NezveDIP zvishandiso, PCB vanhu vamwe havasvipi gomba rinokurumidza!
DIP ndeye plug-in.Machipisi akaputirwa nenzira iyi ane mitsara miviri yemapini, ayo anogona kubatanidzwa zvakananga kune chip sockets ane DIP chimiro kana welded kune welding zvinzvimbo zvine nhamba yakafanana yemakomba.Zviri nyore kuona PCB bhodhi perforation welding, uye inoenderana zvakanaka nebhodhi reamai, asi nekuda kwenzvimbo yekurongedzera uye ukobvu hwakakura, uye pini mukuita kwekupinza nekubvisa iri nyore kukuvara, kusavimbika.
DIP ndiyo inonyanya kufarirwa plug-in package, iyo application range inosanganisira standard logic IC, memory LSI, microcomputer circuits, etc. Diki profile package (SOP), yakabva kuSOJ (J-type pin small profile package), TSOP (diki diki. profile package), VSOP (diki kwazvo profile package), SSOP (yakaderedzwa SOP), TSSOP (yakaonda yakaderedzwa SOP) uye SOT (diki profil transistor), SOIC (diki profil integrated circuit), nezvimwe.
- Iyo PCB package hole yakakura kupfuura mudziyo
PCB plug-in maburi uye mapaketi epini epakeji anodhirowa zvinoenderana nezvinodiwa.Nekuda kwekudiwa kwekuputirwa nemhangura mumakomba panguva yekugadzira ndiro, kushivirira kwese kuri kuwedzera kana kubvisa 0.075mm.Kana iyo PCB yekurongedza gomba yakakurisa kupfuura pini yechishandiso chemuviri, zvinotungamira mukusunungurwa kwechishandiso, tin isina kukwana, welding yemhepo uye mamwe matambudziko emhando.
Ona mufananidzo uri pazasi, uchishandisa WJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) pini yemudziyo ndeye 1.3mm, PCB yekurongedza gomba i1.6mm, aperture yakakura kwazvo inotungamira kune over wave welding space time welding.
Yakanamatira kumufananidzo, tenga WJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) zvikamu maererano nezvinodiwa zvekugadzira, pini 1.3mm yakarurama.
- PCB package hole idiki pane mudziyo
Plug-in, asi ichaita gomba hapana mhangura, kana iri imwe chete uye kaviri mapaneru anogona kushandisa nzira iyi, imwe chete uye kaviri mapaneru ari kunze magetsi conduction, solder inogona conductive;Iyo plug-in gomba ye multilayer board idiki, uye PCB board inogona chete kugadziriswa kana iyo yemukati layer iine magetsi conduction, nekuti yemukati layer conduction haigone kugadziriswa nekugadzirisa zvakare.
Sezvinoratidzwa pamufananidzo uri pasi apa, zvikamu zveA2541Hwv-3P_A2541HWV-3P (CJT) zvinotengwa maererano nezvinodiwa zvekugadzira.Pini iri 1.0mm, uye PCB yekuvharisa pad gomba iri 0.7mm, zvichikonzera kutadza kuisa.
Izvo zvikamu zveA2541Hwv-3P_A2541HWV-3P (CJT) zvinotengwa maererano nezvinodiwa zvekugadzira.Iyo pini 1.0mm ndeyechokwadi.
- Pakeji yepini spacing inosiyana nepakati pemudziyo
Iyo PCB yekuisa chisimbiso padhi yeDIP mudziyo haingove neyakavhurika yakafanana nepini, asi inodawo chinhambwe chakafanana pakati pemakomba epini.Kana nzvimbo iri pakati pemakomba epini uye mudziyo usingaenderane, mudziyo haugone kuiswa, kunze kwezvikamu zvine chinogadziriswa tsoka spacing.
Sezvinoratidzwa pamufananidzo uri pazasi, pini yegomba kureba kwePCB kurongedza i7.6mm, uye pini yepini chinhambwe chezvakatengwa zvinhu 5.0mm.Musiyano we2.6mm unotungamira kuti mudziyo usashande.
- Iwo maburi ekurongedza ePCB ari pedyo zvakanyanya
MuPCB dhizaini, kudhirowa uye kurongedza, zvinodikanwa kuti utarise kureba pakati pemakomba epini.Kunyangwe kana ndiro isina kugadzirwa inogona kugadzirwa, chinhambwe chiri pakati pemakomba epini idiki, zviri nyore kukonzeresa tin pfupi dunhu panguva yegungano ne wave soldering.
Sezvinoratidzwa mumufananidzo uri pasi apa, dunhu pfupi rinogona kukonzerwa nediki pini kureba.Pane zvikonzero zvakawanda zvekupfupika kwedunhu mune soldering tin.Kana kuungana kunogona kudzivirirwa pachine nguva pamagumo ekugadzira, chiitiko chezvinetso chinogona kuderedzwa.
- Dambudziko tsanangudzo
Mushure mekunge wave crest welding yechigadzirwa cheDIP, zvakaonekwa kuti pakanga paine kushomeka kwakakomba kwetin pane solder plate yegumbo rakagadzika re network socket, yaive yemhepo welding.
- Dambudziko rekuita
Nekuda kweizvozvo, kugadzikana kweiyo network socket uye PCB board kunowedzera kuipa, uye simba rechiratidzo chepini tsoka richaitwa panguva yekushandiswa kwechigadzirwa, izvo zvinozopedzisira zvatungamira kubatanidzwa kwechiratidzo chepini tsoka, inokanganisa chigadzirwa. kushanda uye kukonzera njodzi yekukundikana mukushandiswa kwevashandisi.
- Dambudziko rekuwedzera
Kugadzikana kwesokisi yetiweki kwakashata, kushanda kwekubatanidza kwepini yechiratidzo kwakashata, kune matambudziko emhando, saka zvinogona kuunza njodzi dzekuchengetedza kumushandisi, kurasikirwa kwekupedzisira kusingafungidzirwe.
- Kune matambudziko mazhinji ane chekuita neDIP mudziyo pini, uye akawanda mapoinzi akakosha ari nyore kufuratirwa, zvichikonzera yekupedzisira scrap board.Saka sei kukurumidza uye zvachose kugadzirisa matambudziko akadaro kamwe uye zvachose?
- Pano, kuungana uye kuongorora basa reCHIPSTOCK.TOP software yedu inogona kushandiswa kuita ongororo yakakosha pamapini emidziyo yeDIP.Zvinhu zvekuongorora zvinosanganisira nhamba yepini kuburikidza nemakomba, muganho wakakura wemapini eTHT, muganho mudiki weTHT pini uye hunhu hweTHT pini.Zvinhu zvekuongorora zvepini zvinovhara zvakanyanya matambudziko anogona kuitika mukugadzirwa kwemidziyo yeDIP.
- Mushure mekupedzwa kwePCB dhizaini, PCBA musangano wekuongorora basa rinogona kushandiswa kutsvaga kukanganisa dhizaini kumberi, kugadzirisa dhizaini inomalies isati yagadzirwa, uye kudzivirira matambudziko ekugadzira mukuita kwegungano, kunonoka kugadzira nguva uye kutambisa tsvakiridzo nemitengo yekusimudzira.
- Basa rayo rekuongorora gungano rine zvinhu zvikuru gumi uye 234 mitemo yekuongorora zvinhu zvakanaka, inovhara matambudziko ese angangoitika egungano, sekuongorora mudziyo, ongororo yepini, kuongororwa kwepadhi, nezvimwe, izvo zvinogona kugadzirisa akasiyana siyana ekugadzira mamiriro ayo mainjiniya asingakwanisi kufanofungidzira.
