DIP Overview
DIP ndeye plug-in. Iyo chip inoshandisa nzira yekurongedza iyi ine mitsara miviri yepini, iyo inogona kutengeswa zvakananga pane chip socket ine DIP chimiro kana munzvimbo ye soldering ine nhamba yakafanana yemaburi ekutengesa. Hunhu hwayo ndehwekuti inogona kuona zviri nyore iyo perforation soldering yePCB board uye inoenderana zvakanaka nebhodhi reamai. Nekudaro, nekuda kwenzvimbo yayo yakakura yekurongedza uye ukobvu, uye mapini ari nyore kukuvadzwa panguva yeplug-in uye unplug process, kuvimbika kwakashata.
DIP ndiyo inonyanya kufarirwa plug-in package, uye huwandu hwemashandisirwo ayo hunosanganisira standard logic IC, memory LSI, microcomputer circuits, etc. Diki outline package (SOP). Yakatorwa SOJ (J-mhando yepini diki rondedzero pasuru), TSOP (yakatetepa pepa rekutaura pasuru), VSOP (diki diki rondedzero pasuru), SSOP (kunya SOP), TSSOP (yakaonda shrink SOP) uye SOT (diki ratidziro transistor), SOIC (diki rondedzero yakabatanidzwa yedunhu), nezvimwe.
DIP mudziyo dhizaini dhizaini kukanganisa
1. Hombe PCB pasuru gomba
Iyo plug-in gomba uye pasuru yepini gomba yePCB inodhirowa zvinoenderana neyakatsanangurwa bhuku. Munguva yekugadzira ndiro, gomba rinoda kuve rakaputirwa nemhangura, uye kushivirira kwakawanda kuri kuwedzera kana kubvisa 0.075mm. Kana iyo PCB pasuru gomba rakakura kupfuura pini yechishandiso chemuviri, zvinokonzeresa kuti mudziyo usununguke, kusakwana tinning, simbi isina chinhu, uye mamwe matambudziko emhando.
Ona mufananidzo uri pazasi: Pini yemuchina yeWJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) iri 1.3mm, uye gomba rePCB pasuru ndeye 1.6mm. Iyo hombe yegomba dhayamita inotungamira kune isina chinhu soldering panguva wave soldering.
Kuenderera mberi kubva pamufananidzo uri pamusoro, tenga WJ124-3.81-4P_WJ124-3.81-4P (KANGNEX) zvikamu maererano nezvinodiwa zvekugadzira, uye pini 1.3mm yakarurama.
2. Diki PCB pasuru gomba
- Gomba riri pane solder pad ye plug-in chikamu muPCB board idiki, uye chikamu hachigone kuiswa. Mhinduro chete yedambudziko iri ndeyekurisa dhayamita yegomba uye wozoisa plug, asi hapazove nemhangura mugomba. Iyi nzira inogona kushandiswa kana iri bhodhi rimwe chete kana mativi maviri. Iyo yekunze dhizaini yeimwe-sided kana kaviri-mativi bhodhi inoitisa magetsi, uye inogona kuve inoitisa mushure mekutengesa. Kana iyo plug-in gomba ye-multi-layer board iri diki uye mukati memukati uchifambisa magetsi, iyo PCB board inogona kungoitwa patsva, nekuti yemukati layer conduction haigone kugadziriswa nekuwedzera gomba.
Ona mufananidzo uri pazasi: Zvinoenderana nezvinodiwa zvekugadzira, zvikamu zveA2541Hwv-3P_A2541HWV-3P(CJT) zvinotengwa. Iyo pini ndeye 1.0mm, uye iyo PCB package pad gomba ndeye 0.7mm, izvo zvinoita kuti zvisaite kuisa.
Kuenderera mberi kubva pamufananidzo uri pamusoro, maererano nezvinodiwa zvekugadzira, zvikamu zveA2541Hwv-3P_A2541HWV-3P(CJT) zvinotengwa. Iyo pini 1.0mm ndeyechokwadi.
