PLCC Package

Plastic Leaded Chip Carrier (PLCC) mapakeji anoita basa rakakosha mukugadzira zvigadzirwa zvemagetsi. Kunyangwe nekukwira kwemapakeji matsva eIC seQFP neBGA, maPLCC anoramba akakosha mune chaiwo maapplication, kunyanya mumasisitimu enhaka. Ichi chinyorwa chinopa tarisiro yakazara yePLCC mapakeji, inovhara dhizaini yavo, mhando, zvakanakira, maapplication, kugadzirisa, uye kugadzirisa.

Chii chinonzi PLCC Package?

PLCC mapakeji ari pamusoro-Mount Integrated Circuit (IC) mapakeji ane anotungamira anokwira kubva kumativi mana, akagadzirirwa kutengeswa paPCB. Vanopa sikweya kana rectangular chimiro uye inogona kuva chero kubva pamakumi maviri kusvika pamusoro pe20 mapini. Nzvimbo yepamusoro inowanzobatanidza hwindo rekuongororwa kwekuona kweIC.

Iyo PLCC package yakaunzwa seimwe yakasimba uye yakavimbika imwe nzira kune yekare IC mapakeji. Kwemakore, yakaona kushandiswa kwakapararira mumashandisirwo akasiyana siyana, kunyangwe mapakeji matsva seQFP neBGA ave akakurumbira. Nekudaro, maPLCC achiri kushandiswa mumidziyo yekare yemagetsi uye chaiwo maapplication emazuva ano uko maitiro avo akasiyana anobatsira.

Maitiro Ekushandisa Zvinonzwisisika PLCC Packaging

Kuti ushandise zvine musoro PLCC (Plastiki Inotungamira Chip Carrier) kurongedza mumagadzirirwo ako emagetsi, tanga nekuona kuti pasuru yacho inokodzera marongero uye dhizaini zvinodiwa zvePCB yako, kusanganisira kuongorora nhamba yepini uye zviyero. Chengetedza kutarisisa kwekupisa, sezvo maPLCC aine mashoma ekupisa kwekuita; shandisa yakakwana yekutonhodza mhinduro senge heatsinks kana yakagadziridzwa kufambisa kwemhepo kubata kupisa kupisa mune-yakakwirira-simba maapplication.

Shandisa hunyanzvi hwekusodha kuti udzivise zvinhu zvakajairika senge majoini anotonhora kana bhiriji, uye wedzera hwindo rekuongorora paPLCC package yekutarisa. Pamusoro pezvo, shandisa hunyanzvi hwekuyedza kuti uone kushanda kweIC pamberi uye mushure mekutengesa. Tumira PLCC mapakeji mumashandisirwo ayo maitiro avo anonyanya kubatsira, akadai semagetsi evatengi, masisitimu emotokari, zvishandiso zvekurapa, aerospace, uye maindasitiri emidziyo.

Kune madhizaini akaomarara kana kugadzirisa, funga kunyorera masevhisi ehunyanzvi kuti uve nechokwadi chekushandiswa kwakakwana uye kugadzirisa matambudziko. Izvi zvinokwidziridza hunyanzvi hwavo hwepamberi uye maturusi akasarudzika, kuve nechokwadi chekuti PLCC mapakeji anoshandiswa kune yavo yakazara kugona, kuwedzera mashandiro uye kuvimbika kwemidziyo yako yemagetsi.

Kugadzirisa uye Kugadziriswa kwePLCC Packages

Troubleshooting PLCC mapakeji anogona kunetsa nekuda kwedense pini kumisikidzwa. Heano matanho akadzama ekuongorora nekugadzirisa aya mapakeji:

1. Kuonekwa Kwekuona: Tanga nekunyatsoongorora pasuru yekukuvara kupi zvako kwemuviri, sekutsemuka, kushanduka kwemavara, kana mapini akabhenda. Iyi nhanho yekutanga inogona kubatsira kuona hurema huri pachena hungave huri kukonzera nyaya.
2. Kuedza IC: Shandisa michina yekuongorora yakasarudzika kuongorora mapini ega uye kuyedza mashandiro edunhu rakasanganiswa. Izvi zvinobatsira kuona kutadza chaiko kwemukati mukati me IC.
3. Kutarisa MaConnections: Ongorora majoini anotengeswa nekubatanidza pakati pePLCC nePCB kune nyaya dzakaita semajoini anotonhora, makatsemuka, kana kusabatana kwakashata kunogona kunge kuri kukanganisa dunhu.
4. Kutsiva Package: Kana iyo PLCC package yakatemwa kuve yakakanganisa, nyatso shandisa rework zvishandiso kuti desolder uye bvisa iyo yakaremara pasuru. Itsive neitsva, kuve nechokwadi chekuenzanisa uye yakachengeteka soldering.
5. Professional Repair: Kugadzirisa zvakanyanya kuoma kunoda hunyanzvi hwepamusoro uye maturusi ehunyanzvi, funga kutsvaga mabasa ekugadzirisa. Nyanzvi dzinogona kuve nechokwadi chekugadzirisa uye kwakaringana kugadzirisa, kuderedza njodzi yekumwe kukuvara.

