jeki ya mahedifoni yopanda mutu SMT Pj-381-4p jeki ya mahedifoni yopanda mutu
Ubwino wa malonda:
Kutumiza mwachangu, zitsanzo zaulere, zinthu zokhala ndi lipoti la mayeso a SGS RoHS, moyo wa kuzungulira wopitilira nthawi 5000,kukana kutentha kwambiri kwa chigamba,utumiki wotsimikizika pambuyo pa malonda, chithandizo chaukadaulo ndi malingaliro abwino a ntchito
Magawo ogwiritsira ntchito:
Zogulitsa zamakutu, zida ndi zida, zamagetsi, zida zapakhomo, zinthu zachitetezo, zida za hi-fi, zida zamawu
Mphamvu za fakitale:
Kampaniyo yakhala ikugwira ntchito kwa zaka 13, ndipo yapambana satifiketi ya ISO9001, ma patent satifiketi angapo, makasitomala ogwirizana oposa 5300, makasitomala ambiri ochokera m'makampani omwe atchulidwa, antchito 106, zida 12 zopunthira, makina 18 opangira jakisoni, makina 26 osonkhanitsira okha, makina 32 oyesera okha, makina 21 oyesera okha, makina 12 oyesera moyo ndi zida zina 25 zoyesera.
Katundu wathu akukwaniritsa zofunikira pansipa ndipo akhoza kupambana mayeso awa:
1) kutentha kwapakati：gwiritsani ntchito mkati mwa -30~70ºc
2) Mitundu yodziwika bwino ya mlengalenga yopangira miyeso ndi mayeso ndi iyi:
(1) pakati pa thupi ndi kondakitala: 5ºc mpaka 35℃
(2) pakati pa owongolera kuti asalumikizane：45% mpaka 85%
(3) kupanikizika：86kpa mpaka 106kpa
3) mphamvu yolumikizira ndi kuletsa
Muyeso uyenera kupangidwa mutalumikiza ndi kulumikiza pogwiritsa ntchito pulagi yokhazikika katatu, mphamvu yolumikizira ndi kulumikiza ndi 5-15n
4) mphamvu yomaliza
Kulemera kosasinthika kwa 0.1n/m(1kgf/cm) kuyenera kuyikidwa kumapeto kwa terminal kwa mphindi imodzi mbali iliyonse.
Sipadzakhala kuwonongeka kulikonse pa terminal monga ming'alu, kumasuka kapena magetsi osewerera, ndipo makhalidwe a makina ayenera kukwaniritsidwa.
5) kukana kukhudzana
kuyezedwa pa mphamvu yaying'ono()100m kapena kuchepera）1000hz, kukana kukhudzana ≤30mω
6) kukana kutenthetsa
Ikani magetsi a 500v dc kwa mphindi imodzi ku magawo otsatirawa, kenako muyeso uyenera kupangidwa:
(1) pakati pa thupi ndi woyendetsa
(2) pakati pa owongolera kuti asalumikizane
(3) pakati pa ma conductors sayenera kukhala pamene pulagi yaikidwa dc 500v 1 min kukana kutchinjiriza ≥100mω
7) mlingo：dc 30v 0.2a
8) mphamvu ya dielectric: ac 250v ims (50~60hz) ya mphindi imodzi yamagetsi oyenda: 0.5ma
(1) pakati pa thupi ndi woyendetsa
(2) pakati pa owongolera sayenera kulumikizana
(3) pakati pa ma conductors sikuyenera kukhala pamene pulagi yaikidwa dc 250v mphindi 1
9) mayeso oti solderability ikwaniritsidwe
pamwamba pa malo olumikizira magetsi payenera kumizidwa 1mm mu bafa ya solder ya 240±5℃ kwa masekondi 3±0.5.
10) kukana kutentha kwa mayeso a soldering mikhalidwe yobwezeretsanso soldering:
kutentha koyambirira: kutentha pamwamba pa zojambulazo zamkuwa kuyenera kufika 180℃ .120s pcb itatha
Kulowa mu chipangizo chosokera. kutentha kwakukulu: kutentha pamwamba pa zojambulazo zamkuwa kuyenera kufika kutentha kwakukulu kwa 260±5℃ mkati mwa masekondi 20.
11) kukana mayeso a kutentha kwa soldering
njira yosokera chitsulo:
kutentha pang'ono 330±5℃ ntchito
nthawi ya chitsulo chosungunula3±0.5 sekondi
komabe kupanikizika kochulukirapo sikuyenera kugwiritsidwa ntchito pa terminal
13) mayeso a chinyezi
jeke iyenera kusungidwa kutentha
ya 40±2℃ ndi chinyezi cha 90% mpaka 96% kwa maola 96, ndiye kuti jeke iyenera kusungidwa pamalo abwino kwa ola limodzi pazinthu zina.
14) mayeso a kutentha
Thefonijeke iyenera kusungidwa kutentha kwa 70±2℃ kwa maola 96，ndipo kenako idzayang'aniridwa ndi mbasurbm yobwezeretsa
15) mayeso ozizira
jeke iyenera kusungidwa kutentha kwa -25±3℃ kwa maola 96 kenako iyenera kuyikidwa pansi pa zikhalidwe zowongolera zobwezeretsa kwa ola limodzi pambuyo pake
16) mayeso a moyo
pamlingo woyenera()katundu wosayambitsa）
Kulumikizana ndi kulekanitsidwa kuyenera kuchitika ma cycle 5000 pa liwiro la ma cycle 10 mpaka 20 / mphindi
17) mayeso a kuzizira ndi kutentha
Chophimbacho chiyenera kuchitidwa zinthu zisanu zotsatirazi zomwe zawonetsedwa pachithunzichi, kenako chibwezeretsedwe ndikuloledwa kukhalabe m'chipindamo kwa mphindi 30..
TApa sipadzakhala kusintha kapena ming'alu mu gawo lowumbidwa.&mphamvu yochotsera: 3 mpaka 20n
kukana kukhudzana:max.30mω
kukana kutchinjiriza: min.100 mω
Voliyumu yokhazikika ya dielectric: 500vac/min (pakati pa ma terminal)