3. Chinhambwe chiri pakati pePCB pasuru mapini hachienderane nezvikamu
Mapakeji ePCB emudziyo weDIP haana chete dhayamita yegomba rakafanana nemapini, asiwo nzvimbo iri pakati pepini inofanira kuva chinhambwe chakafanana.
Kusapindirana pakati pepini buri spacing uye mudziyo uchaita kuti mudziyo utadze kupinza, kunze kwezvikamu zvine pini inogadziriswa spacing.
Ona mufananidzo uri pazasi: Iyo PCB pasuru yepini gomba spacing ndeye 7.6mm, uye chakatengwa chikamu chepini yepini spacing i5.0mm. Musiyano we2.6mm unoita kuti mudziyo usashande.
4. The PCB pasuru gomba spacing iri pedyo zvakanyanya, zvichiita kuti tini pfupi redunhu
Paunenge uchigadzira uye kudhirowa pasuru, unofanirwa kutarisisa kureba pakati pemapini maburi. Kunyangwe kana bhodhi risina chinhu rinogona kugadzirwa nepini diki gomba spacing, zviri nyore kukonzeresa tin pfupi yedunhu panguva yekuzunguza kwemafungu panguva yegungano.
Ona mufananidzo uri pazasi: Tin short circuit inogona kukonzerwa nepini diki chinhambwe. Pane zvikonzero zvakawanda zve wave soldering tin short circuit. Kana iyo yekupedzisira yekugadzira inogona kudzivirira kuungana kusati kwaitika, chiitiko chekuitika kwedambudziko chinogona kuderedzwa.
Mhosva chaiyo yerata isina kukwana papini yeDIP mudziyo
Dambudziko rekusawirirana pakati pehukuru hukuru hwezvinhu uye saizi yePCB pad gomba
Dambudziko rinotsanangurwa: Mushure mekunge chigadzirwa cheDIP chakatengeswa, zvakaonekwa kuti tin padhidhi yakagadzika yesokisi yetiweki yakanga isina kukwana, iyo yaive isina chinhu.
Impact yedambudziko: Kugadzikana kwesokisi yetiweki uye bhodhi yePCB ichaparara, uye pini yechiratidzo ichasimbiswa panguva yekushandiswa kwechigadzirwa, iyo inozopedzisira yakonzera kubatanidzwa kwepini yechiratidzo uye kukanganisa kushanda kwechigadzirwa. Pane njodzi yekukundikana panguva yekushandisa mushandisi;
Dambudziko rekuwedzera: Kugadzikana kwesokisi yetiweki kwakashata, kushanda kwekubatanidza kwepini yepini kwakashata, uye kune matambudziko ehutano. Naizvozvo, inogona kuunza njodzi dzekuchengetedza kune vashandisi, uye kurasikirwa kwekupedzisira kusingafungidzirwe.
zvinoshamisapcb DFM Services gungano rekuongorora rinotarisa mapini emudziyo
wonderfulpcb DFM Services gungano rekuongorora basa rine kuongorora kwakakosha kwepini yeDIP madivayiri. Zvinhu zvekuongorora zvinosanganisira nhamba yemapini epaburi, THT pini muganho, THT pini muganho, uye THT pini zvivakwa. Zvinhu zvekuongorora zvepini zvinovhara zvakanyanya matambudziko angangoitika mudhizaini yepini yeDIP zvishandiso.
Mushure mekunge dhizaini yapera, shandisa inoshamisapcb DFM Services gungano ongororo kuti uwane kukanganisa kwedhizaini kumberi uye kugadzirisa dhizaini anomalies pamberi pekugadzirwa kwechigadzirwa. Inogona kudzivirira matambudziko ekugadzira panguva yegungano, kunonoka kugadzira nguva, uye kutambisa R&D mutengo.