Muenzaniso Kugadzirisa Scenario

Funga nezvechiitiko apo mota ECU ine PLCC package isingashande. Kuongorora kwekutanga kwekuona kunoratidza hapana kukuvara kwemuviri. Mudziyo wekuyedza wakasarudzika unoratidza IC yakashata. Kumwe kuferefeta kwezvibatanidza kunoratidza kuputika kwejoint solder. Iyo PLCC package inozonyatso paradzwa uye yotsiviwa neimwe nyowani. Iyi nzira yemaitiro inodzoreredza mashandiro eECU, ichiratidza kushanda kweakadzama kugadzirisa uye kugadzirisa maitiro ePLCC mapakeji.

Mashandisiro Ekushandisa PLCC Packaging Kuchengeta Mari muMagetsi Mapurojekiti

Kuti ushandise zvinobudirira kurongedza kwePLCC uye kuchengetedza mari mumapurojekiti ako emagetsi, tarisa pakushanda zvakanaka kwedhizaini uye kushandiswa kwezvinhu zvakanaka. Tanga nekuona kuti dhizaini yako yePCB inoenderana nehukuru hwepakeji yePLCC uye huwandu hwemapini, uchideredza kudiwa kwekugadzirisa patsva kana zvikamu zvakagadzirwa. Shandisa maitiro ekugadzirisa otomatiki kuchengetedza mhando yakafanana, kuderedza mitengo yekugadzirisa patsva uye marara, izvo zvinogona kudhura.

Pamusoro pezvo, shandisa nzira dzekushandisa mari shoma dzemapakeji ePLCC nekusarudza iwo emaapplications kana hunhu hwawo hwakakwana, uchidzivisa kushandisa mainjiniya akawandisa nemapakeji anodhura akadai seQFP kana BGA kana zvisingadiwi. Kutarisira kupisa zvakanaka, sekushandisa mhinduro dzekutonhodza dzakakwana, kunogonawo kuwedzera hupenyu hwezvikamu, zvichideredza mitengo yenguva refu inokonzerwa nekukundikana nekutsiva.

Chekupedzisira, tora mukana wekuona hwindo rekutarisa rePLCC mapakeji ekudzora mhando, kuve nechokwadi chekukurumidza kuonekwa kwehurema uye kudzikisira mukana wekugadzirisa kunodhura kuzasi. Panyaya dzakaomarara, funga nezve kuburitsa kune hunyanzvi masevhisi kuti udzivise kukanganisa kunodhura uye kuve nechokwadi chekuita nemazvo, pakupedzisira uchichengetedza pane zvinogona kugadziriswa uye mari yewaranti. Nekushandisa zvine hungwaru PLCC kurongedza, unogona kuwana yakakosha mari yekuchengetedza uchichengetedza zviyero zvemhando yepamusoro mumapurojekiti ako emagetsi.

mhedziso

PLCC mapakeji anoramba ari chinhu chakakosha mune akawanda emagetsi maapplication, achipa chiyero chemutengo-kushanda, kuita zvakasiyana-siyana, uye nyore kuungana. Kunyangwe zvisingakwanisi mukushanda kwekupisa uye kumhanya kwechiratidzo, iwo akakosha mune chaiwo mamiriro, kunyanya mumasisitimu enhaka uye maapplication anoda kusimba. Kunzwisisa dhizaini yavo, mhando, mabhenefiti, uye nzira dzekugadzirisa matambudziko kunovimbisa kuti PCB dhizaini nyanzvi dzinokwanisa kushandisa nemapakeji ePLCC mumapurojekiti avo, kuchengetedza kuvimbika uye kugona kwemasystem avo emagetsi.

Nekugona kuomesesa kwePLCC mapakeji, mainjiniya anogona kusimudzira kugona kwavo dhizaini, kuve nechokwadi chekuita kwakakwana uye hupenyu hurefu hwezvigadzirwa zvavo. Gwaro iri rakazara rine chinangwa chekupa ruzivo rwakakosha uye ruzivo runoshanda, kupa nyanzvi kuti dziite sarudzo dzine ruzivo mumabasa avo ekugadzira PCB.
