QFP Kutenga, Gungano, uye Packaging Solutions

KuHighleap Electronics, tinodada nekuva mupi wepamusoro wemabasa ekugadzira nekubatanidza maPCB emhando yepamusoro. Nekunzwisisa kwakadzama kwezvinodiwa zviri kuchinja muindasitiri yezvemagetsi, tinopa mhinduro dzakakwana dzakagadzirirwa zvinodiwa netekinoroji yemazuva ano. Chimwe chezvinhu zvakakosha pakubatanidza maPCB kusarudzwa kwemapakeji ekubatanidza macircuit (IC) , izvo zvinokanganisa zvakananga mashandiro, saizi, uye mitengo yekugadzira. Imwe yematekinoroji anonyanya kushandiswa ekurongedza iQuad Flat Package (QFP). Muchinyorwa chino, tinotarisa zvakadzama nezvekurongedza kweQFP, mhando dzayo, uye kukosha kwayo munyika inogara ichichinja yekubatanidza maPCB.

Kunzwisisa Quad Flat Package (QFP) Technology

Iyo Quad Flat Package (QFP) inyanzvi yepamusoro-soro tekinoroji (SMT) inoshandiswa kudzimba dzakabatanidzwa maseketi (ICs). Iyo inoratidzirwa neyakafuratira, ine rectangular chimiro ine mitoo inokwira kubva kune imwe neimwe yemativi ayo mana, anowanzo kunzi "gull-wing" inotungamira. Aya anotungamira anofambisa maitiro ekutengesa uye anopa kugadzikana kwemichina kana pasuru yacho yakaiswa paPCB. Kutorwa kwakapararira kweQFP mumaindasitiri akasiyana - kubva kumagetsi evatengi kuenda kumidziyo yekutaurirana - kwave kufambiswa nekusiyana-siyana kwayo, compactness, uye kushandisa zvakanaka nzvimbo paPCB.

QFP mapakeji anobata kune dzakasiyana siyana maapplication ayo anoda pakati nepamusoro pini kuverenga. Izvi zvinosanganisira microcontrollers, processors, memory chips, uye mamwe akawanda maIC. Iwo magadzirirwo akajairwa eQFP anosiyana maererano nehuwandu hwepini, pini pitch (chinhambwe pakati pemitoo yepedyo), uye zviyero zvepasuru, zvichibvumira mainjiniya kusarudza iyo yakakodzera QFP kune zvavanoda chaizvo.

Zvinhu zvakakosha zveQFP Packaging

Pin Count uye Lead Pitch

QFP mapakeji anowanzo kuuya nemapini ekuverenga kubva pa32 kusvika ku304 mapini, achipa mhinduro inoshanduka yezvishandiso zvinoda zvese zvidiki uye hukuru huwandu hwekubatanidza. Iyo pini pitch inowanzobva pa 0.4mm kusvika 1.0mm, zvichienderana nehukuru uye kuoma kweIC. Iyo diki inotungamira inogonesa yakakwira pini density, iyo yakanakira mamwe akaomarara ICs uko optimization yenzvimbo yakakosha.

Gull-Wing Inotungamira

Iyo gull-wing inotungamira ndeimwe yeakamira maficha eQFP. Aya anotungamira anowedzera kunze kubva kumativi epasuru uye akakotama kuita "gull-wing" chimiro. Iyi dhizaini inovimbisa kuti inotungamira inowanikwa nyore kune pamusoro-mount soldering. Iyo gull-wing chimiro inosimudzira tsigiro yemagetsi panguva yekushambadzira uye inova nechokwadi chekubatana kwakachengeteka, kunyangwe pasi pemagetsi kushushikana.

Compact Size uye Kubudirira

QFP mapakeji anozivikanwa nekuenderana kwawo, achiaita akanakira maapplication uko kunetsa kwenzvimbo inyaya. Dhizaini yavo yakafuratira haingoite kuti zvive nyore kuunganidza asi zvakare inogonesa kushandiswa kwebhodhi nzvimbo, ichisiya nzvimbo yezvimwe zvikamu. Izvi zvinonyanya kukosha mumaindasitiri akaita sevatengi vemagetsi, uko kudzikisira saizi uchichengetedza mashandiro kwakakosha.

mhedziso

Pa Highleap Electronics, tinonzwisisa kukosha kwekusarudza iyo chaiyo yekurongedza mhinduro yePCBs ako. Yedu yepamusoro PCB yekugadzira uye masevhisi masevhisi anovimbisa kuti zvishandiso zvako zvemagetsi zvinosangana nepamusoro-soro maitiro uye kuvimbika. Kunyangwe iwe uri kushandisa QFP, TQFP, LQFP, kana chero imwe mhando yekurongedza, isu tinopa akarongedzerwa mhinduro dzinosangana nezvinodiwa zvekushandisa kwako.

Sezvo kudiwa kwezvishandiso zvine simba uye zvakabatana zvemagetsi zvichiramba zvichikura, matekinoroji ekurongedza seQFP acharamba ari chikamu chakakosha chePCB musangano maitiro. Nekuramba tiri padanho rekucheka tekinoroji iyi, isu tinoenderera mberi nekubatsira vatengi vedu kugadzira yakakwirira-kuita, zvigadzirwa zvakavimbika zvinosangana nezvinoda kuitika zvemusika.
