Kunyangwe kusati kwave kukonzeresa-isina lead kunetsa, chipiri chekutengesa mashandiro akaunza matambudziko akaoma.
Kuwana kugadzirwa kwepamusoro uye vhoriyamu kusangana kuburikidza nekuisa ne solder muswe zviteshi zvaisaita nguva dzose.Izvi zvinonyanya kukosha muindasitiri yemotokari, uko mahombe akaumbwa ekubatanidza anogara achishandiswa kune ese masimba uye ekudzora masaini.Vagadziri vanofanirwa kusanganisa inoshanda otomatiki gungano rekubatanidza uku vachideredza nyaya dzine chekuita nekutengesa maitiro.Kuzadzisa chinangwa ichi, tekinoroji-yekukodzera tekinoroji inobvumira kuisirwa kwemuchina wekumhanya kwepini imwe chete kana akawanda anowirirana nematerminal ayo asingade matanho anotevera ekutengesa uye anopa mwero wepamusoro wesimba rekuchengetedza.
Press-fit tekinoroji, inozivikanwawo seyekupindira fit kana friction fit, yakaratidza uye inoshandiswa zvakanyanya muindasitiri yemotokari neyekufonera.Muzviitiko zvakawanda, yakabvisa soldering yepini-yakanyanya interconnect masisitimu.Iri kuramba ichishanduka kusangana nematambudziko matsva ekugadzira uye kugadzirisa huwandu hwakakura hwezvinodiwa zvechigadzirwa.
Dambudziko guru rinosanganisira kuwana chiyero chakakodzera pakati pesimba rekuisa rinodiwa uye huwandu hwekuchengetedza (semuenzaniso simba rekubvisa rinodiwa kubvisa pini).Simba rekuchengetedza rinofanirwa kunge riri padyo sezvinobvira kune simba rekuisa kuti riwane kusimba kukuru kwekubatanidza.Kunyanya deformation yepress-fit chikamu kunogona kukonzera kuderedzwa kwesimba rakajairwa pakati pepini inowirirana nedhiramu regomba.Inodzikisira simba rekuchengetedza uye mashandiro pamusoro pehupenyu hwechigadzirwa.
Gasi Tight Fit ine Yakanyanya Kuchengeta
YICHUAN inopa mhinduro-inokwana mhinduro dzinopa vatengi vedu vasina kutengesa, vane simba remukati, gasi-yakasimba yekubatanidza.Yedu inopindirana yepini-yakakodzera pini yakayedzwa zvakanyanya kune ese maindasitiri zviyero.Iko kukweshana kwepini yekutsikisa-fit inopa gasi yakasimba yekubatanidza ine simba rekuchengetedza rakakwana.Iyo inochengetedza yakakwirira yakajairika simba pane yakapfava kuburikidza negomba (PTH) yeakadhindwa redunhu bhodhi, uye inobvisa kudiwa kwekutengesa.Mushure mekuiswa kwepini inowirirana iyo yekubatanidza inopedzwa nenzira inoshanda kwazvo
Sezvo pini yepini yeziso-ye-tsono chikamu inotora deformation yefit fiction uye haikanganise iyo yakapfekwa neburi.Ndosaka zvichikwanisika kubvisa pini yekutsikisa-yakakodzera pane imwe nguva pasina kukuvadzwa kuPCB kana kudiwa kwekuwedzerazve.Zvinokwanisika kubvisa zvakakanganiswa pini-fit pini nerubatsiro rwechishandiso chemaoko chiri nyore.Inobvumira kuisa pini itsva mune yekare yakaputirwa neburi.
Iyo inoenderera mberi yakananga kune yakanaka-pitch surface Mount tekinoroji (SMT) dhizaini inoitwa zvakare nyore nekushandisa press-fit pini tekinoroji.Sezvo nzvimbo pakati pekubatanidza inova diki, matambudziko ekutengesa anowedzera zvakanyanya.Maitiro ese anofanirwa kudzorwa zvakanyanya.Deposition ye solder paste inofanira kubatwa mukati mezvibvumirano zvakasimba kudzivirira kubhuroka kana solder-bhora pakati pemapads.Izvi zvinoda kuderedza solder vhoriyamu kupokana ne SMT uye pini-in-paste yekubatanidza zvinodiwa.Vanowanzoda hombe solder fillets kuvimbisa kusimba kwekunze kwemuviri kubatanidza masimba.Mapini anopindirana anopindirana anotendera mugadziri kubvisa zvinonetsa, midziyo yakasarudzika uye mari yekuwedzera ine hukama neinongedzo yekubatanidza pamabhodhi madiki eSMT.
Yakagadzirwa uye Yakarongedzerwa Kufambisa Otomatiki Maitiro
Ese mapini anodhinda-anokodzera anounzwa ari anoramba akadzokororwa mafomati senge munhu kana akawanda chinzvimbo chekubatanidza mativi kuti aiswe nemichina yekupinza pini inomhanya.Izvi zvinoita kuti tekinoroji-yakakodzera tekinoroji inyatsobatanidzwa mukati meiyo chero iripo SMT kana kuburikidza-gomba kugadzirisa mitsara.Mapini anodzvanya-anokodzera anogona kuiswa otomatiki sedisiki yekubatanidza mune chero inodiwa pateni, kana kuiswa seyepini musoro wekubatanidza, precut kune chero hurefu hunodiwa uye / kana chinzvimbo kuverenga.Zvichienderana nezvinodiwa neapplication, misoro yepini-inokwana inowanikwa seimwe-ne (1 x 1, 1 x 2, zvichingodaro) kana maviri-by (2 x 2, 2 x 3, nezvimwewo) zvigadziriso.
Nekuti iyo inoteedzera yakazara-inopindirana inopindirana inopedzwa mune imwechete nhanho, iyo otomatiki yekuisa mashandiro inogona kubatanidzwa pane chero nzvimbo mukuyerera kwese kwekugadzira.Kazhinji, nhanho yekuisa pini yekutsikirira inoitiswa kana pedyo nekumagumo kwemaitiro;mushure mezvose zvikamu zveSMT zvakatoiswa uye zvinotengeswa zvakare.
Kushandisa solderless press-fit tekinoroji ye-on-board interconnects inobvumira maitiro ese eSMT (solder paste screening, kumusoro & nechepasi side componement placement, reflow, etc.) kuti iitwe yakazvimirira zvachose pakusangana kwekubatanidza.Izvi zvinoderedza mutengo nematambudziko ekubatanidza nhanho dzakaoma dzekuita senge isinganzwisisike-fomu yekuiswa kwezvibatanidza, pinning kuburikidza nenamira, yechipiri soldering uye / kana manyore maitiro.Kuchinja kubatanidza solder nepress-fit tekinoroji inovandudza otomatiki uye mabhizinesi maitiro.
Pamusoro pekurerutsa kuyerera kwekugadzirwa kwese, kuisa ma solderless interconnects sedanho rekupedzisira zvakare kunodzivirira njodzi yezvimedu uye mutengo wekugadzirisa zvakare zvinogona kuitika kubva mukuyedza kugadzirisa yakaoma solder process kumusoro.Mamwe matanho ekugadzirisa akatopera uye, pakuiswa kwepini-fit pini kana materminal, gungano rekupedzisira rinoitwa uye rakagadzirira kuyedzwa.
YICHUAN inopa yakakwira-kumhanya pini yekuisa michina mumasikisi akasiyana emisika muNorth America, Europe neAsia.
