-DIP
Inkinga yokungafani phakathi kosayizi wokhiye wento kanye nosayizi wembobo yephedi ye-PCB
Inkinga incazelo: Ngemva kokuthi umkhiqizo we-DIP udayisiwe, kwatholakala ukuthi ithini eliseceleni elingaguquki lesokhethi yenethiwekhi yayinganele kakhulu, okwakuyi-solder engenalutho.
Umthelela wenkinga: Ukuzinza kwesokhethi yenethiwekhi kanye nebhodi le-PCB kuzowohloka, futhi iphinikhodi yesignali izogcizelelwa ngesikhathi sokusetshenziswa komkhiqizo, okuzogcina kubangele ukuxhumeka kwephinikhodi yesignali futhi kuthinte ukusebenza komkhiqizo. Kukhona ingozi yokwehluleka ngesikhathi sokusetshenziswa komsebenzisi;
Isandiso senkinga: Ukuzinza kwesokhethi yenethiwekhi akulungile, ukusebenza kokuxhumeka kwephinikhodi kubi, futhi kunezinkinga zekhwalithi. Ngakho-ke, ingase ilethe izingozi zokuphepha kubasebenzisi, futhi ukulahlekelwa kokugcina akunakucatshangwa.
